Kia EV3 EPA driving range revealed with up to 321 miles

Kia's compact electric SUV, the EV3, is close to going on sale in the US, and the EPA has now released official range numbers ahead of launch. The standard-range front-wheel-drive model, with a 58.3 kWh battery, gets 221 miles per charge. The long-range front-wheel-drive version, with an 81.4 kWh battery, gets up to 321 miles. An all-wheel-drive version using the same larger battery is rated at 280 miles. These figures are close to what Kia had already estimated. For homeowners thinking about EV charging at home, a few details stand out. Kia says the standard-battery EV3 can fast-charge from 10% to 80% in 29 minutes on a DC fast charger. All North American EV3 models come with a built-in NACS charging port, the same plug Tesla uses, so drivers can charge at Tesla Superchargers without needing an adapter. That matters if you're weighing home charging equipment or thinking about which public charging networks you'd rely on. Kia hasn't announced pricing yet, but the EV3 is expected to start around $35,000, positioning it as an affordable option compared to some other EVs, and slightly larger than the Chevy Bolt EV and Nissan LEAF. If you're considering an EV purchase alongside home upgrades like a charger installation, this is one more affordable model entering the US market soon, though exact pricing and any rebates or incentives tied to it haven't been confirmed yet.

Canada’s wildfire season is taking a heavy toll on First Nations

This is a news item outside our usual focus on home energy upgrades, but here is a plain summary. Canada's wildfire season has hit First Nations communities hard this summer. As of early August, 601 wildfires were burning nationwide, with 113 classified as out of control. The fires have affected at least 81 First Nations and forced more than 9,100 people from their homes since April, with over 2,500 still displaced. In British Columbia, the Bradley Creek wildfire destroyed more than 30 homes belonging to Okanagan Indian Band members and about 200 other structures near Vernon. The band's chief said its firefighters lacked proper wildland firefighting equipment, having only a truck built for structural fires rather than rough terrain. In Ontario, a fast-moving fire devastated Namaygoosisagagun First Nation, and questions have arisen over whether the community will get federal rebuilding help since it isn't formally recognized as a First Nation. At least 12 First Nations in Ontario have been fully or partially evacuated, prompting a call for a public inquiry into the province's response. Other communities have raised concerns about emergency alerts not being provided in Indigenous languages, delays in getting information about changing fire risks, and disputes over who decides when it's safe to return home. In one case, a community objected when the government lifted evacuation orders while large fires still burned nearby, threatening the only road out. This story concerns wildfire response and recovery for Indigenous communities in Canada, not home energy upgrades or rebates, so there's no direct action for homeowners here.

Schneider Electric Canada Strengthens Commercial Leadership to Help Customers Navigate the New Energy Landscape

Schneider Electric Canada, a company that makes energy and building technology, has promoted two executives to expanded leadership roles. Shaun MacGarvie is now Vice President of National Sales, combining the company's contractor, end-user, and channel sales teams into one national group. Sophie Chadefaud is now Vice President of Marketing, with a broader role covering marketing, partner relationships, sales support, and online sales. The company says these changes are meant to help it work more closely with customers on energy management, upgrading infrastructure, cutting carbon emissions, and adopting digital tools. Schneider Electric's president in Canada, Emily Heitman, said the moves are meant to help the company deliver expertise and support to customers working through energy and business changes. This is a corporate leadership announcement, not a new program, rebate, or product. Schneider Electric primarily serves businesses, contractors, and large facilities rather than individual homeowners directly, so this reorganization does not create any new savings, incentives, or equipment options for your house. If you're planning an energy upgrade — such as a heat pump, better insulation, or electrical panel work — this news doesn't change your options or eligibility for any rebate program. It's worth knowing mainly as background on how one large energy technology supplier is restructuring its Canadian sales and marketing operations.

ACMobility Sets Up Chargers Supporting Public Transport

In the Philippines, ACMobility is expanding electric vehicle charging stations to support public transportation, working with Basic Energy Corporation and Grab Philippines. The company is building charging hubs along major roads to keep electric buses, taxis, and ride-hailing cars running, and it's rolling out a digital system called ChargeFleet that lets Grab drivers charge up during shift changes without using physical payment cards. The charging stations, built with Basic Energy, will sit along busy commuter routes including the South Luzon Expressway, EDSA, and several sites in Quezon City, Pasay, Mandaluyong, Cainta, and Marikina, adding to existing locations on the North Luzon Expressway and in Alabang. Some sites will offer fast direct-current charging alongside standard alternating-current units. Separately, a program called Iwas Taas Pamasahe lets local bus operators switch to electric buses with no upfront cost, with full ownership transferring after five years. This is infrastructure and fleet news rather than something that changes what's available to individual homeowners. It does not involve home charging equipment, rebates, or upgrades you'd install at your house. If you drive an EV in the Philippines, it may mean more charging options along common routes over time, and if you use Grab's electric taxi or ride-hailing service, the company is working to make those vehicles easier to keep charged and on the road.

China sales numbers are in: EVs up while everything with an engine collapses

New sales figures out of China show a clear split: battery-electric cars keep growing while every type of vehicle with a gas engine is falling fast. In July, fully electric car sales rose 6% from a year earlier, while plain gas car sales dropped 44%. Plug-in hybrids and range-extended electric vehicles (cars with a battery and motor plus a small gas engine that helps power them) also fell, dragging down the combined total for all plug-in vehicles even though pure electric cars alone are doing well. Gas-only cars now make up a shrinking share of a shrinking market, while electric cars set a record 65% share of retail sales in China. The bigger picture: as gas and oil prices have swung higher this year, more buyers in China and elsewhere are choosing electric cars instead. China's electric vehicle exports jumped nearly 148% in July compared with the year before, meaning more of these cars are headed to other countries, adding to a broader global rise in electric vehicle sales. For a homeowner, none of this changes anything directly about your house today, but it's a sign of where car buying is heading. If you're weighing whether to add an electric vehicle charger at home or pair one with rooftop solar down the road, this trend suggests electric vehicles are becoming a bigger part of the market, not a smaller one, and battery costs and charging options are likely to keep improving as scale increases.

Hyundai launches the range-topping IONIQ 9 Calligraphy Black Ink in the UK and Europe

This news is about a new vehicle trim, not a home energy upgrade, so it doesn't affect your house or any rebate program. Still, here's what happened: Hyundai is rolling out a new top-of-the-line version of its electric IONIQ 9 SUV, called the Calligraphy Black Ink, in the UK and Europe. It sits above the current Calligraphy trim as the new flagship model. The Black Ink version is mostly about looks and price, not new technology. It uses the same dual-motor all-wheel-drive setup and 110-kWh battery as the existing Calligraphy trim, putting out 422 horsepower and a rated range of up to 372 miles. What's different is styling: a blacked-out Hyundai emblem, new 21-inch wheels, a gloss black rear trim piece, and an all-black leather interior. In the UK and Europe it comes in black or white paint; in the US it will only be sold in black. Pricing starts at £79,320 (about $107,000) in the UK and €89,950 (about $104,000) in Germany. Hyundai has not announced a US price yet, but based on the cost of the current top Calligraphy trim, the US version is expected to run around $85,000 when it arrives. None of this involves home electrification incentives, EV chargers, or utility rebates — it's simply a new luxury trim for an existing electric SUV.

2027 BYD Seal 06 Comes with Lidar

This is a car news item, not a home energy upgrade story, but here's what happened. BYD, the Chinese automaker, is launching an updated 2027 version of its Seal 06 electric car. The new model adds lidar (a sensor that helps a car's driver-assist system detect objects around it) built into the roof and windshield area, along with an upgraded driver-assist system called God's Eye B. The current 2026 version, by comparison, uses a simpler system called God's Eye C and has no lidar. The updated car also gets more power, with output rising from a range of 110 to 160 kilowatts up to 120 to 240 kilowatts. It comes in both a fully electric version and a plug-in hybrid version. The 2026 model sells for 109,800 yuan, or about $16,273, though pricing for the new 2027 version has not been confirmed. BYD sold more than half a million units of the Seal 06 last year in China. For homeowners, this is not directly relevant to insulation, heat pumps, or home electrification rebates. It is simply a look at how quickly Chinese electric vehicle makers are adding advanced sensors and boosting power in mass-market cars. If you are weighing an EV purchase alongside home energy upgrades like a heat pump or an EV charger install, it is a reminder that vehicle technology and pricing in this segment are moving fast, though this particular model is not yet sold in the United States.

Ukraine debuts mine-resistant all-wheel drive combat electric motorcycle

This story is about military technology, not home upgrades, but here's what happened. Ukraine's Ministry of Defense has approved a new electric motorcycle called the MUL.E for battlefield use. It's an all-wheel-drive bike with two electric motors, built with wide, low-pressure tires that spread the vehicle's weight over a larger area. That design lowers ground pressure enough to reduce the risk of setting off pressure-triggered anti-tank mines, though the makers are clear it isn't "mineproof" and mixed minefields with anti-personnel mines remain dangerous for any vehicle. The bike runs on battery power, which makes it far quieter than a gas motorcycle, useful for scouting or moving supplies near front lines without being heard or spotted. Ukraine has already fielded electric two-wheelers for similar stealth work. The MUL.E gets about 62 miles of range per charge, but it also carries an onboard gas generator, so troops can recharge batteries with fuel instead of needing charging stations. That same generator lets the bike act as a portable power source for other field equipment. It can also tow cargo trailers over rough terrain that would stop larger trucks or jeeps. This fits a broader pattern of militaries, including the US and Canada, testing electric bikes for their quiet operation. There's nothing here that applies to home energy upgrades or rebates.

Avatr 07L Launches in Big Segment

This is a car launch, not a home energy story, but here's what happened: the Chinese automaker Avatr, backed by Changan, CATL, and Huawei, has launched a new electric SUV called the 07L, priced from 219,900 yuan (about $32,590) for a limited time, with other trims running up to 279,900 yuan ($41,480). All versions use a 89.33 kWh battery from CATL and can charge very fast, going from 30% to 80% in under 10 minutes thanks to an 800-volt charging system. Range on the base and mid trims is rated at 725 kilometers (450 miles), while the faster Ultra trim gets 650 kilometers (404 miles) — though these are Chinese CLTC ratings, which tend to run higher than U.S. EPA estimates. Every version comes with Huawei's driver-assistance and cockpit software, with the higher trims getting more advanced sensors for automated driving features. For a homeowner thinking about home energy upgrades, this doesn't have direct bearing — the 07L is not sold in the U.S. and isn't tied to any rebate or incentive program here. It's worth knowing about mainly as a sign of how fast EV technology and fast-charging batteries are advancing in China, which can eventually shape what charging equipment and EV options show up in other markets, including for homeowners considering a home charger down the road.

Waymo CEO: Vision-Only Self-Driving Safety Curve Flattens “Way Too Early”

This is a story about self-driving cars, not home energy upgrades, so it has no direct bearing on your house or any rebate program. It's worth a quick note only because Retrofit Relay tracks broader tech and energy news. Waymo's co-CEO, Dmitri Dolgov, spoke recently about why the company builds its robotaxis with a mix of sensors rather than cameras alone. Waymo uses cameras, lidar (a sensor that measures distance using laser light to map the 3D shape of surroundings), and radar together. He argued that camera-only systems can match human driving but hit a safety ceiling too soon if the goal is a self-driving car that performs far better than a person. Cameras struggle in glare or darkness, he said, while lidar and radar keep working in poor light and bad weather like fog, rain, or snow, and radar can also directly measure how fast other objects are moving. The comments were widely read as a pointed contrast with Tesla, which relies on cameras alone for its "Full Self-Driving" system. Dolgov's argument is that more sensors mean more complexity and cost, but also a higher ceiling for safety performance over time. None of this changes anything about home electrification, insulation, heat pumps, or rebate programs. It's simply a look at how two companies are approaching self-driving technology differently, with no action needed on your part.

Burchda Y3 AWD — Powerful, Long-Range, All-Terrain Electric Bike

A new electric bike on the market, the Burchda Y3 AWD, is aimed at riders who want power and range for off-road use rather than commuting. It runs a dual-motor, all-wheel-drive setup that peaks at 5000 watts, hits a 40 mph top speed, and can climb steep 35-degree grades. A 52-volt, 30-amp-hour battery gives it up to 100 miles of pedal-assist range, and the battery pops out so you can carry it inside to charge instead of plugging in the whole bike. It has full suspension, hydraulic disc brakes, and 26-by-4-inch fat tires built for sand, snow, mud, and rough trails. The bike can carry up to 400 pounds, including racks or gear, and comes with an 800-lumen headlight and handlebar mirrors. It currently costs $1,199, includes a two-year warranty, and ships free within the United States. This is a product announcement, not a policy or rebate story, so there is no program or incentive tied to it. If you are weighing an e-bike purchase for trail riding, hunting trips, or other rough terrain rather than everyday street use, the specs here — power, range, tire size, and price — give you a concrete point of comparison against other e-bikes you might be considering. It does not affect any home energy upgrade or rebate program.

Tesla recall 20,000 Model 3/Y for headlights that are too bright

This is a car recall, not a home energy story, but here's the rundown if you or your household drives one of these cars. Tesla is recalling more than 20,000 Model 3 and Model Y vehicles because their low-beam headlights are too bright. The recall covers Model Y cars from 2020 to 2023 and Model 3 cars from 2017 to 2023, all with a specific headlight assembly supplied by Marelli Automotive Lighting. The federal brightness limit is 125 candela, and Tesla's headlights tested as bright as 230 candela. The problem has been known for a couple of years. A Canadian lab flagged the headlights as out of spec in 2023, and Tesla confirmed the issue itself. The company tried to limit the recall to a smaller group of cars and asked federal regulators to let it avoid a full recall, arguing the bright lights hadn't caused any accidents. Regulators denied that request in July, which led to this recall. Unlike many Tesla recalls that get fixed with a software update, this one appears to need a physical repair, meaning new headlight hardware and installation labor. Tesla notified its sales locations last week, and owners of affected vehicles will get a notice by mail by September 15. That notice will explain the next steps for getting the headlights replaced.

Cadillac will hand-build a custom Escalade IQ for you, but it will cost an extra $55,000

This news is about a luxury vehicle option, not a home energy upgrade, so it doesn't affect your house or any rebate program. Still, here's what happened. Cadillac has launched a new customization program for its electric Escalade IQ SUV called "Curated by Cadillac." Buyers can work with a design concierge to pick from more than 160 exterior colors and finishes and up to 44 interior colors, creating a one-of-one vehicle. Each one is hand-built and hand-painted at Cadillac's Artisan Center in Warren, Michigan, and comes with a unique VIN and a serialized builder's badge. The catch is cost. The Curated package alone runs $54,995, on top of the vehicle's price. The Escalade IQ itself starts at $127,405, so a fully customized version lands around $182,400. The electric SUV runs on a 212 kWh battery pack (205 kWh usable) with an estimated range of up to 465 miles, and its dual-motor setup produces 750 horsepower with a 0-60 mph time of 4.7 seconds. It also includes GM's Super Cruise driver-assist system, with the 2028 model expected to be GM's first vehicle offering hands-off, eyes-off driving on highways. The custom Escalade IQ will be sold in the US and Canada for the 2027 model year, with deliveries starting in the second half of 2027. This is a high-end vehicle story, not an energy-efficiency or rebate program update, so there's nothing here that changes what's available for home upgrades.

Anker SOLIX Mega Sale offers up to 48% power station discounts + one-day-only C1000X $399 off, AeroGarden, more

A batch of home battery and outdoor gear deals is out this week, worth a look if you have been thinking about backup power for outages. Anker has launched its SOLIX Fan Fest Mega Sale, with portable power stations discounted up to 48 percent, a bonus savings code, and a free power station thrown in on some orders, with prices starting at $190. Separately, Anker is running a one-day deal on its SOLIX C1000X, a 1,024Wh power station, for $480. Portable power stations like these store electricity you can draw on during a blackout, run appliances off-grid, or pair with solar panels. Bluetti has its own one-day deal on the AC50B, a smaller 488Wh power station, for $259 — a lower-capacity option if you just need to keep a few essentials running rather than power a whole house. Bluetti also has a broader "Emergency Backup Sale" running with several other power station discounts. Beyond backup power, there are a few home and yard deals worth noting. AeroGarden's Harvest XL indoor hydroponic garden system (a self-contained setup for growing plants indoors without soil) is down to $81, its lowest price yet. The ECOVACS Ultramarine P1, a cordless robot pool cleaner, has hit a new low price. And EGO's 21-inch Select Cut and Touch Drive mower, bundled with two 6.0Ah batteries, is seeing a discount. None of these come with fixed end dates mentioned, so if one fits a project you already have in mind, it is worth checking current pricing soon.

Flock Cameras Spark Community Backlash

This isn't really an energy-upgrade story, but here's what's happening: a company called Flock Safety has installed more than 120,000 license plate reading cameras across the US, under contract with 40 percent of police departments. The cameras track passing vehicles and feed the data into a shared nationwide database, raising concerns about who can access records of where people drive and when. Pushback has grown in various places. Los Angeles and Dayton, Ohio suspended their Flock contracts over worries that immigration authorities could tap into the data. In Texas, where about 700 of the cameras operate, both progressive and conservative residents have pushed to have them removed. In some cities, including Houston, Oakland, and Grand Junction, Colorado, people have cut down, painted over, or disabled cameras themselves. A group called DeFlock lets people search for camera locations near them, and the ACLU has launched its own campaign opposing the system. A Texas congressman has introduced a bill that would require federal agencies to get a warrant before querying data from these local camera networks. None of this involves home energy upgrades, rebates, or efficiency programs. It's a privacy and surveillance debate about license plate cameras in public spaces, unrelated to weatherization, heat pumps, or utility incentives homeowners might be tracking.

Bill Seeks Changes to DOE Appliance Efficiency Program

A new bill in Congress could change how the government sets efficiency rules for furnaces, water heaters, and dozens of other household appliances. Sen. Mike Lee introduced the Energy Efficiency Reform Act of 2026 this month, aiming to overhaul the Department of Energy's Appliance Standards Program, which sets energy-use rules for about 60 household and commercial products under a law last updated in 2007. The bill would make several changes. It would lock in a "Process Rule" that governs how DOE decides whether new efficiency standards are practical and worth the cost, requiring DOE to finalize a version proposed in July 2026 within 270 days. It would also drop the current requirement that DOE review appliance standards every six years, though people could still petition for changes under stricter evidence rules. And it would add new steps DOE must follow before creating new "classes" of products, a process that can affect which features or fuel types are available to buy. The bill would also strengthen federal authority over states, blocking state laws that ban appliances based on fuel type or emissions, or that set their own standards when there is no current federal one. Supporters, including the American Gas Association, say the changes would keep options like natural gas furnaces and water heaters available and prevent efficiency rules from driving up costs. The bill has not become law yet, so nothing changes for homeowners immediately, but it could affect which appliances are sold and how efficiency standards are set in years ahead.

In North Carolina, rooftop solar is alive and well despite headwinds

Rooftop solar in North Carolina took a hit after last year's federal law eliminated the 30% tax credit for homeowners who buy panels outright. New installations dropped by two-thirds between late 2025 and early this year. But installers say business is picking back up, thanks to new ways of financing panels that don't depend on that lost credit. The big shift is leasing. Businesses can still claim a 30% tax credit for solar equipment through at least the end of next year, and companies that lease panels to homeowners (rather than sell them) can pass those savings along. Some installers now offer leases directly, while others partner with third-party leasing companies. The result: many homeowners can get solar with little or no money down and start saving on their electric bill right away. Adding battery storage can sweeten the deal further — Duke Energy customers who let the utility tap their home battery a few dozen times a year through programs called EnergyWise Home or Power Manager get a monthly payment, often around $50. Rising electric rates are also pushing more people toward solar, since Duke bills have climbed over 20% in five years, with more increases proposed. Leasing may not stick around if federal and state tax rules change, and Duke's credit for solar households' excess power is set to shrink again on January 1, 2027. Still, installers say demand is strong enough that they're seeing record sales despite the rockier market.

Congress Passes ROAD to Housing Act: What’s Needed Next for Climate-Resilient Homes?

Congress recently passed the 21st Century ROAD to Housing Act, the biggest federal housing package since 1990. It became law without President Trump's signature. The bill mainly aims to encourage more home building by changing federal housing programs and financing rules, but it also includes some pieces that touch on making homes sturdier against extreme weather: better standards for manufactured housing, expanded repair programs for homeowners and landlords, and faster disaster-recovery funding for lower-income communities over the next three years. For now, this is mostly a framework, not money in hand. The law didn't come with much new funding attached, so programs like expanded home repairs and heat-safety research still need Congress to approve actual dollars through the annual budget process. Separately, federal agencies — mainly the Department of Housing and Urban Development (HUD) — now have to write detailed rules spelling out how these programs will actually work, including new energy-efficiency standards for manufactured homes, which are set federally rather than by states. Those rules will shape how well new housing holds up to heat, storms, and flooding for years to come. One thing to watch: at the same time, the federal government is moving to repeal a flood-risk standard that required HUD-funded projects to be built for both today's and future flood risks. If that standard goes away, new federally backed homes in flood-prone areas could face higher risk. None of this changes existing rebate programs directly, but it may affect what protections and efficiency standards apply to new and manufactured homes built with federal support in the coming years.

Installing Flanged Windows – Part 5: Air-Sealing

This video walks through the inside finishing steps for installing a new window, once the outside work is done. The builder shims the window in place, then fills three sides of the gap with low-expansion spray foam, a foam that doesn't push the frame out of shape as it cures. He leaves a small gap between the shims and the back of the window's flange so foam can fill that space, which helps prevent condensation from forming inside the wall in cold weather. The shims themselves keep the window seated straight and give it something to push against when it opens and closes, so it keeps working smoothly over time. The bottom of the window gets different treatment. Instead of foam, he uses two layers of a foam cord called backer rod, then seals over it with caulk shaped like an hourglass around the rod, so it bonds to the window and the wall but not to itself in the middle, letting it flex without cracking. No foam goes in the sill because foam can trap water if the window ever leaks, while backer rod lets any water drain out instead of getting stuck. This kind of careful air-sealing around a window is what a blower-door test checks for afterward, a whole-house depressurization test that measures how much outside air is leaking in. Getting these details right at each window is part of what keeps a home's heating and cooling costs down and avoids moisture problems in the wall over time.

A. O. Smith Partners with Panasonic to Bring a CO2 Split HPWH to Market

A. O. Smith, one of the major US water heater makers, has released a new heat pump water heater called the Voltex X, built with Panasonic. Unlike most heat pump water heaters, where the compressor and tank sit together in one unit, this is a "split" system: the compressor sits outside the home and connects to an indoor tank through water lines. That design is aimed at homes that don't have room for a standard heat pump water heater, like apartments and mobile homes. The Voltex X uses CO2 as its refrigerant, which lets it work in cold weather down to -25 degrees Fahrenheit and heat water quickly without needing a backup electric heating element (a feature that normally makes these units less efficient when it kicks in). It comes in five tank sizes, including a smaller "low-boy" option for tight spaces, and can supply one home or apartment per unit. Installers surveyed for the story put pricing around $4,000 to $4,500, which is more than a typical standard heat pump water heater ($1,600 to $3,500) but in line with other split systems. If you're considering a heat pump water heater but don't have space for a standard tank-and-compressor unit, this adds another option to look into. Things to ask about if you go this route: how the outdoor water lines handle freezing weather, since that's still being tested, and the added electrical work, since the system needs both a 240-volt outdoor connection and a separate 120-volt line to the indoor tank.

Installing Flanged Windows – Part 2: Prepare the Rough Opening

This how-to video walks through the details that go into properly preparing a wall opening before a new window goes in, using an Andersen 400 Series window as the example. The builder cuts the opening in the wall sheathing, softens the sharp edges, and then focuses on two things that determine whether a window leaks over time: the air barrier and the water barrier. He ties the wall's air-sealing layer (in this case, Zip sheathing tape) across the opening so there's no gap once the window sits in place. For water, he builds what's called a sill pan, a shaped, watertight tray at the bottom of the opening that catches any water that gets past the window and directs it back outside instead of into the wall. He uses a strip of beveled wood to create a slight slope and a raised "back dam" at the inside edge, then covers it with a stretchy adhesive tape, pressing it firmly so the glue bonds completely. He notes the difference between a simple strip of tape (a sill flashing) and an actual sill pan with a back dam, which offers real backup protection if the window ever leaks. For a homeowner, the takeaway is less about doing the work yourself and more about understanding what quality window installation involves. A sill pan, back dam, and continuous air and water barrier around a window are details that affect how long a new window performs and whether small leaks turn into hidden wall damage. If you're planning a window replacement, these are the kinds of details worth asking about.

Installing Flanged Windows – Part 3: Install the Window

If you're replacing windows, this covers what happens once a window actually goes into the wall opening, and it explains why some small details matter for how long the window lasts. The builder in the video installs a window with a flange (a strip around the frame that gets nailed or screwed to the wall and sealed), and stresses a few things worth knowing if you're hiring someone for this work. First, metal clips that bolt the window frame to the framing add real structural holding power, so the window doesn't rely only on the flange to stay put during storms or high wind. Second, the shims used to level the window in the opening matter: composite shims (rather than wood ones like cedar) don't soak up water and wick it into the window frame or trim, which can cause hidden rot or paint damage over time even if the window itself is sealed correctly. The other detail is drainage. The installer leaves the bottom edge of the window unsealed and uses small "horseshoe" shims underneath it, so that if water ever gets past the window seal — from a storm, a bird strike, or just years of sun exposure — it has a path to drain back outside instead of pooling and causing damage. None of this is something you'd inspect yourself, but knowing these terms (window clips, composite shims, drainage shims) can help you ask better questions if you're getting new windows installed and want assurance the job accounts for long-term water and air performance, not just appearance.

Addressing Smart Thermostat Privacy Concerns: What Contractors Can Do To Put Homeowners At Ease

If you have a smart thermostat, or you're thinking about installing one, you may wonder what it's actually doing with your data. These devices collect things like your temperature settings, schedule, and mode to work properly, and some use sensors to track occupancy or humidity. Features like weather-based adjustments need your home's location, and "auto-away" settings that lower or raise the temperature when you leave need your phone's location. None of this is required — you can opt out of these features if you're not comfortable sharing that information, though doing so may turn off the feature that depends on it. A common worry is that a utility or the government could remotely control your thermostat. That's not how it works. Utilities offer optional programs, sometimes called demand response, that homeowners choose to join. These involve occasional events, usually shown in the thermostat's app, and you can skip an individual event or leave the program later. Separately, many thermostats let you share system data directly with a contractor you choose, which can help catch problems with your heating or cooling equipment early. As with any connected device in your home, some security is on you: use a strong Wi-Fi password, keep the thermostat's app and software updated, and check the manufacturer's privacy policy if you want more detail on what's collected and how it's protected. Connectivity doesn't have to mean giving up control — most of these features are optional, and you decide what to turn on.

Q&A Spotlight: What’s the best air-barrier for a beach house’s exposed floor?

A homeowner building on the South Carolina coast raised a tricky question about elevated beach houses: how do you air-seal and insulate a floor that has nothing but open air underneath it? Homes built on pilings near the ocean are raised up to avoid flood damage and rising sea levels, but that means the underside of the floor faces the same wind, heat, and humidity as an exterior wall — a much harder problem than a typical enclosed crawlspace. The homeowner, building in Charleston (climate zone 3A), already has a tight envelope planned, using taped structural sheathing on the walls and roof that's achieved very low air leakage (0.6 ACH50, a measure of how much air escapes a house under test pressure — lower is tighter) on past projects. The unsolved piece is the floor. His plan is to run a "smart" vapor-control membrane across the underside of the floor framing, seal it to the wall sheathing, and cover it with moisture-resistant drywall to form a garage ceiling, then fill the floor cavities with fiberglass insulation. He asked whether this makes a continuous air barrier and whether there's a better-tested way to handle that wall-to-floor transition. This is a niche construction detail mainly relevant to new coastal builds on piers, not a typical retrofit. But the underlying issue — that any exposed underside of a house needs the same careful air sealing and insulation attention as a wall or roof — is a reminder that floors over open space, garages, or vented crawlspaces are common places where homes lose energy if not sealed properly.

Is All-Electric Living Possible In A Basic Summer Home?

A homeowner with a small seasonal cabin in Connecticut shares what happened when she tried to go all-electric on very limited power. Her modular home only has 30-amp electrical service, which caps out around 3,600 watts total. That's enough to run a fridge, TV, and lights together, but not much more — turning on a coffee maker while a space heater runs can trip the breaker and cut power entirely. She swapped a propane heater for a small electric heater and fan, since her wiring couldn't support a full heat pump. For cooking, a four-burner electric stove was out of the question, so she uses a single induction burner instead, and says she's happy with how fast it heats compared to gas. Hot water comes from an existing electric water heater, but she has to plan showers ahead of time and turn the heater on and off around other appliance use to avoid overloading the circuit. Without central air, she relies on open windows, fans, and shade to get through hot days. She'd also like to add plug-in solar — small portable panels that plug into a regular outlet to offset grid electricity — but notes that Connecticut's law allowing this doesn't take effect until October 1, 2026. If you're weighing electric upgrades for an older or seasonal home, her experience is a reminder that your home's amp service, not just the appliances themselves, often sets the real limit on what's possible.

Sunrun pursues direct-sales transition amid industry headwinds

Sunrun, the country's largest provider of leased rooftop solar and battery systems, reported a rough second quarter. New customer sign-ups fell 31% compared to last year, and installed solar and battery capacity dropped 23% and 15%. One bright spot: 74% of new systems now include a battery, up from 70% a year earlier. The company is shifting away from selling through outside affiliate partners toward its own in-house sales staff, a change that has been bumpier than expected, partly because a major installation partner, Freedom Forever, went bankrupt in April. Sunrun says its direct sales have picked up in recent months. For homeowners, this mostly signals a company in transition rather than a change in what's available to you. If you're considering solar and storage from Sunrun, you may be dealing with newer, in-house sales reps rather than a local affiliate company. Battery attachment is increasingly the norm for new solar customers, which fits with many states' incentive programs that reward pairing solar with storage. The news also touches California homeowners specifically: tax breaks that exempt residential solar systems from property tax and utility user tax increases are set to expire at the end of 2026 unless state lawmakers act, which could raise costs for solar customers there. Sunrun also noted that California sales still haven't recovered to levels seen before the state's 2023 shift to its current net billing rules, which reduced compensation for solar exports to the grid.

SEG Solar opens 4 GW Texas facility, announces plan to become the nation’s largest crystalline silicon module maker

Solar company SEG Solar has opened a large new factory in Tomball, Texas, where workers assemble solar panels (crystalline silicon modules) for homes and businesses. The plant is expected to reach full output next year, adding 4 gigawatts of yearly capacity on top of the company's existing 2-gigawatt plant nearby in Houston. Combined, that's enough panels to eventually produce 30,000 modules a day at this site alone, once it employs about 500 workers. SEG also announced plans to build a second factory across the street within 18 months, adding another 4.6 gigawatts of capacity. If completed, the company says it would become the largest U.S. maker of this type of solar panel, producing around 70,000 modules a day across its Texas sites. The company also said it wants to build a plant that makes solar cells (the components inside panels that convert sunlight to electricity) in the U.S. by 2028. The timing is notable because the expansion was announced one day after the Trump administration unveiled new tariffs and a minimum price rule on imported solar cells and panels. Company leaders acknowledged they still need to figure out how to respond to those trade changes. For homeowners, none of this changes anything immediately, but more U.S.-made solar panels entering the market, combined with new tariffs on imports, could eventually affect panel pricing and availability for home solar installations.

This Mayor Didn’t Come to Washington to Talk About Energy Policy. He Came to Talk About Enfield.

The mayor of Enfield, North Carolina, a small rural town of about 3,000 people, recently visited Washington to talk about his town's plans rather than push for any specific energy policy. Enfield is planning energy-efficient affordable housing, solar installations, and what would be one of the first community-scale geothermal heating and cooling networks in the Southeast. A geothermal network like this uses the steady temperature underground to heat and cool buildings, often with lower energy use than traditional systems. The mayor argues these projects are as much about jobs and community investment as they are about clean energy. He points to families in Enfield facing some of the highest energy costs in the state, and says the projects could lower utility bills, create local jobs, and bring investment to a town that has often been overlooked. He made this case directly to congressional staff, framing federal energy decisions in terms of everyday impact rather than technical policy detail. For homeowners elsewhere, there's no direct program or deadline here. This is a story about one town's push toward geothermal, solar, and efficient housing, and about local leaders trying to show that rural communities can lead on clean energy rather than just wait to benefit from it elsewhere.

Installing Flanged Windows – Part 1: Coastal Window Basics

This is the first video in a five-part series on installing "flanged" replacement windows — the common type with a built-in strip around the edge that gets nailed to the wall before siding goes on. The builder, working on a new home on Grand Manan Island in New Brunswick, walks through why this window style holds up well in harsh, wind-and-rain-prone coastal settings, and why it's also the easier choice for future repairs, since most window installers still know how to work with flanged windows even decades from now. The project itself is a high-performance build: an 8-inch double-stud wall packed with dense insulation, a structural sheathing layer that also acts as the home's water and air barrier, and 4 inches of continuous foam insulation on the outside. That's a more heavily insulated wall than a typical house, aimed at very tight, comfortable, energy-efficient construction. The windows chosen are triple-pane models for extra insulation value and sound control, with glass suited to salt-air, storm-exposed locations. For a homeowner, the practical point is less about copying this exact wall assembly and more about the reasoning: in a standard vinyl-siding installation, which covers most homes, this style of window and its flashing details are the normal approach, and doing it right protects the house from water damage and drafts for decades. If you're weighing new or replacement windows, this series is a look at what a careful, code-plus installation involves, even if your own project won't include the extra insulation layers shown here.

Installing Flanged Windows – Part 4: Final Flashing and Head Flashing

This is part of a video series on installing replacement windows, covering the flashing steps that keep water out around a new window. After the window is fastened in place, the next step is taping the seams along the sides and across the top with flashing tape, a self-adhesive strip that seals the gap between the window frame and the wall. If a small wrinkle or gap shows up in the tape, it can be covered with another strip of tape or sealed with liquid flashing, a paintable sealant that bridges tricky spots. The last piece is head flashing, a strip installed above the window that sheds water away from the top edge. It needs to cover both sides of the window and slope slightly downward so water runs off rather than pooling. The flashing gets nailed in with corrosion-resistant roofing nails, taped along the top for a watertight seal, and tied into the wall's structural sheathing behind the siding. One tricky spot, called a reverse lap, is where an overlap runs the wrong way and could let water in; it gets cleaned and sealed with liquid flashing to close that gap. For a homeowner, this level of detail matters most if you're planning a window replacement, since sloppy flashing is a common cause of water damage and rot around windows years down the road. It's not something you'd typically inspect yourself, but knowing these steps exist can help you ask good questions if you're getting new windows installed.

What is a sodium-ion battery, and why is everyone talking about it?

A new type of home battery is getting attention as an alternative to the lithium batteries typically paired with solar panels: sodium-ion. Sodium is cheap and abundant, and these batteries are not flammable or explosive, so they don't need the heating, cooling, and fire-safety equipment that lithium battery systems require. That could make them cheaper and more compact. They also can be drained fully to zero without damage and work across a wide range of temperatures. There are a few sodium battery types. One version, called NFPP, is the one most likely to matter for home use — it's the safest and longest-lasting of the sodium options, though it stores somewhat less energy for its size than the lithium batteries (LFP) commonly used in home storage today. Companies working on this technology include Alsym, Peak Energy, and Unigrid, the last of which is specifically targeting homeowners with sodium batteries meant to compete with lithium home storage. None of these products are widely available for homes yet. Most manufacturing is still happening in China, though a few U.S. companies are building or planning American factories, with one large facility expected to open in Sacramento in 2027. If sodium batteries do reach the residential market in the next few years, they could offer homeowners a cheaper, safer storage option to pair with solar — but for now, this is still an emerging technology to watch rather than something you can install today.

Duration of power outages in Puerto Rico not caused by major events increased 19% in 2025

Power outages in Puerto Rico kept getting worse in 2025, even setting aside hurricanes and other major storms. New federal data show the average customer lost about 36 hours of power to routine, non-storm outages last year, up 19% from 2024. That's on top of an average of 29 hours a year over the past five years. For comparison, customers on the U.S. mainland typically lose about two hours a year to this kind of everyday outage, so Puerto Rico's grid is far less reliable even in a normal year. Storms and other major events added another 23 hours of outages in 2025, even though no major hurricane hit the island directly. Heavy rain and flooding in spring 2025, along with indirect effects from Hurricane Erin, still knocked out power in various places. Outages are also happening more often, not just lasting longer: the average customer had about 16 non-storm interruptions in 2025, with the number rising to roughly 17 once storm-related outages are included. The frequency of routine outages has doubled since 2021. For homeowners in Puerto Rico, this points to a grid that is becoming less dependable year over year, apart from hurricane season. If you're weighing backup power, battery storage, or other resilience upgrades for your home, this trend is useful context: outages aren't just a hurricane risk anymore, they're becoming a more regular part of the electric service, even in years without major storms.

Samsung, Oak Ridge National Laboratory testing cold climate vapor compression heat pump tech

Samsung and the US Department of Energy's Oak Ridge National Laboratory have started testing a new cold-climate heat pump technology that Samsung says can heat homes steadily even when outdoor temperatures drop below minus 30 Celsius (about minus 22 Fahrenheit). Heat pumps use a refrigerant that absorbs outdoor heat, gets compressed into a hot, high-pressure gas, then releases that heat indoors — but most models lose efficiency as it gets colder outside. Samsung's design aims to fix that. The system uses a rotary compressor design and a technique called flash injection, which adds extra refrigerant during long heating runs to keep the compressor from overheating and to hold steady performance in extreme cold. Samsung says the combination should make the unit better suited to places where a heat pump has to run continuously through harsh winters. The technology will be tested at a federal field lab in Fairbanks, Alaska, chosen because of its brutal winters — average lows around minus 40 C and a record low of minus 50 C. Samsung has not released further technical details, and there's no word yet on pricing, availability, or a timeline for turning this into a product you could buy. For now, this is research testing, not a heat pump on the market. But it points to where cold-climate heat pump technology is headed, which matters if you live somewhere winters are harsh and you've been told a heat pump won't keep up. Worth watching for future product announcements before assuming that's still true for your climate.

Meta Hides Data Center Info As it Pushes More Risks to Entergy’s Customers

If you're an Entergy Louisiana customer, a fight over who pays for Meta's massive AI data center expansion in Richland Parish is coming to a head. Entergy wants to build seven new gas-fired power plants (plus battery storage and transmission lines), totaling more than $15 billion in new infrastructure, to power Meta's growing computing needs. Meta hasn't agreed to cover all these costs, and testimony filed by consumer advocates argues that Entergy's claim the project will "benefit" regular ratepayers relies on overly optimistic assumptions. If Meta's actual electricity use comes in lower than projected, or costs run higher, customers could end up subsidizing billions of dollars in construction and fuel costs meant for Meta's data center. Three of the seven plants wouldn't even be paid off for 32 years, and if Meta walks away from its 20-year contract early, ratepayers could still be stuck covering the remainder. Meta itself isn't formally part of the regulatory case, so it hasn't had to answer questions under oath about how much electricity it actually needs or what jobs and investment it's promising. A subpoena seeking that information has so far been upheld by a judge, but Meta is appealing, and Louisiana's five elected utility regulators will vote on whether to force Meta to answer on Wednesday, August 12, 2026, at 9 a.m. in Baton Rouge. If you live in Louisiana outside New Orleans, your electric bill could eventually reflect however this case is decided. Residents can contact their state utility commissioner or attend Wednesday's public meeting to comment.

Is Base Power coming for Tesla?

Base Power, a home battery startup, just raised another round of funding, pushing its valuation to at least $13 billion. Unlike most battery makers, Base owns and runs the batteries itself rather than selling them to homeowners outright. Customers, which the company calls "members," pay an upfront fee of $100 to $700 depending on location, instead of buying the battery. Its newest model, Base Core, stores 40 kilowatt-hours of power, well above the roughly 13.5 kWh you get from a Tesla Powerwall, which typically costs around $7,000 before installation and incentives. Base started in Texas, where it also acts as an electricity retailer, and has begun expanding into other markets by selling battery capacity to utilities instead. With this new funding, the company plans to grow its manufacturing from about 40 megawatts of batteries a month to 100 megawatts by year's end, and to move into other energy products beyond batteries. A big part of that growth is aimed at data centers, not homes. Base wants to supply battery capacity to power-hungry data centers through deals known as "bring your own capacity," where a data center helps pay for local energy resources like batteries in exchange for guaranteed power. This is a broader trend in the industry, with companies like Google striking similar deals elsewhere. For homeowners, the takeaway is that a lower-cost, utility-scale alternative to traditional home batteries is scaling up fast, though availability still depends on where you live and whether Base or a similar model has reached your local grid.

Sunset of ITC means solar PPAs will do more heavy lifting

The federal tax credit that covered 30% of the cost of building new solar and wind projects is being phased out under changes to the Inflation Reduction Act. Large solar and wind projects that started construction after July 4, 2026, and were counting on that credit to make financial sense now face higher costs. A new analysis found that out of thousands of projects nationwide, hundreds of solar projects and dozens of wind projects depended on the credit to be worth building at all. Without the credit, developers are turning to power purchase agreements, or PPAs, which are long-term contracts where a buyer agrees to purchase electricity from a project at a set price. To make projects pencil out, developers need buyers willing to pay more per unit of power. Some big tech companies with heavy electricity use and strong clean-energy commitments, sometimes called hyperscalers, have deep enough pockets to absorb these higher prices or even buy the projects outright, as Google did earlier this year with developer Intersect Power. Smaller companies without that financial flexibility may struggle to sign these pricier contracts, which could slow down new solar and wind construction in some areas. None of this changes rebates or incentives for homeowners directly. It mainly affects large, utility-scale power projects and the corporations that buy electricity from them in bulk. But it is worth watching, since rising costs for new power generation, combined with growing electricity demand overall, can eventually influence local electricity rates and how quickly cleaner power sources get built in your region.

Ford reveals Fathom EV pickup prices in the US and Canada

Ford has announced pricing for its new electric pickup, called the Fathom. In the US, it starts at $28,350, plus a $1,595 delivery fee, with pre-orders opening in early 2027. In Canada, it starts at CA$38,690, which includes a CA$4,000 federal rebate through the Electric Vehicle Affordability Program; pre-orders there also open in early 2027. Both prices are for the standard-range version and don't include dealer fees. For homeowners with solar panels or backup power interest, one detail stands out: the Fathom will support bidirectional charging, meaning it can send power from its battery back into your house (called vehicle-to-home) or power other devices (vehicle-to-load). That could make it useful as a backup power source during an outage, similar to what some other electric trucks already offer. Other features include a large touchscreen, a digital key, Apple CarPlay and Android Auto, and built-in Apple Maps with real-time EV routing and charging-stop planning. The truck uses Tesla's NACS charging plug, so it should be compatible with Tesla's Supercharger network. Ford hasn't released battery size or official range numbers yet, but expects the truck to get at least 300 miles per charge, though the cheaper standard-range version may fall short of that. More details, including range figures, are expected closer to the pre-order window opening in early 2027.

Tesla exhausts its California MyFirstEV rebate allocation in 5 days

California's new MyFirstEV rebate program ran out of money for Tesla buyers just five days after it opened. The rebate gives first-time EV buyers $3,500 off a new electric vehicle priced under $50,000, or $1,750 off a used one under $25,000, taken directly off the price at the dealership with no application needed. The statewide program has $135.5 million in state funds, matched by automakers for a total pool of about $271 million, split across roughly 13 car brands. Tesla's share worked out to around $9 million before the automaker match, and buyers used it all up by August 8. Tesla ran out fastest simply because it sells far more qualifying EVs in California than any other brand, registering roughly 500 vehicles a day in the state. Only Tesla's lower-priced Model 3 and Model Y trims qualify, since the $50,000 price cap is waived only for EV-only automakers headquartered in California, like Rivian and Lucid, a category Tesla no longer fits after moving its headquarters to Texas. If you're shopping for a Tesla in California, the rebate for that brand is gone for now. Other automakers are rolling into the program on a staggered schedule: Hyundai and Lucid also started August 3, Ford, Rivian, Chevy, and Kia are set to join later in August, and Toyota, Honda, and Subaru begin in September. Whether any funding remains by the time your preferred brand comes online is worth checking before you count on the discount.

David Energy deploys plug-in batteries across 21 NYC commercial kitchens to slash power costs

Energy company David Energy has installed plug-in battery systems in 21 Wonder restaurant kitchens across New York City, working with the food company to cut electricity costs. The batteries are consumer-grade units that plug into standard 120-volt outlets, similar to what you'd use at home, rather than requiring the complex commercial hookups most business battery systems need. Software from David Energy charges the batteries overnight when power is cheap, then uses that stored energy to run refrigeration and cooking equipment during expensive peak hours. Because the batteries don't send power back into the grid, they skip the lengthy utility approval process that usually slows down battery installations in Con Edison's service area. Under the deal, David Energy owns the equipment and installs it at no upfront cost to the business, recovering its investment over a 36-month contract. The combination of shifting usage to cheaper hours, cutting demand charges, and other savings brings each location's electricity bill down by 3% to 5%, with the company breaking even on its investment in about three years. Some of these batteries also feed into two Con Edison programs, CSRP and DLRP, that pay to ease strain on the power grid during heat waves, reducing the need for backup power plants in the city. David Energy plans to build battery placement into the design of new Wonder locations opening in 2027, and is now offering the same no-upfront-cost battery setup to other New York City businesses with high power use, including laundromats, grocers, and convenience stores. This is a commercial deployment, not a residential program, but it points to plug-in battery technology becoming more common and affordable in city buildings.

Rubber Roof to Sidewall Flashing

This is a homeowner's question posted to an online building forum, not a news story, so there's no policy or program update to report. The person is re-siding a house and asking for advice on a specific, tricky detail: how to flash where an old rubber roof (EPDM) over a mudroom meets the wall of the second story above it. Getting this junction wrong is a common source of leaks, since water running down the wall has to be directed over the roof membrane rather than behind it. The homeowner's new wall assembly uses a weather-resistant barrier (a water- and air-blocking layer that wraps the sheathing), rigid fiberboard insulation, a small gap behind the siding to let moisture drain and dry, and fiber-cement siding. A materials representative suggested sealing the rubber roof to the wood sheathing with butyl tape, then sticking the weather barrier directly onto the face of that tape to tie the two systems together. The homeowner also noted that old tar paper, left over as temporary protection while removing shingles, is peeling away at the point where the roof meets the wall. For a homeowner watching your own house, the takeaway is less about a specific product and more about the general lesson: any place where a roof meets a wall is a leak risk, and it needs a real air- and water-barrier connection, not just old felt paper or tape improvised as a stopgap. If you have a similar roof-to-wall junction, it's worth having it looked at whenever you're already re-siding or re-roofing.

World’s oldest cheddar-maker slashes energy bills with novel heat pumps

A UK dairy farm is showing how heat pumps can pay for themselves fast. Barber's Farmhouse Cheesemakers, in business since 1833, started installing "milk-source" heat pumps in 2024 from startup Arkaya Energy. Instead of pulling heat from air, ground, or water like typical heat pumps, these machines draw it from fresh milk, which comes out of the cow warm. The system chills the milk down to about 35°F while using the heat it removes to warm water to nearly 198°F for washing equipment. That water previously needed a boost from an electric or fossil-fuel-fired boiler, since standard heat-recovery setups can't reach those temperatures on their own. The results: Barber's cut electricity use in half, saving about $94,000 a year and cutting carbon pollution by nearly 66 tons annually. The equipment paid for itself in under two years, which is unusually fast for this kind of investment. The farm has installed the heat pumps at three of its seven milking parlors and plans to convert the rest by 2028. This is a niche, farm-specific technology, not something for a typical house. But it's a real-world example of how heat pumps — which move heat rather than burning fuel to create it — can slash energy bills when they're matched well to a specific job, in this case handling both cooling and hot-water needs at once. The company behind it is currently focused on the UK market but has said the size of the U.S. dairy industry makes it a logical place to expand eventually.

WoodMac: New domestic inverter manufacturing could meet US solar demand

The federal government recently banned new imports of foreign-made solar inverters, the devices that convert power from solar panels into electricity your home or the grid can use. The move, from the FCC, was made over national security concerns about cybersecurity and economic risk tied to relying on foreign equipment. Right now, more than 90% of the inverters used in U.S. commercial and large-scale solar projects are imported, mostly from China and other parts of East Asia. Chinese-made inverters alone made up half the U.S. market in 2024 and 2025. A new analysis from the research firm Wood Mackenzie finds that U.S. companies have more than 100 gigawatts of new inverter manufacturing capacity planned to come online before 2028. If all of it gets built, domestic manufacturers could produce enough inverters to cover U.S. demand without relying on foreign imports. For now, domestically made inverters cost more than imported ones, due to higher labor and manufacturing expenses. Analysts expect that gap to narrow over time as U.S. production ramps up and competition increases. There are still open questions about exactly which inverters the ban covers, especially larger equipment used in utility-scale projects, and some existing solar system owners are watching to see whether the rule could affect software updates for the inverters they already have installed. For most homeowners, this is a background shift in the solar supply chain rather than an immediate change to existing home systems.

$10 Billion Tesla Solar Factory in Texas? And $20–25 Billion TERAFAB Project in Midst of AI Bubble?

Tesla is planning a large solar cell factory in Texas, near Richmond, about 40 minutes from Houston. The project, called "Project Crystal Sun," would cost around $10.1 billion and cover the full process of making solar cells, from raw wafers to finished, tested panels, rather than just assembling parts made elsewhere. Tesla says the plant would create nearly 9,700 permanent jobs once running, with construction from 2026 to 2028 and operations starting in early 2029. Tesla is still weighing other locations, which may be a negotiating tactic to get a better deal from Texas. Separately, Tesla and SpaceX are working on an even bigger project, called TERAFAB, expected to cost two to two and a half times as much as the solar factory. It would make computer chips for AI systems, including chips meant for space-based data centers and for Tesla's Optimus robots, which are not yet on the market. Elon Musk has framed it as essential to keeping up with chip shortages tied to the broader AI boom. For homeowners, none of this changes rebates, incentives, or panel prices right now. It signals that Tesla wants to build more solar cells in the US instead of relying on imports, which could affect future panel availability or costs, but there is no timeline yet for how that might reach the retail market.

Mastering the Multi-Building Choreography of Large-Scale Data Center Campus Logistics

This piece is about how construction crews build massive data center campuses, not something that touches a typical house. It describes how builders coordinate hundreds of workers installing underground power lines, water pipes, and other utilities before a building's foundation goes in, and how they use daily meetings, drone-generated maps, and digital models to keep trades from getting in each other's way. The article also covers prefabrication, where pipe sections and electrical components are built off-site and delivered as ready-to-install modules. This cuts down on-site risk and speeds up installation. It notes that as these projects near completion, managers divide the site into zones with dedicated supervisors to make sure power, network, and cooling systems all come together at the right time for each piece of equipment. None of this involves technology, rebates, or costs relevant to a home. It is industry news about construction management practices for large commercial data centers, the kind of facility that houses servers for cloud computing and AI. There is no homeowner takeaway here, since the scale, equipment, and challenges described are specific to massive commercial builds, not residential energy upgrades.

Simplifying the sustainability certification ecosystem

This news is about how companies talk about their climate goals, not about home energy upgrades. It explains that businesses use a maze of certifications, standards, and frameworks to prove they're cutting greenhouse gas emissions, and that the terms often mean different things from one company to the next. The piece breaks this down into four parts: measuring emissions, planning a transition, taking action to cut emissions, and reporting results. It also distinguishes between frameworks (a company's own approach) and standards (widely accepted rules set by outside groups, like the GHG Protocol), with certifications acting as independent proof that a company actually followed through. Examples cited include Adidas's Climate Transition Action Plan, Nike's "Move to Zero" initiative, and a new industry effort called the Purpose Pledge from Dr. Bronner's. The article also notes a European Union rule, the Empowering Consumers Directive, that will require some companies' environmental marketing claims to be verified by an outside party before they can be advertised. None of this changes anything about home energy rebates, tax credits, or upgrade programs. It's aimed at corporate sustainability teams trying to keep their climate claims consistent and credible, not at homeowners deciding on insulation, heat pumps, or weatherization. There's no program, deadline, or dollar amount here that applies to your house.

Nextpower’s next chapter: From solar trackers to inverters and storage

Nextpower, formerly known as Nextracker, is best known for solar tracking systems used in large solar farms. The company is now expanding into two new areas: inverters, which convert solar power into electricity usable by the grid, and battery storage. It recently acquired inverter maker Zigor Corporation and its U.S. arm, Apex Power, along with battery storage company Prevalon Energy. It also plans to acquire a German company that makes solar mounting systems. On the inverter side, most current models are made in China and have grown cheaper but less durable as manufacturers pushed more electrical current through them, causing parts to wear out faster. Nextpower says its own inverters, made in the U.S., will fix this reliability problem. The timing lines up with a Trump administration ban on imports of new foreign inverter models, though inverters already sold in the U.S. are unaffected. On storage, Nextpower sees fast-growing demand for battery systems, including a newer use: as a buffer for AI data centers, which can cause sudden electricity spikes or drops that stress the grid and damage equipment. The company says batteries paired with inverters can respond fast enough to smooth out those swings. None of this changes anything for a homeowner directly — these are utility-scale technologies, not home equipment. But it reflects a bigger push to make solar, storage and grid equipment more reliable and made in the U.S., trends that can eventually affect the cost and availability of clean energy more broadly.

August eclipse to test European, U.S. grids with solar ramps

A total solar eclipse crosses from Siberia over the Arctic, Greenland, and Iceland to northern Spain and Portugal on August 12, 2026 — the first total eclipse over mainland Europe since 1999. Most of Europe will see a deep partial eclipse in the early evening, while parts of the eastern U.S. and Quebec get a smaller partial eclipse around midday. If you have solar panels, you may notice a temporary dip in output during the event, but the size of that dip depends heavily on where you live and what time the eclipse happens locally. For most of Spain, Portugal, France, and the UK, the eclipse hits late in the day when the sun is already low, so the actual loss of solar energy for the day is small, around 1%. Farther north and west, where the eclipse happens earlier relative to solar noon, the effect is bigger: Iceland could lose close to 3% of its daily sunlight, Greenland up to 6%. In the U.S., New York may lose about 2% of daily solar energy and Quebec 3-4%, since the eclipse there falls closer to midday. This matters mainly for grid operators, not individual homeowners, since it affects how much backup power and storage utilities need to bring online as solar output dips and then recovers quickly. Germany, despite losing only about 1% of its daily solar energy, is expected to see the sharpest swing of any region studied, with generation needing to ramp back up fast after the eclipse passes. Homeowners with rooftop solar likely won't need to do anything differently, but may see a brief, temporary drop in their own panel output around the eclipse's peak time in their area.

A new plan to preserve Georgia’s marshes: Give them space to migrate

In Liberty County, Georgia, local leaders are testing a way to fight coastal erosion by restoring marsh grasses instead of building walls or seawalls. The idea is that the grasses' roots hold soil in place, mimicking how marshes naturally protect the coast. These "living shorelines," built by companies like Zulu Marine, are becoming a more popular alternative to concrete barriers as sea levels rise. The bigger issue is that marshes need room to move inland as seas rise. Georgia's coast holds more than a third of the connected marsh habitat in the Southeastern U.S., and sea levels there are projected to rise one to two meters over the next 75 years. Marshes can naturally shift and survive being flooded daily, but only if they have open land to migrate into. When they hit a road, building, or other development, they simply disappear, leaving the coast more exposed to flooding. A new plan from a coalition of conservation groups, scientists, and government agencies has identified more than 56,000 acres of Georgia land where marshes are likely to migrate — land that's currently open to development. The plan isn't binding and doesn't restrict what anyone can do with their property. It's meant as a guide to help landowners and local officials think ahead about whether to build close to the water's edge or leave room for the marsh to shift over time. For homeowners along the Georgia coast, it's a signal that decisions about nearby undeveloped land could affect how well your area holds up against rising water in the coming decades.

Musk’s Terafab chip plant will run on gas, not Tesla solar

Elon Musk's SpaceX and Tesla are building Terafab, a $16.8 billion chip manufacturing plant in Grimes County, Texas, on the site of a former coal-fired power plant. Despite Tesla being a partner in the project, and despite Tesla making solar panels and batteries designed for exactly this kind of large power need, the plant will run on new natural gas power plants and large battery arrays. Tesla solar is not part of the power plan. This fits a broader pattern. Musk's xAI has been running gas turbines at its Colossus data center near Memphis, some of them unpermitted, which is now the subject of a lawsuit over pollution near homes and schools. Musk also personally bought a gas turbine company, APR Energy, for about $1 billion in July, and SpaceX has committed more than $2.8 billion to gas turbines for its data centers. Terafab's gas plants continue that trend, even though Tesla and Sunrun recently launched a large solar-and-battery program aimed at data centers, and xAI itself has bought hundreds of millions of dollars in Tesla batteries in the past. None of this changes anything about home energy programs or rebates. It's mainly a look at how one of the country's biggest new industrial power buildouts is choosing gas over solar, even when the cleaner option is made by companies its own owner controls.

Competitive transmission delivers benefits for the AI economy and customers

A group of large utilities in the MISO and SPP grid regions has asked federal regulators to suspend competitive bidding on new high-voltage transmission lines for five years, arguing that open bidding slows down projects needed to meet surging electricity demand from data centers and AI. Instead, they want incumbent utilities to be automatically assigned these projects. This is a policy fight happening at the Federal Energy Regulatory Commission (FERC), not a program homeowners sign up for. The case against the utilities' request looks strong so far. MISO, the neutral grid operator, disputes the utilities' delay claims and says one competitively bid project actually finished six months early and under budget. Independent research found competitive bidding produced roughly 30% in cost savings compared with utility-run projects, while some utility-only projects have run years behind schedule or seen costs jump over 100%. Big electricity users and consumer advocates have sided against the utilities' request. This dispute matters to homeowners indirectly: transmission costs get passed through to electric bills, and cheaper, faster-built power lines generally mean lower cost pressure over time. FERC has not ruled yet, but it has already ordered grid operators to fix separate rules about how data centers connect to the grid, suggesting regulators see that as the real bottleneck rather than the bidding process itself. There is nothing to act on now — this is a regulatory dispute to watch, not a program or rebate tied to your home.
