How To Climb a Critical Mineral Mountain? Come Together, Right Now
The U.S. Department of Energy's National Laboratory of the Rockies recently held its 2026 Partner Forum, bringing together mining companies, researchers, universities, and government officials to discuss how the country can build a stronger domestic supply of critical minerals - the raw materials used in electronics, batteries, solar panels, heat pumps, and other energy technologies. Right now, more than 80 percent of the country's critical minerals come from foreign sources, mostly China, which affects both availability and prices for the technologies homeowners might buy for energy upgrades. Speakers described several ways the U.S. could catch up: recovering minerals from waste piles, e-waste, and seawater; developing new filtering and separation technologies; finding substitute materials so products depend less on hard-to-get minerals; and using AI to speed up mineral discovery and processing. One company, USA Rare Earth, is already building a full pipeline in the U.S. - mining in Texas, developing processing methods in Colorado, and making magnets (used in things like medical devices and defense equipment) in Oklahoma. The lab also announced new partnerships with the Colorado School of Mines and the University of Utah to train more workers in this field, and is building a large new facility in Colorado where companies can test and scale up new mining and refining technologies. There's no direct action for homeowners here, but the underlying goal - a stronger, more reliable domestic supply of these minerals - could eventually mean steadier prices and availability for solar panels, batteries, heat pumps, and other electronics that depend on them.
Line 5 tunnel in Michigan clears major permitting hurdle, in blow to opposition
Michigan regulators this week approved key permits for a tunnel under the Straits of Mackinac meant to house a replacement section of the Line 5 pipeline, which carries crude oil and natural gas liquids between Wisconsin and Ontario. The state's environmental agency approved a construction permit for the lake bottomlands, and the Department of Natural Resources issued a separate permit despite acknowledging the project will harm rare plants and animals in the area. Both permits require Enbridge, the company behind the project, to take steps to limit damage, such as restoring wetlands and avoiding tree-clearing during bat season. This isn't a program homeowners can apply for or opt into, but it matters if you live near the Great Lakes region or care about the area's environment. Opponents, including tribal nations whose treaty lands the tunnel would cross, argue the project isn't needed and will lock in decades of fossil fuel use while risking cultural and burial sites. The Bay Mills Indian Community is considering a legal challenge to the permits. Enbridge still needs additional state and federal approvals, including a wastewater discharge permit and a pending Army Corps of Engineers review, before construction can start. A separate case over the pipeline's future is before the Michigan Supreme Court, with a ruling expected by the end of summer. For now, this week's approvals mark a step forward for the tunnel, but the project isn't cleared to begin building yet.
FHB Podcast Segment: A Decade of Residential Building in Review
A recent episode of the Fine Homebuilding Podcast took on a listener question: how much has home building actually changed since the show started in 2016? A listener named Miranda asked the hosts to weigh in on which tools, products, and techniques have shifted over the past decade, and which ones have stayed the same. The podcast crew discussed the topic in general terms, reflecting on a decade of developments in residential construction, but the episode does not lay out specific rebate programs, product recommendations, or dollar figures a homeowner could act on. It is more of a retrospective conversation among the hosts than a rundown of new products or incentives. If you are curious about how building practices have evolved, the episode itself is worth a listen for context, but it does not point to any new program, deadline, or upgrade you need to act on right now. Nothing here changes what is available for insulation, heat pumps, or other home efficiency work in your state.
China’s Batteries Move Beyond Capacity Scale-up: Utility-Scale Storage Could Have Shifted 23 TWh More Clean Power in 2025
China has built the world's largest fleet of grid-scale batteries, but new analysis finds much of it is underused. In December 2025 alone, China added more battery storage than the United States installed all year, and by early 2026 the country had almost 150 GW of lithium-ion battery storage. Officials just raised the 2030 target for this storage to 300 GW. But the analysis finds these batteries could have shifted 23 more terawatt-hours of clean electricity in 2025 if they'd been run harder — enough to power Singapore for five months. The gap comes down to how batteries are used. Many were built alongside wind and solar farms under a since-ended rule requiring co-located storage, and these batteries run on fairly rigid schedules, can't trade independently in power markets, and get cycled less often. Standalone batteries, dispatched directly by the grid, run far more and now make up the bulk of new installations. China has been loosening rules to let standalone storage earn revenue, but weak market pricing and price caps still limit how much money batteries can make from storing power when it's cheap and selling it back when it's needed. None of this changes anything for a homeowner's own equipment or rebates. It's a signal about where the world's biggest battery market is headed: past the initial building boom and into the harder work of making that storage actually useful to the grid, which is a preview of questions battery storage everywhere, including in the US, will eventually face.
New Partnerships With State of Alaska & University of Alaska Fairbanks Expand on Critical Minerals & Energy Innovation
The National Laboratory of the Rockies, a Department of Energy research lab, has signed two new agreements to expand energy and critical minerals research in Alaska. One is with the state of Alaska, the other with the University of Alaska Fairbanks. The lab, which has a physical campus next to the university, focuses on energy and building technology suited to extreme cold and remote locations. Past projects include studying Alaska's power grid as natural gas supplies decline, testing ways to stabilize permafrost under military buildings, and designing resilient facilities near the Alaska-Canada border. Under the university partnership, the lab gains access to campus expertise in microgrids (small, local power systems that can run independently), engineering, and critical minerals research. In exchange, the lab offers its analysis tools, including software that creates digital models of mines and power systems, and a new facility meant to help promising lab ideas grow into real, market-ready products. The agreement with the state is meant to help coordinate research and resources toward lowering energy costs and strengthening supply chains, particularly in rural and remote parts of Alaska. This is a research and policy partnership rather than a program homeowners can apply to. It does not create a new rebate or incentive. But for homeowners in Alaska, especially in rural or off-grid communities, it signals continued federal and state attention to improving energy reliability and lowering costs in extreme climates, which could shape future local energy projects and infrastructure.
New Charging Station Plan Offers More Proof-Of-Life For EVs
A California startup called Rangeway is building a new kind of EV charging station, one designed like a hospitality stop rather than a bare parking lot on the edge of a strip mall. Its lineup includes sheltered "Trailhead" stops, enclosed lounge-style "Waystation" and "Basecamp" facilities, and a boutique motel concept with off-grid charging and rooms for overnight stays. Some sites will rely on partner HyWatts, which builds a "Power-Plant-in-a-Box" combining solar power, battery storage, and hydrogen production, meant for scenic or remote spots where the electric grid can't easily support fast charging. Rangeway has picked the St. Louis, Missouri area for its first stations, teaming up with local sustainable builder LoüTeq. Missouri isn't known as an EV stronghold, and the state charges EV owners an annual fee of $150 for passenger cars, a fee set to rise over time. But St. Louis has been building up charging infrastructure and electrifying its city vehicle fleet, and the utility Ameren offers reduced electricity rates for off-peak EV charging. Specific station locations haven't been announced yet. This is mainly industry news about where charging infrastructure is headed, not a program homeowners can sign up for. It doesn't affect home energy upgrades directly, but it's a sign that EV charging is expanding into new regions, including ones that aren't typical EV markets, and that companies are competing to make public charging more comfortable and reliable rather than just adding plugs.
Siemens to unite energy businesses under new brand Omterra
Siemens Energy is retiring its brand name and combining its businesses, including Siemens Gamesa Renewable Energy, under a new name: Omterra. The change will happen gradually over the next year. The company's CEO says the switch is happening now because the license to use the Siemens name was always meant to be temporary after the business split off from Siemens AG in 2020, and the company feels ready to stand on its own. Omterra will focus mainly on wind power and power transmission, along with other renewable energy work. It's worth noting the company already sold off its utility-scale solar inverter and large-scale battery storage business to ABB last year, so this rebrand is more about corporate identity in the wind and grid side of the industry than about products tied to home solar or battery systems. For a homeowner, this is largely background news about corporate branding rather than something that changes your options for rooftop solar, battery storage, or home energy upgrades. If you already have equipment from Siemens or Siemens Gamesa, it may eventually carry the Omterra name instead, but the underlying products and any warranties tied to them aren't described as changing. There's no rebate, incentive, or program tied to this announcement that would affect a home energy project.
ARRAY Technologies is acquiring Affordable Wire Management
Solar tracker maker ARRAY Technologies is buying Affordable Wire Management (AWM), a company that makes wiring, cable protection, and electrical equipment for large solar and battery storage projects. The deal is valued at $203 million and is expected to close in 2026. ARRAY says the purchase will let it offer a more complete package of equipment for solar, battery storage, and data center projects. This follows ARRAY's acquisition last year of APA Solar Racking, a maker of ground-mount solar racking and foundations. This is a business deal between two companies that supply large, utility-scale solar and storage projects, not the kind of solar equipment used on a typical house. It does not involve residential solar panels, home batteries, or any rebate or incentive program for homeowners. For someone thinking about their own home's energy upgrades, this news does not change anything directly. It reflects a broader trend of solar and storage suppliers combining forces to serve big commercial projects, including the growing data center market, but it has no bearing on home solar installations, costs, or available incentives.
Australia Nails It Again — On Large Data Centers This Time
Australia is preparing new rules that would require large AI data centers to line up their own new clean power supply, rather than drawing on renewable energy that homes and businesses would otherwise use. Prime Minister Anthony Albanese announced the plan on July 15, saying the goal is to make data centers "net-generators, not net-users" of energy. The legislation isn't in effect yet, but it's expected to take effect in early 2027. Under the plan, large data centers would also have to pay the full cost of connecting to the grid, so those expenses don't get passed on to households or businesses through higher electricity bills. In some cases, they may also have to cut back their power use when the grid is under strain, and they'll face new water use requirements. Australia says this makes it the first country to bring these data center issues together under one national framework. This is a policy story about how Australia plans to handle the huge electricity demand from AI data centers, not something that changes any rebate or program a homeowner can apply for right now. The main point for homeowners is indirect: by making data centers cover their own power and grid costs, the policy is meant to keep this new source of demand from driving up electricity prices for everyone else. Whether anything like it comes to your state or country is still an open question, since the rule hasn't taken effect yet.
How Western Digital used AI to turbocharge collection of supplier emissions data
This story is about corporate supply chains, not home upgrades, but it shows where climate data tools are heading. Western Digital, the data storage company, used an AI tool to speed up how it collects carbon emissions data from its suppliers. Working with a startup called Sluicebox, the company built an AI email system that asks suppliers for emissions numbers, answers their questions, and turns the raw data into a standardized carbon footprint report. The results were notable: in a pilot late last year, Western Digital raised the share of its biggest suppliers reporting detailed emissions data from 30 percent to 90 percent, and cut the time needed to collect it from five or six months down to four weeks. Company staff still review the AI's output rather than letting it run unchecked, and a program manager said the goal is to free up sustainability teams to focus on quality checks and supplier relationships instead of chasing paperwork. For homeowners, this has no direct bearing on your own energy bills or rebates. It is a glimpse at how large manufacturers are using AI to track the carbon footprint of the products and components they buy and sell. If tools like this spread, it could eventually make it easier for companies to report more accurate emissions data for the goods you buy, including appliances and building materials, but that is a downstream possibility, not something available to homeowners now.
In the birthplace of the car, EVs are now king: BEVs outsell gas cars in Germany
In June, battery electric cars became the best-selling type of new car in Germany for the first time, edging out gas cars, diesels, hybrids, and plug-in hybrids individually. Battery electric vehicles (EVs powered only by a battery, not a gas engine) sold 84,057 units, just ahead of conventional hybrids at 83,315. Gasoline cars sold 60,796, diesel 33,862, and plug-in hybrids 32,212. That gives battery electric cars a 28.4 percent share of the market, the largest of any single powertrain, though gas, diesel, and hybrid sales combined still add up to more than half of all new cars sold. This is a milestone, not a takeover. Battery electric and plug-in hybrid cars together still make up only about 6 percent of all vehicles currently on German roads, since cars stay in use for years after purchase. The surge did cut the average carbon emissions of new cars sold in Germany by 13.6 percent compared to a year earlier. For a homeowner, this is mostly a signal about where the car market is heading rather than something with direct financial impact. It doesn't change any US rebate, tax credit, or charging program. If you're weighing an EV purchase and thinking about home charging, it's a reminder that battery electric cars are becoming mainstream in major markets, which can affect vehicle choice and pricing over time, but any charger installation costs or incentives still depend on what's available where you live.
EU Takes Half-hearted Step Towards Taxing International Flights
The European Commission has proposed putting a carbon price on some international flights leaving the EU for the first time, starting in 2029. The catch is that it would only apply to flights within 5,000 kilometers, so a trip from Paris to Dubai would be covered, but a flight from Paris to New York would not. Critics say this leaves nearly half of European aviation emissions untaxed. Private jets, which have avoided this carbon pricing system until now, would finally be included, and the plan also gives credit to airlines that reduce contrails, the heat-trapping vapor trails planes leave behind. The proposal also touches shipping, offering funding to help ships switch to cleaner fuels and adding more foreign ports to the carbon-pricing system to stop ships from dodging it. But large container ships would get a discount for stopping in the EU, a move critics say undercuts the point. Overall, the plan loosens the EU's carbon market by slowing the rate at which allowed pollution shrinks each year and by leaning heavily on future carbon-removal technology that has not yet been proven at scale. Environmental groups argue this weakens the incentive for airlines and shippers to actually cut emissions. For homeowners, this news is about international transport policy in Europe, not home energy programs. It does not affect heat pump rebates, weatherization funding, or other home upgrade incentives.
Thousands flee as First Nations bear the brunt of Canada’s wildfires
More than 900 wildfires are burning across Canada, and First Nations communities have been hit hardest. Thirteen First Nations are under evacuation orders, and more than 2,100 people have had to leave their homes. In Ontario alone, 193 fires are burning and seven First Nations have evacuated. The Namaygoosisagagun (Collins) First Nation, a community about 125 miles north of Thunder Bay with no road access, lost most of its homes and buildings in under an hour. Residents fled by boat with only minutes' notice, going door to door to warn neighbors since they say they got no advance warning or evacuation help from provincial or federal officials. A lawyer for the community says it's being denied disaster aid because Canada's federal government does not officially recognize it as a First Nation, even though its members are recognized as First Nations people. The community's leaders are pressing the government for emergency and rebuilding support, warning that without it, the community may not be able to rebuild at all. Ontario's regional chief has criticized bureaucratic delays and jurisdictional disputes for slowing evacuations and putting people at risk. The national Assembly of First Nations has passed emergency resolutions calling for support for Namaygoosisagagun and other affected communities, along with continued federal help as the fires keep spreading. This is a Canadian wildfire and disaster-response story, not a U.S. home energy program update, so there's nothing here that changes rebate eligibility or upgrade planning for American homeowners.
Mick Murray’s hybrid haulers move more freight with fewer fumes
This one is about mining trucks in Australia, not home energy upgrades, but here's the gist. An Australian trailer maker, Mick Murray Welding, has teamed up with mining company MLG to build "hybrid road trains" — long, multi-trailer trucks common in Australia — that use battery-powered trailers alongside a regular diesel or electric semi truck. Each trailer has its own electric drive axles and a 200 kWh battery, charged either by plugging in or by the diesel engine while empty, then topped up by regenerative braking on the loaded trip back from the mine. The idea is to cut fuel costs and emissions on heavy mining hauls while letting trucks carry more freight with less strain on the engine pulling them. The first version uses a diesel truck up front, but the companies say a fully electric version is planned once more electric heavy trucks become available. The first hybrid road train is already running at an MLG mine site, and the companies plan to sell the trailer technology to other haulage companies later this year. This is industry and mining news, not something that touches home energy use or rebates. There is no homeowner action here — it is simply a look at how heavy-duty trucking in Australia's mining sector is starting to adopt hybrid and electric technology to lower fuel costs and emissions.
Tesla launches in Latvia and Uruguay, expanding on two continents
Tesla is opening two new markets this week, in Latvia and Uruguay, though neither has much direct bearing on US homeowners. In Latvia, Tesla's first store opens August 21 in Riga, with the Model 3 and Model Y already available to order online. Pricing before the country's 21% sales tax runs from about €30,990 for the Model 3 up to €53,490 for the top Model Y. The Model 3 was already Latvia's best-selling EV even without an official Tesla presence, and the country's charging network grew 77% in the past year. In Uruguay, Tesla is now selling the Model 3 and Model Y directly, shipped from its Shanghai factory, with prices from $32,990 to $49,990 depending on the model and range. Uruguay is a small car market, but electric vehicles already make up close to 30% of new sales there, and the country's electricity grid ran on 99% renewable sources in 2024, one of the cleanest anywhere. For homeowners, the real story is bigger picture: Tesla's sales have slowed in the US, Europe, and China, so the company is chasing growth in smaller countries instead. It's a sign of how competitive the EV market has become globally, though it doesn't change pricing, incentives, or vehicle options here at home.
Watching The World’s First Flight of the NAVEE WaveFly 5X in Suzhou, China
This one is not about home energy upgrades, so there is nothing here that touches your house or your utility bills. It is a look at a new personal watercraft from a Chinese company called NAVEE, which already makes electric scooters, e-bikes, and other small electric vehicles. The new product, called the WaveFly 5X, just had its first public flight in Suzhou, China. It looks like a cross between a personal watercraft and a small plane, with four electric propellers and two wings. Instead of taking off into the air, it uses the motors and wings to skim along just 12 to 32 inches above the water, similar to a hovercraft. It can reach about 85 km an hour, travel roughly 80 km on a charge, and seats two people with a combined weight limit of 140 kg. It is still an early prototype, and it is not yet clear how many motors the final production version will have, or whether regulators will treat it as a boat, a small aircraft, or something new that needs its own licensing rules. NAVEE's website lists a price around $279,000, with a $10,000 deposit to reserve one, so for now this is aimed at luxury buyers rather than typical households. There is no word yet on when, or whether, it will become more affordable or widely available.
EcoFlow brings back Prime Day power station pricing in sale from $169, Segway Xafari e-bike $1,550 low, EGO Multi-Head, more
This roundup covers deals on portable power stations and e-bikes, not home energy upgrades — worth noting if you were expecting rebate or retrofit news. EcoFlow has brought back Prime Day pricing on its power stations, with a new sale starting at $169 and several free-gift tiers included. These battery units store electricity and can run appliances during an outage or power tools and devices away from an outlet, though this sale is about pricing, not any efficiency program. Other deals in the mix: Segway's Xafari all-terrain e-bike is at a $1,550 low, and Gotrax's R7 e-bike is at a $765 low. EGO has a bundle with a power head, 15-inch string trimmer attachment, and 5.0Ah battery back down to $319. There's also a Navee XT5 Pro off-road e-scooter near its second-lowest price and a compact Greenworks 24V chainsaw bundle. A separate Segway Max G3 e-scooter deal, at a $1,000 low, ends the next night, and an EcoFlow flash sale on dual power station bundles is also wrapping up soon. None of this touches home weatherization, heat pumps, or utility rebate programs — it's straightforward retail pricing on outdoor gear, power equipment, and backup power products. If you're tracking savings on home energy upgrades specifically, like insulation, heating and cooling systems, or electrical panel work, this particular set of deals won't apply to that.
BYD unveils its latest luxury EV with sleek fastback styling and 570 miles of range
BYD's luxury brand Denza has unveiled a new electric sedan, the Z9S, with a fastback design and a claimed range of up to 571 miles on a single charge. That figure comes from China's CLTC testing standard, which tends to produce higher numbers than the range ratings used in the US, so it would likely be lower under American testing methods. The car comes in several versions. A standard model uses one rear motor producing 429 horsepower, with another single-motor version rated at 496 horsepower. Both reportedly use the same large battery pack, just over 102 kWh. A tri-motor version listed on a Chinese car-buying site claims close to 1,200 horsepower combined. Pricing and a US release have not been announced, and the car is tied to BYD's Chinese and European markets for now. This news does not affect home energy upgrades or rebates directly, but it is worth watching if you are considering an EV alongside home electrification projects like solar, battery storage, or a heat pump. BYD has been expanding its lineup of high-range, high-performance electric vehicles, including a supercar version called the Denza Z that recently launched with pre-orders topping 1,000. None of these vehicles are currently sold in the US, so for now this is mainly a sign of where EV battery and range technology is heading globally, rather than something that changes your options today.
Volkswagen’s new ID. Polo EV secured 25,000 orders in weeks — Now, it’s even cheaper
This is a car story, not a home energy upgrade story, so it does not connect to rebates or upgrades for your house. Still, here is what happened. Volkswagen has started selling a cheaper version of its new electric car, the ID. Polo, in Europe. The company already had a pricier version with a bigger 52 kWh battery, starting around $40,000, which drew 25,000 orders in its first weeks on sale. Now there is a lower-cost model with a smaller 37 kWh battery, starting at about $29,000, with a driving range of around 207 miles. Pricier trims with more features go up to about $33,500. The cheaper model can fast-charge from 10% to 80% in about 23 minutes and comes with basic safety features like lane and side assist. Higher trims add adaptive cruise control, a rear camera, and better headlights. Volkswagen also sells a sportier, more powerful version with a larger battery and longer range, plus an electric hot-hatch variant coming this fall. None of this is available in the US, and it has nothing to do with home energy efficiency, heating, cooling, or rebates. If you are researching electric vehicles for your household, this is useful context on pricing trends in Europe, but it will not affect any home energy upgrade plans or incentives you might be looking into.
Tesla’s Offensive in South America Continues as the Brand Arrives in Uruguay, Cuts Prices in Chile
Tesla is pushing hard into South America's electric vehicle market, cutting prices and expanding into new countries. In Uruguay, Tesla just launched with a Model 3 starting at $32,990 and a Model Y at $36,490, prices low enough to undercut competing electric models from Geely and BYD. Uruguay has quickly become the leading electric vehicle market in the Americas, with electric models making up more than 40 percent of car sales in some recent months. In Chile, Tesla has quietly made deep, permanent price cuts. A Model 3 that cost roughly $42,800 in December 2025 now starts around $32,000, and the Model Y has dropped from about $47,000 to roughly $39,500, discounts of up to 25 percent. This follows a similar move in Colombia last year, where low Tesla prices helped the Model Y become the country's best-selling vehicle overall, not just among electric cars. None of this directly changes rebates or programs for U.S. homeowners, but it's a sign of how fast electric vehicle prices are falling worldwide as automakers compete for market share. If you're weighing an electric vehicle purchase alongside other home energy upgrades, like a heat pump or rooftop solar, it's a reminder that EV prices remain in flux and vary a lot by market. Tesla says it may bring similar pricing strategies to other countries, including Argentina and Brazil, as it works through excess factory capacity built up over the past two slow sales years.
Tesla finally launches a bike — but it’s not what fans wanted
This one's about cars, not home energy upgrades, but here's the gist: Tesla has launched its first bike, and it's a toddler's balance bike, not the electric bike fans have wanted for years. It sells for $225 on Tesla's website and is aimed at kids aged 2 to 5. The bike has a lightweight magnesium frame, an adjustable seat with five height settings, and Tesla branding, but no pedals or motor. Kids push it along with their feet to learn balance before moving to a pedal bike. Tesla says it fits kids with a minimum leg length of 13.7 inches and a weight limit of 77 pounds, and it comes with the tools needed to put it together. On price, Tesla lands at the high end of the balance-bike market. Many balance bikes cost $50 to $120, and a similar magnesium-frame model from another brand sells for around $73. Tesla's price is closer to premium options like the Woom 1 at $249 or the Strider 14x Sport at $220. So while Tesla fans keep hoping for an electric bike from the company, this toddler bike is what's actually available for now, priced like one of the pricier options in its category.
The Founding of YouTube A Short History
This piece is about the history of YouTube, not home energy upgrades, so there's nothing here that affects decisions about your house. No rebates, programs, deadlines, or efficiency technology are mentioned. For context, the article traces YouTube's founding to 2005, when three former PayPal employees, Chad Hurley, Steve Chen, and Jawed Karim, built a website that made it easy to upload, stream, and share video without technical know-how. Google bought the company in 2006 as it grew too large and expensive for its founders to keep running alone. None of this touches on home performance, weatherization, heat pumps, or energy rebates. If you're looking for news on energy-efficiency upgrades, air sealing, rebate programs, or heat pump incentives, this article won't help. Check back for updates specifically on those topics.
Wheel-E Podcast: New Tern HSD, 65 MPH ‘e-bike’, Segway Xaber review, more
This is about electric bikes and scooters, not home energy upgrades, so it does not connect to plans for insulation, heating, or rebates on a house. Still, here is what the news covers. A biweekly video and audio roundup discusses recent electric bike and scooter releases. Tern has redesigned its well-known HSD cargo e-bike to be sturdier and more family-friendly. Momentum released a new commuter e-bike, the Vida E+ EX, with cruise control and a throttle option. Trek introduced a fat-tire throttle e-bike called the Borrego+, aimed at riders who want a thicker-tire model. VMAX launched a lower-cost full-suspension electric scooter priced at $799. Ariel Rider put out a high-power bike, the MUDD 72V, that reaches a top speed of 65 mph, which pushes past what most people would consider a typical e-bike. The roundup also includes reviews of two other vehicles: the Infinite Machine Olto, described as an unusual take on the e-bike format, and the Segway Xaber, compared favorably to the Sur Ron off-road electric motorcycle but at a lower price. None of this touches on home insulation, heating and cooling systems, or rebate programs for houses. It is aimed at people shopping for personal electric transportation, not homeowners weighing energy upgrades.
Segway Xaber review: The mall-cop company just built a better Sur Ron for less money
This is not a home energy story, so it won't affect your utility bills or qualify for efficiency rebates. It's a review of a new electric off-road motorcycle, the Segway Xaber 300, priced at $5,299 and sold through dealers. The bike comes fully assembled and puts out 21 kW of power (about 28 horsepower), with a claimed top speed of 60 mph and a 0-50 mph time of 5.5 seconds. It weighs 187 pounds and runs on a 72V, 44Ah battery with just over 3 kWh of capacity, using Samsung automotive-grade cells. Segway says it can go up to 62 miles on the lowest power setting, though harder riding drops that to around 30-40 miles. The bike has four power modes, from a mellow setting up to a full-power "Beast Mode," plus features like traction control, regenerative braking, GPS tracking, and over-the-air software updates through a companion app. Suspension and brakes are higher-end components, including adjustable Marzocchi suspension and four-piston hydraulic brakes. The reviewer compares it favorably to established off-road electric motorcycles like the Sur Ron Ultra Bee and Talaria Sting, noting it costs less while offering more advanced electronics. Open questions include long-term durability and how well Segway's dealer network supports the bike over time, since the company is new to this kind of vehicle.
How getting a Garmin watch changed my e-biking (and my fitness lifestyle)
This one falls outside home energy upgrades, so here is a plain summary of what it actually covers. This is a personal review, not home energy news. A writer for a bike-focused site describes switching from a basic Fitbit to a Garmin Forerunner 265S smartwatch to track his e-bike rides, runs, and other workouts. He found the watch showed him that riding an e-bike, even at low power assist, still raises his heart rate enough to count as real cardio exercise, countering the common claim that e-bikes let you skip a workout. Beyond fitness data, he covers the watch's other features: automatic upload to Strava for comparing rides with friends, route maps, sleep tracking, daily step streaks, recovery-time recommendations after hard workouts, and general smartwatch functions like phone-finding and notifications. He notes the battery lasts roughly a week with daily use, up to ten days if stretched. Downsides include a proprietary charging cable (he recommends buying spare adapters), a $449 price tag for this mid-tier model, and a menu system so packed with metrics and features that it can feel like information overload. None of this relates to home energy efficiency, rebates, or upgrades. It is a consumer gadget review about fitness tracking and personal exercise habits, with no relevance to insulation, heating systems, weatherization, or utility programs. If you're researching ways to cut energy costs or plan retrofits for your house, this article won't have anything useful for that project.
Getting to Know Your 2026 Tesla
This one is outside what Retrofit Relay covers. The site helps homeowners with home energy upgrades — things like heat pumps, insulation, air sealing, and rebate programs — and this article is a personal review of a 2026 Tesla's control layout and driving features, which is a vehicle rather than a home upgrade. If it helps, I can flag that Tesla and other EVs sometimes come up on this site in the context of home charging setups, electric panel upgrades needed for a home charger, or rebates that bundle EV purchases with home electrification incentives. But the article itself is about steering wheel controls, seat adjustments, self-driving software subscriptions, and trim-level differences between Tesla models, none of which affect a homeowner's house or energy costs directly. If you'd like, I can summarize a different article about home energy upgrades, or let you know if there's a home-charging or panel-upgrade angle you'd like covered instead.
Podcast: TSLA shareholders wake up, Xpeng targets EU, VW goes cheaper, and more
This is a roundup of car and energy industry news, not directly about home upgrades, but a couple of items connect to household energy decisions. CATL, a major battery maker, has introduced a sodium-ion battery rated for 30 years and 15,000 charge cycles, aimed at grid storage. That matters for homeowners because grid-scale storage like this helps utilities handle more solar and wind power, which can affect electricity reliability and rates over time, though this particular battery is for utility systems rather than home batteries. The rest covers the electric vehicle market: Tesla shareholders are pressing the company on missed goals, and a study found Tesla's LFP (lithium iron phosphate) battery holds its charge better over time than its nickel-based version, information relevant if you're weighing EV batteries for long-term durability. California rolled out a new $3,500 EV rebate that favors Rivian and Lucid models over Tesla. Volkswagen and Xpeng are pushing cheaper EVs, with Volkswagen's ID. Polo drawing 25,000 orders and getting a price cut, while Honda is discontinuing its only EV sold in the US. None of this changes anything about home energy rebates or upgrade programs. If you're considering an EV alongside home electrification work like a heat pump or panel upgrade, it's worth knowing prices and rebates in this market are shifting quickly, but the news here is about vehicles and batteries, not home efficiency programs.
BMW i3 Touring caught for the first time, and that wagon rear is hard to miss
This is a car news item, not an energy-efficiency or home upgrade story, so it does not affect your house or any rebate program. Briefly, for context: BMW's electric i3 wagon, called the i3 Touring, was spotted in public for the first time, still wearing camouflage. It follows the i3 sedan, which went on sale in June as BMW's second "Neue Klasse" model after the iX3 SUV. In Germany the sedan starts around €65,900 ($75,500), with a First Edition version at €75,340 ($86,400). UK pricing starts at £53,005 ($70,000) for the standard model, arriving this autumn. The sedan has a large 108.7 kWh battery and a rated range up to 566 miles in Europe's test cycle, or about 440 miles under the US EPA rating. It can add roughly 250 miles of range in about 10 minutes on a fast charger, and US versions will use BMW's NACS charging port, the same connector Tesla uses. The Touring wagon is expected to offer more cargo and passenger space than the sedan, but likely with somewhat less range and a higher price. None of this involves home electricity use, insulation, heating, or rebate programs. It is simply an update on an upcoming electric car model. Production is set to start this summer at BMW's Munich plant, with deliveries expected this fall, and more details on the wagon version are expected soon.
Toyota is offering $3,000 if you trade in your old EV for its new electric SUV
Toyota is offering $3,000 off its new electric SUV, the bZ, if you trade in an older EV. In California, the deal applies to 2020-2023 model year Tesla Model Y or Model 3, Hyundai IONIQ 5, Ford Mustang Mach-E, Volkswagen ID.4, Kia EV6, or Nissan Leaf. Toyota says similar offers exist in other regions, though terms may differ, so it's worth checking what's available where you live. Other current deals include 0% financing for 72 months and leases starting around $379 a month. These offers run through August 3, 2026. The 2026 bZ has become one of the best-selling EVs in the country, and the upgrades explain why. Range now reaches up to 314 miles, up 25% from the older bZ4X, and the car has a built-in NACS port, so it can plug into Tesla Superchargers without an adapter. Fast charging can take the battery from 10% to 80% in about 30 minutes, and a new preconditioning feature warms the battery ahead of charging, addressing complaints about slow charging in cold weather. The interior gets a larger 14-inch touchscreen, along with heated seats and standard safety features. Pricing starts at $34,900 for the base model with 236 miles of range, and $37,900 gets you the longer 314-mile version. If you already own one of the eligible older EVs and live where Toyota's trade-in offer applies, it could be worth a look, especially alongside any state or utility rebates you may also qualify for.
New Jersey law will let data centers pay for home energy upgrades
New Jersey has a new law that could pay for home energy upgrades using data center money. Gov. Mikie Sherrill signed the Data Center Fair Share Act, which lets data centers fund household improvements like heat pump heating and water heating systems, rooftop solar, and batteries. In exchange for covering these costs, data centers get faster approval to connect to the power grid. The idea is that reducing home energy use elsewhere frees up capacity for the data centers, since they've been driving up electricity prices in the regional grid that covers New Jersey and much of the Midwest and mid-Atlantic. For homeowners, this could mean lower electricity bills, potentially by hundreds or thousands of dollars a year, if you're enrolled in one of these programs. Rewiring America, a nonprofit that pushed for this approach, estimates that of New Jersey's roughly 2 million single-family homes, about 85,000 have older electric-resistance heating and 422,000 have electric-resistance water heaters — prime candidates for a heat pump swap. But the group says any household could potentially benefit from solar or battery storage too. Nothing happens immediately. New Jersey's utility regulator has a year to set the rules, and utilities then have 180 days to submit their own program proposals. A policy analyst involved in drafting the bill estimates enrolled households could start receiving funded upgrades as soon as mid-2028. Other states, including New York, California, and Pennsylvania, are exploring similar ideas, so it's worth watching whether something similar comes to your state.
Retail electric rate increases outpace inflation with prices set to rise higher
Electric rates are climbing faster than inflation, and a new analysis suggests more increases are coming. From 2024 to 2025, U.S. electric rates rose 2.6% after adjusting for inflation. Since 2019, residential rates are up 33% in nominal terms. Utilities requested $18 billion in rate hikes in 2025, and regulators approved 64% of the dollar value of these requests between 2021 and 2025 — a pattern that points toward continued price pressure. The increases are not even across the country. California, Maine, New York, New Jersey, Massachusetts, Maryland, Connecticut and Rhode Island have seen the steepest inflation-adjusted rate increases since 2019. In California, much of the cost comes from utilities spending on wildfire-related infrastructure work. In Maine, storm repairs, a fast-growing community solar program and higher natural gas prices all pushed rates up. Some places saw relief instead: Hawaii ratepayers got a break from updated fuel contracts, and North Carolina benefited from federal tax credits for nuclear power plants. Despite the increases, electric bills as a share of income remain near historic lows nationally, and burdens actually fell in 23 states since 2019. But that trend has reversed somewhat since 2023, especially for lower-income households — one in three households earning under $50,000 a year now spends at least 5% of its income on electricity. Since rates and trends vary so much by state, it's worth checking what is happening with rates and any assistance programs where you live.
Refrigerant Leaks at Spring Startup: Identifying and Preventing Common Issues
Spring is when many air conditioning problems show up as refrigerant leaks, often found during a routine tune-up. These leaks don't usually cause the system to stop working right away, so a homeowner may not notice anything until performance gradually declines or internal parts get damaged. In older systems, five to ten years old, the most common leak spot is the indoor evaporator coil, the part that cools the air inside your air handler. It corrodes over time from a reaction between moisture and airborne chemicals released by building materials like flooring, carpet, and paint. Newer homes are built tighter to save energy, which means these chemicals can't easily vent outside. Instead they get pulled into the HVAC system and speed up corrosion on the coil, eventually creating tiny pinhole leaks. If a leak turns up in a newer system, the more likely cause is how it was installed, particularly the soldering (called brazing) of the copper refrigerant lines. Skipping steps like flowing nitrogen gas through the lines during brazing, not cleaning the copper thoroughly, or not heating it properly can leave weak joints that fail months or years later. One expert noted that a thorough pressure test with nitrogen gas right after installation catches most of these problems before they become a lasting issue. If your system is in that five-to-ten-year range, or was recently installed, a leak found early is far easier to deal with than one left to damage the equipment.
Refrigerant Leaks at Startup: Identifying and Preventing Common Issues
Refrigerant leaks are one of those problems that build quietly. Your air conditioner or heat pump won't suddenly stop working, but a small leak can slowly reduce cooling performance and damage internal parts over time. Industry experts say leaks are usually found in one of two spots: older systems, or newly installed ones. In systems five to ten years old, the leak is almost always at the indoor evaporator coil (the indoor unit that absorbs heat from your home's air). Corrosion, caused by moisture and airborne chemicals from things like flooring, carpet, and paint, slowly eats pinholes into the copper. Newer, tightly sealed homes actually make this worse, because those chemicals can't easily escape and instead get pulled into the system. This kind of leak is hard to prevent, since it's tied to how the coil interacts with your home's air over the years. Leaks in newer systems usually trace back to installation mistakes, particularly in how copper lines were joined together (a process called brazing, which uses heat and filler metal to seal pipe connections). Skipping steps like flowing nitrogen through the lines to prevent oxidation, not cleaning the copper before joining it, or not heating it properly can all leave a weak joint that eventually fails. One expert noted that a thorough pressure test with nitrogen gas right after installation catches most of these problems before they ever become a service call. If you're getting new equipment installed or major components replaced, it's worth knowing that this kind of testing exists and is meant to catch leaks before they show up as a slow loss of cooling down the road.
Extreme Heat, Extreme Costs: How Danger Season Exacerbates the Affordability Crisis
This summer's heat waves and storms have been a reminder of how much homes now depend on electricity to stay safe, not just comfortable. Air conditioners, fans, and refrigerators for medication all need power, and for older adults, young children, and people with chronic illness, cooling can be a matter of health, not just comfort. But cooling is getting more expensive. Since 2020, average household electricity spending during the May-to-October stretch has risen more than 30 percent, driven by higher electricity demand, rising retail prices, and grid infrastructure costs. At the same time, homes need more cooling than they used to, based on 50 years of federal weather data tracking how much cooling buildings require each season. These rising costs land hardest on lower-income households, which already spend a much bigger share of their income on energy bills. Census survey data found that more than a quarter of households earning under $25,000 a year kept their homes at temperatures they considered unsafe or unhealthy, and lower-income households were far more likely to cut spending on food or medicine to cover energy bills. Newer federal survey data also show rising rates of utility disconnection notices and inability to adequately heat or cool the home compared with just a few years earlier. Steps like weatherization (sealing and insulating a home to cut energy use), utility bill assistance programs, and stronger protections against disconnection can help households manage these costs. Programs vary by state, so it's worth checking what assistance is available where you live.
Five trends that are shaping the new market for distributed capacity
Home batteries and rooftop solar are becoming part of a bigger shift in how the power grid works, and it could change what's available to homeowners. Rising electricity demand, driven partly by AI data centers, is pushing utilities and companies to rely more on networks of small home-based devices, called virtual power plants, instead of building new power plants. These setups link together things like home batteries and electric vehicle chargers so a utility can draw on them when the grid needs extra power. Several companies are striking deals to build these networks. Tesla, Sunrun, and Renew Home are combining forces to offer a large pool of flexible home power capacity to utilities and large tech companies. In Texas, Octopus Energy and Lunar Energy are offering homeowners a discounted home battery paired with fixed electricity pricing for three years, while Base Power is expanding battery programs with a utility co-op there and has started signing up customers in Illinois. Falling battery prices are a big reason this is happening: costs have dropped sharply over the past three decades, making it cheaper to install and manage batteries as grid resources. States are also getting involved, often citing the goal of lowering utility bills. New Jersey, Virginia, California, and New York have all taken recent steps, from executive orders to new laws, to encourage or fund these home-battery and demand-management programs. Rules and incentives still vary widely by state, so what's on offer where you live depends on local policy and utility programs.
Why a cash trapdoor is pulling clean energy developers into bankruptcy
Several major solar and clean-energy companies have recently filed for Chapter 11 bankruptcy, including SunPower, Sunnova, Pine Gate Renewables, Mosaic, and PosiGen. Industry lawyers discussing the wave of filings point to a pattern: many solar developers are financially weaker than they appear, and problems can surface suddenly after long periods of borrowing against future income. Part of the issue is neglect. Some developers focus on building projects but do a poor job maintaining them once they're running, sometimes losing track of basic finances and site conditions. One example described a solar site where a lender was told the project was doing fine financially, only to find the site literally flooded, with water inches from destroying the equipment. Financial trouble also gets worse because of complicated loan structures. When companies get desperate, they can bring in new financing that undercuts existing lenders' rights, or mix cash from different projects together instead of keeping it separate as originally promised, making it hard to sort out who owns what when things fall apart. For a homeowner, none of this directly changes your rooftop system, your rebate eligibility, or your utility bill. But it's a signal that some large solar and storage companies are under financial stress, which is worth keeping in mind if you're evaluating a company's stability before signing a long-term contract, lease, or loan tied to a solar installer or financing provider. The report notes that some buyers are already purchasing distressed solar assets out of bankruptcy at a discount, aiming to fix maintenance problems and make them profitable again.
Bill McKibben: “We live on a planet where the cheapest way to make power is to point a sheet of glass at the sun.”
Solar and battery power are now the cheapest way to generate electricity, and the numbers are starting to show it in daily life, not just in theory. In Australia, so much midday solar floods the grid that some utilities offer free electricity during sunny afternoon hours. In California, clean energy regularly covers more than all of the state's demand during parts of the day, with batteries storing the extra solar power to use after sunset. That shift has helped California cut its natural gas use for electricity by 60% over two years. This is happening even as federal support for clean energy, including parts of the Inflation Reduction Act, faces cuts. But the building boom hasn't slowed. Developers expect to add 86 gigawatts of new power capacity in 2026, the biggest single-year jump in two decades, with solar and battery storage making up nearly 80% of it. Natural gas, by comparison, accounts for a small fraction of new capacity. Notably, this isn't just a blue-state trend: more than two-thirds of the solar capacity installed in 2025 was built in states that voted for Trump, with Texas leading the country. For homeowners, the takeaway is less about any single program and more about the bigger picture: solar and battery technology have gotten cheap enough that they're spreading regardless of which way political winds blow. That doesn't change what's available to you directly, but it does suggest the cost trends behind rooftop solar, home batteries, and electrification tools like heat pumps are moving in one direction.
What data center developers need to know about FERC’s large load directives
The Federal Energy Regulatory Commission (FERC), the agency that oversees the interstate power grid, took action on June 18 aimed at the huge amount of electricity data centers are demanding. It issued orders to six regional grid operators — PJM, MISO, SPP, CAISO, NYISO and ISO-NE — saying their current rules don't clearly handle "large loads," defined as facilities pulling more than 50 megawatts of power. Each operator now has 60 days to defend its rules or propose changes, plus 30 days to report on whether enough power plants exist to serve this new demand. This matters to homeowners because data centers have been blamed for a good share of rising electric bills in several states, as utilities build new power lines and plants to serve them. One piece of FERC's order pushes for cost transparency, meaning data centers would have to cover the cost of their own grid upgrades instead of those costs landing on everyone else's bill. FERC is also encouraging data centers to use on-site backup power and to accept flexible service, cutting their electricity use at peak times rather than always drawing full power. None of this changes anyone's bill right away. It's the start of a regulatory process, not a final rule, and grid operators still have to respond, negotiate and finalize new tariffs. But it is the first coordinated attempt to make data centers pay their own way and ease pressure on the grid that everyone's home also depends on.
Smart Energy Management Research Could Unlock Grid Flexibility & Cost Savings
More electric cars, appliances, and home batteries are putting new strain on local power grids, and utilities are looking for ways to handle that growth without expensive equipment upgrades. Researchers at a national lab worked with Xcel Energy, which serves electric customers in Colorado, Minnesota, Wisconsin, Michigan, North Dakota, South Dakota, Texas, and New Mexico, to study "smart energy management" — shifting when homes draw power, rather than just adding bigger equipment, to avoid overloading transformers and lines. In one test area, this approach let more than 94% of home vehicle charging sessions happen fully as needed, without increasing equipment overloads, by taking advantage of the long overnight hours when cars usually sit plugged in. Out of this work came a new free tool called EVI-DiST, which any utility can use to study its own grid and figure out where smart charging or other load-shifting strategies could delay or avoid the need for infrastructure upgrades. The tool was built with electric vehicle charging in mind, but the researchers say it applies broadly to other home energy equipment as well, such as batteries or solar systems. For homeowners, this doesn't change anything immediately, but it points to where utility programs may be headed: more options tied to time-of-use rates or automated charging schedules that reward using electricity, especially for EV charging, during off-peak hours like overnight. Whether and when such programs show up depends on your own utility, so it is worth watching for updates from the company that serves your area.
Mike Rowe Awards $3 Million in Skilled Trades Scholarships as HVAC Labor Shortage Continues
TV host Mike Rowe's mikeroweWORKS Foundation has awarded more than $3 million in scholarships this year for people training in skilled trades, including HVAC (heating, ventilation, and air conditioning) work. The foundation gave out 322 scholarships in the first four rounds of 2026, ranging from $500 to $34,000, covering 23 trades across 45 states. The foundation's goal is to reach $10 million in scholarships this year, and Rowe has said the money comes with strict application requirements rather than easy handouts. The push comes as the trades face a widening worker shortage. One industry estimate cited in the news points to nearly 192,000 unfilled HVAC technician jobs expected by 2030, along with large shortfalls in construction, carpentry, electrical work, plumbing, welding, and mechanic jobs. To help address this, the Department of War recently gave Rowe's foundation a $10 million donation to launch a new effort called the Build Freedom Initiative, aimed at training more young Americans for hands-on trade careers, including work tied to defense manufacturing and repair. For homeowners, this news doesn't change any rebate or upgrade program, but it's a sign of where the industry is headed. A shortage of trained HVAC technicians can mean longer waits for installation or repair appointments, especially as more households move toward heat pumps and other efficiency upgrades. Efforts like this scholarship program are aimed at growing that workforce over time, though the near-term effect on availability of local contractors will vary by area.
More chief sustainability officers are taking on risk management, survey finds
This is corporate news about how big companies manage sustainability staff, not something that affects home energy upgrades or rebates. A new survey of chief sustainability officers (executives who oversee environmental and climate strategy at large public companies) found that most now see their main job as managing risk, not just cutting costs. Of the 69 executives surveyed, 62 percent said identifying regulatory, supply chain and climate risks is how they add the most value to their company, ahead of energy and waste savings (52 percent) and customer-related initiatives (38 percent). The survey, from recruiting firm Weinreb Group, also found that customer pressure, regulation and investor demands are the top forces shaping corporate sustainability plans, while economic uncertainty and regulatory requirements are the biggest challenges these executives face. About 42 percent said their responsibilities have grown over the past year, and a similar share said their companies are now hiring sustainability specialists into other departments, not just central teams. Reporting lines are shifting too: only 14 percent of these executives now report directly to their CEO, down from 33 percent 18 months ago, with more reporting instead to legal departments. None of this changes what rebates or incentives are available for home upgrades. It simply shows that large companies are treating sustainability more as a risk-management function tied to regulation and market pressure, which may eventually shape corporate products and policies but has no direct bearing on homeowners right now.
Massachusetts lawmakers try new way to kill ‘zombie’ wood power plant
Massachusetts lawmakers are trying a new tactic to stop a long-fought wood-burning power plant proposed for Springfield. Both the state House and Senate have passed energy bills containing identical language that would stop electricity from wood-burning plants from counting toward the clean energy standards that the state's 41 municipal utilities must meet. That matters because those municipal utilities were seen as a likely customer base for the plant. Without that market, backers of the effort hope the project becomes financially unworkable. The plant, proposed by developer Palmer Renewable Energy back in 2008, would burn wood waste in Springfield, a city already dealing with heavy air pollution and high asthma rates. Burning wood for power releases more carbon dioxide than coal and far more than natural gas, plus particulate matter linked to breathing and heart problems. The project has been declared dead more than once, only to be revived through court rulings on old permits. A case over one of those approvals is set for a hearing in December, and it's unclear whether the developer would also need a new local permit from Springfield before building. This is a state policy fight, not something that changes any programs for homeowners right now. If you don't live near Springfield, it has no direct effect on your home or upgrades you might be planning. For residents near the proposed site, it's a sign the plant may finally be losing its financial footing, though the developer has not said whether it has another way to fund the project.
Indiana regulators investigate utility ROEs, ‘trackers’ in affordability review
Indiana's utility regulator has opened investigations into how much profit power companies are allowed to earn on their investments (called return on equity, or ROE) and their use of "trackers," which let utilities raise bills between formal rate cases to cover certain costs right away. The move follows a broader affordability review the commission released this week, which also recommends doubling ratepayer assistance programs and expanding energy efficiency efforts. Utilities that could be affected include AES, American Electric Power, CenterPoint Energy, Duke Energy and NiSource. This comes after Indiana Gov. Mike Braun pushed for lower utility rates, replaced the commission's chairman, and called for a rehearing of a recent AES rate increase. The affordability report suggests that under a new law shifting utilities to multi-year rate plans, companies face less financial risk and so may not need such high guaranteed profits or the same tracker mechanisms. One utility's Indiana subsidiary, for example, is earning a return well above its officially authorized rate. The commission also wants the state legislature to consider dropping the 7% sales tax on utility bills and giving regulators more power over utility mergers. For homeowners, none of this changes anything immediately, but it is part of a push that could shape how much utilities are allowed to charge and how quickly they can pass along costs. If regulators and lawmakers act on these recommendations, it could eventually affect electric rates and available bill assistance programs in the state.
Choosing a Front Door: The Basics and Beyond
A front door does more than look good. It seals out weather, contributes to home security, and affects your energy bills more than most people realize. A recent guide breaks down what actually matters when picking one, whether you're replacing an old door or building new. Material is the first big choice. Wood offers the most character but needs regular refinishing and has the weakest energy performance unless it has an insulated core. Steel is budget-friendly and durable but dents easily and isn't great near the coast, where salt air corrodes scratched paint. Fiberglass splits the difference: low maintenance, resistant to dents and rot, and available with wood-grain texturing, making it a popular pick for most homes. Glass panels brighten an entry but are always less efficient than the solid part of the door, so it's worth thinking about which direction your door faces — a west-facing glass door can make an entryway uncomfortably hot in summer. More importantly, most of a door's real energy performance comes not from the slab itself but from the weatherstripping, sweep, and sill around its edges. Worn or cheap weatherstripping lets in drafts and moisture no matter how good the door itself is, so if you're shopping for a new door, it's worth checking whether these parts are replaceable. Doors also carry a U-factor rating (lower is better), which building codes require to meet certain minimums depending on your climate zone — a detail worth checking if you're doing a replacement. Upgraded hardware, like ball-bearing hinges, adjustable hinges, and multipoint locks, can add real durability and security, particularly for heavier wood or taller doors.
From Mine to Megawatt: How NLR Is Securing Critical Mineral Supply Chains for the Power Grid
A researcher at the National Laboratory of the Rockies described a modeling tool that tracks the materials behind the power grid, from mined metals to finished equipment like transformers, circuit breakers, and transmission lines. The tool, called the RING Model, follows materials such as copper, cobalt, and lithium through every stage, from extraction to manufacturing, so researchers can spot bottlenecks and see how a shortage of one material might ripple across different technologies and industries. One material getting closer attention is copper, which shows up in nearly every electrical product, including the wiring and equipment that make up the grid. Looked at one technology at a time, copper supply seems fine. But when researchers add up demand across batteries, transformers, and other grid equipment together, the copper industry is projecting a possible global shortfall of 30 percent by 2035. The lab is also studying how local support, permitting timelines, and the pace of new mining projects affect how quickly the country can supply the materials a growing grid will need. None of this changes what a homeowner needs to do right now. It is a look at the supply chain behind the equipment utilities use to keep the lights on and expand grid capacity, not a program or rebate tied to any individual house. But it is worth knowing about, since material shortages and bottlenecks in things like transformers and transmission lines can eventually affect how fast utilities can connect new solar, batteries, or electrical upgrades at the neighborhood level.
Renewables remain cheapest, but their LCOE is rising: Lazard
A new report from the financial firm Lazard looks at the cost of building and running different types of power plants over their lifetime, a measure called levelized cost of electricity, or LCOE. The finding: costs are rising across the board, driven by higher borrowing costs, tariffs, and pricier equipment. But solar and wind still come out cheaper than new gas or nuclear plants. Utility-scale solar costs between $40 and $98 per megawatt-hour, and onshore wind between $37 and $99, according to the report. That compares with $51 to $129 for gas plants built to run often, and $175 to $255 for nuclear. Federal tax credits can push solar's low end down to $16. The gap between the cheapest and priciest wind and solar projects is widening, which the report says reflects some developers handling rising costs better than others. This is mostly a utility-scale story about power plants feeding the grid, not home equipment. But it matters indirectly: if your electricity comes from a utility, the mix of power plants it builds affects your rates over time. The report also notes that battery storage costs went up this year, partly because tariffs have limited access to cheap imported batteries, which could matter if you're considering home battery storage down the line. None of this changes what federal or state rebate programs offer homeowners for insulation, heat pumps, or other upgrades.
30 Years Off the Grid
A couple in the Tucson Mountains has lived off the grid for over 30 years, and their updated account offers a real-world look at how solar power, batteries, and water systems have improved since the 1980s. Their house uses thick insulation, concrete block walls, and steel roll-up shutters to manage desert heat, along with a shaded courtyard and careful window placement to limit afternoon sun. These passive design choices have needed no maintenance over three decades. On the power side, they started with a 5kW solar array and lead-acid batteries that had to be hand-watered and couldn't be drained past 50 percent. They've since upgraded twice, and their current 13.5kW solar array with a 50kWh lithium battery system runs the house, including efficient ductless heat pumps (called minisplits) for heating and cooling, without the buzzing power quality or generator backup they once needed. Panel costs have dropped sharply, from $25 a watt in 1988 to $0.40 a watt for their most recent addition. Water has been the bigger challenge, since their well never found water. They still haul in water regularly, but switching from evaporative cooling to minisplits cut their weekly water use roughly in half. They also added a hot-water recirculation system, which sends cooled water in the pipes back to the heater instead of down the drain, a low-cost upgrade that works in any home, not just an off-grid one. They dropped solar water heating altogether, finding modern propane tankless and heat-pump water heaters more practical.
Honda is officially pulling the plug on its only EV in the US
Honda is discontinuing the Prologue, its only electric vehicle sold in the US. The company confirmed sales will end later this year after the 2026 model year wraps up. Honda says current Prologue owners will keep getting service, parts, and warranty coverage through its dealer network, so owning one won't leave you stranded. The Prologue had actually been a strong seller, ranking among the top 10 EVs in America, but it's built on General Motors' Ultium platform rather than a Honda-designed one, and GM is moving away from that platform. Honda also scrapped its own next-generation EVs earlier this year, meaning it will soon have no electric vehicles built or sold in the US at all. Instead, the company is shifting toward a new lineup of hybrids, with 15 new hybrid models planned worldwide by 2030, including larger hybrids for North America. For anyone shopping for an EV, this narrows the field, though Honda is offering closeout lease deals on remaining Prologue models, reportedly starting around $279 a month, for those interested in one before it disappears from showrooms. If you already own or lease a Prologue, nothing changes immediately for maintenance and repairs. But if you were hoping Honda would offer more electric options down the road, that push is on hold while the company bets on hybrids instead.
Report: How California utilities value advanced transmission tech
California's three big utilities, ordered by a 2024 state law to study grid upgrade technology, found 85 possible near-term projects that could squeeze more power through existing transmission lines without building new ones. The tools include dynamic line rating, which uses sensors and software to let a line carry more power when weather conditions allow, and advanced reconductoring, which swaps old wires for higher-capacity ones. Utilities identified 23 lines as candidates for the first approach and 62 for the second. Most of that potential sits in Southern California Edison's territory, which covers central California down the southern coast. SCE searched broadly across its whole system for good candidates and found value in upgrading nine of eleven lines it studied, some in as little as one or two years. Pacific Gas and Electric and San Diego Gas and Electric took a narrower approach, checking only a handful of lines already flagged for other reliability work, and found fewer opportunities as a result. None of this guarantees the projects will get built. Analysts who reviewed the reports say utilities are still using old planning habits and cautious regulatory approaches that slow adoption, even though the technology itself is proven and, in some cases, has been used elsewhere for over a decade. For homeowners, faster and cheaper transmission upgrades could eventually help hold down electricity costs and improve reliability, particularly as California's power demand grows from data centers and clean energy goals. But that depends on whether utilities and regulators actually expand these programs beyond the pilot projects described in this first round of reports.
Data, Data Everywhere And Not A Byte To Think
The data centers powering artificial intelligence are drawing pushback over their strain on electric grids and water supplies, and the effects could reach your utility bill. These facilities use enormous amounts of electricity to run and cool their servers, which can push up costs for everyone else on the grid. New Jersey just passed a law requiring large data centers to pay for their own grid upgrades and cover the cost if a project falls through, so those expenses don't land on regular ratepayers. New York went further, with Governor Hochul signing a one-year pause on approving new large-scale data centers (those using 50 megawatts or more) while the state figures out how to evaluate their environmental impact. At the federal level, Senator Ed Markey has proposed rules that would require data center developers to get certified that their projects won't harm the public interest, with regulators weighing effects on air and water quality, energy costs, and grid reliability before construction starts. None of this is law yet, but it signals growing attention to how AI's infrastructure boom affects household electric rates and local water supplies. For homeowners, the direct takeaway is limited for now: no new rebates or upgrade programs came out of this. But if you live in a state where a data center is proposed or being built, it's worth watching whether your state adopts similar cost-protection rules, since these facilities can influence electricity rates in the surrounding area.
