Data centers use more power in the US than in any other country
The U.S. now uses more electricity for data centers than any other country, including China. Last year, American data centers consumed nearly 313 terawatt-hours of power, about 40% of all data center demand worldwide, according to a new report from the Energy Institute. That's more electricity than Australia, Italy, Spain, or the UK generate for their entire economies. The surge is being driven by tech companies racing to build out facilities for artificial intelligence, and demand has grown 59% globally since 2022, the year ChatGPT launched. This growth isn't slowing down. Some forecasts suggest U.S. data center power demand could nearly triple by 2030, though estimates vary and some planned projects may never get built or could face delays. For homeowners, this matters because of where that power comes from and who pays for it. Consumer advocates worry that without stronger oversight, the cost of upgrading the grid to handle data center demand could land on ordinary electricity customers, not just tech companies. There's also concern that utilities will turn to natural gas to meet this new demand quickly, which would mean more carbon emissions and air pollution in the areas near new gas plants. As this plays out, it's worth watching how your own utility and state regulators handle the costs and energy sources tied to data center growth, since that could show up in future electric bills or in the mix of power feeding your home.
The DC metro area is getting its first en-route electric bus chargers
Alexandria, Virginia is building the DC area's first en-route chargers for electric buses. Construction has started on two overhead pantograph chargers at the West Alexandria Transit Center, near the former Landmark Mall site, for DASH (Alexandria Transit). A pantograph charger is an overhead arm that lowers to connect with a receptor on a bus roof, delivering fast DC power. These two chargers will each provide up to 360 kW, letting buses top up quickly while out on their routes instead of only at the depot, so they can run longer routes with fewer breaks. The project is funded with more than $1 million from the federal Fiscal Year 2024 Consolidated Appropriations Act, backed by Congressman Don Beyer and the region's federal delegation. ABM's Technical Solutions division is supplying the charging equipment, and DASH says it worked with bus manufacturers to make sure the system works with both its current electric buses and ones it buys later. Construction is expected to finish in 2027. This is part of Alexandria's push, dating to a 2019 city goal, toward an all zero-emission bus fleet. DASH already runs 16 battery-electric buses, with 20 more funded and being purchased. The agency is also expanding its bus depot, started in late 2025, to fit up to 30 more electric buses and infrastructure for as many as 24 additional pantograph chargers. This news is about public transit infrastructure rather than home energy upgrades, but it shows the pace of electrification spreading into local transportation systems around the region.
Kia converts its electric van into an off-grid mobile simulator rig with a 55″ screen
This is car news, not a home energy story, but one detail is worth noting for homeowners thinking about electric vehicles and backup power. Kia turned one of its electric vans, the PV5, into a mobile racing simulator with gaming seats and a 55-inch screen, built to raise money for a men's mental health charity at the Goodwood Festival of Speed in England, running July 9 to 12, 2026. What makes this relevant beyond the novelty is how the simulator gets its power. The setup runs entirely off the van's battery using vehicle-to-load (V2L), a feature that lets an electric vehicle send power out to run other equipment, essentially working like a portable generator. Kia says the simulator used just 1 percent of the van's charge for every two hours of operation, which gives a sense of how much spare capacity these larger EV batteries can have for running gear beyond just driving. For homeowners, the takeaway isn't about this specific van but about the technology itself. Vehicle-to-load and related vehicle-to-home features are increasingly built into new electric vehicles, and some can power appliances or even help back up a house during an outage, depending on the model and setup. If you're considering an EV purchase alongside home energy upgrades, it's worth checking whether a given model offers this kind of power-sharing capability.
Tesla caps employee AI spending at $200/week except for Grok
This is corporate news about Tesla's internal AI policies, not a home energy story. Tesla told employees it's capping AI spending at $200 a week starting July 6, after software engineers had been running up bills of thousands of dollars a week using AI tools. The catch is that the cap doesn't apply to beta versions of tools made by xAI, Elon Musk's other AI company, which steers heavy users toward Grok and Composer rather than competing products. Tesla had spent the prior six months pushing employees to use AI more, even ranking workers by usage on internal dashboards, before reversing course once costs got out of hand. Similar spending caps have shown up recently at Uber, Meta, Amazon, and Walmart as companies confront the real cost of AI tools billed by usage. None of this changes anything about home energy upgrades, rebates, or equipment costs. It's a look at how one company is managing its own software expenses, tied to Tesla's broader bet that AI will power products like its Robotaxi service and Optimus robot. The article does include an unrelated sponsor note about rooftop solar, pointing out that solar can lock in stable electricity costs as rates rise, with financing options like leases or power purchase agreements that require no upfront payment. That's a separate item from the AI story and worth keeping in mind only if you're already weighing solar for your own home.
Electrek American Solar Challenge 2026: About the race, full schedule, and teams competing
This is a college racing event, not a home upgrade story, but it's worth noting for anyone curious about solar technology in action. A record 42 college teams from the US, Canada, Belgium, and the Netherlands are competing in the Formula Sun Grand Prix, a track race for hand-built solar-powered cars, held July 21-23 at Brainerd International Raceway in Minnesota. The event is free and open to the public, with only a waiver required to attend. Teams that qualify move on to the American Solar Challenge, an 8-day, 1,500-plus mile road race from Minneapolis to Amarillo, Texas, running July 25 through August 1. The route follows the Great River Road and part of historic Route 66, marking that highway's 100th anniversary. A free public display of the cars happens July 24 at the University of Minnesota before the cars set out. None of this changes rebates, tax credits, or home equipment choices. It is a showcase of student-engineered solar vehicles, split into single-occupant cars built for efficiency and multi-occupant cars built for practicality. For anyone interested in how solar cells and battery systems perform in real-world conditions, the race offers a look at the technology in a different context than rooftop panels or home batteries, but there is no direct connection to home energy programs or costs.
July 4th Green Deals: Bluetti Summer Power Sale exclusives, Hiboy EX11 full suspension e-bike $700 off, EcoFlow flash sale, and much more
A batch of July 4th sales is running on backup power stations and electric bikes, which may interest anyone thinking about home backup power or alternative transportation. Bluetti's Summer Power Sale includes portable power stations, with a new FridgePower Station and bundle deals starting at $807. These stations store electricity and can run appliances during an outage, similar to a battery backup. E-bike and e-scooter shoppers can find discounts up to 58 percent through Hiboy's sale, including a restocked EX11 full-suspension electric bike priced at $1,300. Separately, EcoFlow is closing out an extended flash sale on power stations, with deals starting at $1,149. Other retailers, including Velotric and Heybike, are also running their own July 4th e-bike sales with prices starting around $999. None of this involves rebates, government programs, or home energy-efficiency upgrades directly. It is simply a roundup of holiday sales on portable power and electric bike products. If you have been considering a portable power station for outages or backup power, or an e-bike for shorter trips, these are the kinds of seasonal price cuts worth comparing against your own needs before deciding whether the savings make sense for you.
UK EV registrations hit 30% share in June as Tesla rebounds 42%
Electric cars made up nearly 30% of new car sales in the UK in June, one of the strongest months on record outside the usual spring and fall sales peaks. Battery-electric registrations jumped 38% to 64,440 units, even as the overall new car market grew 15%. Part of the push came from higher fuel prices, which are making electric cars look more attractive next to gas models. The UK's government mandate requiring a rising share of zero-emission car sales each year is also a factor, and the country is now growing EV sales faster than the broader European market. Tesla had a strong month too, with UK sales up 42% year over year to 12,403 vehicles. That looks like a real comeback after a rough year in Europe, helped by refreshed versions of the Model Y and Model 3 and lower prices. But the comparison is against a very weak year-ago period, so it's more a recovery than a leap to new highs. BYD, the Chinese automaker, kept growing too, up 9% to 2,999 units, though still well behind Tesla's UK volume. None of this changes rebate programs or costs for US homeowners directly, since it's about UK car sales. But it points to a broader trend: as fuel costs rise, more drivers are switching to electric, which for homeowners already means more interest in charging at home and pairing an EV with solar or other home energy upgrades to lower running costs.
First-ever Volvo A30 Electric articulated haul trucks get to work
This news is about heavy construction equipment, not something that shows up in a driveway, but it's a sign of where electric machinery is headed. Volvo has delivered its first electric articulated haul trucks, called the A30 Electric, to a contractor in Norway working on a hydropower project. These are large 30-ton trucks used to move material at construction sites, and this marks the first time they've gone from prototype to actual job-site use. The trucks run on a 245 kWh battery and a 350 kW electric motor, with enough power to match diesel equivalents while producing zero emissions. That matters on this particular project because the trucks will operate inside a tunnel being built for the hydropower plant, where running electric instead of diesel means cleaner air underground for workers. The hydropower project itself is expected to produce more than 100 GWh of renewable electricity a year once finished in 2029. There's no direct link here to home energy upgrades or rebates. But it's a data point on the broader shift toward electrifying heavy equipment, which can factor into how "green" large infrastructure and energy projects are from the start. If you're tracking where your electricity might eventually come from, projects like this hydropower plant, built with lower-emission construction methods, are part of that supply picture, even if the equipment itself has nothing to do with your own house.
Tesla maps a tiny Robotaxi zone in Miami while it still can’t scale Texas
Tesla has published a map for a Robotaxi service area in Miami, covering a small piece of the metro around West Miami and stretching toward Doral and Sweetwater. It skips downtown Miami, Miami Beach, the airport, and most of Coral Gables. Miami was one of five cities Tesla had targeted for a first-half 2026 launch, along with Phoenix, Orlando, Tampa, and Las Vegas, though that timeline has since softened. This news is more about self-driving robotaxi service than home energy upgrades, but it's a reminder of how slowly Tesla's autonomous driving rollout has gone. In Austin, where Tesla launched Robotaxi a year ago, the fleet is still small — around 50 vehicles total, with far fewer running without a safety supervisor onboard. That unsupervised fleet has actually been shrinking, down to roughly 14 active cars from a peak of about 25. Even after Tesla expanded its Austin coverage to the whole metro area, wait times often topped 15 minutes, and more than a quarter of the time, no car was available. Tesla's own executives have said safety validation, not mapping, is the bottleneck, and they're waiting on a rewritten version of the driving software before expanding further. For a homeowner, there's no direct action here. It's simply a sign that drawing a service area on a map is easy for Tesla, but running a real fleet of driverless cars safely at scale has proven much harder, in Texas and now in Florida.
The coolest e-bikes (and things) we saw at Eurobike 2026
This roundup covers e-bike trends from a European bicycle trade show and doesn't touch on home energy upgrades, rebates, or anything relevant to a homeowner planning efficiency improvements. It's about new bicycle and cargo bike technology, not household systems like heating, insulation, or electrical work. Since this falls outside topics that affect home energy decisions, there isn't a meaningful summary to offer in that context. If you're looking for news on heat pumps, weatherization programs, rebate deadlines, or similar home upgrade topics, that would be a better fit for this kind of summary.
Subaru’s new Trailseeker EV starts at $40,000
Subaru has released pricing for its 2027 Trailseeker, an electric SUV, with a starting price of $39,995, the same as the current model. It comes in three trims: Premium ($39,995), Limited ($43,995), and Touring ($46,555), plus a destination fee of $1,475 (higher in Alaska and slightly different in a few Northeastern states). The Trailseeker uses a 74.7 kWh battery for up to 281 miles of range, and it charges through the NACS port used by Tesla's charging network, with DC fast charging up to 150 kW that can take it from 10 to 80 percent charge in as little as 28 minutes. For homeowners weighing an EV alongside home charging plans, the Trailseeker's standard all-wheel drive, 8.3 inches of ground clearance, and towing capacity up to 3,500 pounds make it more suited to rougher driveways or towing needs than some rivals. All trims include Subaru's EyeSight driver assist system, and higher trims add features like heated rear seats, a panoramic glass roof, and ventilated front seats. The base trim alone offers dual wireless phone chargers and a 14-inch center touchscreen with wireless Apple CarPlay and Android Auto. The new Trailseeker goes on sale this fall in six colors, with an extra $395 for the Daybreak Blue Pearl option. It's priced close to the Tesla Model Y, though the Model Y AWD offers slightly more range at 294 miles. Subaru's smaller Uncharted EV, announced last week, starts even lower at $35,000.
Podcast: Tesla Model YL, Q2 deliveries, BMW iX5, and more
This one's about electric vehicles, not home energy upgrades, so there isn't much here that touches your house directly. The roundup covers a weekly podcast discussing Tesla's new Model Y L (a six-seat version with 325 miles of range, priced at $61,990), Tesla's second-quarter delivery numbers, and a first look at the BMW iX5, which is being positioned with 525 miles of range and fast charging. Other items on the list include Rivian's delivery results and an updated full-year outlook, a new electric Subaru Trailseeker starting at $40,000, and leadership changes at Lucid following layoffs. There's also mention of Tesla's driver-assistance software rollout and a small robotaxi service area in Miami. None of this involves home electrification, weatherization, heat pumps, or rebate programs. If you're weighing an EV purchase alongside home upgrades like a heat pump or rooftop solar, the range and pricing figures here might be useful context, but there's no new information on tax credits, utility incentives, or charging equipment for your home.
The Hyundai IONIQ 5 remains a top-selling EV as sales cross 20,000 in the first half of 2026
This is car sales news, not directly about home energy upgrades, but it does touch on the broader shift toward electric vehicles that some homeowners are weighing alongside things like home chargers or solar. Hyundai's IONIQ 5 electric SUV sold over 20,000 units in the US during the first half of 2026, up 9% from about 19,000 a year earlier. That put it ahead of the Chevy Equinox EV and the Toyota bZ, two of its main rivals. Hyundai's overall US sales hit a company record too, with 450,568 vehicles sold, a 3% increase over last year, and electrified models (hybrids and EVs combined) making up a third of that total. Hybrid sales jumped 71% in the spring quarter, led by models like the Tucson and Santa Fe. Other electric models had a rougher stretch. Ford's Mustang Mach-E sales fell 47%, and Honda's Prologue dropped 48%. Hyundai's larger three-row electric SUV, the IONIQ 9, also grew fast, up 380% to nearly 4,900 sold, though it's a smaller piece of the market. Both IONIQ models are built at Hyundai's plant near Savannah, Georgia. For a homeowner thinking about an EV alongside a home charger or solar setup, this mostly signals that the IONIQ 5 is a proven, popular choice with strong momentum, while some competing electric SUVs are seeing softer demand this year.
Volkswagen’s next electric SUV is almost here, and it’s not just a rebadged ID.4 [Images]
This news is about a car, not a home upgrade, but it may interest homeowners weighing an electric vehicle alongside other energy plans. Volkswagen is retiring its ID.4 electric SUV and replacing it with a redesigned model called the ID. Tiguan, expected to debut by the end of 2026. Spy photos show a more traditional SUV shape with a squared-off front end, new headlights, a redesigned hood, and doors with pop-out handles, all styled closer to VW's gas-powered Tiguan. The new SUV will ride on Volkswagen's updated MEB+ platform, already used in the ID. Polo and ID.3 Neo, and is expected to bring a redesigned interior with a new infotainment system and a return of physical buttons for climate controls, based on driver feedback. Volkswagen has not released battery or range figures for the new model, but says recent updates to batteries and electric drive systems should improve on the current ID.4, which offers up to 291 miles of range in rear-wheel-drive form and 263 miles with all-wheel drive. For context, VW ended ID.4 production at its Chattanooga, Tennessee plant earlier this year, shifting that factory to gas-powered SUVs, though existing ID.4 stock is expected to last into 2027. The new ID. Tiguan will be built at VW's plant in Emden, Germany. If you're considering an EV purchase to pair with home charging or solar plans, this is one more model to watch for when it arrives.
Wheel-E Podcast: Gazelle’s Bosch hub motor bikes, Eurobike, more
This is an e-bike news roundup, not directly about home energy upgrades, so there's little here that affects a homeowner's retrofit plans. Still, a few items may interest anyone weighing electric bikes as a lower-cost, lower-energy alternative to a car for local trips. Gazelle has a new e-bike using a Bosch hub motor design, and Monarc introduced a commuter e-bike called the Tracer with dual batteries and a 5-year warranty. DJI, known for its e-mountain-bike motors, is moving into a new "electric SUV bike" category. A company called Amble also showed off a street-legal electric buggy that can go 40 mph, blurring the line between bike and small vehicle. On the regulatory side, the Consumer Product Safety Commission (CPSC) is considering a new rule that could change safety standards for e-bikes sold in the US. Separately, Florida's governor vetoed an e-bike safety bill that had passed unanimously in the state legislature. Neither of these changes is final or explained in detail here, but they signal that e-bike rules may shift depending on where you live, similar to how energy rebates and codes vary by state. If you already own or are considering an e-bike, it may be worth keeping an eye on how these safety rules develop in your state, since they could affect what's available or required for e-bikes down the road.
Tesla driver charged with manslaughter in Katy crash was Googling ‘FSD too timid’
This is a story about a fatal crash, not an energy-efficiency upgrade, so it falls outside what Retrofit Relay usually covers for homeowners planning energy work. Still, here is what happened: a Tesla driver in Katy, Texas has been charged with manslaughter after his car crashed into a home in June, killing a 76-year-old woman inside. Prosecutors say the driver, who was doing DoorDash deliveries, had Tesla's Full Self-Driving (FSD) system engaged but pressed the accelerator himself, overriding the car's speed control while FSD kept steering. The car reportedly reached about 73 mph in a residential area before hitting a curb, going airborne, and crashing through the house. Investigators found no mechanical failure and no medical cause like a seizure or stroke. They did find recent Google searches from the driver's phone about FSD being "too timid" or "not aggressive enough." The driver faces a second-degree felony charge, is out on bond, and is due back in court soon. The victim's family has also filed a separate lawsuit against Tesla. For homeowners, this story has no direct bearing on energy upgrades, rebates, or home efficiency. It is included here only as a news item about a serious traffic incident involving a home, not as guidance on retrofit planning.
Major energy-affordability bill passes Massachusetts Senate
The Massachusetts Senate has passed a broad energy bill aimed at cutting utility costs, with backers saying it could save residents $14 billion over ten years. The state has some of the highest utility bills in the country, and the bill takes aim at that in several ways: changing how the state buys energy, adding rules for third-party electric suppliers, letting utilities borrow at lower cost for certain projects, and phasing out a major source of gas-line spending. It also allows homeowners to use plug-in solar systems, a small-scale setup that plugs into a regular outlet, similar to a balcony solar panel. Supporters say weaning the state off gas is central to bringing bills down, since gas costs are driving much of the current pain. One point matters directly for anyone who might do efficiency work on their home: the Senate version does not cut funding for Mass Save, the state's energy-efficiency rebate and incentive program. That's a sharp contrast to the House version, which calls for slashing Mass Save's budget by $1 billion, roughly two-thirds of what's left in its current three-year budget. Supporters of that cut say it would lower bills faster; opponents say the savings would be minor and that efficiency spending actually holds down costs for everyone over time. Because the House and Senate bills differ, especially on Mass Save funding, lawmakers now have to reconcile the two versions before anything becomes final, with both chambers voting again on whatever compromise emerges. Until then, it's not yet settled whether Mass Save funding will survive intact.
Trump's ‘big, beautiful’ law was supposed to kill clean energy. It didn't.
A year ago, President Trump signed a law that repealed much of the Inflation Reduction Act, the main federal law that used tax credits to make wind, solar, and battery projects cheaper to build. As of this weekend, those tax credits are gone for developers unless they had already started construction. Despite that, clean energy has kept growing: more than 90% of new power plants built in the U.S. in 2025 were solar, wind, or battery projects, and the government expects a similar share this year. The reason is simple demand — data centers, electric heating, and electric cars are pushing electricity use up fast, and renewables and batteries are the only options that can be built quickly enough to keep pace, since gas-power equipment faces long supply delays. This doesn't mean clean energy is unaffected. One estimate suggests the loss of tax credits could cut new clean-energy construction roughly in half over the next decade, with the steepest drop later on. The administration has also blocked some permits for wind and solar projects and paid companies to cancel offshore wind leases, including a recent $129 million payout to Duke Energy to drop a project off North Carolina. For homeowners, this is mostly background context: it explains why your region's power supply is still adding mostly solar, wind, and battery capacity even as federal support shrinks. It does not change any current home energy-efficiency rebate or incentive on its own, but it's a sign that the broader shift toward electrification — heat pumps, electric vehicles, home solar — is continuing despite policy headwinds.
The Energy Shock Is Exposing the Real Cost of Volatility and Making the Case for LEED
This story is about big commercial office buildings, not single-family homes, but the trend behind it is worth knowing. Electricity and natural gas prices have been swinging harder and less predictably lately, driven by rising demand, grid strain, and fuel costs. For any building, the less energy it uses, the less exposed it is to those price spikes. The piece points to examples like the Empire State Building, which cut energy use by about 38% through a major retrofit and now saves roughly $4.4 million a year, and the National Renewable Energy Laboratory's headquarters in Colorado, which uses daylighting, natural ventilation, and onsite solar to run on far less purchased electricity than a typical office building. In both cases, lower energy use didn't just save money, it made costs more predictable when prices elsewhere are jumping around. The larger point is that buildings certified under LEED (a widely used green-building rating system) tend to command higher rents and sale prices, partly because tenants and investors see efficiency as protection against volatile energy bills. None of this involves a rebate or program a homeowner can apply for. But the underlying idea applies at any scale: a house that uses less energy and can shift or manage its power use is less vulnerable to the kind of price spikes now showing up on utility bills nationwide.
In Ohio, solar is no big threat to farmland
A new map from the Solar Energy Industries Association shows that solar panels cover less than one-seventh of 1% of Ohio's prime farmland, even though farmland loss is one of the most common arguments used to block large-scale solar projects in the state. Of Ohio's 37 square miles of solar generation area, about 31 square miles overlap with prime farmland. By comparison, golf courses take up more than 2.7 times that acreage, and suburban sprawl from 2014 through 2024 consumed more than five times as much farmland. Ohio law already lets counties ban or add hurdles to solar and wind projects, and several counties, including Richland County, have used this power to restrict them, often citing a desire to preserve farmland. This pattern isn't unique to Ohio: officials in other states have passed similar restrictions, and federal agriculture officials have also pushed back against solar on farmland. Advocates note that Ohio farmers already use a large share of active farmland to grow corn for ethanol, which requires roughly 30 times more land per unit of energy than solar, according to a 2025 study. None of this changes rules for homeowners directly, but it matters if solar development is a local issue where you live, since decisions about zoning and land use happen at the county or township level. Some projects are experimenting with combining solar and farming, such as sheep grazing under panels or growing crops alongside them, suggesting the two uses don't have to be mutually exclusive.
Electric trucks look a lot more appealing when gas prices are sky-high
High gas and diesel prices are making electric delivery trucks a much better deal to run, according to new data from truck maker Workhorse. The company operates both gas and electric cargo vans on the same routes in Ohio for FedEx delivery work, which lets it directly compare costs. Last year, electric trucks saved about 42.5 cents per mile over gas ones. By May, with Ohio gas prices up to $4.83 a gallon, that savings jumped to 73.6 cents per mile — roughly $11,000 a year for a van driving 50 miles a day. This is mostly a story about commercial delivery fleets, not personal vehicles, but it shows the same math that applies to any gas-powered vs. electric comparison: electric vehicles cost more up front but less to fuel and maintain. Electric trucks still run 30% to 100% more than gas versions to buy, though Workhorse recently cut the price of its standard electric van by about $60,000, bringing it close to the cost of top-end gas models. Payback time — how long it takes the fuel savings to cover that extra upfront cost — depends heavily on state incentives; in California and Washington, which offer generous rebates, buyers can recoup the cost difference in three to five years. Federal tax credits for electric vehicles have mostly been eliminated, but some states still offer their own incentives. If you're weighing an electric vehicle for your household, checking what your own state currently offers is the most reliable way to see whether the numbers work in your favor, since incentives and fuel prices vary a lot by location and change often.
Kia axed its affordable EV, but a replacement is set to go on sale soon
Kia is dropping the electric version of its Niro for the 2027 model year, keeping only the hybrid. The Niro EV had been one of the more affordable electric vehicles on the market since 2019, starting under $40,000 with 239 miles of range, but Kia is replacing it with a newer, cheaper model: the EV3. The EV3 is expected to go on sale later this year, with pricing likely starting under $35,000, though Kia hasn't confirmed the final price. It comes in five trims and two battery sizes. The base battery (58.3 kWh) is estimated to deliver around 220 miles of range, while the larger battery (81.4 kWh) is estimated at about 320 miles for front-wheel-drive versions. All-wheel drive is available on some trims and standard on others. Fast charging can take the smaller battery from 10% to 80% in about 29 minutes, and the larger one about 31 minutes. Every EV3 comes with Tesla's NACS charging port built in, so it can plug into Tesla Supercharger stations without an adapter. For homeowners thinking about EV charging at home, the range and charging specs matter more than the badge swap. If you were eyeing the Niro EV as an affordable option, the EV3 is shaping up to be its direct, likely cheaper and longer-range replacement once it arrives in dealerships.
Polestar EVs are a smoking deal at $25k off now that they’re banned in the US
The federal government recently moved to ban Polestar, a Swedish electric car brand owned by China's Geely, from selling connected vehicles in the US starting with the 2027 model year, citing cybersecurity concerns. Polestar builds its Polestar 3 SUV in South Carolina and its Polestar 4 in South Korea, both running American-made Google software. In response, Polestar is now offering steep discounts to move remaining inventory. The Polestar 4, an electric coupe, is discounted by $25,000, dropping the starting price to about $31,400 directly through Polestar's website. That makes it one of the cheapest EVs in the country, behind only the Chevy Bolt EV at $27,000 and the Nissan Leaf at $30,000. The Polestar 3 SUV carries a $23,000 discount, bringing its starting price to $44,500, which is in line with other entry-level electric SUVs but for a more upscale vehicle. For anyone thinking about buying an EV, these deals could be worth a look, but there's uncertainty involved. The ban only affects sales of 2027 and later model years, so existing cars should remain drivable and able to receive software updates for now, since Polestar still sells globally. Still, buyers should weigh the long-term outlook for parts, service, and support given the regulatory situation. If you're weighing an EV purchase alongside other home energy upgrades, like solar panels or a home charger, this is a case where the deal is real but the company's US future is less certain than usual.
‘World’s largest’ second-life EV battery factory opens in just six weeks
A company in Vancouver, BC has opened what it calls the world's largest factory for turning old electric vehicle batteries into large-scale energy storage systems, and did so just six weeks after announcing the project. Moment Energy's new plant doesn't make new batteries. Instead, it takes EV batteries that are retired from cars, but still hold plenty of usable capacity, and rebuilds them into storage systems for places like data centers, hospitals, and factories. The idea is that a battery no longer strong enough to power a car still has years of useful life left when weight and size no longer matter. Recycling it right away wastes that capacity. The company expects to produce 1 gigawatt-hour of storage systems a year by 2030 and says the factory will create over 100 jobs directly, with more than 1,000 additional jobs supported across British Columbia. It was backed by a CA$4.9 million investment from a Canadian government agency and has raised more than US$100 million total, including a recent US$40 million funding round. This news doesn't involve a program or rebate for homeowners. But it points to a growing supply of cheaper, reused batteries heading into the energy storage market, which could eventually shape the cost and availability of battery storage products, including home batteries, as this kind of manufacturing scales up.
Iberdrola kicks off its first large-scale battery project in the US
Iberdrola, the Spanish energy giant, is building its first large-scale battery storage project in the US, in Gilliam County, Oregon. The Shutler project is expected to come online in 2027 with a capacity of 41 megawatts and the ability to store up to 82 megawatt-hours of electricity. That makes it a "two-hour battery," meaning it can put out its full power for about two hours before needing to recharge, a common setup for these grid-scale systems. Batteries like this one don't power individual homes directly. Instead, they store extra electricity generated from renewable sources, like solar and wind, and release it when demand is higher, such as evenings when solar output drops. This helps balance supply and demand across the grid and can make outages less likely. Iberdrola's US subsidiary, Avangrid, already operates about 3,000 megawatts of generation capacity in the Pacific Northwest, and this project adds to that regional footprint. For homeowners, this isn't something that changes your utility bill or your household setup right away. But it's part of a broader trend: utilities across the country are adding battery storage at a rapid pace because it lets them make better use of renewable power and keep the grid more stable. If you live in the Pacific Northwest, projects like this one may eventually mean a more reliable supply of electricity, particularly during periods of high demand or when renewable generation dips.
Tesla launches Model Y L in US — 6 seats, 325 miles, $61,990
Tesla has launched the Model Y L in the US, a longer version of its popular Model Y SUV with room for six people across three rows. The stretched body adds about 6 inches to the wheelbase, making space for real second-row captain's chairs and a usable third row, unlike the cramped extra seating Tesla added to the standard Model Y earlier this year. Tesla says it can go 0-60 mph in 4.4 seconds and travel 325 miles on a charge, with features like heated and ventilated seats, a second screen for rear passengers, and Tesla's supervised driver-assist system. The catch is price. This first version, called the "Launch Series," starts at $61,990 — more than Tesla's own high-performance Model Y and pricier than two direct rivals, the Kia EV9 ($54,900) and Hyundai Ioniq 9 ($58,955), both of which also offer three rows and strong range. Tesla often starts a new model with an expensive, fully loaded trim before adding cheaper versions later, so a lower-priced Model Y L may follow. For homeowners weighing an EV purchase, this mainly matters if you need genuine third-row seating and were considering Tesla, Kia, or Hyundai options. If you already own or plan to buy an EV, charging costs at home remain the bigger ongoing factor, and pairing an EV with home solar can help offset those costs regardless of which vehicle you choose.
The Bathing Porch
A 1913 Colonial Revival house in Southwest Portland, Oregon, recently went through a restoration that turned an old upstairs sleeping porch into a bathroom. Sleeping porches were screened rooms once used for fresh-air sleeping, common in older homes, and this one sat behind large windows and Ionic columns on the home's gabled end. The design/build firm Arciform converted it into a primary bathroom and closet with a handmade-tile floor, a brass soaking tub, and brass console sinks topped with marble. The bigger point for anyone with an old sleeping porch is a practical one: these rooms were built lighter than the rest of the house, since they were meant as outdoor-adjacent spaces rather than fully conditioned living areas. Turning one into year-round living space, especially a bathroom with a soaking tub, means updating the framing, insulation, and floor structure, and adding proper heating, cooling, and weather protection. This particular house is listed on the National Register of Historic Places, so the renovation was done carefully to preserve the original architectural details while making those structural and mechanical upgrades. If you have an old sleeping porch or similar lightly built addition, the takeaway is that converting it to a full-time room isn't just cosmetic. It usually calls for real structural and insulation work before you can rely on it as comfortable, code-ready living space in every season.
Hydrogen for heavy trucks is dead, says world’s 2nd-largest oil company
This one is more about trucking than home energy, but it does touch on the same battery-versus-hydrogen debate that shows up in some clean energy discussions. Sinopec, China's state-run oil company and the world's second-largest, published an internal update saying hydrogen fuel cells are losing the race to power heavy trucks. The company had expected hydrogen to eventually replace diesel in big trucks, similar to how electric vehicles replaced gasoline cars. Instead, battery-electric trucks are taking over that role too, helped by fast-improving batteries, charging speeds, and battery-swapping stations in China. Hydrogen has real drawbacks: it must be stored under pressure in heavy tanks, it leaks easily, and most of it today is made from fossil fuels rather than renewable electricity, so it is not as clean as it sounds. Sinopec still thinks hydrogen could carve out a niche in long-haul trucking, where range and cargo weight matter most, but says that will be harder as battery-electric trucks keep improving and spreading. None of this changes anything about home heating, insulation, or rebates. It is simply a sign of where battery technology is heading in general, since many of the same battery and charging advances that are pushing hydrogen out of trucking are also what makes home batteries, electric vehicles, and heat pumps more affordable and reliable over time.
People are willing to pay more for climate-proof wine, study shows
A new study out of Cornell looked at how winemakers might cope with a warming climate, and whether shoppers would still pay for the results. Researchers tested three approaches: putting up shade cloth to protect grapes from sun damage, switching to grape varieties that handle heat better, or moving vineyards to cooler regions altogether. In all three cases, when producers explained the change on the label, shoppers said they'd pay more for the wine, even when it meant giving up a famous name like Napa Valley. That last point matters most for growers, since some fixes are invisible to consumers (shade cloth) while others change what's actually in the bottle. Switching grape varieties or relocating means the wine label itself changes, say, from a Napa Cabernet to a Lake County Cabernet. Of the three options, relocating was least appealing to shoppers, but people still said they'd pay extra even for that. The study had limits: it surveyed just 300 people, mostly college-educated and under 40, who already said they care about environmental issues and read food labels. Real-world buyers may not be so consistent, and researchers noted a "novelty" effect could fade over time. Outside experts called the findings a useful step toward understanding the actual economics of climate adaptation in agriculture, though they cautioned that vineyards face other threats too, like hail, frost, and unpredictable rain, each with its own costs. For home gardeners or hobbyist growers, the takeaway is less about wine itself and more a reminder that consumers, in general, may be willing to pay for products that adapt visibly to climate change.
The Hyundai IONIQ 3 is the affordable electric hatch we want but can’t have
Hyundai has unveiled the IONIQ 3, a small electric hatchback built in Europe, but it isn't coming to the US. The car uses two battery options: 42.2 kWh, good for up to 213 miles of range, and 61 kWh, good for up to 308 miles. Both can charge from 10% to 80% in around 29 to 30 minutes on a fast charger. It also debuts Hyundai's new Pleos Connect infotainment system, a smartphone-like interface with a large touchscreen and an AI voice assistant that can answer questions or help find places nearby. Pricing hasn't been announced, but the base version is expected to start around $35,000 in Europe, with a sportier N-Line version costing roughly $11,700 more. For comparison, that starting price is similar to what Hyundai's IONIQ 5 costs in the US. None of this affects US buyers directly, since the IONIQ 3 is built at a plant in Turkey and importing it would likely cost too much under current tariffs. Hatchbacks also haven't sold well in the US compared with SUVs and trucks, making the car a less obvious fit for the American market anyway. If you're shopping for an electric vehicle in the US, Hyundai's IONIQ 5 remains available and is built domestically near Savannah, Georgia, and Kia is set to bring its EV3 compact SUV to the US later this year as a similarly priced alternative.
Toyota is paying up after canceled flagship EV triggers ‘unprecedented’ shock
This is car industry news and doesn't have much to do with home energy upgrades, but here's what happened: Toyota has canceled its flagship electric vehicle, the Lexus LF-ZC, which was supposed to showcase new battery technology and manufacturing methods. The vehicle was meant to offer roughly triple the driving range of Toyota's previous EV and charge in about 20 minutes. Toyota is now paying suppliers who had already invested in specialized equipment for the canceled model, with compensation potentially reaching tens of billions of yen. Toyota says the technology developed for this EV, including its new manufacturing process and a redesigned electronics platform, will carry over to a future vehicle, though no timeline has been given. The company's overall sales have fallen for four straight months, driven largely by a steep drop in China, even as its battery-electric vehicle sales have grown sharply this year compared to last. None of this changes anything about home energy incentives, heat pumps, insulation, or rebate programs. It is a story about strategy and financial fallout inside the auto industry as automakers work out how fast to shift from gas and hybrid vehicles to fully electric ones. If you're weighing an EV purchase alongside home upgrades like a heat pump or added insulation, this mainly signals that automakers, including Toyota, are still adjusting their electric vehicle plans, so model availability and timelines may keep shifting.
Lucid overhauls its entire C-suite under new CEO after 18% layoffs
Lucid Motors, the electric vehicle maker, has replaced nearly its entire top leadership team under new CEO Silvio Napoli, who took over in June. New executives are joining as chief financial officer, chief technology officer, chief customer officer, and chief transformation officer, and the company has created a new business unit, Lucid Technologies, to focus on self-driving cars, robotaxis, and artificial intelligence. The moves come just over a week after Lucid cut about 18% of its workforce, roughly 1,500 jobs, and withdrew its 2026 production forecast of 25,000 to 27,000 vehicles. The shake-up follows weak sales. Lucid delivered 3,953 vehicles in the second quarter, up from a year earlier but with production down 13% from the prior quarter. For the first half of 2026 the company has delivered just over 7,000 vehicles, well short of earlier goals. Full financial results, including how much cash the company is burning through, are due August 4. This is a story about a struggling automaker restructuring its leadership, not a change to any energy program or rebate. It matters to homeowners mainly if you already own or are considering a Lucid electric vehicle, since the company's financial troubles and leadership turnover could affect service, pricing, or future model availability. If you're weighing an EV purchase alongside home solar or a home charger, it may be worth watching whether Lucid stabilizes before its August earnings report.
Elon Musk shuts down ‘4D chess’ theory on Tesla Optimus production
This is Tesla news, not a home energy story, but here's the gist. Elon Musk pushed back on a fan theory that Tesla was secretly ahead of schedule on Optimus, its humanoid robot. A supporter had argued that Tesla's silence about its next robot demo meant the company was quietly further along than it let on. Musk shut that down directly, saying production "will be extremely slow at first" because everything about building the robot is new, unlike building a car. That matches what Tesla has already said. On an earlier earnings call, Musk said robot production would start at the company's Fremont, California plant around late July or August, with output he called "quite slow" and impossible to predict this year, since the robot has roughly 10,000 unique parts on a brand-new production line. Tesla converted part of that same Fremont factory, previously used to build Model S and Model X cars, over to robot production. The company has also delayed the robot's next public demo several times through the year. This follows a pattern: Musk once predicted Tesla would build around 10,000 robots in 2025 and have 1,000 doing real work by year's end. Neither happened. Tesla now talks about building 50,000 to 100,000 robots in 2026, with much larger production goals down the road, but the near-term picture Musk describes is a slow, uncertain start rather than a hidden breakthrough.
Velotric + Heybike July 4th e-bike sales with up to $828 savings, Samsung Bespoke AI ventless washer/dryer $1,850, Greenworks, more
This roundup is mostly e-bike and appliance deals rather than home energy upgrades, but one item stands out for anyone thinking about laundry: Samsung's Bespoke AI All-in-One Washer/Dryer Combo is down to $1,850. It's a ventless, heat-pump model, meaning it dries clothes without needing an exterior vent, which can make installation easier in homes where running ductwork outside isn't practical. Heat-pump dryers also tend to use less energy than standard electric dryers, so this could be worth a look if you're replacing an aging laundry set. The rest of the sale centers on e-bikes. Velotric's July 4th sale offers up to $812 in savings, including its Fold 1 Plus folding e-bike (with a swappable sensor system and Apple Find My tracking) at a low of $1,399. Heybike has its own July 4th sale with up to $828 off, with prices starting at $999. Neither of these relates to home energy efficiency, but they're relevant if you're weighing an e-bike as a lower-cost, lower-energy way to get around. Other deals mentioned include a 60V Greenworks pole saw and a 600 CFM Worx Trivac leaf blower/vacuum, both yard tools rather than energy upgrades. A few holdover deals are also listed, including Juiced Scrambler e-bike bundles and a Baseus solar security camera. None of these come with rebate or program details, so if you're specifically hunting for energy-efficiency savings, the washer/dryer deal is the one most directly tied to your home.
The Jeep Recon EV will launch in Europe, plus a new China-made SUV and more
This is about electric vehicles, not home energy upgrades, so it does not affect any decisions about your house. But here's a plain summary for context. Jeep confirmed its Recon EV, an electric off-roader similar in style to the Wrangler, will still launch in Europe despite a report suggesting otherwise. The Recon EV already went on sale in the US and Canada, and the European version is now set for early 2027. Jeep also plans to bring its Wagoneer S electric SUV to Europe, though details on that model haven't been finalized. Beyond the Recon, Jeep's parent company Stellantis is planning three more SUVs for Europe. The biggest is a flagship model that will actually be built in China through a partnership with Chinese automaker Dongfeng, using Dongfeng's underlying technology, then exported to Europe and other markets. It will come in hybrid, fully electric, and possibly extended-range electric versions. Two smaller SUVs will also join the lineup, one compact and one closer in size to Jeep's Compass model. Both will run on Stellantis's new modular vehicle platform, called STLA One, which is built to support electric, hybrid, and plug-in hybrid versions of the same vehicle along with newer onboard software and tech features. None of this involves home energy equipment, rebates, or weatherization programs. It's simply news about which electric and hybrid vehicles Jeep plans to sell in Europe over the next couple of years.
How an NYC high-rise is keeping cool with geothermal energy
A commercial office building in Manhattan, 555 Greenwich St., has become New York City's first fossil-fuel-free commercial office building, according to its owners. The 16-story building uses 68 geothermal piles that run nearly 120 feet underground, moving heat into the earth in summer and pulling it back out in winter. This system, paired with large rooftop air-source heat pumps (which move heat using electricity rather than burning gas), covers all the building's heating and cooling needs. The owners estimate the building will save around $3 million in energy costs over 15 years. The building is part of a larger effort in New York City, where laws are pushing new construction and large existing buildings toward electric, fossil-fuel-free systems on set timelines through 2030. A neighboring, century-old building is being retrofitted floor by floor with heat pumps and a shared water-pipe network that moves heat where it's needed, funded partly by a $5 million state grant plus private money. For homeowners, this is mostly a signal of where heating and cooling technology is headed rather than something with immediate rules attached. Geothermal and heat pump systems, once mostly discussed for large buildings, are increasingly proven at scale in dense cities. The article also notes that New York state recently weakened a major climate target, which is creating some uncertainty among building owners about how firm future deadlines really are — a reminder that state and local rules can shift, even as individual buildings push ahead with upgrades on their own.
Martha’s Vineyard solar array will cut bills for low-income islanders
A new rooftop solar project on Martha's Vineyard is set to lower energy bills for hundreds of low-income, year-round residents on the island, which has some of the highest electricity costs in the country despite its reputation as a wealthy vacation spot. The 138-kilowatt system, installed on workforce housing tied to Martha's Vineyard Hospital, started running in June. Half the savings from the solar power will go toward the hospital workers living at the housing site. The other half, an estimated $550,000 over 25 years, will be shared among roughly 500 income-eligible households across the island through Vineyard Power's Resiliency and Affordability Program. As long as the system produces at least 70% of its expected output each year, $22,000 will be paid out annually to those households, a fixed amount that won't change with energy prices. Payments to participants are set to begin after the system's first full year of operation. The project came out of SolarShare, a new model from the nonprofit PowerOptions Connect that uses donated funds to cut upfront solar costs so more of the financial benefit can flow directly to people struggling with high energy bills, rather than just the property owner. It was funded partly through grants from the Massachusetts Clean Energy Center and partnerships with Vineyard Power, which manages community funds from the nearby Vineyard Wind 1 offshore wind project. PowerOptions Connect says it's now discussing similar projects with partners elsewhere in Massachusetts, Connecticut, Maine, and Rhode Island.
Peeling Paint Mystery
Peeling exterior paint often gets blamed on wall insulation added without a proper vapor barrier (a layer that keeps moisture from migrating into the wall). But that's not the only cause, and it may not even be the main one. If your walls aren't insulated, as one homeowner found after paint failed just three years after application, the real source is likely something simpler: water getting into the wall from a roofing, flashing, or gutter leak. Materials like plaster, low-fired brick, lime mortar, and wood soak up water and hold onto it for days or weeks. That trapped moisture can keep new paint from bonding well, or push a good paint job off the wall soon after a leak starts. So peeling paint can be a sign of a leak elsewhere in the house, not just a problem with the paint itself. Tracking down the cause starts with what one expert calls a moisture inventory: a walk-through that looks for every possible source of unwanted water, including combustion exhaust, damp firewood, ground moisture from a dirt crawlspace, humidifiers, plumbing leaks, and rain or snowmelt getting through gaps in the exterior. Checking the roof, flashing, and gutters from a ladder, running a garden hose over the walls while someone watches inside, or inspecting during a real rainstorm can help pinpoint where water is entering. If none of that turns up a leak, the paint failure may come down to condensation inside the wall instead.
One year after the Texas floods, home feels further away than ever
A year after the July 2025 floods killed 139 people in central Texas and caused $1.1 billion in property damage, families in Sandy Creek are still stuck between damaged homes and rebuilding costs they cannot afford. Many properties sit in a floodplain, and federal rules require that if flood damage equals at least 50 percent of a home's pre-flood value, the whole structure must be brought up to current code. In Travis County, that means elevating homes at least 2 feet above expected 100-year flood height — for one family, building 12 feet in the air with a lift to the door. That kind of work can add more than $100,000 to a rebuild, on top of engineering and survey costs, and one resident estimated 98 percent of her neighbors cannot afford it. Help has come in pieces rather than as a full solution: FEMA assistance capped at $43,600 per household, a county donation fund, church and nonprofit grants, and a celebrity benefit concert. Only 2.4 percent of affected households had flood insurance, which usually just restores what was lost rather than covering new code requirements. Renters and landlords often fall outside nonprofit aid rules entirely, and multigenerational properties have caused some residents to be overlooked by relief programs built around single-owner homes. The broader lesson for homeowners in flood-prone areas is that federal "substantial damage" rules can turn a bad flood into a much larger, costlier rebuilding project, and that insurance, county programs, and nonprofit aid vary widely and rarely cover the full gap. Checking your own flood insurance coverage and understanding local floodplain building rules before a disaster hits is worth doing now rather than after.
Betting On Our Nearest Star That Gives Us Life And Energy
This piece from the Southern Alliance for Clean Energy makes the case that solar power, paired with battery storage, has become cheaper and more reliable than fossil fuel alternatives, and argues the main obstacles now are outdated rules rather than cost or technology. It points to the group's "Solar in the Southeast" report as evidence of solar's fast growth across the region, and to a separate analysis of plug-in solar (small solar setups that connect directly into a home's outlet) showing the technology is safe and accessible in many places already. The piece is critical of large monopoly utilities, arguing their profit model favors building expensive gas plants and pipelines over solar. As an example, it cites North Carolina regulators approving at least seven large gas projects since 2022, with more expected. On the ground, it highlights two examples: Atlanta's Westside "Resilience Corridor," which combines solar, storage, and weatherization (sealing and insulating a home to cut energy waste) with job training to lower bills in the neighborhood, and electric vehicles being used as backup power sources for homes during outages. There's no new program, deadline, or rebate here for homeowners to act on. It's a broader argument about where the energy system is headed, using regional examples to make the point that home solar and batteries are increasingly viable options worth understanding, especially as utility rules and rate structures continue to shift.
Will Dominion merger benefit SC ratepayers? Regulatory scrutiny over deal sought
The page linked under this headline didn't actually load the story about the Dominion merger in South Carolina — what came through was navigation menus, cookie notices, and links to unrelated articles about NOAA climate data and a hurricane recollection. There's no usable information here about what the merger involves, who's asking for regulatory scrutiny, or how it might affect Dominion Energy customers' rates in South Carolina. If you're a Dominion Energy South Carolina customer wondering whether a corporate merger could change your electric bill, that's a fair question to ask, but nothing in this particular page answers it. Utility mergers can affect rates, service reliability, and long-term infrastructure investment, all of which eventually show up on residential bills, but the specifics of this deal, including who the merger partner is and what state regulators are reviewing, aren't included in what loaded here. If you want to know how this might touch your own household budget or any upcoming rate case in South Carolina, it would be worth checking directly with the South Carolina Public Service Commission or Dominion Energy's customer communications for the actual merger details and any public comment period tied to it.
Rot-Proof Trim
If you're tired of replacing wood trim, porch posts, or fencing that keeps rotting, there are now alternatives that hold up to weather without losing the look of traditional woodwork. Companies make fiber-reinforced polymer columns, PVC trim boards, and engineered porch planks that can be cut and shaped like lumber, then painted so they're hard to tell apart from real wood once installed. Brands mentioned include AZEK and WindsorOne, which make engineered beadboard for porch ceilings, Aeratis, which offers PVC beaded-board ceilings and planking, Fiberon, a wood-plastic composite decking made for covered porches, and the Gingerbread Man, which makes decorative brackets from an engineered hardwood composite called Extira that resists splitting better than solid wood. If you want to keep real wood but reduce future rot, some shops will custom-mill trim from rot-resistant species like Port Orford cedar. For homeowners dealing with rotted rafter tails rather than trim, a repair called a Dutchman patch can fix the damage without removing the roof. It involves cutting out the decayed wood, shaping a new wood patch to fit the opening, treating the old wood with fungicide, and gluing the patch in with waterproof wood epoxy before sanding it smooth and repainting. If the rafter ends carry structural weight, the roofline gets temporarily braced with lumber during the repair. This is a targeted fix for isolated rot rather than a full replacement, which can save both the wood and the look of an older roofline.
Building Performance Association Launches National Search for Next Chief Executive Officer
The Building Performance Association, an industry group that supports contractors, utilities, nonprofits, and others working on home energy efficiency and weatherization (sealing and insulating homes to cut energy waste), is searching for a new Chief Executive Officer. The group's board says it wants a leader who can help the organization grow as demand rises for work that makes homes more efficient and healthy. BPA formed in 2018 through the merger of three groups: Efficiency First, Home Energy Magazine, and the Home Performance Coalition. It works to strengthen the home performance industry broadly, rather than serving homeowners directly. The new CEO will oversee the group's finances, programs, and strategic plan, and will lead fundraising and outreach across the industry. This is a leadership and organizational change within a trade association, not a program or policy shift that affects rebates, incentives, or upgrade options for your house. If you're planning an energy upgrade, this news doesn't change what's available to you or any deadlines you might be tracking. It mainly signals that a group involved in shaping industry standards and training is in a transition period as it looks for new leadership.
Stamped-Metal Roof
A homeowner in Boerne, Texas, wrote in asking about an old photo showing their late 19th-century house with a roof covered in some kind of embossed material, flatter than tile. Old House Journal editor Patricia Poore confirmed it was likely stamped-metal shingles, a lightweight roofing style that dates to the 1880s and was especially popular around the turn of the 20th century. If you have an older home and want to match that historic look, two classic shingle designs are still made today by Berridge Manufacturing, using a zinc-and-aluminum alloy called Galvalume. They come with a clear acrylic finish or a warrantied fluoropolymer coating in 33 standard colors, plus custom colors on request. The shingles install with hidden fasteners over solid roof sheathing and cover 9 by 12 inches each. They're sold through distributors and contractors, and Berridge's website has photos and specs if you want to see what the style looks like before deciding whether it fits your house. The same issue also covered ways to protect metal features around a house, like railings, fences, and window hardware, from rust. Options mentioned include Ospho, a rust converter that turns rust into a hard, paint-ready surface; a linseed-oil soap bath for small removable metal pieces like doorknobs; Penetrol, an additive that also works as a standalone rust-inhibiting coating; and clear-coat lacquers suited to UV or salt exposure, some of which can go directly on bare metal without a primer.
Urban trees aren’t just nice, scientists say — they’re mandatory
A group of scientists is arguing that city trees and greenery should be treated as required infrastructure, not a nice-to-have. Writing in the journal PLOS Climate, the researchers say urban trees cool neighborhoods by providing shade and releasing water vapor, help soak up stormwater to reduce flooding, clean the air, support mental health, and provide habitat for birds and other animals. Their essay lays out a four-part plan for cities: dedicate real budget to planting and maintaining trees (not just relying on one-time donations), make sure greenery is spread equitably across rich and poor neighborhoods alike, involve residents in decisions about what gets planted, and use science to choose tree species that can survive rising temperatures over the next few decades. The equity point matters for anyone living in a neighborhood with fewer trees. Researchers note that wealthier areas tend to have more shade and lower temperatures, while neighborhoods with less tree cover — often lower-income areas — face worse urban heat, especially for residents without air conditioning. The essay also points to a recent finding that every dollar cities spend on parks and recreation returns about three dollars in local economic benefit, through increased exercise, foot traffic, and nearby spending. This is a call for city governments and legislatures to change how they plan and fund urban forestry, not a program homeowners can sign up for. But it may be worth paying attention to whether your own city or town budgets for tree planting and maintenance, and whether that effort reaches your neighborhood specifically.
DOE releases updated guidance for IRA Home Energy Rebate Programs
The Department of Energy has issued new rules for the $8.8 billion Home Energy Rebate Programs created under the Inflation Reduction Act. These rebates, known as HOMES and HEEHR, are meant to help homeowners pay for energy-efficiency and electrification upgrades, but most states have been stuck waiting for federal approval to launch their programs. The updated guidance is meant to clear that logjam. So far, twelve states and Washington, D.C. have started one or both programs; the rest have been in limbo. One change worth knowing about: under HEEHR, rebates can no longer be used to switch from gas to electric appliances, such as replacing a gas water heater or stove with an electric one. Rebates now apply only to upgrading equipment that is already electric to a more efficient version. There is one exception — if you have a fossil-fuel heating and cooling system, you can still get a rebate to add a heat pump, as long as you keep the old system in place rather than removing it. The guidance also drops the previous rule requiring 40% of each state's rebate money to go to low-income households, though a separate rule reserving 10% for low-income multifamily buildings stays in place. States with active programs now have until August 31 to update their plans to match these new rules. It's not yet clear how quickly other states will get approval to launch their own programs, so anyone hoping to use these rebates should watch for updates on what their own state offers.
Vermont is boosting new homes that can cut energy use in half
Vermont has a program pushing manufactured homes that use less than half the energy of standard new ones. Efficiency Vermont, the state's energy-efficiency utility, created the Advanced Manufactured Home standard in 2024, and 18 of these homes were just installed at Tri-Park Cooperative Housing in Brattleboro, the state's largest manufactured-home community. Builders get a $3,000-per-unit incentive to meet the standard, and any Vermonter can buy one of these homes and work with Efficiency Vermont to get it built. The homes are all-electric, with heat pumps for heating and cooling, heat-pump water heaters, extra insulation, high-efficiency windows, tighter air sealing, and continuous fresh-air ventilation. That combination cuts energy bills dramatically: older manufactured homes in Vermont often run about $4,000 a year in energy costs, largely from oil or propane heat, while an Advanced home can save roughly $2,700 a year compared with an existing manufactured home, and more than $1,300 a year compared with a new one built to current federal standards. These homes cost about $21,000 more upfront than a standard new manufactured home, but factoring in a 30-year mortgage and lower utility bills, the overall cost of ownership works out similar to a less efficient, fossil-fuel-heated home. A federal housing bill, the 21st Century ROAD to Housing Act, could eventually push these kinds of efficiency upgrades nationwide by requiring HUD to update manufactured-home efficiency rules regularly. But as of now, the bill's fate is uncertain after President Trump withheld his signature.
Connecticut’s new solar law is better than nothing
Connecticut Gov. Ned Lamont has signed a new law aimed at boosting solar power in the state. It extends the state's solar incentive programs for homes, businesses, and community solar projects past their previous end date of late 2027, though the details of the new programs still need to be worked out by state regulators, with implementation planned for 2028. The law also allows plug-in solar setups (small panels that connect directly to an outlet) and requires towns to speed up and simplify the approval process for residential solar installations. For homeowners, one notable change involves solar paired with battery storage. The law sets an $85 million annual spending cap across the residential, commercial, and community solar programs, but systems that include storage and are found to benefit all of the state's utility customers won't count against that cap. That carve-out could make battery-backed solar systems a more attractive option going forward. Some parts of the law are less favorable to solar development. Two towns, East Windsor and Enfield, got a one-year pause on new solar farms, and industry groups worry this signals that state rules could shift unpredictably. There's also broader uncertainty hanging over Connecticut's solar market: a major utility, Eversource, recently backed out of contracts for several large solar projects, citing unclear state policy direction, and turnover among state energy officials adds to the uncertainty. Homeowners considering solar may want to watch how state regulators shape the successor incentive programs over the next couple of years, since those details will determine what support looks like after 2027.
The 250-year history of U.S. energy consumption
The federal government's energy statistics office released a look back at how the country has powered itself over the past 250 years, and where things stand now. In 2025, the U.S. used 96 quadrillion BTUs of energy, up 2% from 2024 but still below the 2007 peak. Petroleum was the top energy source, with natural gas close behind. Renewables, coal, and nuclear each made up about 9% of total use. Altogether, fossil fuels still account for 82% of the energy the country consumes, even as their share has shrunk over time. The mix has shifted a lot in recent years. Renewables passed nuclear power in 2022 and passed coal in 2023, something that hadn't happened since the 1880s. Wind and solar now supply more energy than hydropower. Natural gas has become the top fuel for generating electricity and is also the most common way American homes are heated. None of this changes what's available to any single household, since that depends on local utilities and what's already installed in your home, but it does show the country's overall reliance on gas and electricity growing while coal keeps fading. Looking ahead, the report expects electricity demand to grow faster over the next couple of years than it has since 2000, driven mainly by data centers. Electric vehicles are also pulling more power off the grid: nearly 6 million EVs were on U.S. roads in 2024, six times as many as in 2018, and the electricity they use has grown sharply too. For homeowners, this is mostly background context on where the country's energy is headed, rather than something that changes any near-term decision about your own house.
Resilience from the ground up: The 2026 Impact Symposium
This news is about how local governments in the Washington, D.C. area are planning for climate resilience, not about a program homeowners can apply to directly. City officials from Baltimore, Arlington County, and Alexandria met to share how their sustainability certifications (a green-building rating system called LEED) have helped them prepare for problems like extreme heat and flooding. Baltimore, for example, runs "Resiliency Hubs" that connect neighborhoods with support and resources during emergencies. One detail that touches homeowners directly: Arlington County's flood-planning work has earned it a high rating in a federal program run by FEMA. That rating gives homeowners in the county's mapped flood zones a 10% discount on their National Flood Insurance Program premiums. If you own property in a flood zone in Arlington, this is worth knowing, since it can lower your flood insurance cost without you doing anything extra. Beyond that, the meeting mostly covered how cities finance and plan resilience projects, including efforts by the Montgomery County Green Bank to help local governments line up funding for sustainability work. There's no new homeowner program or deadline here, but it signals that more localities in the region are building out infrastructure and policy aimed at flooding, heat, and energy reliability. If your area is doing similar planning, it may be worth checking whether your city or county offers something similar, especially if you live in a flood-prone zone.
