EV sales are booming in Europe – and plunging in North America
Electric vehicle sales are moving in opposite directions on either side of the Atlantic. In Europe, EV sales jumped 36% in August compared with a year earlier, helped by purchase incentives, cheaper models, and higher gas prices in some countries. France, Germany, and the UK are leading that growth, with France hitting a record 41% EV market share. Spain also just completed its first full month of a new incentive program, offering up to €4,500 (about $5,190) toward a new electric car, with eligibility backdated to January 1. In North America, EV sales fell 33% year over year in August. Part of that drop reflects last year's rush to buy EVs before the federal tax credit expired on September 30, 2025, which makes this year's comparison look worse than it might otherwise. But supply is also a factor: automakers have canceled EV models and cut back availability in response to the less favorable US policy environment, so it isn't just a question of buyer demand drying up. In Canada, automakers have been using a quota of lower-tariff import permits for Chinese-built EVs, and unused permits have rolled over into a new allotment running through February 2027. None of this changes what's available for home energy upgrades, but it's a sign that EV incentives and model availability are shifting differently by region. If you're considering an EV alongside other home electrification plans, like a heat pump or panel upgrade, it may be worth checking what incentives currently exist in your area, since US federal support has weakened while several European countries have expanded theirs.
Activists from Across Indiana Demand State Leadership Reject Bailouts for Expensive Coal
In Indiana, activists delivered more than 1,300 petitions to Governor Mike Braun and Attorney General Todd Rokita, asking the state to challenge a Trump administration order forcing two coal-burning power units to keep running past their planned retirement. NIPSCO's Schahfer plant and Centerpoint's Culley plant were both supposed to shut down in December 2025, ending charges to customers for keeping them online. The federal order requires them to keep operating anyway. The dispute matters for utility bills. NIPSCO has asked to collect $38 million from customers for just the first three months of the forced restart, even though the Schahfer plant reportedly hasn't been able to generate power since the order took effect. Of that amount, $2.8 million is described as pure profit for the utility. Activists argue that Hoosiers, who already pay some of the highest energy rates in the state, shouldn't have to cover the cost of keeping an aging coal plant on standby. For homeowners in NIPSCO or Centerpoint territory, this is a sign that a coal-related charge tied to these plants may show up on bills rather than disappear as expected. Nothing has changed yet in terms of new fees, since this is a call for state officials to act, not a rate decision. But it's worth watching your utility bill and any rate case notices from NIPSCO or Centerpoint in the coming months, since costs tied to this order could eventually be passed through to customers.
Could Jackery EnergyGuard Max Lead A Shift To Large Capacity Home Batteries?
Jackery showed off a new whole-home battery system, the EnergyGuard Max, at a trade show in Berlin. It pairs a 100 kWh battery (much bigger than a typical home battery, like a Tesla Powerwall) with a large inverter, all built for outdoor use. For comparison, a US home uses about 29 kWh a day on average, so a battery this size could keep a home running for days, or longer if you cut back on use, during a long power outage. It could also help avoid high electricity prices during heat waves or cold snaps, if your utility charges more at peak times. The system's inverter can also handle very fast EV charging and two-way charging, meaning a car's battery could someday help power the home, or vice versa. It includes several layers of safety protections against surges, short circuits, and other faults. It can also take in more solar power than most home systems use, which could matter for homeowners looking to add rooftop solar alongside a battery. Beyond backup power, a battery this size could reduce the peak power a home draws from the grid, which matters for older houses whose electrical wiring struggles to support new demands like heat pumps, EV charging, or added air conditioning. The system is designed for the European market for now, with no US pricing or timeline given. The company suggests it should cost less than an average new car, but exact numbers aren't available. Whether this size of battery makes financial sense for a US home would depend on local electricity rates and whether the homeowner could sell stored power back to the grid.
Ask a Scientist: How Can We Make Sure Environmental Rules Work in the Real World?
Homeowners often deal with more than one source of pollution at a time — traffic exhaust, contaminated tap water, industrial emissions nearby — but environmental rules usually judge each pollutant separately instead of looking at the combined effect on health. This approach, called cumulative impacts analysis, tries to fix that by pulling in health data, pollution maps, and information about a community's living conditions before permits or regulations get decided. In late 2024, the EPA released a framework meant to build this approach into its work and asked for public comment. Under the Trump administration, that process stalled: the agency eliminated the offices that developed the framework, disbanded its advisory councils, and never responded to the comments it collected. The Union of Concerned Scientists reviewed those public comments and released its own report, arguing that cumulative impacts analysis works when it comes with real enforcement, includes input from health workers and people affected in their own workplaces and neighborhoods, and treats community experience as seriously as lab data. With federal action stalled, the report points to states and localities as the places where this can still move forward. At least seven states already have cumulative impacts laws or regulations, mostly used in air pollution permitting, and some cities have their own rules too. If your state or city is one of them, it could mean more scrutiny of new industrial or pollution sources near where you live. Where it isn't, this is the kind of policy that community groups and local governments may push for next, using this report as a resource.
Kia reveals EV3 lease offer for $349 a month, but there’s a catch
Kia's new electric SUV, the EV3, is now for sale in the US starting at $29,890, making it one of the cheaper EVs on the market. It comes in five trims with two battery options, offering EPA-estimated range from 221 miles up to 321 miles. All versions include a NACS charging port, which lets drivers plug into Tesla Superchargers without needing an adapter. For homeowners weighing whether an EV fits their household, the lease terms matter more than the sticker price. Kia is advertising a $349-a-month lease, but that rate applies only to the EV3 Wind FWD trim, and it requires $3,999 due at signing over a 24-month term. Factoring in that upfront cost, the effective monthly cost works out closer to $515. An all-wheel-drive version of the same trim leases for $399 a month, also with $3,999 due at signing. The base $29,890 Light trim, the cheapest EV3, does not currently have any lease offer available. Kia is also offering 0.90% APR financing for up to 48 months for buyers who'd rather purchase than lease. If you're comparing this to other affordable EVs, the EV3 Wind FWD's effective lease cost is still lower than a comparable Chevy Bolt lease, which works out to around $561 a month once its own signing fee is included. For anyone thinking about home charging setup costs alongside a new EV, the range and charging speed are worth noting: the smaller battery charges from 10% to 80% in about 29 minutes, and the larger one takes about 31 minutes on a fast charger.
Is the West on the cusp of a transmission breakthrough?
Western states are trying to speed up construction of long-distance power lines that move electricity across the region — a process that has historically taken decades. One example: a transmission line connecting Idaho and Nevada was first proposed 30 years ago and only broke ground on its final segment this month, with completion expected in 2028. Building these lines in the West is especially slow because so much land is federal, which triggers many separate permitting reviews, and because the region has no single grid operator (California is the exception). With electricity demand rising fast from data centers, factories, and population growth, Western governors, utilities, and power developers are now working on their own coordination efforts rather than waiting on Congress. A group of utilities and power producers recently completed the first region-wide study of transmission needs, finding more than 12,600 miles of new or upgraded lines are needed over the next decade. Twelve governors have also formed a task force to align permitting rules across states so companies don't have to navigate each state's process separately. The Bonneville Power Administration, which controls most transmission in the Pacific Northwest, has also signed on to support these efforts after adding little new capacity for decades. None of this guarantees faster construction — federal environmental reviews remain slow and prone to legal challenges, and one project, a Utah-to-Nevada line called SilverRock, will be an early test of whether the new coordination actually works. For homeowners, more regional transmission could eventually mean more reliable power and access to cheaper solar, wind, and geothermal electricity, though any benefits are years away.
Almost Dead Silence on Electric Vehicles from Automakers in USA
Traditional car makers in the US have gone mostly quiet on electric vehicles. For a few years, companies like Ford, GM, and others put out a steady stream of press releases touting their EV plans, even though electric cars made up a small share of what they actually sold. That marketing push has largely dried up. One view is that automakers leaned into EV hype to boost their stock prices, but investors never rewarded them the way they've rewarded Tesla, which still accounts for roughly half of all EV sales in the US. With EVs now a political target under the Trump administration, some automakers appear to have decided it's safer to stay silent or pull back rather than promote electric models. Ford is a partial exception. It killed its F-150 Lightning electric pickup and canceled billions of dollars in EV investment, but it's now promoting a new "Universal EV" project. Beyond that, though, there's little EV news coming out of Detroit or other US automakers these days, especially compared to the near-daily EV announcements coming from Chinese manufacturers. For homeowners, this doesn't change anything about home energy upgrades or rebates directly. But if you're weighing whether to add an EV and charger to your home energy plans, it's a reminder that new electric models and pricing from mainstream US brands may arrive more slowly than expected, even as EV technology keeps advancing elsewhere.
New electrode design by German institutes increases battery energy density by up to 15%
Researchers in Germany, led by the Fraunhofer Institute for Solar Energy Systems, have developed a new battery electrode design that could pack 10% to 15% more energy into a battery cell without making it heavier. They tested the approach in lithium-ion, sodium-ion, and zinc-ion batteries, and built working prototypes using lithium-ion pouch cells (a flexible, foil-wrapped battery format common in electronics and storage systems). The trick is making the electrode coating much thicker than usual, up to 800 micrometers versus the typical 100 to 200. That means fewer internal metal layers (current collectors) are needed, freeing up space and weight for the material that actually stores energy. The design is also PFAS-free, avoiding the "forever chemicals" often used in battery manufacturing, and skips toxic solvents in production. Researchers say the manufacturing process is simpler and cheaper than current wet-coating methods, which could make it easier for smaller companies to build battery plants. For homeowners, this isn't a product you can buy yet. It's early-stage research aimed at improving stationary battery storage, the kind of home battery system that stores solar power or helps manage electricity use during peak hours. If the technology moves into commercial production, it could eventually mean more efficient, less expensive, and more environmentally friendly home batteries. For now, there's no timeline for when or if this design will reach the market, so it's worth watching rather than acting on.
A-Gas Adds Third AHRI-Certified Lab in North America
Refrigerant company A-Gas International has earned certification from the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) for its lab in Dartmouth, Nova Scotia, making it the only AHRI-certified refrigerant testing lab in Canada. The facility came to A-Gas through its March acquisition of Refrigerant Services Inc. and joins two other AHRI-certified A-Gas labs in North America, located in Rhome, Texas, and Bowling Green, Ohio. The certification means the Dartmouth lab meets AHRI Standard 700, which sets purity and quality benchmarks for reclaimed refrigerants, including older types like CFCs and HCFCs as well as newer ones like HFOs and A2Ls. For businesses in Canada that need refrigerant tested or reclaimed, having a certified lab on home soil means faster turnaround, lower shipping costs, and less customs paperwork, since samples no longer need to cross the border into the U.S. A-Gas also runs a second Canadian lab in Stoney Creek, Ontario, that follows the same technical standards but has not received formal AHRI certification. This is mainly a business and industry development rather than something that changes homeowner rebates or costs directly. If your home has central air conditioning, a heat pump, or refrigeration equipment serviced with reclaimed refrigerant, this kind of certification helps ensure the refrigerant used or recovered during that service meets recognized purity standards. For most homeowners, though, the news is background: it signals that refrigerant testing and reclamation infrastructure in Canada is expanding, which can support smoother, more reliable servicing over time.
Volvo kills off another EV for the US, but it has a replacement coming in 2027
Volvo is dropping the EX40 electric SUV from its US lineup after the 2027 model year. This follows the earlier discontinuation of the smaller, cheaper EX30. With both gone, Volvo's least expensive electric vehicle in the US becomes the EX60, an SUV starting around $60,000. The EX40 had started at about $56,545, so this is a real jump for anyone shopping Volvo's electric lineup on a budget. Volvo does have a replacement planned. A new electric crossover called the EX50 is expected to launch by the end of 2027, with a starting price under $50,000. It will share its underlying platform with the EX60, which should mean improvements like longer driving range and faster charging compared to the outgoing EX40. Volvo has filed trademark paperwork confirming the EX50 name and that it will be electric, though full details haven't been released. For homeowners weighing an EV purchase alongside home charging plans, this means Volvo's lower-priced electric options are shrinking for the next year or so, with the cheapest current model priced near $60,000. If you were counting on a sub-$40,000 Volvo EV, that's not on the table now or evidently anytime soon — the company's earlier promise of a $35,000 EX30 never materialized in the US. The EX60 does come with faster charging capability and access to Tesla's Supercharger network without an adapter, which could matter if you're planning home or public charging setups around a new EV purchase.
Beyond Category 5: What extreme hurricanes mean for electric utilities
Hurricanes are getting more extreme, and some scientists want to add a Category 6 to the scale used to rate storm strength, which currently tops out at Category 5. The idea followed Hurricane Melissa, which hit Jamaica in October 2025 with sustained winds of 185 mph. But experts note that the category system only measures wind speed. It misses other things that make storms destructive, like size, rainfall, and storm surge (flooding pushed inland by the storm). Superstorm Sandy in 2012 was only a Category 3 but caused catastrophic damage because of its size and flooding. For the electric grid, this matters more than the label itself. Power companies have historically planned for storms based on past patterns, but experts argue that approach is falling behind as storm risks shift and intensify. Even areas that don't typically see hurricanes, like Southern California, could face elevated storm risk this year due to El Niño weather patterns combined with unusual ocean warming. That combination could push strong storms farther north than usual, raising risk for the southwestern U.S. and northwestern Mexico too. For homeowners, the takeaway is less about hurricane categories and more about what they signal: the conditions that cause prolonged power outages, like flooding and grid damage, are becoming less predictable and potentially more severe than in the past, including in places without a long history of major storms. This is a broader trend in how utilities plan for and respond to extreme weather, not a specific program or deadline tied to any one home.
Coal-to-solar project lands a rare clean-energy win in Ohio
Ohio regulators have approved a large solar-plus-battery project in Vinton County, in the southeast part of the state, with no opposition — unusual for a state where clean energy proposals often face pushback. Developer Recurrent Energy will build 149 megawatts of solar and 149 megawatts of battery storage on reclaimed coal mine land at the Hamden Energy site. Because the project sits on a former mine rather than farmland, it avoided the land-use fights that have slowed other Ohio solar projects. Construction will start only after ongoing land reclamation work, handled separately by another company, is finished. This is part of a broader shift in the state. A 2025 law, House Bill 15, lets former mine lands and industrial sites known as brownfields count as priority areas for energy development, and lets counties host solar there even under a 2021 law that otherwise makes it easier for local governments to block wind and solar projects. Ohio has identified more than 70,000 acres that could potentially qualify, and state officials have begun designating the first such sites. None of this changes anything for a typical homeowner's rooftop or utility bill directly, but it signals more large-scale solar and storage projects may get built on old industrial and mining land in Ohio going forward, rather than farmland. A separate bill that could make future wind and solar permitting harder statewide has passed the Ohio Senate and is now before the House.
China exported more cars in 8 months than in all of 2025 – and most are EVs
China is exporting cars, especially electric ones, at a record pace. Through August, the country had already shipped 6.2 million passenger vehicles this year, topping its entire 2025 total of 6.1 million, with four months still left to count. Electric and plug-in hybrid vehicles made up 58.4% of those exports in August, and their volume grew 154.7% from a year earlier. If the pace holds, China could end the year having exported more electric vehicles alone than any other country exports cars of any kind. This isn't really a homeowner story in the direct sense, but it does say something about where the electric car market is headed globally. Chinese automakers are selling large numbers of affordable EVs abroad while other countries, including the US, have pulled back on EV manufacturing incentives. That shift affects what electric vehicles are available and how they're priced in different markets, which matters if you're thinking about pairing a future EV purchase with home solar or a home charger. For most homeowners, the immediate takeaway is limited: this is about global car manufacturing and trade, not a new program, rebate, or deadline that touches your house. If you already have an EV or are planning one, it's worth keeping an eye on how these shifts affect vehicle prices and availability in your own country over the next year or two.
Continuing post-Labor Day Green Deals hub – EVs, power stations, tools, smart devices, more [Updated]
This roundup covers a Labor Day sale event with discounts across electric bikes, portable power stations, solar gear, tools, and smart home devices. Many of the deals started before the holiday and continue past it, with some ending the same night and others running through the week or longer. There isn't a single fixed deadline for everything. Tool discounts in particular don't have set end times, so prices in that category may change without much notice. For a homeowner weighing energy upgrades, this kind of sale is worth a look mainly for items like portable power stations and solar equipment, which can serve as backup power or a smaller step toward home energy independence, alongside smart home devices that can help with energy monitoring or automation. None of this is tied to any government rebate program or utility incentive. It's a retail sale, so any savings come directly from the discount price, not from a rebate application. If you were already considering one of these categories, this is a moment to compare current prices, but there's no broader policy or program news here that changes what's available to homeowners beyond the sale itself.
7 steps toward a future-friendly EPR strategy
This is business and policy news about how companies handle packaging regulations, and it does not touch on home energy upgrades or rebates. It has no direct bearing on your house, your utility bills, or any weatherization or heat pump project you might be planning. The piece is aimed at manufacturers dealing with extended producer responsibility (EPR) rules, which are state laws that make companies pay fees based on the packaging and materials they use, and sometimes require them to include recycled content or cut down on plastic. States including California have been rolling out these programs, and companies are figuring out how much they will owe and how to redesign products to lower those costs. Suggested steps include gathering data on materials and weight, calculating fee exposure, and looking at ways to reduce packaging altogether, such as reuse and refill systems, eliminating unnecessary materials, or switching to non-plastic alternatives. None of this changes what rebates or incentives are available for insulation, air sealing (sealing gaps that leak heated or cooled air), heat pumps, or other home upgrades. If you are researching those options, this news is unrelated to that process.
AI predicts wind-uplift resistance of solar PV piles
Researchers in Iran have built an AI tool that predicts how well steel piles will hold down large solar panel arrays against wind. This is a research development for utility-scale solar farms, not home rooftop systems, so it does not directly change anything for a homeowner's own property. The problem the researchers are tackling: ground-mounted solar panels catch a lot of wind but don't weigh much, so strong wind can actually try to lift or tip the whole structure. The steel piles driven into the ground have to resist that uplift. In soft, loose, or wet soil, figuring out whether a pile will hold is tricky, and standard engineering formulas often get it wrong, leading to designs that are either overbuilt (more expensive) or risky. To improve on this, the team tested 130 steel piles at a solar site in Rafsanjan, Iran, measuring how fast each pile was driven into the ground, the soil's friction properties, and how much pulling force it took to shift the pile. They fed this data into a neural network (a type of AI model) that could predict a pile's holding strength from installation data alone. The model performed reasonably well and found that how fast a pile is driven and the soil's friction angle matter most, more than the pile's length or surface area. The researchers caution that their model was trained on one sandy site and may not work for different soil types like clay or gravel elsewhere. For homeowners, this is background engineering research aimed at making large solar installations more reliable and cost-effective, with no direct bearing on home energy upgrades or rebates.
SOL Components issued patent for mounting rail used on solar trackers
Solar tracker maker SOL Components was granted a U.S. patent for a mounting device called QuickGrip, used to attach solar panels to the metal rails on single-axis trackers (the systems that tilt panels to follow the sun across the sky). The patent, issued September 1, covers a method for clipping panel frames onto rails using an indexing flange, a design meant to speed up installation. SOL Components makes two tracker models and a fixed-tilt racking system, and the company was acquired in June by Create Energy, which now offers SOL's products through its own project design platform. For a homeowner, this is a piece of industry news about equipment used mostly in large, ground-mounted solar arrays rather than typical rooftop residential systems. It doesn't come with any rebate, incentive, or program change that would affect your own home upgrade plans. The patent is really about a company protecting its engineering design and marketing it as faster and more reliable for utility-scale or commercial solar projects. If you're weighing a home solar or energy upgrade, this news doesn't change your options or costs directly. It's worth knowing only as a sign that solar hardware companies keep refining mounting and installation equipment, which over time can filter down into lower costs and faster installs across the industry, including for smaller residential solar setups.
Create Energy subsidiary SOL Components secures patent for QuickGrip solar mounting rail
A Tennessee solar equipment company, Create Energy, has patented a new mounting system for large solar installations that use tracking systems (structures that tilt panels to follow the sun through the day). The part, called QuickGrip, is a rail that attaches solar panels to the tracker's tube. Its design lets brackets unfold on site without tools and lock into place with a single bolt, instead of the multiple bolts and hardware pieces usually needed. The rail also has built-in tabs that hold panels in position before they're fully fastened down. This is not something a homeowner would install — it's aimed at utility-scale and commercial solar projects that use ground-mounted tracking systems, not the fixed rooftop panels typical of home solar. Create Energy says the design can cut installation time for trackers and related wiring components by up to half when paired with its own wiring system. The practical upshit for homeowners is indirect: faster, cheaper installation methods for large solar farms can eventually help lower the cost of the electricity those farms sell to the grid, but this patent doesn't affect home solar equipment, rebates, or installation costs directly. The technology comes from SOL Components, a company Create Energy acquired in June 2026, which is now being folded into Create Energy's broader lineup of solar hardware for developers.
Research Suggests Auto Loans Should Account for Vehicle Efficiency
A new report from Atlas Public Policy finds that drivers who buy more fuel-efficient vehicles are less likely to default on their auto loans, yet electric vehicle buyers often pay higher interest rates than buyers of gas-heavy vehicles. Looking at loans while accounting for credit score, income, and other standard factors, the report found that people financing below-average fuel economy vehicles are 16 percent more likely to default than average. Buyers of hybrids and plug-in hybrids are 16 percent less likely to default, and EV buyers are 50 percent less likely to default than the average borrower. Despite this lower risk, EV buyers consistently get charged higher loan rates than buyers of less efficient vehicles, a gap that grows wider for lower-income borrowers. The report estimates this costs EV buyers an extra $300 to $350 over a typical 72-month loan, compared to average rates, not even counting the lower rates their actual risk level would justify. For a homeowner also weighing a vehicle purchase alongside home energy upgrades, the practical takeaway is that fuel-efficient and electric vehicles cost less to own and, according to this research, come with lower default risk than lenders currently price in. The report argues that auto lenders, including the financing arms of automakers like Ford Credit, GM Financial, and Toyota Financial Services, could adjust loan terms to reflect this lower risk, which would make efficient vehicles more affordable to finance while also reducing losses for lenders.
First-of-a-kind label focuses on compact products
There's a new label to look for on laundry and skin care products: "Certified Compact Product." It comes from NSF, the same group behind many product safety standards, and it marks items that pack more use into less material. For laundry tablets, that means a single dose has to weigh 20 grams or less and still get a full load clean. The idea is that smaller, more concentrated products mean less packaging, less water used in manufacturing, and lower shipping emissions, since companies aren't hauling around water-heavy formulas. The certification launched last month and several familiar brands are already working through the approval process, though NSF hasn't named them yet. Right now it only applies to laundry and skin care items, but shampoo and conditioner are next in line. If you shop on Amazon, products with this certification will also carry the retailer's "Climate Pledge Friendly" tag, which covers items meeting any of more than 50 environmental standards. For a homeowner, this doesn't change anything about your house or energy bills, but it may show up next time you're buying detergent or skin care and want a quicker way to spot products that use less packaging and resources. Keep in mind this joins a long list of existing "ecolabels," so it's one more option rather than a universal standard.
September 2026: The ACHR NEWS Celebrates a Century
A trade publication that covers the heating, cooling, and refrigeration industry, ACHR NEWS, is marking its 100th anniversary. It started in 1926 under the name Electric Refrigeration News and has tracked the industry's changes ever since, from early electric refrigeration and air conditioning through today's heat pumps, newer refrigerants, and electrification push. This is an industry milestone story rather than news about a specific program, technology, or rebate. There is no new rule, deadline, or product here that affects your house directly. It is worth knowing only as context: the outlet reporting on heat pump technology, refrigerant changes, and HVAC trends has been doing so for a century, which is part of why its coverage of things like electrification and A2L refrigerants (a newer class of lower-impact refrigerants replacing older ones) carries some weight in the trade. If you're weighing an upgrade to your home's heating or cooling system, this anniversary itself doesn't change your options or costs. But it's a reminder that the technology is shifting fast right now — heat pumps and refrigerant standards are two areas seeing real change industry-wide — so it may be worth checking current state and federal rebate programs when you're ready to plan a project, since what's available can vary by location and change from year to year.
Japan’s Idemitsu sets up U.S. lab for space-grade CIGS solar cells
Japanese energy company Idemitsu Kosan has opened a research lab at the University of California, Santa Barbara to develop solar cells built for spacecraft, not homes. The cells use a technology called CIGS (copper indium gallium-selenide), a thin-film solar material different from the silicon panels typically installed on rooftops. Idemitsu says this is the first lab of its kind and will let it test and refine these space-grade cells based on U.S. market needs, feeding what it learns back into product development in Japan. The company is also building a smaller-scale manufacturing plant in Japan, aiming to work out mass-production methods by 2027, before deciding whether to scale up to full commercial production. This effort builds on a deal Idemitsu struck last year with U.S.-based Source Energy Company to make CIGS solar modules for satellites, which the company says hold up well against radiation, weigh less, and keep performing steadily, potentially letting satellites use smaller solar arrays. Idemitsu has worked with this thin-film technology for years; it became the largest shareholder in Solar Frontier, a Japanese CIS module maker, back in 2019. None of this involves residential solar equipment or upgrades. It is aimed at the satellite and space industry, and there is no indication yet that this cell technology is headed toward home solar installations or rebate programs. For homeowners tracking solar options, standard rooftop panels remain the relevant technology for now.
Rocket Lab launches lightweight space solar cell built without critical minerals
This is a space industry story, not a home energy one. Rocket Lab has released a new solar cell for satellites, called IMM Apex, that skips germanium, a material long used as a base layer in space solar panels. Germanium supplies have gotten more expensive and harder to secure because of export controls and mineral shortages, so this cell is meant to sidestep that problem. The new cell converts 31.5 percent of sunlight into power at the start of its life and weighs 40 percent less than older versions. That lighter weight matters for satellites because less weight means cheaper launches. Rocket Lab designed it to swap in for existing germanium-based cells without requiring satellite makers to redesign their equipment. The company is ramping up production at a facility in Albuquerque, New Mexico, aiming for large-scale output to supply satellite constellations, space agencies, and national security programs. None of this involves home solar panels, rebates, or residential energy equipment. It is a development in satellite technology and the materials used to build spacecraft power systems. There is nothing here that changes what is available for home energy upgrades or what a homeowner might qualify for.
What the 2026 ETS Review Means for Transport
This is a policy story out of Europe, not something that changes any homeowner's project this week, but it's worth understanding if you follow energy costs. The EU is reviewing its carbon pricing system for power plants, industry, and transport, called the EU ETS (Emissions Trading System). Since 2005, the system has cut emissions from covered sectors by about half by making polluters pay for carbon, and it has raised more than €230 billion along the way. The current proposal focuses on aviation. Right now, long-haul flights escape carbon pricing entirely, so more than half of Europe's aviation emissions go unpriced. The new plan would extend pricing to flights departing Europe for airports within 5,000 kilometers of Frankfurt — covering trips like Paris to Dubai, but not Paris to New York or flights to China. That would raise the share of priced aviation emissions from 44% to about 59%, though credits for sustainable aviation fuel would trim the real number to 57%. Private jets would also face a carbon price for the first time, and airlines that avoid creating warming contrails could earn free pollution allowances. None of this changes rebates, appliances, or upgrades for a house. But it does reflect a broader push in Europe to keep raising the cost of fossil fuels and reward cleaner choices — the same logic behind incentives for heat pumps and electrification here. It's a reminder that carbon pricing and clean-energy policy keep evolving well beyond home improvement programs.
Elon Musk’s Boring Company raises $3B at $23B valuation, led by UAE
This one is not about home energy upgrades. Elon Musk's Boring Company, the tunneling venture behind the Las Vegas Loop, just closed a $3 billion funding round led by the United Arab Emirates, putting the company's value at $23 billion, up from about $5.7 billion in 2022. Other investors include Sequoia Capital, Andreessen Horowitz, Temasek, and several others. The UAE is both funding the round and is the customer for the company's biggest project: a commitment to build more than 150 kilometers of tunnel in the UAE, on top of a 6.4-km pilot Loop already planned for Dubai. The only place riders can actually use a Boring Company tunnel today is Las Vegas, where the Vegas Loop has carried more than four million passengers using human-driven Teslas. The company also just started tunneling in Nashville and has a long history of announced projects in cities like Chicago, Baltimore, Los Angeles, San Antonio, and Fort Lauderdale that were canceled or quietly dropped. None of this affects home energy costs, rebates, or upgrades directly. If you drive an electric vehicle, charging it from home solar remains one of the more reliable ways to lower fueling costs, regardless of how this tunneling venture plays out.
Lessons from India’s Transition to Electric Vehicles
This is a policy story out of India, not something that changes what's available to homeowners here, but it's a useful look at how electric vehicle adoption picks up speed. Electric vehicles now make up 8.25 percent of new vehicle sales in India, up from 7.48 percent the year before, out of more than 449 million vehicles on the road. The gains trace back to national incentive programs that lowered costs for manufacturers and buyers, but the real differences show up state by state. Some states built manufacturing capacity first and waited for buyers to follow, with mixed results. Others saw demand come first, from taxis, delivery vehicles, and everyday buyers responding to fuel costs, which then drew factories in after the fact. Delhi took a third path: rather than relying on subsidies, it set firm mandates and deadlines for phasing out gas-powered vehicles, which pushed adoption forward on its own. The states pulling furthest ahead didn't rely on just one approach. They combined manufacturing investment, buyer incentives, and clear regulatory timelines together. For a homeowner, none of this changes any rebate or program you can access today. But it's a sign of where EV costs, battery manufacturing, and charging infrastructure are heading globally, since a bigger EV market in a country like India can affect battery supply chains and prices worldwide over time.
Hyundai Motor Group and African Development Bank Partner to Accelerate Sustainable Development Across Africa
Hyundai Motor Group and the African Development Bank have signed an agreement to work together on sustainable development projects across Africa. The deal, signed in Seoul, pairs Hyundai's expertise in vehicles, energy, and infrastructure with the bank's ability to finance large projects. The two organizations plan to focus on six areas: clean energy (including green hydrogen), local transportation solutions, roads and infrastructure, building out electric vehicle supply chains, manufacturing capacity, and workforce training. This is a broad partnership agreement rather than a specific product launch or funding program, so there's no immediate program or rebate tied to it. The companies say they'll identify specific investment projects and financing structures in the coming months, but no timelines, dollar amounts, or details on individual projects were announced. For homeowners, this news doesn't have any direct bearing on your house, your energy bills, or available incentives. It's a business and infrastructure story about corporate and international development strategy in Africa, not about residential energy upgrades, appliances, or rebate programs in the U.S. or elsewhere. If Hyundai's clean energy or EV work eventually leads to new products or technology reaching consumer markets, that would be a separate development to watch for down the road.
Volvo Updates the XC40 & EX40 with Longer Range and Updated Aesthetics
This is car news rather than home upgrade news, but it touches on home charging. Volvo has updated its XC40 and electric EX40 models with new looks and bigger batteries. The plug-in hybrid XC40 now gets an estimated 78 miles of electric-only range per charge, up from 35 miles in the previous version, along with a stronger electric motor. That means someone who plugs in regularly at home could cover two or three days of typical driving before needing gas at all. The fully electric EX40 gets a long-range version with 357 miles of range on a larger battery, plus faster charging speeds. However, Volvo is not bringing the EX40, or the smaller EX30, to the US market right now, a decision tied to the current administration's less supportive stance on EVs. So US buyers won't have access to that fully electric option, though the plug-in hybrid XC40 with its longer electric range should still be sold here. For homeowners thinking about home charging, the takeaway is that plug-in hybrids like the updated XC40 are increasingly capable of running mostly on electricity for day-to-day driving, as long as you can plug in at home, at work, or even just at a standard outlet. That makes a home charging setup more useful even if you're not ready to go fully electric. The vehicles also come with updated safety sensors and driver-assist features, but those are separate from any home energy considerations.
Are New Electric Entrants Serious Competition for European Truckmakers?
New companies like Tesla, BYD, and SuperPanther are pushing into Europe's electric heavy truck market, and a new analysis says they're real competition for the continent's longtime truck manufacturers. Buying an electric truck from one of these new entrants costs about 12% less over the life of the truck compared to an equivalent model from an established European maker, while performing about as well on key measures. These new companies are aiming to capture more than a quarter of the electric truck market by 2030, based on their own stated production and export plans. This story is about the commercial trucking industry, not household equipment, so it has no direct bearing on home energy upgrades. But it's a sign of how fast electric vehicle technology is spreading into heavy-duty uses that used to seem out of reach for battery power, and how price competition is starting to bring costs down across the board. The analysis also notes that European truckmakers will need to speed up their own shift to electric models to keep up, which depends partly on emissions rules for trucks staying in place rather than being loosened. For homeowners, the direct takeaway is limited: this is industry-level news about freight and manufacturing, not a program or rebate you can use on your house. If you're tracking electric vehicle costs generally, it's a data point that battery-powered trucks are getting cheaper to own, even as that trend plays out in commercial fleets rather than driveways.
The NRC is Regulating Nuclear Security like it’s September 10, 2001—And We Should All Be Concerned
The Nuclear Regulatory Commission is rolling back security rules put in place after the September 11 attacks, according to a longtime nuclear safety analyst. After 9/11, Congress required the NRC to run its own mock attack drills at power plants every three years — tests where security teams defend against simulated terrorists trying to trigger a meltdown. Those drills, called force-on-force inspections, showed real weaknesses over the years and pushed plants to improve. Starting in 2028, the NRC plans to let plant owners run and grade these drills themselves, with the agency only observing. The commission has also cut routine security and cybersecurity inspection resources by more than half in some cases, shifted inspection duties to staff without security training, allowed some new reactor owners to rely on local police instead of their own security forces, and eliminated the office created after 9/11 to oversee nuclear security. A newly proposed rule would also redefine what counts as a security failure, so that even an attack causing a meltdown as severe as Three Mile Island might not officially count as "radiological sabotage" if public radiation exposure stayed under certain limits. None of this requires homeowners to do anything, but it matters if you live near a nuclear plant or if new small reactors get built in more populated areas, as the industry is now planning. Weaker independent testing and oversight mean less outside verification that a plant's security force could actually stop a real attack, at a time when threats like drones and AI-assisted cyberattacks are becoming more sophisticated.
Congressman presses DOT on Tesla FSD after 43 sleeping-driver videos
This story is about car safety, not home energy upgrades, but here's the gist. A US congressman, Rep. Raja Krishnamoorthi, has given the Department of Transportation until September 30 to answer questions about Tesla's Autopilot and Full Self-Driving (FSD) systems after an NBC News investigation found 43 videos of drivers who appear to be asleep while the cars were moving. Tesla itself says these systems require a driver to stay alert and are not fully autonomous. The letter connects those videos to a federal safety investigation already underway. Highway safety regulators (NHTSA) are examining roughly 3.2 million Teslas equipped with FSD, in a probe that's one step short of a possible recall. That investigation has already tied nine incidents, including one death, to the system. The congressman also criticized a message Tesla's cars show when drowsiness is detected — "Stay focused with FSD" — arguing it encourages continued use rather than telling the driver to stop. Owners have reportedly found simple ways to fool the car's driver-monitoring camera, such as covering it or wearing sunglasses. The letter asks regulators what they know about this, how well the monitoring actually works, and what evidence would be enough to trigger a recall. This has no direct bearing on home energy projects, but it's a reminder that any EV you might charge from solar or home power comes with separate, ongoing safety questions about its driver-assist features.
Electric car sales doubled in Russia after Ukraine blew up oil refineries
Electric car sales in Russia have more than doubled this year, after Ukrainian strikes knocked out a large share of the country's oil refineries. From June through August, Russians bought 26,543 battery-electric and plug-in hybrid vehicles, up 118% from 12,187 in the same period last year. The jump comes as Russia's refining capacity has dropped to about 70% of what the country needs, with 24 of its 33 largest refineries hit. That has led to long lines at gas stations, fuel-sale restrictions in several regions, and a ban on gasoline exports. Even with the surge, electric vehicles still make up only about 6% of the roughly 400,000 cars sold in Russia during that stretch, well below the global average of around 25%. Russia has long had cheap, abundant gasoline, which is part of why electric cars never caught on there. The current spike shows that even a country built around oil can shift toward electric vehicles when gas becomes hard to find. For homeowners, this is really a story about global energy trends rather than anything that changes rebates or programs close to home. It is a reminder that fuel supply disruptions elsewhere in the world can ripple into gas prices and push more drivers everywhere toward electric options. If you already have an EV, or are weighing one alongside home upgrades like a heat pump or rooftop solar, this is one more sign that the shift away from gasoline is picking up speed even in unlikely places.
Nanrobot LS7+ review: This 70 mph electric scooter is absolutely insane
This one isn't for Retrofit Relay's usual territory of insulation and heat pumps, but here's the gist: it's a review of a very fast, very powerful electric scooter called the Nanrobot LS7+, priced at $2,299. The scooter has two motors totaling 6,000 watts of power (with brief bursts up to 10,000 watts) and a claimed top speed of about 74.5 mph, though the maker says real-world riding tops out closer to 58-65 mph. It weighs about 119 pounds, so it's not something you'd carry up stairs, and it's built more like a small electric motorcycle than a typical commuter scooter. It comes with hydraulic suspension, hydraulic brakes, and a steering damper to help keep it stable at speed. A large battery (2.52 kWh) gives a claimed range up to 81 miles, though that number drops fast if you actually use the scooter's speed and power. The reviewer is blunt that this is not a beginner scooter and is probably more machine than most riders need. Depending on where you live, a scooter this fast may not even be legal to ride on public roads, so anyone curious would need to check local rules. The reviewer suggests it makes more sense as an off-road recreational vehicle for experienced riders with private property than as a everyday commuter option.
Segway Myon e-bike + $150 FREE accessory credit $1,800 ($350 off), EcoFlow 50% off power station sale, Anker security, more
This roundup covers a batch of deals on gear that can touch your home's energy and security setup, though it's mostly consumer gadgets rather than efficiency upgrades. Segway is running a back-to-school e-bike sale that includes a free $150 accessory credit with its Myon Smart Electric Bike, now priced at $1,800 (a $350 discount), plus other e-bike markdowns. EcoFlow has a Home Preparedness Month sale with portable power station deals starting at $299, along with a bonus discount code, as part of ongoing Labor Day pricing. These battery power stations can serve as backup power for a home, though the sale itself is about pricing, not new technology. Separately, EcoFlow has a 48-hour flash sale on higher-capacity Delta 3 Ultra power stations that is ending soon. Other deals include Anker's eufy E50 security camera systems (with 2TB or 4TB storage) at up to $300 off, a 50 percent markdown on a Worx 20V cordless pole hedge trimmer, a discounted Greenworks string trimmer, a DEWALT oscillating tool kit, and a pro-grade 60V battery. There's also a $595 discount on Yozma electric mini dirt bikes. None of this is tied to specific rebate programs or efficiency incentives — it's retail pricing on e-bikes, backup power equipment, security cameras, and yard tools. If you're weighing a portable power station for outages or backup, or an e-bike for errands, these are simply temporary price drops rather than programs affecting your home's energy setup long-term.
Volkswagen ID. Buzz gains a new rear view camera system and more for 2027
This news is about a car, not a home energy upgrade, so it falls outside what Retrofit Relay usually covers. Still, here's what happened: Volkswagen is updating its driver-assist technology, called IQ.Drive, across several 2027 models, including the electric ID. Buzz van, the Atlas, Golf, and Tiguan. The changes include a rear view camera that can detect pedestrians, a feature that lets drivers start a lane change just by using the turn signal, and an "Emergency Assist Plus" that can steer the car to the side of the road if it senses a medical emergency. Cruise control software is also getting smoother. The ID. Buzz, an electric van, is returning for 2027 after skipping the 2026 model year. It now comes with a new "Tourer" version built for overnight camping trips, updated infotainment, and an optional data service called Road Experience Management, which uses camera data from other drivers to improve lane centering and speed accuracy in low-visibility conditions. That service comes with a one-year free trial. Volkswagen has not announced pricing for the 2027 ID. Buzz; the outgoing 2025 model starts at $59,995. None of this affects home electricity use, insulation, or rebate programs. If you're weighing an EV purchase alongside home upgrades like a heat pump or a home charger, this is worth knowing only as background on what's changing with one manufacturer's electric van lineup.
Toyota recalls 8,521 electric C-HR SUVs [Update]
Toyota is recalling 8,521 of its electric C-HR SUVs because of a software error that can cause the vehicle to suddenly lose power while driving. The problem lies in the software that controls the vehicle's electric drive control unit (ECU), which is supposed to limit how much the battery charges. Under certain conditions — such as when the battery is already full or nearly full and the driver keeps using regenerative braking, which recharges the battery while slowing the car — the software can let the battery overcharge. When that happens, warning lights and a buzzer go off, and the electric drive system can shut down mid-drive. This isn't a home energy story, but it matters if you own or are considering one of these vehicles, especially if you charge an EV at home or are weighing one against other electric SUVs. The affected vehicles were built between February 6, 2026, and July 10, 2026, and only the 2026 model year is involved — the 2027 C-HR is not part of the recall. Not all vehicles built in that window were sold in the US. Toyota says the fix is a free software update done at a dealership, not something sent automatically to the car. Owners will get notification letters starting October 18, 2026. In the meantime, anyone with an affected vehicle can call Toyota customer service at 1-800-331-4331, referencing recall number 26TA17, or contact the National Highway Traffic Safety Administration at 1-888-327-4236 or NHTSA.gov.
Seeing yield loss before it happens: Inline photoluminescence inspection from ingot to tandem
This is a manufacturing story, not something that changes what a homeowner does with their own roof, but it explains how solar panels get made and checked before they reach the market. A company called TTVISION Technologies makes inspection systems that use a technique called photoluminescence imaging: shining light on silicon and reading the faint glow it gives off. Bright, even glow means healthy material; dark spots mean hidden flaws like micro-cracks or contamination that would otherwise only show up as lost power once a cell is finished and installed. The company runs this check at seven stages of production, from the raw silicon ingot through wafer cutting, chemical processing, and the coating steps that go into TOPCon solar cells, a common high-efficiency panel design. Catching problems early means fewer defective cells make it into finished panels, and expensive materials like silver paste aren't wasted on wafers that won't perform well. The same inspection method is also being extended to newer "tandem" panels that pair silicon with a material called perovskite, which promises higher efficiency but is more sensitive to defects during manufacturing. For a homeowner, this is background on how the solar industry is working to make panels more reliable and consistent, potentially supporting higher efficiency and fewer early failures in panels sold in coming years. It does not point to any new rebate, product on the market today, or action to take on your own home.
How Better Room Planning Make Home Renovations More Sustainable ?
Before you tear out a wall or order new flooring, it helps to plan the layout on screen first. The idea is simple: test different room arrangements digitally before spending money on materials or construction, so you avoid costly changes partway through a renovation, like moving a wall or swapping furniture after the work has already begun. Free online tools let you enter a room's dimensions and place doors, windows, and furniture in a virtual version of the space. This can show whether your existing room can actually handle everything you want it to do — seating, storage, a workspace, clear walking paths — without adding square footage through an expensive addition. Some tools, including a free planner from Roomtodo, also let you view the layout in 3D, which makes it easier to judge scale and proportion than a flat floor plan alone. This kind of planning is especially useful for furniture and finishes. Oversized furniture can make a room feel cramped and lead you to think you need more space than you do; testing pieces in a virtual layout first can help you find better combinations of size and storage. The same goes for flooring, wall colors, and other finishes — digital previews won't replace holding a physical sample in your hand, but they can narrow down choices before you place an order, reducing the waste and expense of redoing work you're not happy with.
Tesla Autopilot was on in I-35 crash that killed its driver
A 2024 Tesla Model Y crashed on Interstate 35 in rural Missouri in April 2025, killing its 64-year-old driver when the car left the road and hit a guardrail. Police described it as a routine single-vehicle wreck with no clear cause. But Tesla's own report to federal safety regulators shows the car's driver-assist system, either Autopilot or the more advanced "Full Self-Driving" software, was active when the crash happened. Automakers are required to report crashes to the National Highway Traffic Safety Administration when these systems are engaged near the moment of impact, which is why the report exists at all. Tesla's filing confirms basic facts: the car was going 73 mph in a 70 mph zone and struck a fixed object. But Tesla blacked out the details that would explain what actually happened, including which software version was running and any account of the crash itself, citing business confidentiality. This pattern, a car drifting out of its lane or off the road while a driver-assist system is on, shows up repeatedly in Tesla's crash filings nationwide. For homeowners who own or are considering a Tesla, this doesn't change any rebate or upgrade program, but it's a reminder that Autopilot and Full Self-Driving are driver-assist features, not self-driving systems. The driver remains responsible at all times. Tesla is currently under a separate federal investigation into how it reports these crashes.
The Filter You Install Isn’t the Filter You Replace
Researchers at Purdue University have been tracking how HVAC filters perform after installation, not just when new, and found their efficiency shifts a lot over time. MERV ratings (a standard scale for how well a filter traps particles) are measured on fresh filters, but the study ran filters for over two years in real outdoor air and found some got better with age while others got worse. A basic MERV 8 filter actually improved to a MERV 14-level performance after a year, as trapped dust helped it catch more particles. A MERV 13 "electret" filter, which relies partly on an electric charge to grab particles, lost that charge over time and dropped to roughly MERV 10 performance after about six months. A MERV 14 filter held steady for nearly two years until physical damage caused it to fail. The research also found that standard MERV ratings don't account for ultrafine particles, the very smallest pollutants, which made up most of the outdoor particles entering the test system. A separate Purdue study found that swapping a MERV 14 filter for a HEPA filter cut these ultrafine particles indoors by 94%. There's a tradeoff to consider too: as filters load up with debris, they get harder for the fan to push air through, which can raise energy use or reduce airflow in the house. And bringing in more outdoor air, often assumed to improve air quality, can backfire during events like wildfires, since it let in more ozone in the tests even as it lowered indoor CO2.
Freedom Forever bankruptcy converted to Chapter 7 liquidation, key dates set
Freedom Forever, once the second-largest home solar installer in the country, has moved from Chapter 11 bankruptcy into Chapter 7 liquidation. The company filed for Chapter 11 in April 2026 and spent months trying to sell itself or find an outside investor to keep it running, similar to what happened with SunPower last year. That effort failed, and on August 7, 2026, the case converted to liquidation, with a court-appointed trustee now winding down the company's remaining assets. If you had a deposit, warranty claim, or other unresolved business with Freedom Forever, the court has set October 16, 2026 as the deadline to file a formal claim in the case. A creditors' meeting is scheduled for September 22, 2026. Separately, former employees have filed lawsuits alleging the company laid off roughly 1,600 workers without the legal notice required when a mass layoff happens. For homeowners with an unfinished solar installation financed through Freedom Forever, there is some practical news: the court has cleared the way for former financing partners — including Credit Human, EnFin, EverBright, GoodLeap, Participate, Project Solar and Sunrun — to step in and finish stranded projects. These lenders can now hire new contractors, complete the physical installation, and get systems approved for operation without going back to court each time. GoodLeap specifically was given permission to take possession of project equipment to finish jobs, and EnFin is authorized to have its consigned hardware returned. If your system was left incomplete, the financing company tied to your loan may be the one now coordinating what happens next.
Humidity Control: The Growing Role of Low-Dewpoint Cooling
This is a look at a shift in how HVAC systems handle humidity, mostly relevant to commercial buildings like labs, hospitals, and data centers rather than typical houses. The issue: a single cooling coil often has to both cool the air and pull moisture out of it at the same time, which can leave a room feeling damp even when the thermostat reads a comfortable temperature. Newer, tighter buildings make this worse, since better insulation cuts the need for cooling but does nothing to reduce moisture from ventilation air or people inside. The fix gaining traction is splitting the two jobs. A dedicated outdoor air system, or DOAS, brings in very dry air that handles all the moisture removal for a space, while separate equipment (like vents in individual rooms) only has to cool the air, not dry it. This lets that local equipment run smaller, simpler, and with less risk of the wet-coil problems that cause mold and leaks. Getting the air that dry can be done with bigger cooling systems, colder chilled water, or dehumidifiers that use desiccants (materials that pull moisture out directly) instead of cold surfaces. For homeowners, this is mostly industry and commercial building news. It does not describe a residential product, rebate, or upgrade. It is useful mainly as background: humidity control, not just temperature, is getting more attention in how buildings are designed, which may eventually influence the equipment available for homes.
New England natural gas prices have been trading near record discounts to Henry Hub
Natural gas has gotten notably cheap in New England this year. From April through July, prices at Algonquin Citygate (a major regional pricing point) averaged 43 cents per million British thermal units below Henry Hub, the U.S. benchmark price. That's the second-largest discount recorded for this stretch of the year going back to 1999. The main reasons: cheap gas flowing in from Appalachia and Canada, plus lower regional demand. Two supply trends are driving the discount. Appalachian gas, which now makes up 31% of U.S. production, is arriving in New England through pipeline connections at a steep discount to Henry Hub. At the same time, natural gas imports from Canada hit a record high, averaging 0.4 billion cubic feet per day from April through July, more than two and a half times last year's volume for the same months. Demand also dropped. Total gas consumption in New England fell 5% compared with the same period last year, partly because power plants burned 6% less gas for electricity generation. Wind power output rose 59% and solar rose 29% over the same stretch, displacing some gas-fired generation. For homeowners, cheaper wholesale gas and more regional supply don't guarantee lower retail heating bills, since utility rates depend on many other factors, but the trend points to looser, more competitive gas markets in the region for now.
How the right language can convince skeptics to support corporate climate action
A new survey of 2,000 U.S. voters found more agreement on climate issues than the usual political divide suggests. About three-quarters of all respondents said companies have a responsibility to limit their impact on climate and the environment, and more than two-thirds of Republicans agreed too. More than 60 percent said they'd be more likely to buy from companies that use more clean energy or cut carbon pollution, and most voters, including a majority of Republicans, called it "wrong" or "opportunistic" for companies to backtrack on climate commitments under government pressure. The survey, from the Center for Climate and Energy Solutions and communications firm maslansky + partners, also looked at which words work. Framing climate action as "advancing responsible, long-term energy solutions" won far more support than jargon like "accelerating the net-zero transition." Most voters, including climate-skeptical Republicans, agreed that reducing climate impact makes sense as smart, long-term business planning rather than a political statement. Fewer than half saw a company's clean-energy commitment as a political stand at all. There's a catch: voters increasingly see these same actions as political over time. The share of Democrats who called a company's move away from fossil fuels "political" rose from 40 percent in 2024 to 55 percent in 2025. This news doesn't change anything about your own home or upgrades directly, but it's a sign that clean-energy products and services may keep expanding as companies find broader public support for offering them.
Virginia kept its climate law. Dominion sees a loophole.
Dominion Energy, Virginia's largest utility, wants to build a huge natural gas plant in Cumberland County to help power growing data center demand. At 3 gigawatts, it would be nearly the biggest gas plant in the country. This tests Virginia's 2020 climate law, which is supposed to block new fossil fuel plants and phase out existing ones by 2045. Regulators can waive those rules if they decide the plant is needed for grid reliability, and Dominion used that same waiver last year to build a smaller gas plant nearby. The Cumberland plant is still years from approval. Dominion needs sign-off from county officials, an air pollution permit, and approval from state utility regulators, a process the company says could stretch into 2028, with the plant not running until 2033 at the earliest. Critics, including the Southern Environmental Law Center and local group Protect Cumberland, argue Dominion decided on gas before seriously comparing it to cleaner options like batteries and solar, and that an independent study found the state could meet demand without new gas plants by leaning more on nuclear, wind, solar, and battery storage. For homeowners, this doesn't create an immediate rebate or program change, but it matters for your electric bill. If regulators approve the plant, Dominion customers could end up paying for a multibillion-dollar facility that may need to shut down or convert to costly hydrogen fuel by 2045 to comply with the state's clean energy law, or that could keep running past that deadline under the same reliability exception Dominion is using now.
Sungrow turns to Samsung SDI battery cells to sustain its energy storage business
Sungrow, a Chinese maker of solar inverters and battery storage systems, plans to buy battery cells from South Korea's Samsung SDI, mainly to keep supplying home and grid battery systems to the U.S. market. Neither company has confirmed contract size or timing, but the deal appears tied to a larger agreement reported in South Korea worth trillions of won over three years, with several gigawatt-hours of batteries supplied annually. The move matters because U.S. rules are tightening around battery components linked to China, and companies that sell storage equipment here are looking for ways around that. Samsung SDI has been converting part of a battery plant in Indiana, run jointly with Stellantis, from electric-vehicle batteries to the lithium iron phosphate (LFP) type used in home and grid storage, with production expected to start in late 2026. It's not yet confirmed whether the cells for Sungrow would come from that U.S. plant specifically. For homeowners, this is mostly a supply-chain story rather than an immediate change to available products or prices. Sungrow has said it has no plans to build its own manufacturing in the U.S., so it's leaning on partners like Samsung SDI to keep batteries flowing here as trade rules shift. If you're considering a battery storage system, the practical takeaway is that where the cells and finished systems come from could keep changing over the next year or two, which may affect pricing, availability, or eligibility for certain incentives tied to where equipment is made.
Questionable data center forecasts are driving up Ohio power bills
Ohio power bills are rising in part because of data centers that may never actually get built. American Electric Power's Ohio utility expects electricity demand in the state to nearly triple over the next decade, mostly because of planned data centers. But researchers and manufacturing groups question whether these forecasts are realistic, since computing tends to get more efficient over time, developers often pitch the same project in multiple states, and demand for AI services is uncertain. These inflated forecasts matter because they get used to justify big spending that ends up on customer bills. In the regional grid serving Ohio and a dozen other states, capacity charges — payments that keep power plants ready for peak demand — have jumped more than tenfold since last year, largely because grid operators expect a surge in demand that may not materialize. Utilities also use these forecasts to justify building new power lines now, and in Ohio, no independent body reviews whether those "supplemental" transmission projects, which can cost billions, are actually needed. A state consumer advocate has been pushing federal regulators for three years to require more scrutiny of these costs, without much progress so far. For homeowners, the upshot is straightforward: if the data center boom falls short of projections, Ohioans could still be paying for grid upgrades and capacity that turned out to be unnecessary. Critics argue that new investment should come from the businesses driving the demand, not get passed automatically onto existing customers' bills.
SolarEdge introduces UL 3141-certified commercial power control system to streamline U.S. interconnection
This is mostly commercial news, but it points to a trend worth knowing about if you're weighing solar for your own house down the road. SolarEdge, a maker of solar equipment, has released a certified system aimed at businesses that want to add solar but are running into utility limits on how much power they can send back to the grid. As more buildings add electric equipment, EV charging, and other demand, utilities have been tightening rules on solar exports, sometimes requiring expensive electrical upgrades before a project can connect to the grid. The new system works by watching how much power a solar setup sends to the grid and automatically dialing back production to stay under the utility's cap, instead of needing custom hardware or engineering work to do the same job. It also lets businesses add more solar to an existing system later without disrupting what's already installed. In California, it's designed to work with the state's rules for limiting solar export and can help some sites keep older, more favorable solar billing arrangements (NEM 2.0) while expanding their systems, though that still depends on approval from the local utility. For homeowners, this doesn't apply directly, since it's built for commercial and industrial solar projects. But it's a sign that grid export limits are becoming a bigger factor in solar planning generally, and similar constraints can show up for home solar systems too, depending on your utility's rules.
Suniva raises $835 million to drive 4.5 GW in new domestic cell capacity
Suniva, a solar cell maker, has raised $835 million to build a new factory in Laurens County, South Carolina. The plant will add 4.5 gigawatts of production capacity and is set to open in late 2027, ramping up to full output in 2028. Combined with its existing plant in Norcross, Georgia, Suniva's total capacity will reach 5.5 gigawatts. The $600 million project is expected to create 564 manufacturing jobs. This is industry news rather than something that changes what a homeowner does right now, but it points to where solar panel costs may be headed. The U.S. government recently imposed new trade rules on imported solar cells, including a minimum import price of 22 cents per watt plus a 15% tariff. Those measures have already pushed the price of finished solar modules higher, back up to levels last seen in 2023. The tariffs make it more attractive for companies to manufacture solar cells inside the U.S., which is part of why Suniva is expanding now. For homeowners weighing a solar installation, the takeaway is that panel prices have risen recently due to these trade policies, and domestic manufacturing capacity like Suniva's new plant is one response to that shift. It will take a couple of years for this new supply to come online, so it will not have an immediate effect on quotes you might get today, but it could shape module availability and pricing further out.
U.S. clean power additions jump 45% in Q2 2026, reaching 388 GW cumulative capacity
The U.S. added a record amount of clean power to the grid in the second quarter of 2026, according to a new industry report. Developers brought 164 solar, wind, and battery storage projects online, adding 17.1 gigawatts of capacity — 45% more than the same quarter last year. Total clean power capacity nationwide is now nearly 388 gigawatts, enough, the industry group estimates, to supply more than 83 million households. Solar led the way with 7.4 gigawatts added, followed by land-based wind and battery storage. A single wind project in New Mexico, Pattern Energy's SunZia Wind farm, was the largest built in U.S. history and pushed New Mexico past Texas as the top state for new clean power additions. Battery storage capacity nationwide passed 50 gigawatts for the first time. More projects are also in the pipeline: the industry's development backlog grew to a record 205 gigawatts, and companies signed a record number of power purchase agreements (long-term contracts to buy electricity from a project) in the first half of the year. Not everything moved smoothly. Federal permitting delays slowed down wind projects in particular, pushing back more than 11.6 gigawatts of expected capacity during the quarter. For homeowners, this growth in solar, wind, and storage generally supports a bigger, more diverse supply of electricity on the grid, which can affect power reliability and prices over time, though the report does not spell out what it means for individual utility bills.
