Don’t gut the utility model just as we need it most
A recent opinion piece argues against a growing push in some states to cut utility companies' profit margins as a way to fight rising electric bills. The author, a former utility trade group executive, says the country is entering a period of fast-growing electricity demand, driven by data centers, factories, and more electric cars and appliances. Meeting that demand means building more power lines, hardening the grid against storms and wildfires, and connecting new power sources. All of that takes large amounts of borrowed and invested money. The argument is that if regulators cut the returns utilities are allowed to earn, it won't make bills cheaper. Instead, utilities would face higher borrowing costs, since investors demand more for riskier investments, and those costs would eventually land on customer bills anyway, just spread out and larger over time. The piece points to Indiana as one state where regulators are currently reviewing utility profit margins as part of a broader affordability push, a debate playing out in various forms across the country. For a homeowner, this is mostly background on a policy fight playing out among state regulators, utilities, and lawmakers, not something requiring immediate action. But it's worth knowing that "affordability" debates in your state might involve utility profit rules, not just direct rebate or rate programs. If you want to understand why your local utility is requesting a rate increase, or why regulators are reviewing its returns, this kind of dispute over financing the grid is often the reason.
Commercial crude oil inventories increased by 2.0 million barrels
This is a routine government report on the nation's oil and fuel supplies, not something that changes what you'd do with your own house. For the week ending July 17, 2026, U.S. crude oil stocks rose 2.0 million barrels to 411.7 million barrels, still 6% below the five-year average. Gasoline supplies grew slightly and remain 7% below average, while distillate fuel (used for diesel and home heating oil) rose 1.4 million barrels but stayed 10% below average. Propane supplies, often used for home heating and cooking in areas without natural gas lines, jumped 6.3 million barrels and now sit 34% above the five-year average. Refineries ran hard, at 96.1% of capacity, and crude oil imports ticked up. Demand for gasoline and diesel both rose slightly over the past month compared with a year ago, and jet fuel demand climbed 9%. Demand for things like propane and heating oil, by contrast, was down. None of this points to an immediate change in home energy costs, but the propane surplus is worth noting if your house relies on propane for heat or hot water: bigger stockpiles can mean more price stability heading into the cooler months. For homeowners weighing whether to invest in efficiency upgrades or fuel-switching, like moving from propane or oil heat to an electric heat pump, this kind of report is more background context than a signal to act on right away.
Nearly 4,000 Tennesseans Speak Out Against TVA’s Fossil Fuel-Powered Energy Plan
Nearly 4,000 people in Tennessee submitted comments criticizing the Tennessee Valley Authority's latest long-term energy plan, saying it leans too heavily on gas power and keeps aging coal plants running longer than it should. The Sierra Club gathered the comments, along with nearly 300 postcards from across the region, and filed its own technical critique of TVA's 2026 preliminary Integrated Resource Plan, the roadmap the federal utility uses to decide how it will supply power to its 10 million customers over the coming decades. The complaint: TVA's plan for new gas plants has grown, while its plans for wind and solar have shrunk compared to last year's version. Critics argue this locks customers into gas, whose price can swing unpredictably, at a time when other utilities across the South are building out more solar because it's often cheaper. Sierra Club also says TVA was slow to open a real public comment period and gave people only a short window to weigh in once it did. For homeowners in the Tennessee Valley, TVA's IRP matters because it shapes what your electricity mix looks like, and potentially what you pay, for years to come. If gas prices rise and coal plants stay in operation longer, that cost could show up on future bills. The plan is still in a preliminary stage, so nothing about your power supply changes immediately, but this comment period is part of how TVA finalizes its long-term direction.
Wisconsin gas plant proposals test state review process
Wisconsin regulators are reviewing proposals for two new natural gas power plants, and the debate touches on something that could eventually affect electric bills for homeowners in the state. Chicago-based Invenergy wants to build the Red Oak Ridge and Foundry Ridge Energy Centers, together costing $2.26 billion, mainly to supply power for large data centers, including a Microsoft campus and a project tied to OpenAI and Oracle. If approved, We Energies plans to buy both plants outright. The concern raised by environmental advocates, including the Union of Concerned Scientists, is that Wisconsin reviews plant construction and utility ownership in separate steps, rather than through a single long-term planning process used in some other states. Critics say this means regulators approve construction before fully weighing costs, alternatives, or whether the demand from data centers will actually materialize. A university study estimated the plants' air pollution could cause over $1 billion in health-related damages over 30 years. Invenergy and We Energies say the current process is thorough and that data centers will pay their own costs under a special rate structure meant to protect residential customers from cost shifts. No final vote date has been set, and construction has not been approved. For homeowners outside Wisconsin, the bigger picture is a preview of a national fight: as AI and data centers drive up electricity demand, states are debating how closely regulators should scrutinize new power plants before customers end up covering the bill.
Avantus completes Aratina 1, secures phase 2 financing, targets 952 MWh of solar-charged storage
A large solar and battery storage project in Kern County, California, has started operating. Developer Avantus says the first phase of its Aratina Solar Center, with 200 megawatts of solar power and 500 megawatt-hours of battery storage, is now sending electricity to the grid. Batteries store solar power generated during the day so it can be used later, including in the evening when demand is high. Avantus says the project will produce enough clean power for about 105,000 California homes each year, sold under long-term contracts to two community choice aggregators, which are local agencies that buy power on behalf of residents: Central Coast Community Energy and Silicon Valley Clean Energy. Avantus has also lined up $525 million to build a second phase, adding 150 megawatts of solar and 452 megawatt-hours of storage. A related project, Aratina 2, is under construction and expected to open by the end of 2026, with power going to Southern California Edison under a 15-year contract. Another Avantus project, Rexford 2 in Tulare County, is also in the pipeline. This is utility-scale development, not something tied to individual homes, but it points to a broader buildout of solar and storage across California. Avantus says it now has 13 gigawatts of solar and 44 gigawatt-hours of storage in development across California, Nevada and Arizona. Industry group SEIA projects the state will add nearly 23 gigawatts of solar capacity over the next five years, largely through projects like this one, as California works toward its grid reliability goals.
Tesla sets net-zero target for first time
Tesla has set its first company-wide deadline for reaching net zero (cutting its overall emissions to effectively nothing), pledging to get there by 2040. The company had talked about net zero before but never attached a date until this month's annual Impact Report. Tesla also repeated two earlier promises: to run its own operations on 100 percent renewable electricity before hitting net zero, and to match the electricity used by its Supercharger charging network with renewable power. For homeowners, this is mostly background on how Tesla positions itself as a climate company, rather than something that changes solar panels, batteries, or vehicles you might buy. Tesla still leans on the argument that its products avoid emissions elsewhere, estimating each vehicle avoids about 32 metric tons of carbon dioxide equivalent over its lifetime, and that its cars, solar, and batteries together avoided close to 37 million metric tons in 2025. Meanwhile, the company's own emissions from operations and purchased electricity have grown sharply since 2023, and it has not laid out a near-term plan or detailed targets for lower-carbon materials like batteries, steel, or aluminum, something other automakers have started doing. None of this affects rebates, incentives, or purchase decisions directly. It is a signal of how Tesla plans to talk about its climate impact going forward, and a reminder that a company's environmental record involves both the products it sells and the emissions from making them.
Tesla (TSLA) releases Q2 2026 financial results: record revenue, big profit miss
Tesla's second-quarter 2026 results are not really about home energy upgrades, but here's the gist for anyone curious. Tesla reported record revenue of $28.24 billion, up 26% from a year earlier, driven by record car deliveries and a 50% jump in services revenue. But profit fell short of expectations: per-share earnings came in well below what analysts predicted, and operating income dropped 57% as the company spent heavily on AI, its Optimus robot, and robotaxi development. A big piece of the profit squeeze involves regulatory credits, which are payments automakers make to each other tied to fuel-economy and emissions rules. Tesla earned far less from these credits this quarter, down two-thirds from a year ago, mainly because the $7,500 federal EV tax credit expired at the end of September 2025 and a change in federal law removed the penalties automakers previously paid for missing fuel-economy targets. That market for buying and selling credits has essentially dried up, and Tesla says it isn't coming back. None of this changes what rebates or incentives exist for home upgrades like heat pumps or insulation. It's a snapshot of Tesla's business health and a reminder that federal EV incentives have already changed. If you're weighing an EV purchase or already own one, it may be worth checking what federal and state incentives, if any, still apply in your area, since the landscape has shifted this year.
12-MWh BESS project in Nebraska nears finish line
A large battery storage project in Lincoln, Nebraska is about to go live. The system, sized at 3 megawatts and 12 megawatt-hours, uses zinc-based batteries from Eos Energy along with software from Wattmore to monitor performance and schedule when the battery charges and discharges. It's being built for Lincoln Electric System, the local utility, and is finishing up commissioning in the next few weeks. This isn't a home battery — it's a grid-scale project meant to help the utility manage electricity supply across the whole system. Lincoln Electric System says it fits into a broader plan to make the local grid more reliable and to help manage energy costs over time. Projects like this can eventually affect what homeowners see on their utility bills or how well the grid holds up during high-demand periods, since utility-scale storage helps smooth out supply and demand rather than relying only on power plants running at full tilt during peak hours. There's nothing here for homeowners to sign up for or apply to — no rebate, no incentive, no program tied to individual houses. It's simply an infrastructure project moving toward completion. If you're in Lincoln Electric System's service area, this is background context on how your local utility is investing in grid reliability, not something that changes your own home energy plans directly.
rPlus Energies advances 525 MW of Idaho solar amid accelerating state market growth
Idaho is adding a large amount of solar power to its grid, though the news is more about the state's energy supply than anything homeowners need to act on. Developer rPlus Energies has finished building the 125-megawatt Pleasant Valley Solar 2 project and started construction on the 400-megawatt Blacks Creek Energy Center in Ada County. Together the two projects represent over $750 million in investment and push rPlus's total Idaho solar and battery storage projects past 1 gigawatt. Both will sell power to Idaho Power under long-term contracts. The projects are part of a broader trend: Idaho now has 1,301 megawatts of installed solar capacity, ranking 34th in the country, with more than $2 billion invested statewide so far. Solar currently supplies about 9% of Idaho's electricity, and industry forecasts expect another 2,740 megawatts of new solar over the next five years. Idaho Power is also expanding battery storage to help balance the grid, with a 300-megawatt storage project planned for late 2026 and a longer-term goal of 1,685 megawatts by 2040. For homeowners, this mainly means more solar and storage capacity feeding into the regional grid over time, which utilities say will help meet rising electricity demand. The projects are also expected to bring construction jobs and tax revenue to local communities, plus $375,000 in scholarship funding for students at Boise State University and the College of Western Idaho. There is no new rebate or program here for homeowners to apply for.
Extreme heat and indoor air quality: What schools need to know
A recent webinar looked at how schools in the West and Southwest are dealing with extreme heat and indoor air quality (IAQ), the general health and comfort of the air inside a building. Experts explained that heat inside a classroom isn't just about temperature. Humidity, sunlight, and building design all play a part, and rising temperatures can also cause building materials to release more emissions into the air, straining older heating and cooling systems. The discussion pointed to strategies that treat cooling, ventilation, and air quality as connected problems rather than separate ones. These include upgrading HVAC (heating, ventilation, and air conditioning) systems, adding shade structures, installing reflective roofing, and creating dedicated cool-down spaces. One school district, Oakland Unified, shared how it uses temperature and carbon dioxide sensors in classrooms to figure out which schools and rooms are hit hardest by heat, then directs repairs and upgrades to those places first. While this news is aimed at school facilities, the same ideas apply to houses. Aging HVAC systems, poor shading, and heat-absorbing roofing can make homes harder to keep cool and can affect indoor air quality, especially during heat waves. If your home struggles with heat or stuffy air in summer, it may be worth thinking about similar fixes: better shade, more reflective roofing, or an HVAC system upgrade, and whether any local or state rebate programs help cover those costs.
Donated solar system to aid Denver-based refugee support organization
A group of solar companies has donated a 60-kilowatt solar system to Project Worthmore, a Denver nonprofit that supports refugees in the area. The companies involved include SolarEdge Technologies, Apollo Energy, Pivot Energy, IronRidge, Greentech Renewables and Rexel. The system now powers the nonprofit's newly renovated 20,000-square-foot campus in Denver. The donated system is expected to save Project Worthmore more than $350,000 over 20 years by eliminating most of its electricity costs. The organization plans to put those savings toward educational classes, community programs and shared spaces that serve refugee families and other local groups in the Denver area. This story is about a corporate donation to a specific nonprofit, not a program homeowners can apply for. It does not involve any rebate, tax credit or incentive available to the general public. If you are considering solar for your own home, this is worth knowing simply as an example of how much a system that size can cut electricity costs over time, but the donation itself, and the companies who provided it, are specific to this one Denver organization.
Amazon cloud customers can now see their water withdrawal data
This is not about home energy upgrades, but it touches on a topic connected to them: the water and electricity used by big data centers, the kind that power cloud computing and, increasingly, artificial intelligence. Amazon Web Services now lets business customers see how much water their cloud accounts use, through a dashboard called the AWS Sustainability Console. The "withdrawal" numbers cover water used to cool data centers and for other purposes, like fire protection tanks. Amazon built its own method for calculating this, similar to how it already estimates the greenhouse gas emissions tied to customer accounts, and it offers historical data back to January 2022. The bigger picture: data centers run by Amazon, Google, and Microsoft use large amounts of both water and electricity, and the two are linked, since some cooling systems that save water use more power, and vice versa. All three companies have promised to cut freshwater use in their data centers. Microsoft has built a closed-loop cooling system for AI facilities and publishes water-use data for certain AI queries. Google says it replenished more freshwater than it used in 2025 through projects in water-stressed areas, but does not share water data for individual customers the way Amazon now does. None of this changes anything about home energy programs or rebates. It is a sign that the companies behind cloud and AI services are facing more pressure over their resource use, as that use keeps growing alongside demand for artificial intelligence.
It’s Time To Adopt A New Mindset About The Planet
This piece is an opinion essay arguing for a broader shift in how society holds corporate polluters and political leaders accountable for climate change. It touches on several policy fights but doesn't offer any new programs, rebates, or upgrades for homeowners. Among the items mentioned: a Trump administration proposal would stop classifying pyrolysis units (which heat plastic waste at very high temperatures) as incinerators under the Clean Air Act, meaning they'd no longer face limits on cancer-causing pollutants and other emissions. The piece also notes a federal bill introduced by Republicans that would shield fossil fuel companies from lawsuits over their role in climate change, and it flags that a federal restoration program (the "America the Beautiful" initiative, tied to over $2 billion in funding from the Bipartisan Infrastructure Law and Inflation Reduction Act) has had its website taken down under the current administration. It also references a National Academies report supporting the science linking extreme weather to climate change. None of this changes any rebate, incentive, or upgrade program available to homeowners right now. It's a call for political and civic engagement — voting, contacting legislators, and public pressure — rather than a report on new home energy options. If you're weighing an upgrade, this doesn't affect your eligibility or costs; it's about the larger policy debate playing out around climate accountability.
ARRAY Technologies unveils solar tracker with 60° stow angling
This is equipment news for large solar farms, not home solar systems, but it's worth knowing what it means. ARRAY Technologies has released a new version of its DuraTrack solar tracker, a motorized system used at utility-scale solar sites that tilts panels to follow the sun through the day. The new model can angle panels up to 60 degrees when tucked away, or "stowed," during severe weather. The tracker includes technology that automatically detects incoming hail and wind, then moves the panels into a protective position to reduce damage. It uses a wired power and communications setup rather than batteries and wireless signals, which the company says makes it more dependable. ARRAY says the goal is to cut down on unnecessary stowing and sensor problems, while holding up better in regions prone to hail, such as Texas and the Great Plains. For homeowners, this doesn't apply directly to rooftop solar panels, which use fixed mounts rather than the moving tracker systems built for ground-mounted commercial and utility solar farms. But it does reflect a broader trend in the solar industry: more attention to protecting equipment from hail and severe weather as storms become a bigger concern for insurers and developers. If you're weighing rooftop solar for your own home, storm resilience for your specific panels and mounting hardware is worth asking about, though it works differently from the tracker systems described here.
China’s Electric Trucks, Diesel’s Peak, and What Western Planners Still Don’t See
China is rapidly shifting its trucking fleet from diesel to electric, and the change is bigger than it looks at first glance. The country's plan calls for new-energy heavy trucks to make up around 40% of sales by 2030, roughly 1.6 million vehicles on the road, aimed first at high-mileage routes like ports, mines, and steel mills. Because these trucks drive longer hours and repeat the same routes, a relatively small share of vehicles can cut a large share of diesel use. China is also building out 30,000 kilometers of dedicated freight corridors with charging and battery-swap stations to support this shift, and the International Energy Agency now expects China's oil demand to peak this decade as a result. This doesn't have a direct bearing on your house, furnace, or utility bills. But it's a sign of how fast the broader shift away from fossil fuels is moving globally, driven by China's manufacturing scale in batteries, electric vehicles, and charging infrastructure. Some of that same manufacturing scale is part of why heat pumps, batteries, and other home electrification equipment have gotten cheaper in recent years. The piece also touches on Australia, where the authors argue that regions dependent on imported diesel face rising exposure as global fuel demand patterns shift, and they suggest other countries, including Australia, will need their own coordinated infrastructure investment to keep pace. That's a policy and industry conversation, not something requiring any action on your part.
Isuzu to Use Swappable Battery Tech for Yokohama’s Garbage Collection Route
Isuzu is testing a battery-swapping system for electric garbage trucks in Yokohama, Japan, where a depleted battery pack can be pulled out and replaced with a charged one in about three minutes. The idea is to avoid the long charging stops that electric trucks normally need, since garbage collection runs on a tight single daytime shift with no time for a vehicle to sit plugged in for an hour or two. The trial with the City of Yokohama runs through March 2028 and will test whether the swap system can keep trucks running their full routes, including powering the hydraulic compactors that make these vehicles especially power-hungry. This isn't a home energy story, but it points to where battery technology is heading for vehicles that can't afford downtime. Swappable batteries let trucks use smaller, lighter packs instead of the oversized batteries needed for all-day range, which can lower cost and weight. Isuzu already tested similar swap technology on delivery trucks in Yokohama last year, and other manufacturers, including Mitsubishi Fuso, are running comparable programs with delivery fleets in Kyoto and Tokyo. None of this changes anything about home electric vehicle charging or rooftop solar setups right now. But the same battery-swap concept, if it works well, could eventually show up in other specialized vehicles like street sweepers or utility trucks. It's an early-stage commercial fleet experiment worth watching rather than something that affects home upgrades today.
Most Utahns want to protect their national monuments. Trump had other plans.
This is a public lands story, not an energy-efficiency or rebate item, so it doesn't touch home upgrades directly. Here's what happened for anyone following it out of general interest. President Trump signed executive orders cutting Bears Ears National Monument in Utah from 1.35 million acres to about 121,000 acres, and Grand Staircase-Escalante from nearly 1.9 million acres to just over 181,500 acres — roughly 90 percent reductions each. Utah's Republican governor and congressional delegation stood with him, saying the cuts reflect what Utahns want, citing access to critical minerals like copper, nickel, and uranium in the region. But polling tells a different story. Utah State University surveys from 2024 and 2025 found 61 percent of Utahns supported keeping Bears Ears protected, and only 26 percent favored shrinking it. A separate 2024 poll found 71 to 74 percent of Utah voters wanted both monuments kept intact. Across eight Mountain West states, a Colorado College poll found 91 percent of voters, including 87 percent of Republicans, wanted existing monuments preserved. Trump's order also disbanded an intertribal commission that had advised on managing Bears Ears, even though a 2024 poll found most Utahns wanted tribes to keep a strong role in managing those lands. Hundreds protested the cuts outside the Utah governor's mansion this week, organized by the Southern Utah Wilderness Alliance.
Salesforce expands disclosures about AI environmental impact
This is corporate software news, not a home energy story, so it has little bearing on your own house. Salesforce, the business software company, has started adding energy use and carbon emissions data to the "model cards" it publishes for some of its artificial intelligence tools. Model cards are fact sheets that explain how an AI model was built, how it performs, and where it might be used. Salesforce is now including electricity consumption and emissions figures alongside that information, something few other companies in the industry do. The change applies first to models Salesforce trained itself, including tools used to match names and accounts in its software. The figures come from the AI Energy Score, a measurement system built by Hugging Face, an open-source software company, in a project started by former Salesforce sustainability executive Boris Gamazaychikov and computer scientist Sasha Luccioni. That system looks at the computing hardware, data center location, and run times behind common AI tasks like image generation or speech recognition. Salesforce says it plans to expand this reporting to more of its AI models over time, as it gets easier to measure the energy used when AI is actually put to work, not just when it is trained. For homeowners, this is a look at how AI companies are starting to disclose environmental costs of their products, not a change to any home energy program or rebate.
CATL Is Building The Electric-Truck Platform Europe May Have To Join
A new company called Swaptopus, formed by CATL (the world's largest maker of electric-vehicle batteries) and Octopus Energy, plans to build automated battery-swap stations for heavy trucks across Europe. Instead of plugging in and waiting to charge, a truck would pull into a hub and swap its depleted battery for a charged one in minutes. The first UK hubs are set to open in 2027, with more than 30 planned across Europe by 2035. The companies claim the network could eventually serve over 300,000 trucks and draw more than £30 billion in private investment, though that's described as a long-term ambition rather than a near-term guarantee. This is a freight-industry story, not a household one. It doesn't involve home chargers, rooftop solar, or any equipment homeowners would install. The batteries in question are large truck packs, far bigger than anything used in a home battery or an electric car. The bigger issue raised is whether Europe's truck makers end up designing their vehicles around a battery format and software system controlled by a Chinese company, similar to how phone makers depend on chip and software platforms they don't own. For homeowners, the practical takeaway is limited: this concerns highway freight infrastructure, not home energy upgrades or rebates. It's worth knowing about mainly because it shows how battery swapping, an idea sometimes floated for consumer cars, is instead taking hold in commercial trucking first.
EVs And The North American Auto Industry — A Canadian Perspective
Canada's government is now letting up to 49,000 Chinese-made cars into the country each year at the standard tariff rate, instead of the extra 100 percent tariff added under the previous government. This is largely a policy story about trade and manufacturing, not something that changes what's available at a Canadian dealership overnight, but it touches on why electric vehicles cost what they do. The core issue experts point to is price. Electric vehicles cost less to run since electricity is cheaper than gas, but the upfront sticker price has kept many buyers away. Cheaper Chinese EVs entering the market could pressure other automakers to lower prices, similar to what happened in Europe. Separately, Canada already has an Electric Vehicle Affordability Program offering federal rebates on EVs priced under $50,000 Canadian, as long as the vehicle is assembled in Canada or in a country with a free trade agreement with Canada — worth checking if you're shopping for an EV and want to know what qualifies. Experts quoted in the piece stress that lower prices alone won't drive adoption. Charging availability, financing, insurance, and repair infrastructure all need to develop alongside cheaper vehicles. For a homeowner deciding whether to go electric, the takeaway is that vehicle prices may become more competitive over time, but the surrounding support systems — like charging access — are still catching up, so it's worth watching how quickly that infrastructure improves in your area before assuming an EV purchase will be smooth from day one.
Electric, autonomous, and there’s 800 of them: inside this week’s BIGGEST deal
A Chinese heavy equipment maker, Tonly, has agreed to supply 800 self-driving electric mining trucks to a mining company in Xinjiang, in northwest China. The trucks run on swappable battery packs and are part of a broader push by mining operators to replace diesel haul trucks with electric, autonomous ones. The truck involved, Tonly's DTE145, is a 90-ton hauler with a 770 kWh battery (with a larger 1,200 kWh option available) that can either plug in to charge or swap out a depleted battery pack for a fresh one in about seven minutes. That swap time is faster than refueling a comparable diesel truck, which is one reason mining companies are moving toward electric fleets: lower fuel costs, less maintenance, and now, quicker turnaround between shifts. This news is about industrial mining equipment in China, not home energy upgrades, so it doesn't affect anything you'd do to your own house. But it's a sign of how fast large-scale electric and battery-swap technology is scaling up outside the passenger-car world, in machines that haul dirt and rock around the clock. The battery and fast-swap technology being proven here, made by CATL, a major battery supplier, is part of the same wave of advances that eventually filters down into batteries and charging systems used in homes and electric vehicles.
Coronavirus disease 2019
This isn't news about home energy upgrades or rebates, so there isn't a homeowner angle to summarize here. The text is a general medical overview of COVID-19, covering how the disease spreads, its symptoms, and prevention measures. In short, it describes COVID-19 as a contagious disease that spreads through the air, especially in close contact or poorly ventilated indoor spaces. Common symptoms include fever, cough, fatigue, and loss of smell or taste, though many infected people never notice symptoms at all. Most people who do get sick have mild to moderate cases, while a smaller share develop severe or critical illness, with older adults facing higher risk. Some people experience lingering effects, sometimes called long COVID, that can last months or years. The piece also notes that vaccines have been developed and distributed widely, and that measures like ventilation, masks, and hand washing help reduce spread. Testing relies on lab methods that detect the virus's genetic material from a nasal swab. Treatment mostly focuses on managing symptoms rather than curing the infection directly. None of this relates to insulation, heat pumps, weatherization, or rebate programs, so there is nothing here that affects decisions about home energy upgrades.
EU Backs Electrification to Make Europe More Secure
The European Commission has set a goal to nearly double how much of Europe's energy comes from electricity, aiming for 46% by 2040. The plan is a response to Europe's heavy reliance on imported fossil fuels, which make up more than half of its energy supply, and it puts special focus on transportation, since cars and trucks still run on fossil fuels for over 90% of their energy. A key piece of the plan involves electric vehicles. The Commission wants EVs to work as "batteries on wheels" through a technology called vehicle-to-grid (V2G), where a car's battery can feed power back into the electric grid, not just draw from it. This could help store extra solar and wind power for times when the sun isn't shining or the wind isn't blowing, and could ease strain on power grids that might otherwise need expensive upgrades. One gap noted by the group Transport & Environment: the plan doesn't require automakers to include the onboard hardware needed for V2G, meaning drivers might still have to pay extra for equipment to use the feature. The plan also calls for heat pumps and household batteries as part of the broader shift away from gas and oil, and sets a target for charging infrastructure at ports to support electric ferries by 2040. This is European Union policy, not a U.S. program, so it doesn't come with rebates or rules for American homeowners. But it signals where heat pump and home battery technology, along with EV charging standards, may be headed globally in the coming years.
This country went 100% electric vehicles overnight with a drastic approach
Laos has banned the import of new gas and diesel passenger cars, starting June 1 and running through the end of 2026. Since combustion vehicles can no longer come in, nearly every new car entering the country is now electric. The ban has exceptions, though: public transit vehicles, construction equipment, and project trucks are still allowed to run on diesel. To push the switch, Laos is exempting electric vehicles under $50,000 from excise tax, cutting EV registration fees, and requiring transport companies to make at least 10% of their fleets electric by year's end. The country is also working with 27 public and private partners to build charging stations and battery-swap sites, aiming for 30% of all vehicles to be electric by 2030. This isn't really about climate goals. Laos runs mostly on hydropower it produces itself, but it has to pay for every drop of gasoline and diesel in foreign currency it doesn't have much of. Switching cars to electricity keeps that money at home. Chinese automakers are filling most of the new demand, since they already sell affordable EVs in the region. None of this changes anything for a US homeowner's own car or utility bills, but it's a sign of where things are heading globally: countries with cheap homegrown electricity and expensive imported fuel are increasingly betting hard on electrification, sometimes by removing the gas-powered option entirely rather than waiting for buyers to choose EVs on their own.
July 2026 issue: The 15th Anniversary Top Solar Contractors List
This is a trade industry milestone, not a specific product or program update, but it's a useful signal for anyone comparing solar installers. A national ranking of solar contractors just marked its 15th year, and this year's list shows the industry has a lot of staying power: 226 of the companies on the 2026 list have more than 15 years of experience, and another 55 have over a decade, meaning more than 72% of the companies ranked have been doing solar work for at least 10 years. The ranking notes that many of these companies made it through a rough recent stretch of policy changes, tariff shifts, and supply shortages, which the industry frames as a sign of resilience. It also points to broader momentum for solar nationally, including a claim that U.S. solar generation has overtaken coal for the first time and that the country has now passed 6 million individual solar installations. For a homeowner weighing a solar installation, the practical point is simply that longevity and track record vary a lot among installers, and lists like this one exist as one way to see which companies have been in the business longest. No new rebate, incentive, or program is announced here, and nothing changes about your own eligibility or costs. If you are shopping for solar, it may still be worth checking how long a company has operated before signing a contract.
Toyota’s next-gen Corolla EV takes center stage as a ‘sense of crisis’ reshapes the company
This is car industry news and doesn't connect to home energy upgrades or rebates, so there isn't a homeowner angle to draw out here. Briefly, though: Toyota is developing a next-generation version of its Corolla, including an electric version, built on a new platform flexible enough to support gas, hybrid, plug-in hybrid, and fully electric versions of the car. Company chairman Akio Toyoda described a "considerable sense of crisis" inside Toyota as it faces growing competition from Tesla and Chinese automakers like BYD. The report, based on a Japanese television special that went behind the scenes at Toyota's development site, showed several body styles under work, including a sedan, hatchback, crossover, and sport model. Engineers interviewed acknowledged concerns that Toyota's development and manufacturing pace is falling behind Chinese rivals. The design closely follows a concept Toyota showed last October, with a low, sporty look. None of this changes anything about home energy costs, electric vehicle charging incentives, or rebates available to homeowners right now. It is simply a look at how one of the world's largest carmakers is responding to competitive pressure in the shift toward electric vehicles, with no specific launch date given for the production version of the car.
Range Rover’s next EV is unlike anything the luxury brand has built before [Images]
This is a car news item, not directly tied to home energy upgrades, but here's what happened: Range Rover has revealed the first images of a new all-electric model called the GT, a lower, sportier-looking car than the brand's usual boxy SUVs. It will ride on Jaguar Land Rover's new EMA platform and is described as the most technologically advanced Range Rover yet. The interior drops the traditional gauge cluster for a single center screen and a slim driver display, with no physical buttons. Battery details haven't been finalized, but the GT is expected to use a battery pack over 100 kWh, potentially giving close to 500 miles of range on the European testing cycle, or at least 300 miles under the EPA's US rating. That would put it ahead of Range Rover's flagship electric SUV, which uses a 118 kWh battery for 373 miles of range. The GT will launch as a pure electric vehicle first, with a hybrid version added later. Production starts in the first half of 2027 in the UK, after the flagship Range Rover Electric and Range Rover Sport EV go on sale. Pricing hasn't been confirmed, but the GT is expected to start above $100,000, with US pricing possibly closer to $90,000. For homeowners, this doesn't affect any energy-efficiency programs or rebates, but it's a sign that longer-range electric vehicles with home-charging needs are continuing to expand into more vehicle categories, including luxury grand tourers.
Anker SOLIX Summer Camp power station sale with exclusive savings from $189, HiEHA CarPlay SU8 2.0 e-bike low, EcoFlow, more
This roundup covers a batch of discounts on backup power gear and outdoor electric equipment, mostly aimed at people who already have or are considering battery power stations, e-bikes, or robot lawn mowers for their home. Anker's SOLIX Summer Camp sale offers portable power stations starting at $189, with extra bundled savings on top. These stations store electricity you can draw on during an outage or for off-grid use, so they're worth a look if you want backup power without whole-home battery installation. EcoFlow has a separate five-day flash sale for members, with six deals starting at $1 and including its 3600Wh Delta Pro power station at $1,499. Bluetti also has a July member sale on power stations, batteries, and solar panels starting at $189, though that one is wrapping up soon. On the equipment side, HiEHA's SU8 2.0 e-bike, which connects to Apple CarPlay, is down to $750, with a dual-battery version and an older first-generation model also discounted. For yard work, Segway's Navimow i105N and i110N robot lawn mowers start at $669, and Roborock has a new robot mower, the RockMow X120H, which uses lidar sensors and all-wheel drive, priced at $2,500. None of these are utility rebates or efficiency programs — they're retail sales on consumer energy and yard equipment. If you're weighing a portable power station for outages or an electric mower or bike for your property, these discounts may be worth comparing against your own needs and budget.
Tesla Model Y & Model 3 Dominate US EV Market, But Who Completes The Top 10?
New sales figures for the second quarter of 2026 show the Tesla Model Y and Model 3 still lead US electric vehicle sales by a wide margin, with 84,863 and 34,944 sold. The Hyundai Ioniq 5 came in third with 10,940, now selling at almost a third the rate of the Model 3. The Toyota BZ (formerly the BZ4X) took fourth place, and the Ford Mustang Mach-E rounded out the top five. The Chevy Equinox EV, Rivian R1S, and Honda Prologue were the only other models to sell more than 5,000 units in the quarter. Looking at year-over-year change, the picture is mixed. The Toyota BZ and its new sibling, the Toyota C-HR, saw the biggest gains, along with the Chevy Bolt, Kia EV9, and two new Subaru models, the Uncharted and Trailseeker. On the other end, the Tesla Model 3 posted the steepest drop of any model, losing nearly 14,000 sales compared with a year earlier, which helps explain why the Ioniq 5 has closed the gap. The Chevy Equinox EV also fell sharply, and the Nissan Ariya, which is being discontinued in the US, saw a big decline as expected. Overall, more models lost ground than gained. For a homeowner weighing an EV purchase, this mainly confirms that Tesla's two mainstream models remain the default choices, but competition is growing, with the Ioniq 5 and Toyota's electric lineup gaining real traction.
GAC Aion V & UT Enter Australian Market
A Chinese automaker called GAC has launched two electric cars in Australia: the Aion UT, a city hatchback, and the Aion V, a midsize SUV. Both are priced around AU$32,000, putting them in direct competition with the BYD Atto 2 and MG4 Urban, which sell at similar prices. The Aion UT stands out on range, with a 60 kWh battery (using LFP chemistry, a battery type known for durability and lower cost) rated at 430 km, compared with 345 km for the Atto 2 and 316 km for the MG4 Urban. GAC has set up 30 dealerships across Australia, signaling it plans to stick around. This news mostly matters if you're shopping for an EV and live in a market where these cars are sold, since none of this applies directly to a US home's energy upgrades. Early owners report strong build quality and quick heating and cooling, though the car's software tends to nag with frequent safety alerts, some triggered even when no one is in a seat. Reviewers found the claimed 430 km range held up in real driving. The Aion V has also earned a five-star safety rating from ANCAP, Australia's crash-test authority. For homeowners elsewhere, the main takeaway is a broader trend: more affordable EV options are entering markets as manufacturers compete on price and range rather than just speed. If you're weighing an EV purchase alongside other home energy upgrades, it's a reminder to check what's actually available and priced competitively where you live, since lineups and pricing vary widely by country.
Electrek Formula Sun Grand Prix 2026: Day 1 results and gallery
This one is a student solar car race, not a home energy story, so there's nothing here about upgrades, rebates, or your own house. Worth a quick note only because it's a fun showcase of solar technology in action. College teams from the US, Canada, the Netherlands, and Belgium raced solar-powered cars at the Formula Sun Grand Prix, held this year at Brainerd International Raceway in Minnesota. A record 39 teams signed up, and 15 passed safety inspection to race on day one of the three-day event, making it the largest and most international running of the competition so far. In the single-seat car class, a team from École de technologie supérieure in Quebec led after day one with 112 laps and the fastest single lap, averaging nearly 53 mph on the 3.1-mile track. In the multi-seat class, Georgia Tech led with 77 laps, ahead of Appalachian State's 55, though App State posted the quicker single lap. Several other schools had not yet posted a scoring lap as of day one, with two days of racing left. If you're curious about solar power generally, this kind of event mostly shows off engineering extremes rather than anything you'd install at home. It has no bearing on rebates, tax credits, or equipment choices for a house.
XPENG Collaborates with Google Maps, Bringing a Complete Refresh of In-Car Navigation and ADAS Support Built into Its Ambitious New Model L03
This is car industry news, not a home energy story. Chinese automaker XPENG launched a new electric SUV, the L03, in Munich, Germany, as part of a rollout to 65 countries and regions. Alongside the launch, XPENG announced it is building Google Maps directly into its vehicles outside China, using Google's Auto SDK (a toolkit that lets carmakers design their own navigation screens on top of Google's map data). XPENG is the first automaker from the Asia-Pacific region to do this. Practically, this means XPENG drivers won't need to mirror their phone or download a separate app to get Google Maps features like real-time traffic, place search, and trip planning. The map data will also feed the car's driver-assist systems, including route guidance for its automated driving features, and help estimate energy use on electric vehicle trips. Nothing here concerns home energy upgrades, rebates, or weatherization. It's about in-car technology and a foreign automaker's global expansion. If you're weighing an electric vehicle purchase down the road, this signals that navigation and driver-assist software in EVs continues to improve, and that automakers are increasingly partnering with familiar map services rather than building everything in-house. But there's no rebate, deadline, or program here that touches your house, your utility bill, or any home retrofit decision.
Candid Chinese EV Conversation With Kim Java & Rich Benoit
This isn't really news you can act on at home. It's a writeup about a video conversation between three EV commentators—Larry Evans, Kim Java, and Rich Benoit—recorded in Munich around the launch of a Chinese-made electric car, the XPENG L03. The piece is mostly a personal reflection on having an honest, wide-ranging talk about Chinese EVs and how they might shake up established automakers and oil interests, plus a plug to watch the video. There's nothing here about home energy upgrades, heat pumps, insulation, or rebates. It touches on electric vehicles only in the context of global auto industry politics and the rise of Chinese EV makers, not charging equipment, home electrical work, or any incentive program a homeowner might use. If you're weighing an EV purchase and wondering how it connects to your house—say, adding a home charger or checking whether your utility offers an EV charging rebate—this piece won't help. It's commentary on the broader EV market and industry dynamics, not a guide to what's changing for your home or wallet.
Exclusive: Segway teases more electric bikes, including a street-legal next-gen Xyber
This is outside the usual scope of home energy upgrades, but here's the news: Segway plans to release two new electric bikes before the end of 2026, both expected to arrive sometime in the third quarter. The company shared the news directly with a reporter, though most details are still under wraps. The bigger news is a redesign of Segway's Xyber model. The current Xyber sits somewhere between an e-bike and a lightweight electric motorcycle, but the next version is being built to be street-legal, with a selectable Class 1, 2, or 3 mode depending on what's allowed where you live. E-bike classes typically refer to speed and whether the motor assists only while pedaling or also works with a throttle. Making the Xyber switchable between these classes would let more riders use it under standard e-bike rules rather than motorcycle rules. Segway says the new version keeps the original's look and adds more everyday features, connected tech, and rider-adjustable settings, but exact specs, price, and release date are not yet available. Segway also confirmed a second, entirely new e-bike is coming, without offering any details on what it will look like or do. This follows a busy stretch for the company, which has already launched a commuter e-bike (Myon), a cargo bike (MUXI), and an electric dirt bike this year. None of this affects home energy programs or rebates, but if you're shopping for a bike, it's worth knowing Segway's lineup is about to grow again.
Tesla Autopilot and FSD crashes hit record 207 in a single month
Tesla reported 207 crashes involving its Autopilot or Full Self-Driving (FSD) systems in May 2026, the highest single-month total on record, according to the company's own reports to federal safety regulators. These are crashes where the driver-assist system was active shortly before impact and where something serious happened, like an airbag deploying, a tow-away, an injury, or a struck pedestrian or cyclist. Tesla now accounts for roughly 3,763 such crashes total, about 85 percent of all driver-assist crash reports across the industry, and 2026 is on pace to roughly double last year's count. Part of this rise is simply more Teslas on the road logging more miles with these systems turned on, so more crashes are expected even if the technology is getting safer per mile driven. But there is no way to check that, because Tesla does not publish reliable data on how many miles Autopilot and FSD actually drive. Tesla also blacks out nearly all detail in its crash reports, including what version of the software was running, so the public record cannot even tell whether Autopilot or FSD was more often involved. For homeowners, this is not a home-energy story, but it is a reminder for anyone who owns or is considering a Tesla with these driver-assist features: the systems are improving, but they remain Level 2, meaning the driver is still legally responsible at all times.
Hyundai’s new patent points to an upcoming off-road electric SUV
This one isn't about home energy upgrades, but here's what's happening. Hyundai has filed a design patent that appears to preview an off-road electric SUV, closely resembling the Boulder Concept the automaker showed earlier this year at the New York Auto Show. The patent, filed in India by Hyundai and Kia, shows the same boxy shape, oversized tires, and coach-style doors as the concept, but with a mostly closed-off front grille and slimmer LED headlights. The closed grille is one clue that this version could be a fully electric vehicle, since EVs don't need as much airflow to cool an engine. The Boulder Concept itself is meant as a preview of Hyundai's first body-on-frame vehicle for the US market, though that first model will actually be a midsize pickup truck rather than an SUV. Hyundai hasn't confirmed powertrain details yet, but the pickup is expected to ride on a platform offering fully electric, plug-in hybrid, and extended-range electric versions. The pickup is part of a larger plan to launch 36 new vehicles in North America by 2030. There's no word yet on when, or if, a production version of the off-road SUV shown in the patent will actually reach dealers. For homeowners, this is simply industry news about upcoming vehicle designs, not a program or purchase decision with immediate relevance to your house or energy bills.
Ebikes Are Perfect for Injury Recovery Exercise
This piece is a personal essay rather than a news story, so there's no program, deadline, or rebate to report. The writer, an ebike enthusiast, argues that electric bikes are a good tool for easing back into exercise after an injury. The idea is simple: on a regular bike, if a healing muscle or joint starts to hurt mid-ride, you either push through pain or stop entirely. On an ebike, you can dial up the motor's assistance for a few minutes, keep moving without straining the injured area, then ease off the assistance again as you feel ready. That flexibility, he says, makes it easier to stay active without re-injuring yourself or losing your exercise habit altogether. He also notes that once you're fully recovered, an ebike still works fine for regular exercise, fitness, and time outdoors. He contrasts this with higher-impact sports like tennis or basketball, where it's harder to scale back effort mid-game without letting teammates down. For a homeowner, there's no rebate or purchase program mentioned here, no price figures, and no state-specific rules to check. This is simply an opinion piece about ebikes as a low-strain way to stay active, especially for older adults or anyone recovering from an injury, not a report on incentives or new products.
France won’t approve Tesla ‘FSD’ yet, wants EU-wide sign-off first
This is car news, not home energy news, so there's not much here that touches your house directly. France's transport minister, Philippe Tabarot, says the country won't approve Tesla's "Full Self-Driving" (Supervised) system yet, even though the Netherlands already cleared it in April and Denmark followed in June. France wants a single approval process covering all of Europe, with shared testing rules, rather than simply accepting another country's sign-off. Tabarot gave two reasons for holding back: the system lets drivers exceed posted speed limits, and France's own data shows it doesn't keep drivers attentive enough in cities, especially during tricky moves like lane changes, intersections, and roundabouts. He was careful to say France isn't rejecting the technology outright and still supports it in principle. Officials are continuing talks with the Netherlands, other European countries, and Tesla, and a French transport ministry official recently visited the Netherlands to review the underlying data. Tabarot plans to gather France's self-driving industry this autumn to map out next steps. France isn't alone in raising concerns. Sweden recently told the EU it should reject FSD unless Tesla fixes the speeding issue, and other European regulators have voiced similar worries since spring. For homeowners, this doesn't affect any energy upgrades or rebates. It's simply a sign that Tesla's self-driving feature is facing more scrutiny in Europe before it gets a broader green light.
Subaru is delaying the 3-row Getaway EV, following Toyota
Subaru is pushing back production of its new three-row electric SUV, the Getaway EV, following a similar delay from Toyota on its 2027 Highlander EV. Subaru said the pause is meant to allow "final adjustments" before launch, echoing Toyota's earlier statement. The two vehicles share a modified version of Toyota's TNGA-K electric platform and are built at the same Kentucky plant, so the delay isn't a big surprise. Toyota's Highlander delay ran about eight weeks, and the Getaway could see something similar. It was originally expected to start production this fall and go on sale by the end of 2026; it's still expected to arrive in late 2026 or early 2027. For homeowners weighing an EV purchase, this is a car buying story, not a home energy one. Once available, the Getaway is planned to come with a 95.8 kWh battery offering over 300 miles of range, plus a smaller 77 kWh standard model arriving in 2027. It will offer six- or seven-seat layouts, up to 45.6 cubic feet of cargo space, all-wheel drive, 420 horsepower, and fast charging (10% to 80% in about 30 minutes at up to 150 kW) through a standard NACS charging port, the same plug style used by Tesla's Supercharger network. Subaru's newer EVs, the Solterra, Trailseeker, and Uncharted, have been selling well in the US so far this year. The Getaway delay doesn't change any home charging or rebate considerations; it's simply a shift in when this particular model will reach dealer lots.
Tesla says ‘Robotaxi’ is expanding — its own chart shows it’s not
This story is about robotaxis, not home energy upgrades, but it touches on EVs, so here's the gist. Tesla told investors its Robotaxi service is expanding, using a chart showing cumulative paid miles climbing past 2.4 million. But when you look at growth quarter by quarter instead of as a running total, the numbers are flat: Tesla added about 900,000 paid miles in the first quarter of 2026 and the same in the second quarter. No acceleration, just a plateau. Tesla's response to the slowdown has been adding new service areas, including Tampa and Orlando, without saying how many vehicles are in each. But the total active fleet is small, roughly 21 vehicles across Austin, Dallas, Tampa, and Orlando, down from a peak of around 25 in Austin alone back in April. Spreading the same small number of cars across more cities makes the map look bigger without actually increasing how many rides get done. Most of these rides also still have a Tesla employee in the car as a safety monitor, unlike competitor Waymo, which runs driverless rides at much higher volume. For homeowners, this is mainly relevant if you're weighing an EV purchase or watching Tesla as a company. It doesn't change anything about home energy rebates, heat pumps, or weatherization programs. If you already drive an EV, pairing it with home solar remains a separate way to lower fueling costs, unrelated to how the robotaxi rollout is going.
Court Orders EPA to Implement National Soot Standard
A federal court in California has ordered the EPA to move forward with a stronger national air quality standard for soot, the tiny particles (also called PM2.5) that come from sources like vehicle exhaust, power plants, and wildfires and can lodge deep in the lungs. The 2024 standard tightened the limit on how much soot is allowed in the air, but the EPA missed its legal deadline earlier this year to identify which areas of the country don't meet it. The court rejected the agency's attempt to delay further and set a new deadline of February 6, 2027, for the EPA to officially name the areas violating the standard. This ruling doesn't change anything at your house directly, but it matters for the air outside it. Once areas are officially designated as violating the standard, that starts the process of requiring cleanup measures to bring pollution down. An analysis from December 2025 found that 75 million people, about 22% of the country, live in counties whose air didn't meet the new standard under the most recent data at the time. The EPA itself has estimated that fully implementing the standard would save 4,500 lives a year and cut down on asthma attacks, ER visits, and other health problems. For now, this is a legal and regulatory development, not a new rebate or upgrade program. If your area ends up on the violation list once designations are made, it could eventually mean stricter rules on local pollution sources, but any changes tied to your own home's air quality would depend on where you live.
New Pennsylvania Program Offers Free Heat Pump Training
Pennsylvania has launched a new workforce program, Penn Heat Pump Pathways, aimed at training more workers to install heat pumps. The program is funded through the state's Department of Environmental Protection and run by the Building Performance Foundation along with partners TixStone Solutions and CareerEquity. It offers free training, career development help, and assistance with costs like travel, child care, and tools for people entering the field. The goal is to enroll more than 1,600 participants, and the program will run through July 2028. This isn't a rebate or incentive for homeowners directly. It's about building up the number of trained technicians who can install heat pumps, a type of heating and cooling system that moves heat rather than burning fuel to create it. Pennsylvania officials say heat pump demand is growing faster than the workforce that can install them, so this effort is meant to close that gap over the next couple of years. For a homeowner thinking about switching to a heat pump, this news matters mainly as a sign of what's coming: more trained installers in Pennsylvania in the next few years, which could mean shorter waits and more competition among contractors down the road. It doesn't change any rebates or costs available right now, but it's worth keeping an eye on as the program grows, especially if you're in Pennsylvania and planning a heating or cooling upgrade in the next year or two.
What HVAC Contractors Need to Know About the Future of Technician Training
Trane Technologies has opened a large new training center in Davidson, North Carolina, meant to prepare HVAC technicians for equipment that has grown more complex. Company leaders say demand for technicians is rising fast, and the systems they work on now involve more electronics, sensors, and software than in the past. This is background on the industry's workforce, not a program homeowners sign up for, but it helps explain why the technician who shows up at your door may need more training than one from a few years ago. A big driver is the shift to new refrigerants known as A2Ls, which have a lower impact on the climate but require different safety and handling steps than older refrigerants. Homes with newer HVAC systems increasingly use this newer generation of equipment, along with inverter technology, which lets a system's compressor run at variable speeds for better efficiency rather than just switching on and off. Trane says servicing these systems well takes deeper training in controls and diagnostics, not just swapping parts. The company also pointed to artificial intelligence tools that can help technicians diagnose problems faster, and to a growing need for specialists who work on data center cooling systems, a separate but related market. None of this changes what a homeowner needs to do right now. It mainly signals that as home HVAC and heat pump equipment gets more advanced, the industry is working to make sure technicians keep pace with it.
$215B in annual energy cost savings starts with heat pumps: ACEEE
A new report from the American Council for an Energy-Efficient Economy (ACEEE), a research and advocacy group, says the country could cut energy costs by an average of $215 billion a year, adding up to $4.8 trillion by 2050, through a broad mix of efficiency upgrades. The biggest source of those savings: switching homes and buildings from gas furnaces and old electric resistance heating to heat pumps, which heat and cool a home using much less energy. The report estimates this cumulative savings works out to almost $31,000 per household by 2050. The analysis assumes strong policy support, including a full switch to heat pumps for home heating by 2035, driven by incentives and efficiency standards, plus better building design, insulation, and controls in existing homes. About half of the projected 2050 savings would come from buildings, with heat pumps and other efficient appliances as the main driver. The rest comes from industrial efficiency, transportation improvements like better fuel economy and more electric vehicles, and demand flexibility programs that shift electricity use to off-peak times, which the report says could cut peak demand 20% by 2050. The report notes that a federal building performance standard adopted in 2022 was revoked by the Trump administration last year. For homeowners, the broader message is that heating equipment choices, especially replacing an aging furnace with a heat pump, remain the single biggest lever for cutting both energy bills and strain on the power grid in the years ahead.
Report: Only 6 Hours in an HVAC Tech’s Day are Billable
A new industry report looked at how HVAC technicians spend their workday, and the numbers show a lot of time doesn't go toward actual repair or installation work. Out of an average 8.8-hour day, only about 65 percent — roughly 5.7 hours — counts as billable time on the job. The rest gets eaten up by paperwork, training, vehicle upkeep, and driving between jobs, with about 1.13 hours of that driving time not covered by any trip charge. This is more of an inside look at how HVAC companies operate than something that changes what a homeowner needs to do. But it helps explain part of what goes into a service bill. When you schedule a repair or a system checkup, the price you pay is meant to cover more than just the hands-on time at your house — it also factors in the technician's travel, training, and other business costs that don't show up as a separate line item. The report doesn't point to a specific fix or program change for homeowners, and it isn't about rebates, equipment, or new efficiency standards. It's simply industry data on technician scheduling and how field service companies might tighten up their day. If you're getting HVAC work done, the takeaway is mostly context: dispatch delays or driving time can affect how promptly a tech arrives, and that's part of what companies are trying to manage better behind the scenes.
Startup offers low-cost home batteries to Massachusetts residents
A company called Haven Energy has started offering home batteries on a subscription in four counties in southeastern Massachusetts, starting at $29 a month with a 10-year contract. Haven installs a 15-kilowatt-hour battery and keeps ownership of it, which is what keeps the monthly cost low. That's a big drop from buying a battery outright, where a home system can easily cost more than $15,000. Tesla launched something similar last month in Massachusetts and Connecticut, cutting about $30 a month off its existing battery-leasing program. The low price works because the companies, not the homeowner, collect payments from a Massachusetts utility program called ConnectedSolutions, which pays battery owners for sending stored power back to the grid during peak demand, like hot summer afternoons. A typical battery can earn over $1,000 a year this way, and a newer version of the program pays even more in areas where the local grid is congested. Under Haven's plan, customers keep at least 20 percent of stored power on reserve, and the batteries switch to a "safety mode" that blocks grid discharge if a storm threatens an outage, so backup power stays available at home. Homeowners with solar panels can also use these batteries to store daytime solar power for use later. This subscription approach isn't unique to Massachusetts. Vermont's largest utility has offered similar battery leases since 2017, and dozens of states now have programs that pay households for sharing battery power with the grid, a trend that could make backup batteries as easy to sign up for as any other home service.
How to protect residential batteries from heat waves
Home battery systems paired with solar panels are becoming more common, and with that comes new attention to how heat affects them. Batteries work best between 20 and 30 degrees Celsius. Below freezing, they can suffer lithium plating, a buildup on internal parts that hurts performance. Above 40 degrees, they lose efficiency faster, wear out sooner, and in rare cases can overheat badly enough to catch fire, as happened in a recent battery explosion in Germany. If you're considering a home battery, look for one certified to recognized safety standards (IEC 62619, UL 9540, UN 38.3) and carrying the CE mark in Europe, which shows it has passed safety testing. Placement matters too: most residential batteries cool passively, without fans, so they do best in spots with steady temperatures, like a basement or shaded indoor area. Avoid attics or lofts, where trapped heat can build up worse than outside, and keep batteries off sun-exposed terraces or walls. If a good location isn't available, fan-based cooling can help, though it adds noise and maintenance. In some cases, added ventilation or air conditioning around the unit may be needed, though this can eat into the system's overall efficiency. Battery systems already have built-in protection: when temperatures climb too high, they automatically cut back power output, and may shut off entirely if things get critical. During heat waves, running high-power appliances like air conditioners or ovens around midday, when solar generation is highest, lets you use that power directly rather than routing it through the battery, easing heat stress on the system.
Notching and Drilling Joists
This piece explains the building code rules for cutting notches and drilling holes in floor joists, the wood beams that hold up your floor, so plumbers and electricians can run pipes and wires through them. These rules trace back to 1930 and are now part of the International Residential Code. The point is simple: cut a joist in the wrong place or make the hole too big, and you weaken the floor, sometimes enough to cause a permanent sag or a bouncy feel underfoot. The rules boil down to location and size. Notches, cuts into the top or bottom of a joist, are not allowed in the middle third of the span, since that's where bending stress is highest. Outside that zone, notches can't be deeper than one-sixth of the joist's depth or longer than one-third of its depth. At the ends, where joists rest on a wall or beam, deeper notches are allowed because the stress there is different. Holes drilled through the middle of a joist can be bigger and placed almost anywhere, including the center of the span, as long as they stay at least 2 inches from the top, bottom, and other holes or notches. None of this applies to engineered products like I-joists, LVLs, or trusses, which follow the manufacturer's own instructions instead. For an older house, this mostly matters if you're ever having plumbing or wiring rerouted through the floor framing during a renovation, since it affects whether existing cuts are sound or whether new ones can be made safely.
Alternative sealants for poly
This is a forum discussion, not industry news, so there's no policy or program to report on. A homeowner asked what to use instead of acoustical caulk to seal 6 mil poly sheeting to wood, since acoustical caulk is messy to work with. Poly sheeting like this is often used as an air barrier, a layer meant to stop unwanted air leaks in walls, floors, or crawl spaces. Other forum members suggested several alternatives. One person has used Tremco and Loctite polyurethane sealants on both wood and concrete block with no problems, and specifically likes Tremco's Vulkem Max for being less smelly than standard polyurethane sealants. He later clarified he used Loctite's PL line, which includes several sealant types, including one made not to melt foam board, plus various adhesives. He also noted that store-bought tubes can be old stock that's already hardened inside, so checking the manufacture date on the bottom of the tube is worth doing. Another commenter suggested Contega FH as a common substitute with similar sealing properties but less mess and odor. A third mentioned using GreenGlue Sealant, a water-based product that cleans up easily. For a homeowner doing this kind of air sealing work themselves, the takeaway is that there are several off-the-shelf alternatives to acoustical caulk, ranging from polyurethane sealants to water-based options, each with different tradeoffs in smell, cleanup, and cost.
Balcony solar is sweeping the US, but who's actually selling it?
Plug-in solar, sometimes called balcony solar, is catching on across the country. It's a small setup: you hang one or two panels where they get sun and plug them straight into a wall outlet, sending power into your home to offset part of your electric bill. It doesn't need the permits or installer costs of a full rooftop system, which makes it a possible fit for renters or anyone who can't do traditional solar. Utah legalized it last year, and ten more states have passed laws allowing it in recent months, with others considering bills. The catch is that equipment popular in Germany, where this trend started, can't simply be shipped to the US, because the electrical systems differ. A few companies are now selling US-adapted versions. CraftStrom and EcoFlow, both with German roots, have redesigned their panels and added software to meet US electrical codes and state-specific rules, like wattage caps. Bright Saver, a nonprofit, sells lower-cost kits (recent pricing around $285 to $414, plus a $29 membership fee) built from separately certified parts, though its stock has been selling out. Bigger, established solar and off-grid battery brands, including Qcells and Jackery, haven't yet entered the US plug-in market, partly because safety certification for complete systems is still new and electrical code rules are still being finalized. If you're curious about trying this, the options depend heavily on what your state currently allows, so it's worth checking your own state's rules before assuming a product will be legal to use where you live.
