3 practical steps to ensure the US industrial boom runs on electricity

This piece is about factories, not homes, but it touches on where electricity demand and grid costs are headed. A World Wildlife Fund analyst argues that American manufacturers should switch more of their heating processes, currently mostly run on natural gas, over to electric equipment like industrial heat pumps, electric boilers, and thermal batteries (systems that store heat for later use). New analysis cited in the piece estimates this could unlock $254 billion in investment and 1.66 million jobs by 2035, though that is an industry-wide projection, not a guarantee. The author's three suggested fixes are: redesign electricity pricing so factories that shift their power use to off-peak hours get rewarded rather than penalized; help manufacturers cover the upfront costs of swapping out heating equipment through loans, tax breaks, and cost-sharing; and build up domestic supply chains and train more workers to install this equipment. For a homeowner, the direct impact is indirect. If more factories start running on electricity, that adds new demand to the grid. How utilities and regulators handle that demand, including whether they use pricing and flexible scheduling to avoid overloading the system, can affect electricity rates and grid reliability in your area over time. There is no new rebate, program, or deadline here for your own house.

Simple Ventilation for Small Spaces

A new window-mounted ventilator called the SWERV offers fresh, filtered air for renters and owners of small homes who don't have central heating and cooling ductwork. Regular energy-recovery ventilators (ERVs), which bring in fresh air while recovering heat and moisture from the air being pushed out, usually need ducts and wall penetrations, making them costly and impractical for small spaces or rental units. The SWERV skips that entirely: it fits into a single-hung, double-hung, or slider window much like a portable air conditioner, using foam blocks to seal the gaps, and can be installed in minutes without hiring anyone. The unit works by switching the direction of its fan, alternating between pulling stale air out and pushing fresh air in through a single core that recovers up to 80% of the heat and moisture that would otherwise be lost. You can also run it in exhaust-only or supply-only mode if that suits your needs better. Incoming air passes through a washable prefilter plus a second filter (either MERV 8 or the finer MERV 13) to catch dust and particles. The company, SWERVAIR, started a beta program in January 2026. Units are priced at $800 and are designed to cover about 1,000 square feet, roughly the size of a small apartment or house. This could be worth a look if you rent, own a small home, or simply want better air quality without opening up walls for ductwork.

CO2 emissions from US power sector rose 4% last year

Carbon dioxide emissions from the U.S. electric power sector rose 4% in 2025, an increase of 58 million metric tons, according to the U.S. Energy Information Administration. Total energy-related CO2 emissions across the economy rose 2%, or about 115 million metric tons, compared with 2024. The increase was driven by higher electricity demand overall. The power sector generated 3% more electricity than the year before, setting a new annual record, as hot summer weather pushed up demand for air conditioning and set a record for summer peak electricity use. Growing demand from data centers and manufacturing also played a role. Coal-fired generation jumped 13%, adding 78 million metric tons of emissions, while natural gas generation fell 4%, cutting emissions by 23 million metric tons. Wind generation grew 3% and solar grew 34%, which helped offset some of the increase but did not outweigh the rise in coal use. For homeowners, this is mostly background context on where the electricity grid stands rather than something requiring a direct response. It reflects rising demand for cooling and power nationally, and a shift back toward more coal in the generation mix last year. It does not change any rebate programs, incentives, or equipment choices available for home energy upgrades.

Flange in a Flash

Some doors and windows don't come with a built-in flange, the flat lip that normally gets sealed to a house's water-resistive barrier (WRB), the wrap that keeps water out of the wall behind the siding. Without that flange, installers have had to improvise a seal, often with mixed results. Typar has come out with a product meant to solve that: a double-sided tape called FlangeFlash that creates the flange on site. One side of the tape sticks to the door or window before it goes in. Once the unit is set in place, the other side sticks to the WRB, tying the two together into one sealed, mechanically fastened flange. The tape uses the same adhesive formula on both sides, and the outer surface that faces the weather is rated to hold up to a year of sun exposure before it needs to be covered by siding or trim. The product was a finalist for a Most Innovative Building Material award at this year's International Builders' Show. For a homeowner, this matters most if you're replacing windows or doors that don't have flanges, an approach used to fit certain openings or preserve existing trim. A tape like this is meant to give a tighter seal against air and water leaks, and better protection against pests getting in around the frame. FlangeFlash comes in 6-inch by 75-foot rolls for $125 and is sold wherever Typar products are available.

Panasonic’s market exit leads Northeast solar installer to rethink ‘premium’ narrative

Panasonic exited the solar panel and battery business abruptly on April 28, 2025, catching installers off guard, including its former Northeast Installer of the Year, Public Service Solar in New Jersey. If you had Panasonic solar panels or a Panasonic EverVolt battery installed, this is worth knowing about, since the company has stopped making and marketing these products. One practical issue: Panasonic shut down its battery monitoring portal (the app that lets you track how your battery is charging and discharging) in January 2026. That has made service calls more complicated for owners. More recently, Chinese battery brand SolaX took over Panasonic's monitoring apps, and installers are hopeful this will restore normal function. If your battery's app has been acting up or showing outdated information, this ownership change may be the reason, and it may also be the path to a fix. For homeowners still shopping, this story is a reminder that supply chains for solar panels and batteries have been unsettled, with manufacturer shortages, factory fires, and shipping delays affecting availability of premium brands. Installers have been switching between suppliers like REC, Maxeon, and FranklinWH to keep projects moving. None of this changes what a solar system already on your roof does, but it may affect what brand your installer offers if you're getting a new system or adding battery storage now.

Solar contractors service arrays after original installers shutter

If your solar panels were installed by a company that has since gone out of business, you're not stuck. Some homeowners end up with "orphaned" systems when their original installer shuts down, leaving no one to fix faulty parts, finish setup, or honor warranties. A number of solar contractors have started taking on these customers as outside clients, even though they had no hand in the original install. Two examples: Atma Energy in San Antonio, Texas, and Green Power Energy in Annandale, New Jersey, both began accepting orphaned systems in the past few years as inquiries picked up. They offer phone troubleshooting and, if needed, send a technician to inspect the array, fix faulty equipment, complete unfinished commissioning (the final steps that get a system officially up and running), or help homeowners work through warranty claims. In some cases, issues can be resolved entirely over the phone at no cost. Green Power Energy also offers an annual check-up plan that reviews how the system is performing and helps homeowners understand what to look for on their utility bills. This kind of service is becoming more common as market conditions push some installers out of business. If your system's original installer is no longer around, it's worth checking whether another local solar contractor offers this kind of outside maintenance or repair support, since availability and offerings can vary by company and location.

Research at Risk: The Latest Proposal to Devastate the National Science Foundation

This story is about federal science funding policy, not home energy programs, so it doesn't touch energy-efficiency upgrades or rebates directly. It's included here because it involves a federal agency, but nothing in it changes what's available to homeowners working on insulation, heat pumps, or weatherization projects. The piece describes proposed changes to how the National Science Foundation (NSF) awards research grants. NSF is the main federal agency that funds basic science and engineering research across universities, using a merit-review process meant to be independent of politics. Under new draft rules open for public comment through August 24, a politically appointed official could review and reject grants for not aligning with an administration's priorities, and could even cancel already-awarded grants. Separate proposals would stop NSF funding from covering travel to scientific conferences or publication costs, and would sharply restrict collaboration with researchers from certain countries, including China. None of this affects home energy rebates, heat pump incentives, or weatherization assistance, which run through different programs and agencies. If you're evaluating an energy upgrade for your house, this news has no bearing on your options or deadlines. It matters mainly for how federal research money gets distributed and whether political appointees, rather than scientific review, decide which studies get funded.

US data center electricity use could more than double to 426 TWh by 2030: report

Data centers built to run AI and other digital services are using a fast-growing share of the country's electricity and water, according to a new report from the Kansas Health Institute. US data centers used an estimated 183 terawatt-hours of electricity in 2024, more than 4% of total US electricity use, and that figure could more than double to 426 terawatt-hours by 2030. Right now, the power running these facilities comes 56% from fossil fuels, 22% from renewables, and 21% from nuclear. Water use is climbing too. Data centers directly used about 17 billion gallons of water in 2023, and that could double or quadruple by 2028. One in five US data centers already sits in an area with water stress. The report warns that this growth is delaying coal plant closures and slowing state and local efforts to shift to cleaner power, since renewable supply isn't keeping pace with demand from both data centers and existing electricity users. For homeowners, this doesn't change anything about your house directly, but it's part of the backdrop behind rising demand on the grid and growing debate over who bears the cost and environmental impact of new data center construction. New York recently became the first state to pause large data center construction for a year while it studies the effects. Other states and local governments are responding differently, some focused on economic development, others on zoning, land use, and protecting local resources, so what this means where you live will depend on your state and community.

When Sears Sold Houses

From 1908 until the early 1940s, Sears sold complete house kits by mail. Customers picked from hundreds of designs, and Sears shipped everything needed to build the home, right down to nails, paint, and precut, numbered lumber, to the local train station. Roughly 30,000 parts arrived with a detailed instruction manual, and Sears claimed about half of these homes were built by the owners themselves rather than hired carpenters. The company left out plumbing, heating, and electrical wiring as add-ons, mainly because many areas didn't yet have electric or municipal water service, not to cut costs. The program fell apart with the Great Depression. Sears had been financing many of these homes with loose mortgage terms, and when buyers defaulted after the 1929 crash, Sears ended up foreclosing on thousands of houses, a move that badly damaged its reputation. The company stopped offering mortgages in 1933 and shut down the kit-home program entirely by the early 1940s. Cheaper post-war tract housing, built on-site by production crews rather than by homeowners, eventually replaced the appeal of kit homes altogether. An estimated 18,000 to 22,000 Sears kit houses are still standing today. If your house was built in the early 20th century, it is worth knowing that these homes often used solid, durable materials, especially the higher-end "Honor Bilt" line, which used tighter framing spacing and rot-resistant wood. Sites like searshouses.com list models and offer ways to check whether a house matches an original Sears design.

Companies are making hard choices on sustainability commitments

A new survey of sustainability professionals at large companies (those with more than $1 billion in annual revenue) finds that many corporations are pulling back on climate and sustainability pledges. Of the 124 professionals surveyed, 71 percent said one or more of their company's sustainability commitments could be scaled back, and fewer than a quarter expect all current commitments to stay in place. The commitments most likely to be cut are those tied to diversity, equity and inclusion (DEI) programs and public advocacy on sustainability policy. Supply chain requirements, climate transition investments, nature and biodiversity goals, and human rights due diligence were flagged less often as at risk. The survey suggests companies are shifting from broad sustainability agendas toward a narrower set of priorities, driven by tighter budgets, more regulation, and pressure to show that sustainability work pays off in business terms. For homeowners, this is background context rather than something that changes any specific program. It does not affect rebates, tax credits, or incentives tied to home energy upgrades like heat pumps or insulation, which typically come from government programs rather than corporate pledges. It's more a signal of how corporate priorities around climate and sustainability are shifting broadly, which could eventually shape things like product offerings or corporate-funded incentive programs, but no direct impact on home energy costs or upgrade programs is described here.

EV Sales Rebound In Trump’s Nemesis, The Entire State Of California

Electric vehicle sales in California picked up in the second quarter of 2026, even without the federal $7,500 EV tax credit that expired last September. The state's Energy Commission reports that new zero-emission vehicles, a category that includes battery EVs, plug-in hybrids, and hydrogen fuel cell cars, made up 19.1% of new vehicle sales, up 3.3 percentage points from the prior quarter. Of the 86,857 new ZEVs sold, most were full battery EVs. Rising gas prices, tied to a war between the US and Iran that began in late February, appear to be pushing more buyers toward electric. If you're shopping for a car and thinking about going electric, California has a new incentive worth knowing about. Starting next month, the state's MyFirstEV program will offer first-time EV buyers a $3,500 rebate at the dealership on new vehicles priced up to $50,000, and $1,750 on used EVs up to $25,000. The rebate applies at purchase, so you would not need to wait for tax season to see the savings. Automakers taking part include Ford, GM, Honda, Hyundai, Kia, Lucid, Mitsubishi, Nissan, Rivian, Subaru, Tesla, Toyota, and Volvo. This news is specific to California. The federal tax credit is gone nationwide, so if you live elsewhere, any EV incentives available to you now depend entirely on what your own state offers. It's worth checking your state's current programs directly, since rules and rebate amounts vary widely and change often.

Crusoe’s latest deal targets power electronics for grid reliability

AI infrastructure company Crusoe is partnering with ON.energy to install five gigawatts of backup power equipment at its data center campuses, including its Stargate site in Abilene, Texas. The equipment, called a UPS (uninterruptible power system), sits between a data center and the power grid and acts as a buffer, smoothing out the huge, rapid swings in electricity demand that AI computing creates. This matters for grid reliability because data centers training AI models ramp their power draw up and down in sudden bursts, which can stress the grid. Worse, when there's a voltage problem, data centers can suddenly disconnect entirely, which drops a large amount of demand all at once and can damage grid equipment. This already happened in Virginia in February 2025, when a power line problem caused 40 data centers drawing about 2 gigawatts to switch to backup power simultaneously. Incidents like this led a national grid reliability organization to issue a rare warning in May about the risks data centers pose to the power system. The new equipment is designed to prevent these swings and sudden disconnections from reaching the grid, and it's built to meet new rules from the Texas grid operator requiring large power users to "ride through" disturbances rather than dropping offline. For homeowners, this kind of technology doesn't change your utility bill directly, but it's part of a broader effort to keep the grid stable as data centers add unprecedented amounts of new electricity demand in many regions.

Pennsylvania passes law establishing solar decommissioning plans

Pennsylvania has a new law covering large solar projects, the kind built on leased farmland or open land rather than home rooftops. Governor Josh Shapiro signed Senate Bill 349, which requires solar projects of 2 megawatts or larger to have a decommissioning plan, essentially a plan for tearing down the panels and restoring the land once the project stops operating. Under the law, project owners must give landowners a decommissioning plan within 30 days of starting construction, then update it every five years. If a project goes inactive, it has to be fully removed within 18 months unless it's being restarted. Removal means taking out the solar equipment and any access roads built for it, and returning the land to something close to its condition before construction, including replacing topsoil. If a company skips providing a plan, whoever started the project has to pay the landowner the estimated cost of decommissioning instead, with that cost checked periodically by outside engineers. The law also bars using solar components made with forced labor, under existing federal rules. This mainly affects landowners who lease acreage to solar developers, not homeowners with rooftop panels. But it is a sign that states are paying closer attention to what happens when large solar farms age out or shut down, making sure land gets cleaned up and restored rather than left with abandoned equipment.

Chevy and Cadillac essentially have no new EVs planned as GM shifts back to gas

GM is pulling back on new electric vehicles from Chevrolet and Cadillac, shifting more attention back to gas-powered models over the next few years. Cadillac, which had planned to sell only electric vehicles by 2030, will bring updated gas versions of the CT5 sedan, XT5 SUV, and three-row XT6 SUV starting next spring. These will be sold alongside Cadillac's current electric SUVs. Chevrolet is also adding new gas models. Its Bolt EV will stop production at the end of the year and be replaced by a gas-powered crossover built in Kansas. The Equinox EV, Blazer EV, and Silverado EV will stay on sale, with possible updates to the Blazer and Equinox reported for 2028, though GM hasn't confirmed that. For homeowners who also think about their next car alongside home energy upgrades, this means fewer new electric options are coming soon from two of the more affordable, widely available EV brands. GM has recorded $10.9 billion in costs tied to its EV pullback since late 2025, and it raised its profit outlook for the year despite that. Meanwhile, competitors like Hyundai, Toyota, and others are expanding their electric lineups and battery production, so buyers interested in an EV will likely see more choices from other automakers even as GM's electric offerings stay largely the same for now.

Fortress Power partners with Flip Energy for VPP programs

Battery maker Fortress Power is teaming up with Flip Energy to connect more home battery systems to virtual power plant (VPP) programs. A VPP is a setup where utilities pay owners of home batteries or other energy storage to share some of that stored power with the grid during times of high demand, in exchange for money or bill credits. Flip Energy runs the software platform that lets battery makers, utilities, and other partners coordinate these programs. Fortress Power batteries already take part in 12 VPP programs around the country, including LUMA's Clean Energy Program in Puerto Rico and Rocky Mountain Power's Wattsmart Battery Program. The new partnership with Flip Energy is meant to strengthen those existing connections and make it easier to add more programs in the future, giving battery owners more ways to earn money from systems they've already installed. For a homeowner, this mainly matters if you already own, or are considering, a Fortress Power battery. It signals that more utility programs may become available to plug into over time, potentially adding another source of savings or payments beyond what the battery already provides for backup power or reducing your own electric bill. No specific new program, payment amount, or enrollment deadline was announced here, so if you have a Fortress Power system, it's worth keeping an eye out for updates on which VPP programs are available in your state.

Freak storm forces Arizona contractor to rebuild just-completed carport

A microburst that hit Tempe, Arizona in October 2025 destroyed a solar carport just days before it was set to be handed over to its owner. A microburst is a sudden downward blast of air that spreads out at ground level, causing damage similar to a tornado. This one likely brought winds over 100 mph, well beyond the 105-mph standard the structure was built to withstand. The storm twisted metal supports, broke solar panels, and damaged fencing, though the foundations held up. The contractor, Obodo Energy Partners, worked with structural engineers and its insurer to sort out what happened. Because the system hadn't officially been transferred to the customer yet, it fell into a gap between the contractor's insurance and the owner's property insurance. The two sides ended up splitting the cost of repairs and rebuilt the carport. For the rest of that customer's planned six-carport project, they agreed to build the remaining systems to withstand higher winds than before. For homeowners, the takeaway is less about solar carports specifically and more about what can happen with any home energy project in the window between finishing construction and having insurance coverage take effect. If you're having solar panels, a carport, or similar equipment installed, it's worth knowing when ownership and insurance coverage officially transfer to you, since that timing can matter if severe weather hits before the paperwork is complete.

Ohio solar developer braves 2 snowstorms to win school contract

A Cincinnati-based solar company, National Energy Control (NEC), won a contract to install solar panels, EV chargers, and new roofing across 21 school buildings for the East Orange School District in New Jersey. The company found the project through a public request for proposals and put together its bid despite two separate snowstorms that disrupted travel and even delayed the shipment of the bid package itself. The company ended up hand-delivering the paperwork to make the deadline. The school district broke ground on the project in June, and the planned solar installation has grown to 5.85 megawatts of output. The project bundles solar power with roof repairs and EV charging for the district's electric school buses, an approach where one contractor handles multiple building upgrades together rather than separately. For a homeowner, this story is mostly a behind-the-scenes look at how a school district project like this gets built, rather than something with a direct action for your own house. But it's a reminder that solar, roofing, and electrical work are increasingly bundled together in larger projects, and that public buildings like schools are a growing part of the solar market. If your own home needs a new roof and you're considering solar, pairing those projects is a similar idea, and it may be worth asking installers in your area whether they handle both roofing and solar together, since combining the work can sometimes simplify permitting and financing.

Chicago contractor installs solar system fit for a president

The Obama Presidential Center, which opened this June in Chicago's Jackson Park, runs entirely on renewable electricity and includes its own rooftop solar array. Chicago-based installer Windfree Solar put 513 panels across the roof of Home Court, an athletic and events building on the campus, adding up to a 228-kilowatt system. The building itself is heated and cooled mainly with geothermal energy, and its roof was designed with solar in mind from the start, though Windfree widened the spacing between panel rows during installation to make future maintenance easier. The array was finished in December 2025. For homeowners, this isn't a story about a program or rebate you can apply for. It's a look at how solar and geothermal systems get paired together on a large, high-profile building, and how even a rooftop designed for solar can still need adjustments once an installer gets into the details of actually servicing the panels over time. The project also reflects Chicago's broader push to bring solar work into underserved communities. Windfree is registered as an Equity Eligible Contractor under the state's Illinois Shines program and hires through job-training programs on the South Side, where the presidential center sits. That's a detail specific to Illinois' solar incentive structure, so homeowners elsewhere curious about similar equity-focused solar programs should check what their own state offers.

FERC fails to shield PJM consumers from data center transmission costs: ratepayer advocates

Federal regulators are facing pushback over a plan meant to keep everyday electric customers from covering the grid costs of new data centers. Last month, the Federal Energy Regulatory Commission (FERC) told PJM Interconnection, the grid operator for 13 Mid-Atlantic and Midwestern states plus Washington, D.C., that its rules for connecting large power users like data centers to the grid appeared unfair, partly because regular households may be footing part of the bill for transmission upgrades those data centers require. Now ratepayer advocates from Delaware, Illinois, Maryland, Ohio and Pennsylvania say FERC's order doesn't go far enough. They argue it fails to fix how costs for grid upgrades get spread across a whole region, meaning households could still end up paying for infrastructure built mainly to serve data centers. The advocates want FERC to require that data centers cover the full cost of any upgrades needed to connect them, and to act quickly, since PJM has 60 days to respond to the original order, with a possible 90-day extension. For homeowners in PJM's territory, this is a dispute about who pays for the wires and equipment upgrades driven by the data center boom, not something with an immediate bill impact. But it's worth watching: if these advocates don't succeed in tightening the rules, the added transmission costs from data center growth could eventually show up in electric rates for ordinary customers in these states.

Pennsylvania Passes Solar Decommissioning Legislation to Ensure Sustainable Energy Development

Pennsylvania Governor Josh Shapiro has signed Senate Bill 349, a new state law covering what happens when large ground-mounted solar farms reach the end of their useful life. The law sets statewide rules for decommissioning these projects and makes clear that the solar companies building them, not the landowners who host them, are responsible for cleaning up and removing the equipment when a project is finished. For most homeowners, this law is about big solar farms built on leased land, not rooftop solar panels on houses. If you own land that a solar developer wants to lease for a utility-scale project, this gives you some protection: the developer, not you, will be on the hook for removing panels, wiring, and other equipment down the road, and the state now has clear expectations written into law rather than case-by-case agreements. The bill passed with support from both parties, and the solar industry's national trade group, the Solar Energy Industries Association, praised it as a common-sense measure that balances landowner protections with clear rules for developers. There's no new rebate, incentive, or program here for homeowners installing rooftop solar or making other energy upgrades. It's a regulatory change aimed at how Pennsylvania manages the lifecycle of large solar installations, which may matter to you mainly if you're weighing a land lease offer or simply want to know how the state is handling the long-term footprint of solar development in your area.

Solar and Storage Industries Institute adds Pawlenty, Jones-Albertus to board of directors

A nonprofit research group tied to the solar industry, the Solar and Storage Industries Institute (SI2), has added two new members to its board of directors: Tim Pawlenty, former Minnesota governor and now head of the Solar Energy Industries Association, and Dr. Becca Jones-Albertus, a former U.S. Department of Energy solar official now working at Exelon. SI2 says it plans to grow its national research work on solar and battery storage as the industry changes. This is mostly an inside-industry personnel move rather than something that changes costs, rebates, or rules for homeowners right now. SI2 studies things like permitting, interconnection, solar affordability, and public attitudes toward solar and storage, research that can eventually shape state and local policy on things like rooftop solar rules or utility programs. Jones-Albertus previously worked on efforts to lower the "soft costs" of solar (the non-equipment costs like permitting and installation labor) and to strengthen the U.S. solar supply chain. There's no new program, deadline, or rebate here for homeowners to act on. It's a sign that the group producing research behind future solar and storage policy is expanding its leadership, which could influence how affordable and accessible solar and storage options become over time, but nothing changes for your home today.

BNEF nearly doubled its forecast for US data center power demand

A new forecast from BloombergNEF says U.S. data centers could need 194 gigawatts of power capacity by 2035, nearly double what analysts expected as recently as December. That would mean data centers use about 20% of all U.S. electricity by the mid-2030s, up from under 6% today. The forecast keeps climbing because more projects, many run by companies new to the business, are entering the pipeline. But analysts caution these plans face real hurdles: labor and equipment shortages, slow grid hookups, and local opposition. Some counties are seeing packed public meetings where residents object to rezoning for these projects. Fifteen states have considered temporary bans on new data center construction, and New York's governor recently signed the first statewide pause, giving regulators up to a year to write rules meant to protect utility customers, the environment, and the power grid. Despite the pushback, big tech companies plan to keep spending heavily, an estimated $700 billion this year among Amazon, Google, Microsoft, and Meta. For homes, the relevant piece is the grid strain. Most data centers still plan to connect to the regular power grid rather than go fully independent, since running your own power plant is harder than it sounds. Many developers are instead building on-site gas plants as a stopgap while waiting for grid connections, and some of these gas projects have already run into performance problems. As this demand grows, it could affect local electricity capacity and rates, so it's worth keeping an eye on what your state and utility decide about data centers in your area.

Chevy and Cadillac scale back EV plans as GM shifts to gas

General Motors is pulling back on electric vehicles and putting more gas-powered models back into its lineup. Cadillac, which had planned to sell only electric vehicles by 2030, will bring new gas-powered versions of the CT5 sedan, XT5 SUV, and XT6 SUV starting next spring. These will sell alongside Cadillac's current electric SUVs rather than replacing them. Chevrolet is making a similar shift: the Bolt EV will stop production at the end of this year, and GM plans to replace it with a gas-powered crossover built in Kansas. Not every electric Chevy is going away. The Equinox EV, Blazer EV, and Silverado EV remain on sale, and GM says updates to the Equinox and Blazer could come as soon as 2028. All of GM's 2027 electric models, including the Equinox and Blazer, are switching to the NACS charging port, the connector standard Tesla uses, which is becoming common across the industry. GM says it still has other electric vehicles in development but is being cautious given competition in the US market. For homeowners, this is mostly a signal about where the car industry is headed rather than something that changes your own upgrade plans. If you're weighing an EV purchase alongside home projects like a charger install, it's worth knowing that GM's near-term electric lineup will grow more slowly than before, while rivals like Hyundai and Toyota continue expanding their own electric offerings.

The Boathouse

This is a house tour piece, not an energy-upgrade story, but it's worth noting for anyone renovating an older home near water. A 1920s beach cottage on Puget Sound in Seattle got a third-floor addition designed to hold up to salt air and coastal weather while opening up to the outdoors. The 800-square-foot addition adds a primary suite and office, with a semi-enclosed deck that uses sliding doors, louvered screens, and a roll-down exterior shade to blend indoor and outdoor space. The design leans on marine-inspired details like porthole windows and a built-in bench that folds out into a bed. For durability against saltwater conditions, the builders swapped wood railings for powder-coated aluminum ones made to match the home's original look, since wood breaks down faster in that environment. They also used ipé decking, a dense hardwood known for holding up outdoors, installed over a waterproof membrane roof.

This huge US e-waste deal could unlock rare earths for EVs

Two recycling companies, ERI and Cyclic Materials, have teamed up to pull rare earth minerals and other valuable metals out of old electronics on a large scale. ERI, based in Fresno, California, will collect and sort e-waste through its eight US recycling centers, using software that can identify which products contain rare earth magnets. Those materials will then go to Cyclic Materials' plant in Mesa, Arizona, which can process up to 25,000 metric tonnes of end-of-life components a year and recover rare earths along with copper and aluminum. Rare earth magnets are used in electric motors for EVs and in wind turbines, and demand for them is also rising because of AI and other advanced manufacturing. Right now the US relies heavily on imported rare earths, and recycling old electronics is seen as a faster way to build a domestic supply than opening new mines. This partnership aims to turn discarded electronics, most of which currently get thrown away without recovering these materials, into a steady source of minerals for US manufacturers. For homeowners, this isn't a program to sign up for or a rebate to claim. It's a supply-chain deal that could, over time, help ease the shortage of rare earth materials used in EVs and clean energy equipment. The companies haven't said which specific products they'll target yet or given a timeline for when recycled materials will start reaching manufacturers, so any effect on EV prices or availability would show up later, not immediately.

The Growing Market for Altitude Simulation Systems

A Colorado company called Altitude Control Technology, based in Edwards, has developed systems that adjust indoor air to ease the effects of high elevation. Towns like Aspen, Vail, Telluride, and Breckenridge sit above 8,000 feet, where the air holds less oxygen than at sea level. That thinner air can cause dizziness, nausea, shortness of breath, and trouble sleeping, especially for visitors and part-time residents who aren't used to it. The company's founder explains that oxygen makes up the same 20.9% of air everywhere, from sea level to Mount Everest. The difference at altitude is that there's simply less air overall, so each breath brings in fewer oxygen molecules. Rather than relying on portable oxygen concentrators or breathing tubes at night, the company's systems are built into a home to adjust the air homeowners breathe indoors, aiming to reduce altitude-related discomfort without medical equipment. For homeowners in or considering a home in Colorado's high mountain towns, this points to a growing category of building systems aimed specifically at altitude, alongside standard energy-efficiency upgrades. The company has been in business for three decades and originally served residential, commercial, and industrial customers, and is now expanding into hospitality settings like hotels. If you own or are building a home at high elevation, this kind of system is worth knowing about as an option, though details on cost and how the technology works were not covered here.

Hillside Haven

This is a design feature about a house near Canyon Lake, Texas, built into a steep hillside. Rather than raising the house on stilts, the architect cut a flat terrace directly into the slope, using limestone retaining walls to hold back the earth. That let the house open onto a sheltered outdoor space with wide views, instead of sitting up on posts. The design was shaped by the harsh local climate. A standing-seam metal shed roof shelters large windows in the main living area and extends outward to create a shaded patio, cutting down on heat gain. The kitchen and two bedrooms sit in separate small volumes the architect calls "cabin pods," across from the main living space. The most unusual choice is that the builders left the structure exposed rather than covering it up. Framing, roof trusses, and polycarbonate wall panels are visible inside, showing how the house is put together. Even the ceiling, made of perforated pegboard, does double duty: besides its look, it helps absorb sound echoes in a room built mostly of concrete and steel. This is a one-off custom project, not a program or product you can sign up for, so there is no rebate or deadline tied to it. It is worth noting mainly as an example of how a home can be designed around a difficult, sloped site and a hot climate using shading, an efficient roof shape, and site-specific construction choices, ideas that could be relevant for anyone building or renovating on similar terrain.

Inside Amazon's approach to data center sustainability: A conversation with Brandon Oyer

This is a sponsored piece from Amazon about how the company builds and powers its data centers, not something with direct steps for your own home. Amazon says it pays the full cost of electricity and grid upgrades (new transmission lines, substations) needed for its data centers, rather than passing those costs to other customers' bills. It points to examples in Indiana, where utility Indiana Michigan Power cut base rates for customers after gaining revenue from large users like Amazon, and Mississippi, where utility Entergy plans to invest an extra $300 million in grid improvements at no added cost to customers, aiming to cut power outages in half over five years. Amazon also discusses its energy mix and water use. It says it buys carbon-free power from more than 700 projects worldwide, totaling 42 gigawatts, and is investing in small modular nuclear reactors, including a $500 million stake in a company called X-energy. On water, Amazon says it has cut its water use per unit of computing by 52% since 2021 and is 75% toward a goal of using more water than it consumes by 2030. It highlights projects like precision irrigation for Mississippi farmers, meant to save 150 million gallons of water a year, and a $235 million investment in Oregon surface-water systems that will mostly serve nearby communities, not just Amazon facilities. For homeowners, the main relevance is regional: if a large data center is planned or built near you, these are the kinds of grid and rate commitments companies like Amazon say they're making, and it may be worth watching how your own utility handles similar large customers.

Cancer diagnosis leads one woman to solar co-op and competitive boating

This is a profile piece rather than news about energy programs or rebates, so there's nothing here that directly affects a homeowner's own upgrade plans. It's a personal story about Rachel Levey, who works at PV Squared, a worker-owned solar installation cooperative in Massachusetts. Levey took the job at PV Squared in 2017 while undergoing chemotherapy for breast cancer, after deciding she wanted work that felt meaningful rather than "extractive and wasteful." She now serves as the cooperative's sales and service specialist, helping customers with system troubleshooting and explaining incentives and equipment, while also sitting on the board and building in-house software for the company. Outside of work, Levey found dragon boat racing, a sport that has become popular among breast cancer survivors because the paddling motion helps with recovery. She coaches a team on the Connecticut River and competed for the U.S. national team at the World Dragon Boat Racing Championships in Germany, where her team won silver and bronze medals. She is training for next year's championship in Hong Kong. The story doesn't cover any rebate programs, incentives, or technical details relevant to home solar or energy upgrades. It's a human-interest feature about one installer's personal journey into the solar industry.

Indiana solar developer supports agriculture after REAP grants wane

In August 2025, the U.S. Department of Agriculture tightened eligibility rules for its Rural Energy for America Program (REAP), which had been giving farms and small businesses cash grants covering half the cost of a solar or wind project. Those grants, boosted by the Inflation Reduction Act, had made solar payback times as short as one to two years for some farms in the Midwest. Indiana-based installer HSI Solar says the changes have already slowed demand in the agricultural market. The company has helped its customers secure nearly $3.5 million in REAP grants over time and is now working to make sure people who were promised funding still get it as the program winds down. Rather than walking away from farm customers, HSI shifted its approach: instead of mainly explaining solar's benefits to farmers, it is now meeting with groups like the Rural Land Use Council and the Dairy Sustainability Alliance to understand farmers' current concerns, and talking with Indiana's energy secretary and USDA director. For a homeowner, this is less about a direct program change and more a sign of how federal solar incentives can shift quickly. If you or someone you know runs a farm or small business that was counting on a REAP grant, it is worth checking directly with USDA or a local installer on current eligibility and funding status, since rules have changed and support is not guaranteed at the levels it once was.

35.5%! LONGi Once Again Breaks World Record for Crystalline Silicon-Perovskite Tandem Solar Cell Efficiency

The solar panel maker LONGi has set a new efficiency record for a type of solar cell that stacks two light-absorbing layers together instead of one. These "tandem" cells pair standard crystalline silicon with a material called perovskite, letting the panel capture more of the sun's energy than a typical single-layer silicon cell can. LONGi's latest version converts 35.5% of sunlight into electricity, certified by an independent European testing lab. Most silicon panels on the market today top out well below that, since a single-layer cell has a hard physical ceiling of around 33.7% efficiency. This tandem approach has a theoretical limit as high as 43%. This is a lab result, not a shipping product. LONGi has been climbing steadily toward this number over the past couple of years, and it has also tested the technology on larger, more industrial-sized cell samples and on assembled tandem panels, with lower but still strong efficiency numbers in those bigger formats. That gap between small lab records and full-size manufactured panels is normal for new solar technology and usually takes years to close. For a homeowner, the practical takeaway is simple: this is an early signal that future solar panels could squeeze more power out of the same roof space, which would matter for anyone with a small or shaded roof where every bit of panel efficiency counts. But panels using this technology are not yet available to buy, and no timeline for that was given.

Minnesota solar project set to replace retiring coal plant reaches 710 MW

Xcel Energy has finished the third phase of its Sherco Solar project in Becker, Minnesota, built on the site of a coal plant that is retiring. With three phases now running, the project generates 710 megawatts of power. A proposed fourth phase would push total capacity to 910 megawatts by 2029, enough to power more than 190,000 homes. Xcel says the expansion would also create about 300 union construction jobs and $90 million in local economic benefits. This is a utility-scale project, not something that changes rebates or programs available to individual homeowners. But it does reflect a broader shift happening in Minnesota and other states, where aging coal plants are being replaced with solar and other renewable sources to supply the regional power grid. Over time, that kind of shift can affect the mix of electricity reaching your home and how utilities price and manage power, though this project itself does not come with any direct action or benefit for homeowners to sign up for. If you are curious about how your own state's energy mix is changing, or whether similar projects are planned near you, it may be worth checking with your local utility or state energy office for specifics.

Inside Amazon's approach to data center sustainability: A conversation with Brandon Oyer

Amazon shared details on how it plans and pays for the massive data centers it needs to run AWS and its AI services. A company energy executive described how Amazon picks data center locations partly based on where added electricity demand can most help the broader grid, and said Amazon covers the cost of the power it uses plus the transmission lines, substations, and other grid upgrades needed to serve its facilities. Amazon has also signed a White House pledge committing to cover these costs rather than pass them to other electricity customers. The company points to some early results: in Indiana, the utility Indiana Michigan Power cut base rates for customers, citing new revenue from large customers like Amazon. In Mississippi, Entergy plans $300 million in grid upgrades at no extra cost to customers, funded partly by Amazon's business, with a goal of cutting power outages in half over five years. Amazon is also investing in nuclear power, including small modular reactors, as part of its carbon-free energy mix. On water, Amazon says it has cut water use at its data centers and increasingly uses treated wastewater instead of drinking water for cooling. It's also funding water projects elsewhere, including irrigation upgrades for Mississippi farmers and two water-supply projects in Oregon meant to reduce reliance on groundwater. None of this requires anything from homeowners, but if you live near a utility territory where Amazon is building data centers, it's worth watching your own utility's rate filings, since these deals can affect what shows up on local electric bills.

2026 Top Solar Contractors List showcases veterans of dominant energy industry

An industry publication has released its 15th annual list ranking the top solar and energy storage installation companies across the country. The U.S. has now passed 6 million individual solar installations, and solar remains the most-installed source of new electricity. Most companies on the list are experienced, with over 72% having at least 10 years in solar work. For homeowners, the notable trend is on the residential side: more listed companies are doing residential work than in any previous year, and the "installer" category grew 10%, meaning more of these top companies are completing smaller, non-utility jobs like home solar systems rather than only large commercial or utility projects. California, Illinois, Texas, New York and Pennsylvania remain the top states for installations, while Maryland, Ohio and Wisconsin saw notable growth in both large-scale and residential markets. A survey of these companies found that half of residential installers are primarily doing direct-ownership projects this year, meaning the homeowner owns the system outright, while 21% mainly offer third-party ownership arrangements, and the rest do a mix of both. None of this changes any specific rebate or incentive available to you, but it does suggest that if you're considering solar, there are more experienced companies actively working in the residential market than in past years, and ownership options like direct purchase versus third-party arrangements are both common paths installers are offering.

Groups Take First Step Toward Lawsuit Against TVA Over Clean Air Act Violations at Kingston Site

Environmental groups are moving toward suing the Tennessee Valley Authority over air pollution violations at its Kingston power plant site in Tennessee. The Southern Environmental Law Center, representing Appalachian Voices and the Sierra Club, sent TVA a formal warning letter this week arguing that construction of a new gas plant next to the aging Kingston coal plant breaks the Clean Air Act. TVA had planned to retire the coal plant, one of its dirtiest and least reliable, but reversed that decision in February and now intends to run both the coal and gas plants at once. Running both plants together requires a stricter "major source" permit, which would force TVA to study the combined pollution and install modern pollution controls. Instead, TVA is building the gas plant under a weaker "minor" permit while spending more than $636 million to keep the old coal plant going. Combined, the two plants could release thousands of tons of pollution a year, including nitrogen oxide, sulfur dioxide, carbon monoxide, and fine particulate matter, pollutants linked to asthma, heart disease, and other health problems. Groups say the costs of keeping the coal plant running, along with building the gas plant, will show up on household power bills for TVA customers in the Tennessee Valley. This is a required legal step before a lawsuit: TVA now has 60 days to fix the violations, or the groups can take the utility to court. A similar warning was sent to TVA last month over its Cumberland plant in Cumberland City, Tennessee.

Idaho just switched on a big solar farm – and a much larger one is next

Idaho has switched on a new solar farm, Pleasant Valley Solar 2, generating 125 megawatts, and construction has begun on a much bigger project nearby, the 400-megawatt Blacks Creek Energy Center in Ada County. Together the developer, rPlus Energies, has now built or contracted more than 1 gigawatt of solar and battery storage in the state, representing over $750 million in investment. Idaho gets most of its power from hydropower dams, but solar is growing. As of June 2026, the state had 1,301 megawatts of solar installed, ranking 34th in the country, and solar now supplies about 9 percent of Idaho's electricity. Idaho Power, the state's utility, is buying power from these projects to help meet rising demand. For homeowners, this news is mainly about the state's broader electric supply rather than anything you need to do at your own house. More solar and battery storage on the grid can mean more reliable power and, over time, help keep electricity costs in check, since these plants add generation without needing new fuel. The projects are also funding workforce scholarships at Boise State University and the College of Western Idaho to train future energy workers, and they generate tax revenue for local governments through Idaho's solar energy tax. None of this changes rebates or incentives for putting solar panels on your own roof, but it shows the state's energy mix is shifting to include more solar alongside its traditional hydropower.

GM just added ChargePoint to its EV apps

This is EV charging news, not a home energy upgrade story, but here's what changed: GM has added ChargePoint to its Energy Pass app, which works inside the myChevrolet, myGMC, and myCadillac apps. If you drive a GM electric vehicle, this means you can now find, start, and pay for charging at ChargePoint stations directly through your car's own app, instead of setting up a separate ChargePoint account. ChargePoint runs close to 80,000 public charging spots in the US, including about 75,000 slower Level 2 chargers (the kind that take a few hours) and more than 4,400 DC fast chargers (which charge much quicker, often used on road trips). Many of these stations also support "Plug & Charge," meaning you just plug in and the car and charger handle payment automatically, no app tapping required. GM says that as it adds more charging networks to Energy Pass, GM drivers should eventually be able to reach around 70 percent of all DC fast chargers in the country and about 60 percent of public Level 2 chargers, all from one app. For homeowners who drive a GM EV and charge at home most of the time, this mainly matters for trips or backup charging away from the house, since it means fewer apps to juggle and easier access to public chargers when you need them.

Comstock Metals signs solar recycling agreement with Illuminate USA

Two companies in the solar industry have teamed up to deal with waste from panel manufacturing. Comstock Metals, based in Nevada, will handle transport, sorting, and recycling of manufacturing byproducts from Illuminate USA's solar panel factory in Pataskala, Ohio. That plant, which opened in February 2024, is described as the largest single-site solar panel manufacturing facility in North America. Comstock Metals says its process recovers all the useful material from solar panels and byproducts, breaking them down into raw aluminum, glass, and metal that can be reused, rather than sending waste to landfills. The company recently announced plans to build a recycling and logistics hub in Cambridge, Ohio, about 60 miles from the Illuminate plant. This deal is part of a broader pattern of solar recycling partnerships. Comstock Metals has agreements with RWE Clean Energy for recycling and decommissioning solar installations, and with Virtus Renewables to build out recycling and logistics networks. Separately, Illuminate USA has a deal with another recycler, Solarcycle, to buy recycled glass for use in new panels, with deliveries expected to start in 2028. None of this changes anything for homeowners directly — it's about how manufacturers handle waste and materials at the industrial level. But it points to a growing infrastructure for recycling solar panels and their components in the US, which could matter down the road if you have panels on your roof that eventually need replacing or disposing of.

Sierra Club Condemns Congressional Effort to Attack California’s Waivers Protecting Clean Air

A House Republican has introduced legislation to strip California of its authority to set stronger-than-federal greenhouse gas standards for cars and trucks. Rep. Harriet Hageman's bill uses the Congressional Review Act to revoke a Clean Air Act waiver that lets California enforce its own tougher vehicle emissions rules. This waiver policy is already fully in effect, meaning the cars and trucks it covers are already on the road. The Sierra Club has come out against the move, calling it an attempt by congressional Republicans and the Trump administration to weaken clean air protections and states' rights to regulate vehicle pollution. The group's climate policy director argued that California's waivers have cut pollution, spurred innovation, and saved drivers money, and said repealing them would not lower car costs. For homeowners, this is a policy fight in Washington rather than something that changes any home upgrade or rebate right now. It mainly matters if you live in California or one of the states that follows California's vehicle emissions standards, since those rules affect what cars and trucks are sold and driven there. There's no new deadline, program change, or rebate tied to this news — it's a legislative move that, if it advances, could affect vehicle emissions policy down the road. Nothing here changes home energy programs like weatherization or heat pump incentives.

Keeping solar projects close to home boosts employee morale for Ohio contractor

A Cincinnati solar contractor, TMI Energy Solutions, is choosing to keep its crews working close to home rather than sending them on long-distance jobs. The company used to take on projects in nearby states, including one in New York a couple years back, but has since scaled that back to focus on commercial solar work in the Cincinnati area, like parking garage canopies and rooftop installs up to a few megawatts in size. The change came after leaders noticed crews were burning out from months on the road, even for in-state travel across Ohio. This shift is possible partly because Ohio is seeing a lot more solar development. The advocacy group SEIA ranks Ohio as a top-three state for solar deployments in 2026, which means contractors like TMI have more local projects to choose from instead of needing to chase work elsewhere. For homeowners, this isn't a story about rebates or upgrades you can apply for. It's a sign of how much solar and commercial energy work is picking up in Ohio right now, which can mean more experienced local crews, more competition among installers, and potentially shorter waits for project quotes if you're in the area and considering solar for your own property. It also points to a tight labor market for skilled solar workers, since the company is investing in training and apprentices to keep good workers around for the long haul.

SRP to propose mixed-resource project to its board in September

Salt River Project, the utility serving parts of the Phoenix area, plans to ask its board in September to approve a new power plant about 45 miles south of the city, near Stanfield, Arizona. The Marigold Energy Center would combine 400 megawatts of battery storage, 600 megawatts of solar power, and up to 675 megawatts of gas-fired generation, along with a new substation and transmission lines. The goal is to keep up with growing electricity demand in Maricopa and Pinal counties, where SRP serves customers. If you're an SRP customer in that region, this project is part of how the utility plans to keep power reliable as demand rises, using a mix of solar, batteries, and gas rather than relying on one type of generation. SRP is holding public meetings before the board vote: an in-person session in Stanfield on July 28 and a virtual open house on July 29, following earlier sessions held in December and March. This adds to other storage projects SRP has lined up recently, including a carbon-dioxide-based battery system with Energy Dome announced in June and an iron flow battery pilot with ESS Tech announced last October. None of this changes rebates or programs available to individual homeowners, but it does signal how your local grid is evolving to handle more demand, which can matter if you're considering home upgrades like solar panels, battery storage, or electrification that depend on grid capacity and reliability.

Low-cost catalyst innovation boosts green hydrogen production

Researchers at RMIT University in Australia, working with colleagues in China, have found a cheaper way to boost production of green hydrogen, a fuel made by splitting water using renewable energy rather than fossil fuels. The advance involves a modified version of titanium dioxide, a material already used widely in solar and other energy technologies. The team altered the material by adding nickel atoms, introducing tiny structural defects, and shaping it into hollow spheres that capture light more effectively. In lab tests using a light-driven reaction, the modified material produced more than 80 times more hydrogen than standard, untreated titanium dioxide, and kept performing well after repeated use. Notably, it did this without platinum or other precious metals, which are commonly needed for efficient hydrogen production but drive up costs. This is early-stage research. The tests were done under controlled lab conditions with a chemical solution, not full sunlight or real-world water, so the researchers say more work is needed before this could be used at scale. Still, the findings point toward a path for making green hydrogen cheaper to produce using common, low-cost materials instead of expensive metals. For homeowners, this isn't something you can act on today. Green hydrogen is mainly discussed as a tool for decarbonizing heavy industry, not as a home heating or power option. But cheaper hydrogen production could eventually influence energy costs and the broader shift away from fossil fuels, which shapes the energy landscape your home operates within over the long term.

Tesla (TSLA) Q2 2026 earnings preview: strong deliveries, murky profits

Tesla reports its second-quarter financial results tomorrow, and the numbers so far look strong on the surface. The company delivered 480,126 vehicles, up 25% from a year ago and its best-ever second quarter, while also deploying 13.5 GWh of home and grid battery storage, up more than 40% from last year. Revenue is expected to land around $26 billion, also a solid jump. The open question is whether Tesla actually made money on all those sales, or whether it had to cut prices and offer cheap financing to move that many cars. Analyst estimates for profit per share vary widely, from as low as $0.27 to as high as $0.74, which shows real disagreement about what's under the hood. Adding to the pressure, Tesla's revenue from selling regulatory credits has been shrinking fast, and the $7,500 federal EV tax credit that used to help buyers ended last September. None of this changes what any tax credits or rebates exist for your own home right now, since federal EV incentives are gone regardless of Tesla's results. For homeowners, this earnings report itself has no direct bearing on your house or utility bill. But if you own an EV, charging it from home solar remains one of the more reliable ways to keep fuel costs low and steady, regardless of how any single automaker's quarter turns out.

Why the Iran war hasn’t caused a global oil crisis — yet

When Iran closed the Strait of Hormuz in March, forecasters warned of fuel rationing, mass flight cancellations, and oil at $200 a barrel. That has not happened. Countries released more than 400 million barrels from emergency stockpiles, the U.S. and other producers pumped more crude, and more than 100 countries cut fuel use through measures like shorter work weeks and driving restrictions. Oil prices spiked but eased after a June ceasefire, before climbing again to about $85 a barrel in July when the ceasefire broke down. For U.S. homeowners, the most visible effect so far has been at the gas pump and grocery store rather than at home. Gasoline inventories are unusually low heading into summer driving season, since refiners have been making more jet fuel and less gasoline, and prices for goods tied to Middle East shipping routes, including some materials used in electronics, have risen. There is no mention here of new home energy rebates, appliance costs, or heating and cooling prices tied to this conflict. Analysts warn the relief may not last. Stockpiles that cushioned the first months of the crisis are running low, and China has resumed buying oil for its own refineries. If the strait stays closed, experts say prices may have to rise sharply to bring supply and demand back into balance, since the world no longer has the same buffer of reserves and idle production it used earlier this year.

This is a profile of Drake Decker, owner of Marbledale Plumbing, part of a series honoring people in the building trades. He started as an apprentice at the company after high school, earned his plumbing license through night classes and trade school while working full-time, and eventually took over ownership. The piece isn't about a program, product, or rebate you can use on your own home. It's a personality feature on Decker's approach to the trade: staying current on new products and techniques, walking homeowners through system and product choices so they understand what they're paying for, and mentoring three apprentices along with teaching plumbing basics to kids through a trades outreach program.

Why Logitech puts a carbon footprint label on every product

Logitech, the maker of computer mice, keyboards, and other accessories, now prints a carbon footprint label on its packaging, showing how much greenhouse gas emissions a product created across its life, from raw materials and manufacturing to shipping, packaging, energy use, and disposal. The number is expressed in kilograms of carbon dioxide equivalent (kg CO2e). For example, a Logitech MX Master 3S mouse carries a footprint of 7.78 kg CO2e. This labeling comes out of a broader push the company calls Design for Sustainability, where engineers weigh a product's carbon impact alongside its features during development. That approach has led to changes like adding recycled plastic (now in more than 80 percent of products), using low-carbon aluminum, extending battery life, and making devices easier to repair. One notable switch: replacing plastic clamshell packaging with paper boxes for its retail mice, which cut plastic use and, according to the company, turned out to be something shoppers actually preferred since the plastic packaging was hard to open. None of this requires anything from homeowners, but it does mean that if you buy Logitech accessories, like a mouse, keyboard, headset, or webcam, for a home office setup, you can check the carbon footprint number on the box and compare it to other products or previous versions. Logitech says this labeling is meant to give buyers a clearer, verified way to weigh the environmental cost of what they're purchasing, not just the price or features.

Comstock to recycle scrap material from Illuminate USA’s Ohio solar panel factory

Comstock Metals has signed a deal to recycle leftover material from Illuminate USA's solar panel factory in central Ohio, a plant that assembles panels at a 5-gigawatt scale. Under the agreement, Comstock will handle transport, sorting, and recycling of manufacturing byproducts left over from the panel-making process, aiming for a "zero-landfill" outcome where all scrap gets turned into new industrial materials rather than thrown away. This is a manufacturing-side deal, not a program for panels already installed on homes or in solar arrays. It deals with waste generated while panels are being built, not end-of-life recycling for rooftop solar systems. Comstock has been expanding its recycling network in the region, including a hub it recently set up in central Ohio, and this new agreement with Illuminate is part of that broader buildout. For homeowners, this doesn't change anything about installing solar, applying for rebates, or costs tied to your own system. It's a sign that the solar manufacturing industry is putting more effort into reducing waste and environmental impact at the factory level. If you're choosing panels and care about how sustainably they're made, this kind of supply-chain move is the sort of detail that could matter, but it has no direct bearing on pricing, incentives, or timelines for a home solar or energy-efficiency project.

A Faucet Fit for the Backyard

If you're building an outdoor kitchen, the faucet matters as much as the counters and cabinets. Most indoor kitchen faucets are made from 304 stainless steel, which holds up fine inside but can wear out faster outdoors, where UV rays and swinging temperatures take a toll. Brizo has released a line built specifically for outdoor use: the Odin Outdoor Kitchen Faucets. These faucets use 316 marine-grade stainless steel, a stronger alloy that contains molybdenum, an element that helps resist oxidation, corrosion, and discoloration. That's especially useful if you live near the coast, where salt air speeds up corrosion on outdoor fixtures. The faucets also have quick-disconnect fittings, which make it easier to drain the lines before winter, and flexible PEX tubing designed to add some freeze resistance in case a faucet gets caught by an unexpected cold snap without being drained first. The Odin line comes in seven finish options, with prices starting around $1,300. For anyone planning an outdoor kitchen, it's a reminder that fixtures made for indoor use often aren't built to survive sun, salt air, and freeze-thaw cycles outside, and that outdoor-rated hardware, while pricier, is designed to last longer in those conditions.

Tangle-Free Tie-Downs

This isn't an energy-upgrade story, but it's a small item worth knowing about if you haul materials or equipment for any home project. Titan Straps are tie-downs made of a rubbery plastic that stretches like a bungee cord but locks shut like a belt buckle, so one strap can handle a range of jobs instead of needing separate bungees, ratchet straps, and stretch wrap. The main advantage over a bungee cord is that these straps have no metal hooks, so they won't scratch surfaces or tangle when you pull them out of a bag. They also hold up better than stretch wrap, which can shred, or bungees, which can unravel. Beyond tying down cargo in a truck bed, they can double as a way to bundle cords or clamp glued pieces of wood while they dry. The straps are rated for loads up to 70 pounds and come in lengths from 10 to 36 inches. A four-pack of the larger size runs about $50 through the manufacturer's website. If you're planning any DIY work around an energy retrofit, like hauling insulation, ductwork, or a new water heater, a sturdier, tangle-free strap like this could make transport a little easier, though it has no direct connection to energy savings or rebates.

Sofab Inks announces $6 million in funding to advance novel perovskite ETL materials

A Kentucky-based materials company, Sofab Inks, has raised $6 million to scale up a component used in a next generation of solar panels called perovskite cells. These panels are seen as a potential upgrade over today's standard silicon solar panels, offering higher efficiency, though they are not yet widely available for home installation. The funding will help the company mass-produce a material called Tinfab, which replaces a fragile layer in perovskite solar cells known as C60. That layer has been a weak point: researchers have found it prone to cracking and peeling apart over time, which can shorten a panel's working life. Sofab says its replacement material bonds much more strongly and has shown steady performance after extended lab testing that simulates heat and humidity exposure, along with strong efficiency results on larger test panels. The company says it is working with several partners already building perovskite modules, and plans to triple its engineering team to move from small-scale production to full-size commercial panels. For homeowners, this is not a product you can buy or install now. Perovskite solar technology is still moving from the lab toward commercial manufacturing, and this funding is aimed at solving one of the durability problems that has kept it from being ready for real-world roofs. If the technology matures as planned, it could eventually mean more efficient solar panels, but any home installations remain some way off.
