Solar power

Fort Polk, a US Army installation in Louisiana, is about to get a big solar power boost. Clean energy developer Onyx Renewables has wrapped up construction on two 13 megawatt ground-mount solar projects. The solar arrays are scheduled to come online this fall.

The storm hit. The power’s out. With all the damage around you, it looks like you might be without power for a few days (at least). But you planned for this. You have a home backup battery. What happens now?

Solar and wind accounted for almost 91% of new US electrical generating capacity added in the first five months of 2025, according to data released on August 20* by the Federal Energy Regulatory Commission (FERC).

Ridgefield, Connecticut, just commissioned a sizable new solar carport at Ridgefield High School, and it’s set to pay big dividends for the town of around 7,000 residents.

This week, industrial real estate giant Prologis flipped the switch on a rooftop solar project at one of its Franklin Park, Illinois warehouses — the first of 45 such rooftop installations the company plans to deploy in the next two years. Once finished, Prologis’ community solar project will generate up to 82 MW of clean energy!

One of the US’s largest solar + battery storage projects is now fully online in Mojave, California. Arevon Energy’s Eland Solar-plus-Storage Project combines 758 megawatts (MWdc) of solar with 300 MW/1,200 megawatt hours of battery storage.

Georgia BRIGHT, a statewide initiative to deliver affordable solar, kicked off its “No-Cost Solar Plan” in Atlanta yesterday, giving qualified homeowners a shot at roughly 400 fully prepaid rooftop-solar systems with zero upfront or maintenance costs. However, Georgia Bright’s No-Cost Solar Plan may lose its $156 million in grant money if the EPA steals back the Solar for All program’s entire $7 billion, which funded it.

Solar panel recycler SOLARCYCLE and Arizona State University just proved that solar panels made with recycled glass work just as well as new ones.

Two years after world leaders pledged to triple global renewable energy capacity by 2030, a new report shows that most countries still aren’t planning like they mean it.

SolarEdge and Solar Landscape are going to turn hundreds of empty commercial rooftops into solar energy generators in the US.

Solar provided over 11% of total US electrical generation in May, while wind + solar produced over one-fifth, and the mix of all renewable energy sources generated nearly 30%, according to data just released by the US Energy Information Administration (EIA).

Nexamp just pulled off something that could speed up clean energy deployment across the US – and potentially lower costs for everyone. The Boston-based solar developer just finished building three new solar farms in Maine and Massachusetts. But instead of waiting on the utility to handle all the grid hookup work, Nexamp did it themselves.

Renewables continued to dominate fossil fuels on price in 2024, according to a new report from the International Renewable Energy Agency (IRENA). The big takeaway: Clean energy is the cheapest power around – by a wide margin. So it’s pretty bad business that the biggest grid upgrade project in US history just got kneecapped by Trump’s Department of Energy to stop the “green scam.”

Enbridge is going big on solar again in Texas, and Meta is snapping up all the solar power it can get.

Sunrun is putting tens of thousands of home batteries to work in Puerto Rico as the island’s electric grid faces a summer of high temperatures and energy shortfalls.

Materials science giant Corning is betting on US solar, buying Chinese-owned JA Solar’s 2 GW factory in Arizona as clean energy tax credit rules tighten.

Flooring manufacturer Beauflor USA just turned on the biggest rooftop solar system by capacity in metro Atlanta — and it’s now powering part of its Georgia factory.

The California Senate dropped a controversial provision of an upcoming solar law which would have broken long-standing solar contracts with California homeowners after significant public backlash over the state’s plans to do so.

Arizona-based First Solar has signed an agreement with quantum dot nanotechnology developer UbiQD (“ubiquity”) to bring quantum dots (QD) into its thin film bifacial solar panels. The multi-year deal could be a big leap forward for boosting solar efficiency.

Solar and wind accounted for almost 96% of new US electrical generating capacity added in the first third of 2025. In April, solar provided 87% of new capacity, making it the 20th consecutive month solar has taken the lead, according to data belatedly posted on July 1 by the Federal Energy Regulatory Commission (FERC) and reviewed by the SUN DAY Campaign.

One of Arizona’s biggest grid battery storage projects is now online and helping power homes as the summer heat ramps up.
