Scientists have come up with a way to make wind farms more energy efficient, and it doesn’t require new investment. Wind turbines are controlled as freestanding units and only maximize their own power production, but the wake of each wind turbine impacts each other. MIT’s Esther and Harold E. Edgerton assistant professor of…

Clean energy accounted for more than two-thirds of the new US electrical generating capacity added during the first six months of 2022, according to data recently released by the Federal Energy Regulatory Commission (FERC). Wind (5,722 megawatts) and solar (3,895 MW) provided 67.01% of the 14,352 MW in utility-scale (that is, greater than 1…

US President Joe Biden today signed the Inflation Reduction Act into law, and that’s going to give the transition of the United States to clean energy a big boost. According to the American Clean Power Association, the new law could add up to an additional 550 gigawatts (GW) of electricity from wind, solar, and other…

Electric utility FirstEnergy Corp., which serves most of northern West Virginia, is going to repurpose a former coal ash landfill for a utility-scale solar farm. The Natural Resources Defense Council explains what coal ash is, and notes that it’s the US’s second-largest waste stream behind household trash: Coal ash is a general term –…

US President Joe Biden signed the big climate bill – the Inflation Reduction Act (IRA) – earlier this week. Electrek spoke with Dan Gayer, JD, CPA, a senior manager in the tax practice at Baker Newman Noyes, about how homeowners can claim tax credits and rebates as they work to achieve energy efficiency and lower…

Denver-based Guzman Energy almost didn’t get approval for a solar farm it’s going to build in western Colorado, but when the wholesale power provider agreed to add irrigation to support 1,000 sheep and possibly host beehives, it then gained unanimous approval from Delta County, Colorado’s commissioners. When Guzman Energy’s 80-megawatt (MW) Garnet Mesa Solar…

Seagreen offshore wind farm, 16.7 miles (27 km) off the coast of Angus in eastern Scotland, has generated its first power. The £3 billion ($3.54 billion) project will be Scotland’s largest offshore wind farm. It will also be the world’s deepest fixed-bottom offshore wind farm, as it’s being sited in water depths of up to…

The Tennessee Valley Authority (TVA) – the largest utility in the United States – will launch a first-of-its-kind pilot program to determine whether closed coal ash storage sites can host utility-scale solar. Solar on coal ash sites Pending environmental reviews and regulatory approval, the $216 million pilot project would explore repurposing a capped 300-acre…

In research that could jumpstart work on a range of technologies including fuel cells – key to storing solar and wind energy – MIT researchers have found a relatively simple way to increase the lifetimes of these devices: changing the “pH” of the system. The US Department of Energy explains how fuel cells work:…

Renewables provided more than 25% of electrical generation in the United States during the first half of 2022, according to new data from the US Energy Information Administration (EIA). The latest issue of the EIA’s “Electric Power Monthly” report released yesterday, which contains data through June 30, 2022, shows that in the first half…
