Google is backing the buildout of a novel green-steel mill in Sweden as the tech giant grapples with rising greenhouse gas emissions from its AI expansion. On Thursday, the company said it is partnering with Stegra to help bring the Swedish firm’s flagship facility online. Unlike traditional coal-fueled mills,…

Making the cement that holds together our buildings and streets is a highly carbon-intensive process — one that involves burning lots of fossil fuels to blast materials with searing heat. But startups are developing technologies that could use clean electricity to produce cement instead, and a Boston-based firm is…

A third shuttered U.S. nuclear power plant is set to attempt a comeback with hefty support from the federal government. On Tuesday, the U.S. Department of Energy said it closed a loan of up to $1.9 billion to NextEra Energy to help finance the restart of the Duane Arnold Energy Center in Iowa, which shut down six…

Hyundai is set to break ground in southern Louisiana this week on a nearly $6 billion steel mill , which may become the lowest-carbon facility of its kind in the U.S. On Friday, the Korean industrial giant will hold a ceremony at the project site, where the fields of a former sugarcane plantation have been cleared…

Fervo Energy inked a landmark deal to supply Google with nearly 400 megawatts of clean electricity from the startup’s geothermal project in southwest Utah. The agreement is the largest of its kind for a next-generation geothermal system — an emerging technology that involves drilling deep into hot, dry rock to use…

The Trump administration has agreed to fork over nearly $4 billion since the spring to get major energy firms to abandon a dozen leases for U.S. offshore wind projects. The controversial maneuver to return lease payments to developers — often in exchange for their investing in fossil fuels — is part of President…

Thousands of feet beneath the desert valley of southwest Utah, a slender tool tucked inside a drill pipe is barreling through hot granite. The rod-shaped device, built by the startup Hephae Energy Technology , is a tracker of sorts, wirelessly sending data to help operators above steer the drill below and to measure…

A $500 million Biden-era grant to decarbonize steelmaking has been refashioned by the Trump administration to upgrade a coal-fueled blast furnace in southern Ohio. On Friday, Cleveland-Cliffs confirmed that the U.S. Department of Energy had changed the scope of the previously awarded funding for Cliffs’ Middletown…

Sage Geosystems has hit a big milestone out on a rugged tract near San Antonio: The startup is producing power from its first next-generation geothermal plant. The system is just the third of its kind to come online in the U.S. as the sector races to commercialize the source of on-demand clean electricity. The novel…

Next-generation geothermal energy has massive potential in the western United States, but it won’t be realized unless developers can overcome the big economic barriers these novel systems face. Unlike traditional geothermal plants, next-gen projects use innovative underground techniques to produce power wherever…

America’s aluminum sector is growing again after years of decline, spurred by tariffs and a push to revive domestic manufacturing. But the voracious power needs of aluminum smelters and communities’ concerns about pollution still pose major hurdles to scaling up production. Globally, a deficit in aluminum supply is…

The Department of Energy is backing a major battery project to bolster Puerto Rico’s fragile electric grid — even as the Trump administration axes funding for key clean energy initiatives across the U.S. territory. Last week, the DOE said it closed a nearly $490 million loan to a subsidiary of Pattern Energy to…

The startup Antora Energy just raised $550 million to build and deploy more of its heat-storing batteries for powering data centers and cleaning up factories. On Thursday, San Jose, California–based Antora said it closed a Series C funding round co-led by climatetech investor G2 Venture Partners and the VC firm…

Construction is underway on a $1.7 billion solar and battery storage project in Texas that will turn existing coal mining land into a hub of clean energy generation. Panamint Capital announced last week that it broke ground on the 1.2-gigawatt Big Rooter Power solar farm in Bremond, about halfway between Dallas and…

American households are all too familiar with the pain of high electric bills, which are climbing nationwide. The same problem is quietly hindering the country’s factories from cleaning up their operations, too. Hundreds of thousands of U.S. manufacturing facilities burn fossil fuels to produce the heat they need to…

Over two decades ago, Ormat Technologies began a big experiment on a swath of rugged land near the Hot Springs Mountains in western Nevada. The geothermal company was already producing electricity there, using the heat found naturally in hot water and steam trapped beneath the earth’s surface. But in 2002, Ormat and…

America’s offshore wind farms have already shown their ability to keep electricity flowing during brutal winter storms. Now, the clean energy resource has proved it can also bolster the grid during major heat waves. Earlier this month, as dangerously hot and humid temperatures settled over the eastern United States,…

Earlier this month, as a historic heat dome smothered the U.S. Midwest and Atlantic Coast, New York City Mayor Zohran Mamdani asked residents to set their air conditioners to 78 degrees Fahrenheit to protect the city’s severely strained grid. “Let's ease demand — and get through the heat — together,” he posted on X…

Southern California’s landmark rule to slash emissions from industrial heating sources just notched a major victory in court. The region has some of the worst air quality in the U.S., and the gas-fueled boilers and water heaters that serve its factories and large buildings are a key culprit. In 2024, air quality…

Startup Quaise Energy has raised $134 million to advance its first superhot geothermal power plant in central Oregon. On Tuesday, the Houston-based company announced the first tranche of its Series B financing round, which brings the firm’s total funding to $230 million. Quaise is developing a 50-megawatt plant near…
