Seasonal celebrations cause spikes in certain food waste, which can either rot in landfill or be fed as a slurry to the microorganisms responsible for producing biogas through anaerobic digestion (AD). However, microbes are picky, and efficient AD requires a balanced diet. This presents a challenge to the producers of biogas and biomethane, who prepare...
When Army Maj. Eric Czaja thinks about America’s military readiness, he doesn’t just think about soldiers, weapons or strategy. He thinks about soil. “We are grazing for national security,” Czaja says. “We are creating installations that can withstand the punishment we dish out in our training. We can do that with livestock as a tool.” ...
The sky turns a rusty orange. The sun dims behind a thick veil of smoke. For millions of Americans, even ones far from wildfire-prone lands, this eerie scene is no longer rare. Extreme wildfires have doubled in frequency and intensity in recent decades, and their smoke is erasing decades of gains in clean air. Fine particulate matter from...
The Department of Energy has announced a new $100 million funding opportunity to refurbish and modernize the nation’s coal-fired power plants. The initiative, outlined in a newly issued Notice of Funding Opportunity, or NOFO, aims to extend plant lifetimes, boost efficiency, and strengthen the reliability of the U.S. power grid. The funding follows DOE’s September plan to invest $625...
Health and Human Services Secretary Robert F. Kennedy Jr. directed Centers for Disease Control and Prevention staff to probe the potential harms of offshore wind farms, according to people familiar with the matter, as President Donald Trump marshals his administration to thwart the clean energy source he loathes. In late summer, HHS instructed CDC’s National Institute for...
The Senate on Thursday voted to overturn a Biden administration plan that would have restricted drilling in the Arctic. The vote was 52-45. Sen. John Fetterman (D-Pa.) joined Republicans in voting in favor. The 2022 Biden administration plan in question made about 52 percent of land available for drilling in an area known as the National Petroleum Reserve in Alaska. A...
Over a dozen Republican House members, in a letter to Agriculture Secretary Brooke Rollins and Trade Representative Jamieson Greer, expressed concern over the Trump administration’s plan to boost imports of Argentine beef. “We encourage the Administration to ensure that any adjustments to Argentina’s tariff-rate quota or inspection regime be contingent on verified equivalency and reciprocal market access for...
President Trump said he and Chinese President Xi Jinping agreed on a wide range of subjects during their much-anticipated meeting Thursday, including the key issues of tariffs and access to rare earth materials. It was their first face-to-face meeting in six years, going back to Trump’s first term. Their relationship has been rocky at times as they’ve been...
Resilient Power in the Deep Freeze Researchers have achieved a significant breakthrough in energy storage for cold climates. Newly tested sodium-ion batteries can function effectively at temperatures where conventional lithium-ion systems lose most of their capacity. In trials published by Communications Chemistry in September 2025, sodium-ion pouch cells maintained 74 Wh/kg at −25 °C (−13 °F) and...
Maine and Connecticut are considering working together to build renewable-energy projects faster, a strategy that could be repeated throughout the region as states with ambitious emissions-reduction goals race to take advantage of federal tax credits before they disappear. “They’re trying to collaborate, trying to coordinate,” said Francis Pullaro, president of clean-energy trade association Renew Northeast. “This is...
