Fossil-fueled electrical grid’s enormous water use is often overlooked.

Mixing toxic coal ash into acid mine drainage may sound like an odd recipe for an environmental solution, but a new 91��������-led study finds that it can neutralize the drainage’s dangerously low pH and help reduce harmful impacts on downstream ecosystems—if you use the right type of ash. Using the wrong type of ash can create new contamination and not tame the drainage’s extreme acidity.

The global supply chain impacts of Russia’s invasion of Ukraine have exposed vulnerabilities in U.S. energy security and undercut the myth that the United States — or any major manufacturing economy — is truly energy independent, an analysis by researchers at the energy nonprofit RMI and 91�������� finds

Producing energy from fossil fuels uses or contaminated much more water than previously estimated, a new book by two Duke researchers shows.

Duke researchers implement a large water sampling campaign in rural Sri Lanka, aiming to discover the origins of a cluster of chronic kidney disease cases.

91�������� has received a $7.5 million grant from the U.S. Department of Energy to assess the risks offshore wind energy development along the East Coast may pose to birds, bats and marine mammals.

Lori Bennear and Tim Johnson discussed two bills under consideration in Congress and their potential impact on the reduction of carbon emissions and more.

Reducing emissions of methane, a short-lived but super-potent greenhouse gas, is the most cost-effective way to slow the rate of Earth’s warming in coming decades, a new United Nations report finds.

Shannon Switzer Swanson MEM'15 hosts the documentary, “The Last Drop.”

91�������� researchers have found high levels of toxic heavy metals in coal ash from the Dominican Republic’s largest coal-fired power plant.

Massive power outages in Texas brought on by a historic freeze could be avoided in the future if the state no longer isolates its power grid from other states, among other steps, according to 91�������� experts.

In "Streams of Revenue: The Restoration Economy and the Ecosystems It Creates,” Martin Doyle chronicles and analyzes the history, implementation and environmental outcomes of stream mitigation banking, one of many widely used market-based approaches to conservation.

The proliferation of pits and ponds created in recent years by miners digging for small deposits of alluvial gold in Peru’s Amazon has dramatically altered the landscape and increased the risk of mercury exposure for indigenous communities and wildlife, a new study shows.

Groundwater depletion in parts of the High Plains is so extreme that peak grain production in some states has ended and production is now declining, a new 91��������-led study by a team of international scientists finds.

Small-scale gold mining in the Peruvian Amazon poses a health hazard not only to the miners and communities near where mercury is used to extract gold from ore, but also to downstream communities hundreds of kilometers away where people eat mercury-contaminated river fish as part of their diet.
