In 2014, after disastrous spills and opposition from environmentalists, the Environmental Protection Agency imposed new rules on the storage of coal ash. Now utilities are planning to close down the ponds that hold the toxic ash, but it has to go somewhere. Environmentalists say the safest place for it is in securely lined landfills, such as the municipal landfill in Wayne County, Ga. Locals are fighting the plan, but there's not much they can do.
Biomass was rising a decade ago as a carbon-neutral energy. But the industry is sputtering as oil and natural gas booms, and some scientists are questioning if it's actually good for the environment.
Scientists who have been tracking cloud patterns over the past two decades say the shifts they're seeing seem to correlate closely with what's predicted by computer models of Earth's changing climate.
The massive toxic algae bloom in Florida is threatening businesses and the health of people and animals. The state is asking for federal help for a disaster that's both natural and political.
The Kemper Project is an electrical generating station currently under construction in Kemper County, Miss. The plant has been held up as a model of the Obama administration's efforts to promote new, clean energy technologies, but the project is two years behind schedule, still not operational, and more than $4 billion over budget. NPR's Ari Shapiro talks to Ian Urbina of The New York Times about the Kemper Project and the administration's clean energy policy.
In 2014, after disastrous spills and opposition from environmentalists, the EPA imposed new rules on the storage of coal ash. Two towns are pushing back against different ways of storing the ash.
A project called TransActive Grid is testing a new way to trade solar power among neighbors. For now only credits are being traded — not actual energy — using the technology that underpins bitcoin.
