A breakthrough may make the mega flow battery commercially viable in the near future

Wind and solar power have the potential to reduce the growth of greenhouse gases and slow the progression of climate change. But since the sun doesn’t always shine and the wind doesn’t always blow, the big hurdle in expanding the use of renewables is the lack of cheap and efficient storage of that energy. That could be about to change.

Almost Out of Time

Back in the 1970s, NASA scientist James Hansen was one of the first to recognize the dangerous impacts that rising levels of greenhouse gas emissions could have on the earth’s climate. Now this climate scientist has become an activist in the climate movement, lending his scientific voice to calls for urgent action. On the eve of the UN’s Paris climate summit, he tells host Steve Curwood that emissions reductions need to be much steeper than those being discussed. (published November 27, 2015)

A way to save one of North America's fastest animals

For centuries, herds of pronghorn have traveled hundreds of miles across the west in the second longest land migration in North America. But today, pronghorn often encounter barbed wire fences on private and public land that delay or halt their journey. Now, scientists and wildlife managers are developing fencing systems that allow the pronghorn to cross safely.

Nuclear reactor closings in the US continue to roil the energy industry

The Entergy Corporation recently announced it would soon close two aging nuclear power plants in the northeast US. At the same time, the Nuclear Regulatory Commission has granted the company a new license to operate a Tennessee reactor that some experts consider one of the least safe in the nation. What does this portend for nuclear energy in the US?
