wind farmThe smallest U.S. state now faces a big question on energy policy. Rhode Island is in the midst of deciding whether to continue getting a large portion of energy from fossil fuels, or to switch to renewable energy. Those options are represented by two competing projects: a large natural-gas power plant, and an offshore wind farm. DON'T MISS: Dirty...

Carbon-dioxide (CO2) emissions from electricity generation during the first six months of 2016 were the lowest since 1991, according to the U.S. Energy Information Administration (EIA)...

Hydro-power reservoirs emit methane, a greenhouse gas: no free lunch?

Hoover Dam by Flickr user Airwolfhound (Used under CC License)The energy sources used to generate grid electricity can be a major source of greenhouse-gas emissions, and thus they affect the environmental impact of electric cars. The cleaner the electricity used to charge an electric car, the cleaner that car becomes in operation. And among potential energy sources, hydroelectric power from dams would seem...
