Policy issues plague hydropower as wind power backup

Theoretically, hydropower can step in when wind turbines go still, but barriers to this non-polluting resource serving as a backup are largely policy- and regulation-based, according to Penn State researchers.

"We have a very clear realization that we need to make energy systems more sustainable," said Seth A. Blumsack, assistant professor of energy policy. "We want to reduce the environmental footprint -- carbon dioxide and conventional pollutants."
