Is global warming making it harder to be “green”?

Scientist at the University of Washington are currently studying the effects of global warming on hydro powered dams. These scientist are finding that a warming of around two degrees would result in a twenty five percent decrease in hydro dams electricity yield. The problem is that as temperature increases water levels will peak earlier causing summer water levels to be significantly lower. This decrease in water makes this “green” technology less efficient. Unfortunately this decrease in water would also cause problems for the salmon. Scientist are working on a system that would supplement the rivers with stored water through the dry months. I feel this report will make hydro power a lot less popular to companies.
