The renewable energy could ease global warming, but the dams and turbines could result in mass killings..

Reporting from Wenatchee, Wash. -- The Rocky Reach Dam has straddled the wide, slow Columbia River since the 1950s. It generates enough electricity to supply homes and industries across Washington and Oregon.
But the dam in recent years hasn't produced as much power as it might: Its massive turbines act as deadly blender blades to young salmon, and engineers often have had to let the river flow over the spillway to halt the slaughter, wasting the water's energy potential.
The ability of the nation's aging hydroelectric dams to produce energy free of the curse of greenhouse gas emissions and Middle Eastern politics has suddenly made them financially attractive -- thanks to the new economics of climate change. Armed with the possibility of powerful new cap-and-trade financial bonuses, the National Hydropower Assn. has set a goal of doubling the nation's hydropower capacity by 2025. . . ."

We can have all the electricity we need without emissions and without hurting wildlife. For more information, please see www.terrahumanafoundation.org.
