Fish-Safe Turbines Empower Small-Dam Hydro Projects
The potential for hydroelectric power from small dams—15 feet or higher—is vast. A 2012 U.S. Department of Energy study, An Assessment of Energy Potential at Non-Powered Dams in the United States, identified 54,000 non-powered dams that could provide 13 gigawatts of capacity. That is enough to power 5 million homes.
