The newest estimates of U.S. technical potential for renewable energy generation and capacity were reported recently by scientists at the National Renewable Energy Laboratory (NREL), the U.S. Department of Energy research facility.

For the six technologies evaluated, total technical annual generation potential was estimated at 481,800 terawatt-hours and total technical cumulative capacity potential at 212,224 gigawatts. In 2010, aggregate generation sales for all 50 states, according to the report, amounted to roughly 3,754 terawatt-hours.
