New wind resource maps and wind potential tables for the lower 48 states were recently released by AWS Truewind in collaboration with the National Renewable Energy Laboratory (NREL). This new data marks the first state-by-state comprehensive update of wind energy potential since 1993. Accurate information about the wind resources available in each state will help keep the momentum in wind energy development going strong in 2010. If state and federal policies need valid evidence of wind potential to promote this clean energy source, then that data has arrived.
