NREL’s new Wind Resource Database provides public access to more than a petabyte of detailed wind resource data covering the United States and several other countries. That volume of data is the same as about 250 million MP3 songs—to which you could listen nonstop for thousands of years without hearing the same song twice. WTK-LED provides users with a range of possible wind speeds made available at five-minute, 2-kilometer (km) resolution for various regions across the globe.
