Wind resource potential energy is given in gigawatts (GW) and wave&tidal resource potential energy is given in terawatt-hours/year(TWH/yr). The Electric Power Research Institute (EPRI) estimates the wave energy resource along the outer continental shelf is 2,640 TWh/yr. EPRI also estimates that the recoverable resource along the U.S. shelf edge is 1,170 TWh/yr².
The recoverable wave energy resource for each region is estimated as²:
- West Coast 250 TWh/year
- East Coast 160 TWh/year
- Gulf of Mexico 60 TWh/year
- Alaska 620 TWh/year
- Hawaii 80 TWh/year
- Puerto Rico 20 TWh/year
