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
