Background-Nation WideClimate change calls for renewable energyIn 2009, U.S. hydrokinetic Power ≤ 1 MKW, hydropower > 77,000 MKWAs of 2009, the FERC issued 146 applications to study 9,000 MKWPrediction: Hydrokinetic Energy could provide 13,000 MKW to the U.S. by 2025
EIA Annual Energy Outlook 2010
Quadrillion Btu

Background-State wideResources
Many big rivers90 % of U.S. tidal50% of U.S. wave
Energy PolicySB 220: 18 million increase to 250 million.HB 306: 50% renewable electricity by 2025.
Uneven Electricity Cost Across StateHigh energy cost for rural regions, most of
which are near rivers
