As of 2009 hydro only supplied about 6.9% of the US electrical generating capacity (and that percentage is dropping). All other renewables (Wind, Solar, Geothermal, etc..) composed about 3.6% . Nuclear power supplies about 20% of US needs. When you consider there are no more rivers that can be dammed, people oppose nuke, the fact that wind and solar aren't consistent and cost a lot, and by 2027 we will only have a fusion reactor that will run for 1000 seconds at a time, there isn't anyway we are going to ween ourselves from fossil fuel energy production anytime soon .
