If Germany can do it, the US can too. Renewable energy is now 20% of the power mix there.
Germany produced more energy from renewable sources than from nuclear, hard-coal or gas-fired plants this year after boosting investments in projects from wind to biomass.
Renewables accounted for a fifth of the generation mix in 2011, up from 16.4 percent last year… Only lignite- fired output, with 24.6 percent, had a greater share
Lignite, which is mined in Germany and elsewhere, is a fuel somewhere between coal and peat.
