Is that true across the nation? I know California isn't the whole energy market but their renewable energy mix is solar, hydro, fission, wind, geothermal, and biomass in that order. It's true that non-hydro, non-solar sources are larger than hydro+solar, but not by a lot and none of the renewable supplies are carbon-intensive.

Wind, by the way, is growing much faster than solar in California and could be larger than solar within a few years.
