Using data from EIA.gov, the annual additions to US electricity generation from combined wind and solar have now effectively halted net fossil fuel growth, in US electricity generation. As solar costs continue to tumble, and now that distributed generation (small rooftop solar) is now coming on strong, there is little prospect that natural gas or coal will ever again make net gains, in US power generation. As you can see from the chart, power generation from sources ex-wind+solar have been in decline since 2007, and have flatlined the past three years--it appears they will flatline again in 2015. Moreover, all the net growth now in US power generation comes from combined wind-solar. Amazingly, combined wind and solar crossed the 5% share threshold last year.
