Solar only works when the sun is shining, and wind only works when the wind is blowing so, as Donald Trump has reasoned in the past (http://bit.ly/d-trump-reasoned), they couldn’t possibly handle all of our energy demand, right? WRONG! In a recently published paper by Dr. Ken Caldeira in the journal, Energy and Environmental Science (http://bit.ly/jo-nrg-enviro-science), 36 years of hourly weather data was analyzed showing that these two energy sources fluctuate in complementary ways. The study shows a clear path to 100% renewable energy, with just solar and wind! Fortunately, we have other renewable energy sources which can help including advanced wood heating, hydroelectricity, and geothermal energy – not to mention all of the work we have yet to do to use energy more efficiently.
