Wendy Koch, USA TODAY October 12, 2013. Just how much better can a solar panel or wind turbine be? Quite a bit, suggests the surging number of global patents for renewable technologies. (Photo: AP) Innovators seek more patents for the booming solar and wind markets, and an MIT study finds there are now more of these patents than for fossil fuels. Rising global demand for renewable energy is driving innovation. Innovation in solar, wind and other renewable power is booming worldwide, especially in China, and is now eclipsing that in fossil fuels — an about-face that occurred in just one generation, new research shows. In the United States alone, the number of renewable-energy patents exceeded 1,000 annually by 2009 — up from fewer than 200 per year in the 1975-2000 period. In contrast, patents for coal, oil or gas technologies rose to about 300 in 2009, up from 100 annually in earlier decades
