Renewable Energy Patents Booming, Led by Solar and Wind

Time series for US energy patents published during the period 1974-2009 show rapid growth over the last decade, with the greatest increases in renewables patents. (Credit: MIT) Click to enlarge.
Patents for renewable energy technologies, led by innovations related to solar and wind, have risen drastically over the last decade, according to a new study from researchers at MIT and the Santa Fe Institute.  The research shows that while patents in fossil fuel technologies grew modestly, and nuclear technology remained flat, between 2004 and 2009 the number of patents issued annually for solar energy increased by 13 percent per year, while those for wind energy increased 19 percent per year on average.

 The study attributes investment in R&D and market demand for helping spur such growth, which for solar and wind exceeded patent growth rates for semiconductor and digital communications technologies.
