The Clean Energy Patent Growth Index (CEPGI) has released its 2013 Year in Review report. The report, tracking green patent trends by sector, provides some interesting insight on the status of Energy Technology investing.

Though there had been talk of an Energy Technology investing slowdown in 2013, the CEPGI report indicates that the number of green patentees is rapidly growing, especially in the solar sector. U.S. patents for Clean Energy technologies hit an all-time high in 2013, and nearly 1500 entities contributed to Clean Energy patents. Solar rose as the leading sector in number of patents, taking Fuel Cell patents from the top spot for the first time since 2002.

These statistics imply that Energy Technology remains extremely dynamic, and market adoption of Energy Technology products is continually increasing. As innovation in these sectors continues, it is very likely that Energy Technology will have a long and profitable future.
