A new report by Navigant Research projects that distributed generation will roughly double in the next nine years.  

Think Progress : “Distributed generation (DG) is the decentralized production of electricity by small-scale systems — most often in the form of rooftop solar, but it can include biomass, wind, and other forms of renewable power as well. Navigant Research’s analysis also included natural gas and diesel generators of 6 megawatts or less, along with solar arrays of one megawatt or less and small wind turbines of 500 kilowatts or less.”  

“According to their forecast (unfortunately behind a paywall) the total capacity for DG installed around the world will grow from 87.3 gigawatts in 2014 to 165.5 gigawatts in 2023. Most of the growth is anticipated to come from the deployment of solar. Geographically, the biggest increase in the projection was in Western Europe, with North America and the Asian Pacific not too far behind.”
