In the span of a few short years, the solar-energy business has elbowed its way from the fringe of the global energy game to become its fastest-growing segment, according to a report published by the Paris-based Renewable Energy Policy Network (REN21).
Installed grid-connected solar photovoltaic (PV) capacity grew by 5.4 gigawatts (GW) -- a rate of 70% -- to reach a total of 13 gigawatts (GW).
