“What we are witnessing is the birth of a new era in solar PV…We expect that solar PV capacity growth will be higher than any other renewable technology through 2022. We see renewables growing by about 1,000 gigawatts by 2022, which equals about half of the current global capacity in coal power, which took 80 years to build.”

 —  International Energy Agency executive director Fatih Birol commenting on solar’s rapid global growth over the past year. New solar photovoltaic (PV) capacity increased by 50% in 2016, faster than any other energy source.
