Solar power grew faster than any other source of fuel for the first time in 2016, the International Energy Agency said in a report suggesting the technology will dominate renewables in the years ahead.

The institution established after the first major oil crisis in 1973 said 165 gigawatts of renewables were completed last year, which was two-thirds of the net expansion in electricity supply. Solar powered by photovoltaics, or PVs, grew by 50 per cent, with almost half of new plants built in China.

"What we are witnessing is the birth of a new era in solar PV," Fatih Birol, executive director of the IEA, said in a statement accompanying the report published on Wednesday in Paris. "We expect that solar PV capacity growth will be higher than any other renewable technology through 2022."
