A new International Energy Agency report contains some startling findings about solar energy dominance and its future. The study found that renewables comprised 66% of all new net electricity capacity additions in 2016. Two-thirds of added capacity, in other words, consisted of photovoltaic solar cells, wind turbines and biofuels. 165 gigawatts of new solar was added in 2016. In 2016, new solar photovoltaic capacity globally grew by 50 percent.
