The 103GW of capacity added by renewables last year (2014) equals the energy generating capacity of all 158 nuclear power plant reactors in the USA.
…Wind, solar, biomass and waste-to-power, geothermal, small hydro and marine power contributed an estimated 9.1% of world electricity generation in 2014, up from 8.5% in 2013. This meant that last year the world electricity system emitted 1.3 gigatonnes of CO2 – roughly twice the emissions of the world’s airline industry – less than it would have if that 9.1% had been produced by the same fossil-dominated mix generating the other 90.9% of world power.
“Once again in 2014, renewables made up nearly half of the net power capacity added worldwide” says Achim Steiner, UN Under-Secretary-General and Executive Director of UNEP.
