Clean energy overtakes fossil fuels
The electricity system has been shifting to clean and this trend is here to stay. According to a 2015 analysis from Bloomberg New Energy Finance, the world is now adding more capacity for renewable power each year than coal, natural gas, and oil combined. The shift occurred in 2013, when the world added 143 gigawatts of renewable electricity capacity, compared with 141 gigawatts in new plants that burn fossil fuels.
This trend is even more surprising when considering the 2000 IEA world energy outlook at the beginning of the millennium that forecasted the share of renewables would climb to only 3% by 2020 and from then 2%. The 2015 IEA world energy outlook already revised the share of renewable energy in global power generation to over 26% by 2020 from 22% in 2013 – a remarkable shift in a very limited period of time.
