In 2015, renewable energy investments hit $286 billion, a five percent increase from 2014. Global investments in renewable energy were double that spent on new coal and natural gas-fired power generation. Thanks to greater spending, a total of 147 gigawatts (GW) of renewable energy capacity was added in 2015. China was the biggest spender, accounting for a third of all renewable energy spending, but India, South Africa, Mexico and Chile all had major increases in green energy investments.
