As recently as 2012, South Africa had very little wind energy capacity—10 MW to be precise—and it had taken ten years to get to that point. Now, in 2016, it is right around 2 GW. That’s something like a 1900% increase in four years. And according to consulting firm GlobalData, another 3 GW are due to be added in the next four years. South Africa meets a full 77% of its energy needs directly from coal, and the South African energy sector emits 250 million tons (MT) of carbon dioxide equivalent annually.
