Climate in Numbers: Wind and solar power expand fast

It is positive news: Wind and solar energy have expanded rapidly in many countries over the past few years. Today, 12.1 percent of the world’s electricity is generated by wind and solar power plants. In 2015, the share was still at 4.6 percent, as a report by the think tank Ember shows. And the growth continues: Over the weekend, the G7 countries decided to add another 150 gigawatts of offshore wind capacity and 1,000 gigawatts from photovoltaics by 2030.
