The world's renewable power capacity—the amount of energy that can be produced from sources comprising hydropower, wind, solar, bio-energy, and geothermal—has doubled in the last decade. From 2008 to 2017, it went from 1,060 gigawatts to 2,179 gigawatts, according to research from the International Renewable Energy Agency (IRENA), an intergovernmental organization.

Over that period, world renewable energy production has also increased, from over 3.7 million gigawatt hours to almost 5.9 million gigawatt hours.
