Use of renewable energy continued to grow in 2013. In 2013, biomass represented around 10% of global primary energy supply. In the power-generation market, bio-power added 5 GW of capacity last year, bringing the total to 88 GW, and solar-photovoltaic capacity increased by 39 GW to 139 GW. Capacity also increased for the other categories of renewable-power generation: geothermal power, hydropower, ocean power, concentrating solar thermal power and wind power. In the transport-fuels market, consumption rose 7.7% last year to 116.6 billion L. Ethanol production added 4.6 billion L to bring capacity to 87 billion L, biodiesel product added 2.7 billion L to total 26 billion L, and the production of hydrotreated vegetable oil grew 0.4 billion L to 3 billion L. Renewable energy accounted for 19% of global final energy consumption in 2012. Of this percentage, modern renewable (biomass/geothermal/solar heat, hydropower, wind/solar/biomass/geothermal power, biofuels) and traditional biomass represented 10% and 9%, respectively.
