A report from the Renewable Energy Policy Network for the 21st Century (REN21) noted that renewable sources supplied 20 percent of the world's final energy consumption by the end of 2010 and one-quarter of global power capacity from all sources by early 2011. The “Renewables 2011 Global Status Report” said Global capacity of renewable energy technologies—photovoltaic cells, wind power, solar energy, and biofuels—grew at average rates of 15 to 50 percent annually. In addition, the report noted that renewable energy accounted for approximately half of the estimated 194 GW of new electric capacity added globally in 2010. The number of countries with policies that support renewable energy generation increased to 119 by early 2011, up from 55 in 2005. In the United States, renewable energy accounted for 10.9 percent of domestic primary energy production in 2010, the report said. According to the U.S. Energy Information Administration, renewable energy made up 8 percent of total consumption that year. By comparison, energy from nuclear power made up 11.3 percent of U.S. energy production, the report said. In China, the report noted that renewable energy sources accounted for about 26 percent of the country's total installed electric capacity.
