A recent Renewable Energy Policy Network for the 21st Century report claims that by early 2011, renewable sources accounted for 25 percent of global power capacity from all sources. The network is described as a global partnership that connects governments, international organizations and industry on renewable energy matters.

According to the report, global capacity of renewable energy technologies— photovoltaic cells, wind power, solar energy, and biofuels—grew at average rates of 15 to 50 percent annually from 2005 through 2010. During the same period, countries with policies that support renewable energy generation increased from 55 to 118. Renewable energy reportedly accounted for 10.9 percent of domestic primary energy production in the United States in 2010, 26 percent in China, 22 percent in Denmark, and 11 percent in Germany. The report notes that the recent increase in worldwide renewable energy occurred despite a global recession.
