Global Renewable Energy Targets
100% by 2050.
As at July 2010, 30 US states and DC have established mandatory renewable energy targets, and a further 6 have voluntary targets. The Energy Independence and Security Act of 2007 has set a target for 36 billion US gallons (140,000,000 m3) of biofuel produced annually by 2022. Of that, 21 billion US gallons (79,000,000 m3) shall be advanced biofuels (derived from feedstock other than corn starch). Of the 21 billion US gallons (79,000,000 m3), 16 billion shall come from cellulosic ethanol. The remaining 5 billion US gallons (19,000,000 m3) shall come from biomass-based diesel and other advanced biofuels. For sources other than biofuels, The United States carries no mandatory renewable energy targets although they do support the growth of renewable energy industries with subsidies, feed-in tariffs, tax exemptions, and other financial support measures.
