The Annual Energy Outlook 2010 reference case released by the U.S. Energy Information Administration projects total primary energy consumption to grow by 14 percent between 2008 and 2035, as the fossil fuel share of total U.S. energy consumption falls from 84 percent to 78 percent. Total U.S. consumption of liquid fuels, including both fossil liquids and biofuels, grows from 19 million barrels per day in 2008 to 22 million barrels per day in 2035; biofuels account for all of the growth. The renewable share of electricity generation grows from 9 percent of generation in 2008 to 17 percent of generation in 2035. CO2 emissions from energy are projected to grow at 0.3 percent per year; total energy-related CO2 emissions grow from 5,814 million metric tons in 2008 to 6,320 million metric tons in 2035, although per capita emissions fall by 0.6 percent per year.
