The Annual Energy Outlook 2010 (AEO2010) reference case by the
U.S. Energy Information Administration (EIA) presents updated
projections for U.S. energy consumption and production through
2035. “Our projections show that existing policies that stress
energy efficiency and alternative fuels, together with higher
energy prices, curb energy consumption growth and shift the
energy mix toward renewable fuels,” said Richard Newell, EIA
administrator. “However, assuming no new policies, fossil fuels
would still provide about 78 percent of all the energy used in
2035.” These reference case projections do not include the
effects of potential future policies that have not yet become
law and only include technologies that are commercially
available or can reasonably be expected to become commercially
available over roughly the next decade. The report predicts
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
