"EIA's updated Reference case shows how evolving consumer preferences, improved technology, and economic changes are pushing the nation toward more domestic energy production, greater vehicle efficiency, greater use of clean energy and reduced energy imports," said EIA Administrator Adam Sieminski. "This combination has markedly reduced projected energy-related carbon dioxide emissions," said Mr. Sieminski.
Renewable fuel use grows at a much faster rate than fossil fuel use. The share of electricity generation from renewables grows from 13 percent in 2011 to 16 percent in 2040. Electricity generation from solar and, to a lesser degree, wind energy sources grows as recent cost declines make them more economical. However, the AEO2013 projection is less optimistic about the ability of advanced biofuels to capture a rapidly growing share of the liquid fuels market than AEO2012. As a result, biomass use in AEO2013 totals 4.2 quadrillion Btu by 2035 (compared to 5.4 quadrillion Btu in AEO2012) and 4.9 quadrillion Btu in 2040, up from 2.7 quadrillion Btu in 2011.
