Renewables Provide 7% of U.S. energy
Renewable energy provides seven quads of energy or just under 7 percent of the entire U.S. Energy budget, according to figures released by the Energy Information Administration. The EIA projects that this will climb to 8 quads by 2015.
More than half of this, it should be noted, comes from hydroelectricity and burning wood for home heating, technologies that were in place long before the current push for renewables began. Biofuels as liquids is the corn ethanol effort. Wind contributes two quads but solar and geothermal, two of the more highly touted renewable resources, still only constitute a tiny sliver. However, both are expected to grow.
