On April 30, the Energy Information Administration (EIA) published its Annual Energy Outlook 2013 case study. The report found that extending energy efficiency and renewable energy policies, specifically the production and investment tax credits, could result in the reduction of carbon dioxide emissions by approximately 6 percent between 2013 and 2040. The production tax credit is for biomass, geothermal, and wind energy while the investment tax credit is for solar energy technology; both tax credits are currently temporary. The report assumed that there would be a decrease in demand for energy and an increase of low-carbon energy generation.
