Report on Impacts of Renewable Energy Use

Santa Monica, California [] RAND assessed the possible impact that a 25-percent renewable energy target for electricity and motor vehicle ground transportation could have on total national energy expenditures and on emissions of local air pollutants and carbon dioxide by the year 2025. Currently, 6 percent of America’s energy use comes from renewable sources, including hydropower. The authors estimate that about 18 percent of total demand in 2025 could be met by renewables. Further, as renewable energy supplants nonrenewable energy, demand for fuels declines, driving down the prices of fossil fuels in the model. The authors (Mark A. Bernstein, Jay Griffin, Robert Lempert) identified potential critical points and ranges where changes in the prices of oil, gas, coal, or renewable technologies will take effect.
