The Western U.S. could reap huge benefits in pollution savings and reduced spending on fossil fuels by installing more wind and solar power plants, according to a comprehensive new analysis released today by the National Renewable Energy Laboratory (NREL). The study found that obtaining 25 percent of electricity in the Western U.S. from renewable energy will reduce carbon dioxide pollution by up to 34 percent and save $7 billion annually in fossil fuel costs.
The NREL report also conclusively puts to rest the fossil fuel industry myth that wind energy’s pollution savings are smaller than expected because fossil-fired power plants run at lower efficiency when wind is generating electricity. Even at the very high level of renewable energy use examined in the report, the impact on the efficiency of fossil-fired power plants was found to be “negligible,” reducing the carbon emissions reduction benefits of wind and solar by only 0.2 percent, so that on net wind and solar produced 99.8 percent of the expected emissions savings.
