Energy efficiency
The fastest and most affordable way to get our country’s energy use under control is to make our homes, businesses and communities more energy efficient.
Energy experts estimate that we can reduce our overall energy usage by 50 percent below current levels in the next 30 years, simply by using better technologies and eliminating waste across our economy. Reducing energy use creates big savings—for our planet, our climate and our health. More efficient energy use will clean up our air and help combat climate change.
