Energy efficiency is America’s largest energy resource, contributing more to the nation’s energy needs over the last 40 years than oil, coal, natural gas, or nuclear power. It accounts for more than million . jobs—at least 10 times more than oil and gas drilling or coal mining. NRDC helped pioneer the first appliance standards and the first efficiency programs for utilities. Today we work to increase efficiency everywhere, from community revitalization to state and national climate policy to China’s and India’s economic growth strategies.
