The National Energy Conservation Policy Act (NECPA) was enacted in 1978 to promote energy conservation and efficiency in the United States. It established a framework for federal, state, and local governments to implement energy-saving measures and encouraged the use of renewable energy sources. The act also aimed to reduce the nation's dependence on foreign oil. NECPA led to the creation of various programs and initiatives, including the establishment of energy efficiency standards for appliances and buildings. It also facilitated the development of energy conservation plans, helping to raise public awareness about the importance of energy efficiency and sustainable practices.
