The National Energy Act was a comprehensive piece of legislation enacted in 1978 aimed at reducing U.S. dependence on foreign oil and promoting energy conservation and the development of alternative energy sources. The act included measures such as tax incentives for renewable energy, regulations on energy consumption, and initiatives to increase energy efficiency. This legislation emerged during a time of energy crisis and economic stagnation, and it sought to address the challenges of rising oil prices and the effects of stagflation on the American economy.
