The first form of feed-in tariff (under another name ) was implemented in the US in 1978 under President Jimmy Carter, who signed the National Energy Act (NEA). This law included five separate acts, one of which was the Public Utility Regulatory Policies Act (PURPA). The purpose of the National Energy Act was to encourage energy conservation and develop new energy resources, including renewables such as wind, solar, and geothermal power.
