Fusion Energy Foundation (FEF) was an American non-profit think tank co-founded by Lyndon LaRouche in 1974 in New York. It promoted the construction of nuclear power plants, research into fusion power and beam weapons and other causes. The FEF was called fusion's greatest private supporter. It was praised by scientists like John Clarke, who said that the fusion community owed it a "debt of gratitude". By 1980, its main publication, Fusion, claimed 80,000 subscribers.
