The National Federation of Energy (French: Fédération nationale de l'énergie, FNE-CGT) was a trade union representing workers in the energy industry, in France. The union was founded in 1905 as the National Federation of Lighting Workers, affiliated to the General Confederation of Labour (CGT), and mostly represented gas workers. In 1919, it was joined by various unions representing electrical workers, which had previously been part of the National Federation of Metalworkers, and it renamed itself as the National Federation of Lighting and Motive Force Workers. Following lengthy debates, the union decided not to affiliate to the Red Trade Union International.
