Electricity generated in Switzerland is 56% from hydroelectricity and 39% from nuclear power, resulting in a nearly CO2-free electricity-generating network. On 18 May 2003, two anti-nuclear initiatives were turned down: ''Moratorium Plus'', aimed at forbidding the building of new nuclear power plants (41.6% supported and 58.4% opposed), and Electricity Without Nuclear (33.7% supported and 66.3% opposed) after a previous moratorium expired in 2000. However, as a reaction to the Fukushima nuclear disaster, the Swiss government announced in 2011 that it plans to end its use of nuclear energy in the next 2 or 3 decades. In November 2016, Swiss voters rejected a proposal by the Green Party to accelerate the phaseout of nuclear power (45.8% supported and 54.2% opposed). The Swiss Federal Office of Energy (SFOE) is the office responsible for all questions relating to energy supply and energy use within the Federal Department of Environment, Transport, Energy and Communications (DETEC). The agency is supporting the 2000-watt society initiative to cut the nation's energy use by more than half by the year 2050.
