Switzerland's energy consumption is fed mainly by imported, non-renewable sources. The Energy Strategy 2050, launched by the Federal Council in 2011, seeks to reduce consumption and promote the use of more sustainable sources of energy.
Switzerland's main sources of energy are oil, nuclear and hydroelectric power and natural gas. Around 80% of Switzerland's energy consumption is fed by non-renewable, imported sources. In 2011, Switzerland embarked on an energy transition to reduce its reliance on imports of fossil fuels.
The new energy strategy, which will be implemented in stages, aims by 2050 to massively reduce energy consumption and significantly increase the share of renewables in Switzerland's energy mix. Switzerland's nuclear power plants are to be decommissioned at the end of their operating lives.
