. Apart from
hydroelectric power and
firewood, the country has few indigenous energy resources: oil products, natural gas and nuclear fuel are imported, so that in 2013 only 22.6% of primary energy consumption were covered by local resources.
Final energy consumption in
Switzerland has increased more than fivefold since the beginning of the 20th century, from around 170,000 to 896,000 terajoules per year, with the largest share now being captured by transport (35% in 2013). This increase was made in parallel with the strong development of its economy and the increase in population. As the sector is highly liberalised, the federal

aims to accompany the promises made in Kyoto by promoting a more rational use of energy and, particularly since the 1990s, the development of new renewable sources.
Thanks to the high share of hydroelectricity (59.6%) and nuclear power (31.7%) in electricity production, Switzerland's per capita energy-related emissions are 28% lower than the European Union average and roughly equal to those of France.
Following the earthquake that struck Japan in March 2011 and the Fukushima nuclear accident, the Federal Council announced on 25 May 2011 a phase-out of nuclear energy scheduled for 2034.
In September 2016, both chambers of the
Swiss Parliament voted for the ''Energiestrategie 2050'', a set of measures to replace electrical energy produced by atomic reactors with renewable energy, reduce the use of
fossil fuel and increase the efficiency of energy consumption. This decision was challenged by a national

The industrial society, from 1860 to 1950, had to import coal as it was the main source of energy but not readily available as a natural resource. Another important source of energy was water power at low or high pressure. The current consumer society, developed using mostly oil, natural gas, water power (turbines) to a lesser extent, and later

. The oil crisis and pollution of the environment prompted the increased use of
renewable energy. It is notable that 100% of the Swiss railway network is electrified. The high proportion of energy generated through hydroelectric power and the lack of natural resources (such as coal and oil) help to explain why such a situation is strategically beneficial in Switzerland.

Overview
Renewable energy in Switzerland
The Swiss government has set a target to cut fossil fuel use 20% by the year 2020. Most of the energy produced within Switzerland is renewable from hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of ...

Biomass is plant-based material used as a fuel for heat or electricity production. It can be in the form of wood, wood residues, energy crops, agricultural residues, and waste from industry, farms, and households. Some people use the terms biom ...
. However this only accounts for around 15% of total overall energy consumption as the other 85% of energy used is imported, mostly derived from fossil fuels.
Hydro
Based on the estimated mean production level, hydropower still accounted for almost 90% of domestic electricity production at the beginning of the 1970s, but this figure fell to around 60% by 1985 following the commissioning of Switzerland's nuclear power plants, and is now around 56%. Hydropower therefore remains Switzerland's most important domestic source of renewable energy.
Hydro energy was meaning to be taken down in 2013 with new laws on energy to be put in place but they were scrapped for a more eco friendly plan.
Hydroelectric companies received support from the state (for instance in the 2010s). Critics pointed out the lack of independence of the political institutions (cantonal and federal), of which several elected members are connected with the hydroelectric industry.
Wind
There has been a proposal to produce around 600 GWh (< 0.2%) of electricity per annum using wind turbines by 2030. Switzerland's wind power potential is several TWh per year.
Solar

Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy (including solar water heating), and solar architecture. It is an ...
in Switzerland currently only accounts for 0.04% of total energy production. Currently the cost of solar energy is significantly higher than competing sources in Switzerland such as hydro. As costs of solar come down it is likely to become more market competitive. It is currently subsidised in an attempt to make it more competitive and attractive.
2019 Switzerland announced plans of large scale solar auctions.
Electricity
Switzerland's per capita electricity consumption is slightly higher than that of its neighbours.
Production of electricity (2008):
* Hydropower plants, 56%
* Nuclear power plants, 39%
* Thermal power
A thermal power station is a type of power station in which heat energy is converted to electrical energy. In a steam-generating cycle heat is used to boil water in a large pressure vessel to produce high-pressure steam, which drives a s ...

The Swiss Federal Office of Energy (SFOE) is within the Federal Department of Environment, Transport, Energy and Communications (DETEC). SwissEnergy is a program aiming at promoting energy efficiency and the use of renewable energy with the collaboration of the cantons and municipalities, and partners from trade and industry, environmental and consumer organisations.

The study also showed that the production in Switzerland (64.6 TWh) was similar to the amount of electricity consumed in the country (63.7 TWh).[ Overall, Switzerland exported 7.6 TWh and imported 6.8 TWh; but, in terms of emissions of carbon dioxide, Switzerland exported "clean" electricity causing emissions of 0.1 million tonnes of and imported "dirty" electricity causing emissions of 5 million tonnes of .][
