The energy sector in Switzerland is, by its structure and importance, typical of a developed country.Apart from hydroelectric power and firewood, the country has few indigenous energy resources: oil products, natural gas and nuclear fuel are imported, so that by 2013 only 22.6% of primary energy consumption will have been 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 energy policy 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 CO2 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.
This "2050 energy strategy" was accepted by 58.2% of the population in a popular vote on May 21, 2017, and the new legislation came into force in 2018.
The energy economy in Switzerland developed similarly to the rest of Europe, but with some delay until 1850. There are three different periods. An agrarian society until the mid-nineteenth century, Switzerland's small scale energy economy was based on wood and biomass (plants feeding the animal and human labour), which was in general renewable energy. Also used were wind power and hydraulic power, and, from the eighteenth century, indigenous coal.
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 nuclear energy. 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.
On 21 May 2017, Swiss voters accepted the new Energy Act establishing the 'energy strategy 2050'. The aims of the energy strategy 2050 are:
The Energy Act of 2006 forbids the construction of new nuclear power plants in Switzerland.
|Mtoe = 11.63 TWh.|
The Swiss government has set a target to cut fossil fuel use 20% by the year 2020 [ needs update ] Most of the energy produced within Switzerland is renewable from Hydropower and biomass. 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.
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.
There has been a proposal to produce around 600 GWh (< 0.2%) of electricity per annum using wind turbines by 2030.
Solar energy 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.
Switzerland's per capita electricity consumption is slightly higher than that of its neighbours.
Production of electricity (2008):
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.
A report was published in 2011 by the World Energy Council in association with Oliver Wyman, entitled Policies for the future: 2011 Assessment of country energy and climate policies, which ranks country performance according to an energy sustainability index.The best performers were Switzerland, Sweden and France.
A study published in 2009 showed that the emissions of carbon dioxide (CO
2) due to the electricity consumed in Switzerland (total: 5.7 million tonnes) are seven times higher than the emissions of carbon dioxide due to the electricity produced in Switzerland (total: 0.8 million tonnes).
The study also showed that the production in Switzerland (64.6 TWh) is similar to the amount of electricity consumed in the country (63.7 TWh). CO

Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery to end users or its storage.
Energy in Japan refers to energy and electricity production, consumption, import and export in Japan. The country's primary energy consumption was 477.6 Mtoe in 2011, a decrease of 5% over the previous year.
Energy in the United States comes mostly from fossil fuels: in 2010, data showed that 25% of the nation's energy originates from petroleum, 22% from coal, and 22% from natural gas. Nuclear power supplied 8.4% and renewable energy supplied 8%, mainly from hydroelectric dams and biomass; however, this also includes other renewable sources like wind, geothermal, and solar. Data from 2019 shows that 37% of the nation's energy originates from petroleum, 32% from natural gas, 11% from coal, 11% from renewable energy, and 8% from nuclear power.
Renewable energy in Germany is mainly based on wind, solar and biomass. Germany had the world's largest photovoltaic installed capacity until 2014, and as of 2020 it has 49 GW. It is also the world's third country by installed wind power capacity, at 59 GW in 2018, and second for offshore wind, with over 4 GW. Germany has been called "the world's first major renewable energy economy".
Denmark has considerable sources of oil and natural gas in the North Sea and ranked as number 32 in the world among net exporters of crude oil in 2008. Denmark expects to be self-sufficient with oil until 2050. However, gas resources are expected to decline, and production may decline below consumption in 2020, making imports necessary. Denmark imports around 12% of its energy.

Production by power source in 2009 was 53% nuclear, 40% fossil electricity and 7% renewable electricity. 2% of production was exported in 2009. In 2008 import was 11%. Belgium is highly nuclear dependent country where the share of renewable electricity has been low. The share of renewable electricity was about 2% in 2005. Plan for 2020 is wind 10.5 TWh (9.5%), biomass 11 TWh and PV 1 TWh.
The electricity sector in Switzerland relies mainly on hydroelectricity, since the Alps cover almost two-thirds of the country's land mass, providing many large mountain lakes and artificial reservoirs suited for hydro power. In addition, the water masses drained from the Swiss Alps are intensively used by run-of-the-river hydroelectricity (ROR). With 9,052 kWh per person in 2008, the country's electricity consumption is relatively high and was 22% above the European Union's average.
Primary energy consumption in Spain in 2015 was mainly composed of fossil fuels. The largest sources are petroleum (42.3%), natural gas (19.8%) and coal (11.6%). The remaining 26.3% is accounted for nuclear energy (12%) and different renewable energy sources (14.3%). Domestic production of primary energy includes nuclear (44,8%), solar, wind and geothermal (22,4%), biomass and waste (21,1%), hydropower (7,2%) and fossil (4,5%).

Although there are plenty of renewable resources for energy in Turkey, only hydropower has been much developed, averaging about a fifth of national electricity supply. However because this is vulnerable to droughts less electricity than usual is from hydro in those recent years, compared to around a third in a wet year. The country is aiming for two thirds of electricity to be from renewables by 2023 but Turkey has invested less in solar and wind power than similar Mediterranean countries. Turkey needs a renewable energy plan beyond 2023 which includes transport, industry, heating and cooling as well as electricity generation. Turkey is a net exporter of wind power equipment but a net importer of solar power equipment.
Denmark is a world-leading country in wind energy production and wind turbine production. The Danish wind company Vestas Wind Systems A/S has expanded from its domestic base and by 2015 had a revenue of €8.423 billion, with more than 18,000 employees globally and manufacturing plants in Denmark, Germany, India, Italy, Romania, the United Kingdom, Spain, Sweden, Norway, Australia, China, and the United States. Wind power alone produced 47% of Denmark's electricity consumption in 2017, and is expected to increase its production by nearly 80% in the years to 2024.
World energy supply and consumption is global production and preparation of fuel, generation of electricity, energy transport and energy consumption. It is a basic part of economic activity. It does not include energy from food.
