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.
The electric power industry covers the generation, transmission, distribution and sale of electric power to the general public and industry. The commercial distribution of electric power started in 1882 when electricity was produced for electric lighting. In the 1880s and 1890s, growing economic and safety concerns lead to the regulation of the industry. What was once an expensive novelty limited to the most densely populated areas, reliable and economical electric power has become an essential aspect for normal operation of all elements of developed economies.
Hydroelectricity, or hydroelectric power, is electricity produced from hydropower. In 2015, hydropower generated 16.6% of the world's total electricity and 70% of all renewable electricity, and was expected to increase by about 3.1% each year for the next 25 years.
Renewable energy plays an important and growing role in the energy system of the European Union. The share of energy from renewable sources in gross final consumption of energy was 18% in 2018. This is double the share in 2004 with 8.5%. The Europe 2020 strategy includes a target of reaching 20% of gross final energy consumption from renewable sources by 2020, and at least 32% by 2030. These figures are based on energy use in all its forms across all three main sectors, the heating and cooling sector, the electricity sector and the transport sector.
Energy use in the United Kingdom stood at 2,249 TWh in 2014. This equates to energy consumption per capita of 34.82 MWh compared to a 2010 world average of 21.54 MWh. Demand for electricity in 2014 was 34.42GW on average coming from a total electricity generation of 335.0TWh.
Electric energy consumption is the form of energy consumption that uses electric energy. Electric energy consumption is the actual energy demand made on existing electricity supply.
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.
World energy consumption is the total energy produced and used by humans. Typically measured per year, it involves all energy harnessed from every energy source applied towards activity across all industrial and technological sectors, in every country. It does not include energy from food. World energy consumption has implications for the socio-economic-political sphere.
Energy in France is the energy and electricity production, consumption, and import in France.
As of December 2017, installed capacity of wind power in the European Union totaled 169.3 gigawatts (GW). In 2017, a total of 15,680 MW of wind power was installed, representing 55% of all new power capacity, and the wind power generated 336 TWh of electricity, enough to supply 11.6% of the EU's electricity consumption.
Low-carbon power is electricity produced with substantially lower greenhouse gas emissions than conventional fossil fuel power generation. The energy transition to low-carbon power is one of the most important actions required to limit climate change. Power sector emissions may have peaked in 2018.
Energy in Australia is the production in Australia of energy and electricity, for consumption or export. Energy policy of Australia describes the politics of Australia as it relates to energy.
Majority of electricity production in Sweden relies on hydro power and nuclear power. In 2008 the consumption of electricity in Sweden was 16018 kWh per capita, compared to EU average 7409 kWh per capita. A specialty of the Nordic energy market is the existence of so-called electricity price areas, which complicate the wholesale commodity market.
Russia is the fourth largest generator and consumer of electricity in the world. Its 440 power stations have a combined installed generation capacity of 220 GW.
Energy in Sweden describes energy and electricity production, consumption and import in Sweden. Electricity sector in Sweden is the main article of electricity in Sweden. The Swedish climate bill of February 2017 aims to make Sweden carbon neutral by 2045. The Swedish target is to decline emission of climate gases 63% from 1990 to 2030 and international transportation excluding foreign flights 70%. By 2014 just over half of the country's total final energy consumption in electricity, heating and cooling and transport combined was provided by renewables, the highest share amongst the 28 EU member countries. About a third of Sweden's electricity is generated by nuclear power. In generating a year's worth of this energy, Swedes generate about 4 tonnes of CO2 emissions each. Since 2010, sustainability measures have reduced total emissions even as the population has increased.
Lithuania is a net energy importer. Primary energy use in Lithuania was 98 TWh, or 29 TWh per million people in 2009.
Solar power in Lithuania is a form of renewable energy in Lithuania, and created 39 GWh of electricity in the first nine months of 2013. At 2020 Lithuania had capacity of 120 MW of solar power.
Litgrid AB is a Lithuanian electricity transmission system operator that manages Lithuania’s electricity transmission grid. Litgrid is responsible for the integration of the Lithuanian electricity system into the European electricity infrastructure and the common electricity market. Litgrid completed the strategic international connection projects NordBalt (Lithuania-Sweden) and LitPol Link (Lithuania-Poland), and currently it is implementing Lithuania's strategic objective of reorienting its power system for synchronous operation with the continental European power grid. The company employs over 200 specialists.
The Nigerian energy supply crisis refers to the ongoing failure of the Nigerian power sector to provide adequate electricity supply to domestic households and industrial producers despite a rapidly growing economy, some of the world's largest deposits of coal, oil, and gas and the country's status as Africa's largest oil producer. Currently, only 40% of Nigeria's population is connected to the energy grid whilst power supply difficulties are experienced around 60% of the time. At best, average daily power supply is estimated at four hours, although several days can go by without any power at all. Neither power cuts nor restorations are announced, leading to calls for a load shedding schedule during the COVID-19 lockdowns to aid fair distribution and predictability.
The energy crisis in Armenia, popularly known as the dark and cold years, refers to the energy crisis in Armenia during the 1990s, when the newly independent Armenia's population lived in shortage of energy and basic consumer goods. Although it only lasted 3–4 years, it left a deep impact and impression. Local people have dubbed the years from 1992 to 1995 in different ways, such as "hungry", "cold", and "bad", but the most common title used is "the dark."
