The primary sources of electricity generation in Scotland are provided through renewable energy (61.8%), nuclear (25.7%) and fossil fuel generation (10.9%). [1] Whitelee Wind Farm is the largest onshore wind farm in the United Kingdom, and was Europe's largest onshore wind farm for some time. [2] Tidal power is an emerging source of renewable energy in Scotland. The MeyGen tidal stream energy plant in the north of the country is claimed to be the largest tidal stream energy project in the world. [3]
The total final energy consumption in Scotland was just over 64.5 TWh, split approximately two-thirds gas to one-third electricity. Both gas and electricity consumption has continued to decline, down 70% and 74% from 2005 levels respectively. [4]
Domestic | Non-domestic | Total | |
---|---|---|---|
Gas | 25,133 (+1.1%) | 17,608 (-1.9%) | 42,741 (-2.0%) |
Electricity | 8,694 (+2%) | 13,068 (-7%) | 21,763 (-0.7%) |
Total | 33,827 | 30,676 | 64,504 |
In 2020, 98.6% of all electricity used in Scotland was from renewable sources. This is minus net exports. [1] Between October 2021 and September 2022 63.1% of all electricity generated in Scotland was from renewable sources, 83.6% was classed as low carbon and 14.5% was from fossil fuels. [5] The Scottish Government has a target to have the equivalent of 50% of the energy for Scotland's heat, transport and electricity consumption to be supplied from renewable sources by 2030. [6] They have stated that, in 2022, the equivalent of 113% of the country's overall electrical consumption was produced by renewable energy, making it the highest recorded figure of renewable energy generated to date. [7]
Over the past two decades, the annual electricity generation in Scotland has been around 50 TWh. Prior to 2010, around half of this was from fossil fuels. There has been significant growth in wind power, which now comprises more than half of all electricity generation in Scotland. Bioenergy contributes around 5% and grid-scale solar power almost 1%. [8] In 2023, Scotland exported 13.85 TWh to England and 2.03 TWh to Northern Ireland, approximately 35% of the total generated. [9]
Scotland has a long history of nuclear research and electricity generation. Nuclear energy consistently accounts for 20-80% of the electric supply in Scotland depending on weather conditions for wind power generation and electricity demand. [10] As of 2022, there is only one remaining operating nuclear power station in Scotland (Torness). [11]
The Scottish National Party (SNP) government elected in 2007 had a 'no new nuclear power strategy'. This position is at odds with UK government policy which in January 2008 announced the go-ahead for new nuclear power stations to be built across the United Kingdom. In response, Scotland's then First Minister Alex Salmond commented there was 'no chance' of new nuclear power stations being built in Scotland. [12] The Parliament voted 63–58 to support the policy of opposing new nuclear power stations, [13] taking advantage of a loophole which permits a veto on planning, despite lacking authority over the UK energy policy. [13] Others support nuclear as part of a sustainable, clean energy policy. [14]
The production of renewable energy in Scotland is a topic that came to the fore in technical, economic, and political terms during the opening years of the 21st century. [15] The natural resource base for renewable energy is high by European, and even global standards, with the most important potential sources being wind, wave, and tide. Renewables generate almost all of Scotland's electricity, mostly from the country's wind power. [16]
In 2020, Scotland had 12 gigawatts (GW) of renewable electricity capacity, which produced about a quarter of total UK renewable generation. [17] In decreasing order of capacity, Scotland's renewable generation comes from onshore wind, hydropower, offshore wind, solar PV and biomass. Scotland exports much of this electricity. [18] [19] On 26 January 2024, the Scottish Government confirmed that 113% of Scotland's overall electricity consumption in 2022 was from renewable energy sources, making it the highest percentage figure ever recorded for renewable energy consumption in Scotland. It was hailed as "a significant milestone in Scotland's journey to net zero" by the Cabinet Secretary for Wellbeing Economy, Fair Work and Energy, Neil Gray. It becomes the first time that Scotland produced more renewable energy than it actually consumed, and demonstrates the "enormous potential of Scotland's green economy" as claimed by Gray. [20]
Continuing improvements in engineering and economics are enabling more of the renewable resources to be used. Fears regarding fuel poverty [21] and climate change have driven the subject high up the political agenda. In 2020 a quarter of total energy consumption, including heat and transportation, was met from renewables, and the Scottish government target is half by 2030. [22] Although the finances of some projects remain speculative or dependent on market incentives, there has been a significant—and, in all likelihood, long-term—change in the underpinning economics.
98% of oil and gas production in the United Kingdom as a whole comes from offshore fields [23] and the services industry in Aberdeen has been a leader in developing technology for hydrocarbon extraction offshore.
Oil comes mainly from the North Sea Central Graben close to the median line with Norway in two main clusters – around the Forties oilfield east of Aberdeen and the Brent oilfield east of Shetland. There have been recent discoveries in challenging conditions west of Shetland. [24]
Most of the largest oil fields in the UK sector of the North Sea were found in the waters to the north and east of the Scottish mainland, with the most northerly fields found to the east of the Orkney and the Shetland Islands. [25] Aberdeen became the centre of Britain's North Sea oil industry, with many oil terminals such as that of Sullom Voe in Shetland and Flotta in Orkney and at Cruden Bay and St Fergus on the north-eastern coast of Scotland being built to support the North Sea oil industry. In the early 1970s, there was a great deal of economic turbulence with the 1973 oil price shock, which was caused by the Yom Kippur War. That resulted in rising inflation, high unemployment and a recession, a situation known as stagflation, in Scotland and the rest of the United Kingdom. [26]
The Renewables Obligation (RO) is a market support mechanism designed to encourage generation of electricity from eligible renewable sources in the United Kingdom. There are three related schemes for the three legal jurisdictions of the UK. In April 2002 the Renewables Obligation was introduced in England and Wales, and in Scotland as the Renewables Obligation (Scotland). The RO was later introduced in Northern Ireland in April 2005. In all cases, the RO replaced the Non-Fossil Fuel Obligation which operated from 1990.
Renewable energy progress in the European Union (EU) is driven by the European Commission's 2023 revision of the Renewable Energy Directive, which raises the EU's binding renewable energy target for 2030 to at least 42.5%, up from the previous target of 32%. Effective since November 20, 2023, across all EU countries, this directive aligns with broader climate objectives, including reducing greenhouse gas emissions by at least 55% by 2030 and achieving climate neutrality by 2050. Additionally, the Energy 2020 strategy exceeded its goals, with the EU achieving a 22.1% share of renewable energy in 2020, surpassing the 20% target.
About half of the energy in the United Kingdom came from fossil fuels in 2023. Total energy consumption in the United Kingdom was 142.0 million tonnes of oil equivalent in 2019. In 2014, the UK had an energy consumption per capita of 2.78 tonnes of oil equivalent compared to a world average of 1.92 tonnes of oil equivalent. Demand for electricity in 2023 was 29.6 GW on average, supplied through 235 TWh of UK-based generation and 24 TWh of energy imports.
The energy policy of the United Kingdom refers to the United Kingdom's efforts towards reducing energy intensity, reducing energy poverty, and maintaining energy supply reliability. The United Kingdom has had success in this, though energy intensity remains high. There is an ambitious goal to reduce carbon dioxide emissions in future years, but it is unclear whether the programmes in place are sufficient to achieve this objective. Regarding energy self-sufficiency, UK policy does not address this issue, other than to concede historic energy security is currently ceasing to exist.
The United Kingdom is the best location for wind power in Europe and one of the best in the world. The combination of long coastline, shallow water and strong winds make offshore wind unusually effective.
Energy in the United States is obtained from a diverse portfolio of sources, although the majority came from fossil fuels in 2023, as 38% of the nation's energy originated from petroleum, 36% from natural gas, and 9% from coal. Electricity from nuclear power supplied 9% and renewable energy supplied 9%, which includes biomass, wind, hydro, solar and geothermal.

The natural resource base for renewable energy is high by European, and even global standards, with the most important potential sources being wind, wave, and tide. Renewables generate almost all of Scotland's electricity, mostly from the country's wind power.
As of 2023, Europe had a total installed wind capacity of 255 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.
Brazil is the 7th largest energy consumer in the world and the largest in South America. At the same time, it is an important oil and gas producer in the region and the world's second largest ethanol fuel producer. The government agencies responsible for energy policy are the Ministry of Mines and Energy (MME), the National Council for Energy Policy (CNPE), the National Agency of Petroleum, Natural Gas and Biofuels (ANP) and the National Agency of Electricity (ANEEL). State-owned companies Petrobras and Eletrobras are the major players in Brazil's energy sector, as well as Latin America's.
Wind power is the fastest-growing renewable energy technology in Scotland, with 16,648 megawatts (MW) of installed wind power capacity by Q2 2024. This included 9,756 MW from onshore wind in Scotland and 2,971 MW of offshore wind generators. The largest onshore wind farm in the UK is Whitelee, just south of Glasgow, with 215 turbines and a total capacity of 539 MW.
Renewable energy in the United Kingdom contributes to production for electricity, heat, and transport.
Whitelee Wind Farm is a windfarm on the Eaglesham moor in Scotland. The main visitor centre is located in East Renfrewshire, but the majority of turbines are located in East Ayrshire and South Lanarkshire. It is the largest on-shore wind farm in the United Kingdom with 215 Siemens and Alstom wind turbines and a total capacity of 539 megawatts (MW), with the average of 2.5 MW per turbine. Whitelee was developed and is operated by ScottishPower Renewables, which is part of the Spanish company Iberdrola.
Energy in Finland describes energy and electricity production, consumption and import in Finland. Energy policy of Finland describes the politics of Finland related to energy. Electricity sector in Finland is the main article regarding electricity in Finland.
The National Grid covers most of mainland Great Britain and several of the surrounding islands, and there are interconnectors to Northern Ireland and to other European countries. Power is supplied to consumers at 230 volts AC with a frequency of 50 Hz. In 2023 about a third of electricity used in Britain was generated from fossil gas and two-thirds was low-carbon power. Wind generates the most low-carbon power, followed by nuclear some of which is imported from France. The government is aiming for greenhouse gas emissions from electricity in Britain to be net zero by 2035.
The electricity sector in France is dominated by its nuclear power, which accounted for 71.7% of total production in 2018, while renewables and fossil fuels accounted for 21.3% and 7.1%, respectively. France has the largest share of nuclear electricity in the world, and together with renewable energy supplies, this has helped its grid achieve very low carbon intensity.
Estonia's electricity sector is interconnected with regional energy markets, particularly through connections with Finland, Latvia, and Russia. The direct electrical interconnection with Finland was established in 2006 and was further strengthened by the Estlink 2 interconnector in 2014. Estonia joined the Nord Pool Spot market by 2012, securing its own price area within this regional electricity market.
Total primary energy supply (TPES) in Slovenia was 6.80 Mtoe in 2019. In the same year, electricity production was 16.1 TWh, consumption was 14.9 TWh.
Denmark is a leading country in renewable energy production and usage. Renewable energy sources collectively produced 81% of Denmark's electricity generation in 2022, and are expected to provide 100% of national electric power production from 2030. Including energy use in the heating/cooling and transport sectors, Denmark is expected to reach 100% renewable energy in 2050, up from the 34% recorded in 2021.
In 2019, Wales generated 27% of its electricity consumption as renewable electricity, an increase from 19% in 2014. The Welsh Government set a target of 70% by 2030. In 2019, Wales was a net exporter of electricity. It produced 27.9 TWh of electricity while only consuming 14.7 TWh. The natural resource base for renewable energy is high by European standards, with the core sources being wind, wave, and tidal. Wales has a long history of renewable energy: in the 1880s, the first house in Wales with electric lighting powered from its own hydro-electric power station was in Plas Tan y Bwlch, Gwynedd. In 1963, the Ffestiniog Power Station was constructed, providing a large scale generation of hydroelectricity, and in November 1973, the Centre for Alternative Technology was opened in Machynlleth.
Energy in Wales is the production of electricity in Wales.
