The primary sources of energy 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 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]
In Scotland, 98.6% of all electricity used 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. [4] 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. [5] 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. [6]
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. [7] As of 2022, there is only one remaining operating nuclear power station in Scotland (Torness). [8]
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. [9] The Parliament voted 63–58 to support the policy of opposing new nuclear power stations, [10] taking advantage of a loophole which permits a veto on planning, despite lacking authority over the UK energy policy. [10] Others support nuclear as part of a sustainable, clean energy policy. [11]
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. [12] 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. [13]
In 2020, Scotland had 12 gigawatts (GW) of renewable electricity capacity, which produced about a quarter of total UK renewable generation. [14] 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. [15] [16] 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. [17]
Continuing improvements in engineering and economics are enabling more of the renewable resources to be used. Fears regarding fuel poverty [18] 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. [19] 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 [20] 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. [21]
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. [22] 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. [23]
The Renewables Obligation (RO) is designed to encourage generation of electricity from eligible renewable sources in the United Kingdom. It was introduced in England and Wales and in a different form in Scotland in April 2002 and in Northern Ireland in April 2005, replacing the Non-Fossil Fuel Obligation which operated from 1990.
Japan's primary energy consumption was 477.6 Mtoe in 2011, a decrease of 5% over the previous year. The country lacks significant domestic reserves of fossil fuel, except coal, and must import substantial amounts of crude oil, natural gas, and other energy resources, including uranium. Japan relied on oil imports to meet about 84% of its energy needs in 2010. Japan was also the first coal importer in 2010, with 187 Mt, and the first natural gas importer with 99 bcm. As of 2019, 88% of Japan's total primary energy supply came from fossil fuels.
Energy in the United Kingdom came mostly from fossil fuels in 2021. 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 2014 was 34.42 GW on average coming from a total electricity generation of 335.0 TWh.
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 independence is independence or autarky regarding energy resources, energy supply and/or energy generation by the energy industry.
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.
Wind power is the fastest-growing renewable energy technology in Scotland, with 11,482 megawatts (MW) of installed wind power capacity by Q1 2023. This included 9,316 MW from onshore wind in Scotland and 2,166 MW of offshore wind generators.
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.
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. As of 2022, there is only one remaining operating nuclear power station in Scotland (Torness).
Climate change in Scotland is causing a range of impacts on Scotland, and its mitigation and adaptation is a matter for the devolved Scottish Parliament. Climate change has already changed timings of spring events such as leaf unfolding, bird migration and egg-laying. Severe effects are likely to occur on biodiversity.
Energy in Malta describes energy production, consumption and import in Malta. Malta has no domestic resource of fossil fuels and no gas distribution network, and relies overwhelmingly on imports of fossil fuels and electricity to cover its energy needs. Since 2015, the Malta–Sicily interconnector allows Malta to be connected to the European power grid and import a significant share of its electricity.
The United Kingdom has a National Grid that covers most of mainland Great Britain and several of the surrounding islands, as well as some connectivity to other countries. The electrical sector supplies power to consumers at 230 volts AC with a frequency of 50 Hz. In 2020 the electricity sector's grid supply came from 55% low-carbon power, 36.1% fossil fuelled power, and 8.4% imports. Renewable power is showing strong growth, while fossil fuel generator use in general and coal use in particular is shrinking, with historically dominant coal generators now mainly being run in winter due to pollution and costs, and contributed just 1.6% of the supply in 2020.
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.
Ireland is a net energy importer. Ireland's import dependency decreased to 85% in 2014. The cost of all energy imports to Ireland was approximately €5.7 billion, down from €6.5 billion (revised) in 2013 due mainly to falling oil and, to a lesser extent, gas import prices. Consumption of all fuels fell in 2014 with the exception of peat, renewables and non-renewable wastes.
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.
World energy supply and consumption refers to the global primary energy production, energy conversion and trade, and final consumption of energy. Energy can be used in various different forms, as processed fuels or electricity, or for various different purposes, like for transportation or electricity generation. Energy production and consumption are an important part of the economy. A serious problem concerning energy production and consumption is greenhouse gas emissions. Of about 50 billion tonnes worldwide annual total greenhouse gas emissions, 36 billion tonnes of carbon dioxide was emitted due to energy 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.
