Scotland's electricity production is a topic of interest due to its high natural resource base for renewable energy, with wind, wave, and tidal power as the most important potential sources. In 2022, Scotland achieved a significant milestone by generating 113% of its overall electricity consumption from renewable sources, demonstrating the country's commitment to a green economy and net-zero targets. This has resulted from a combination of increased renewable energy production and decreased consumption of energy, particularly from fossil fuels. Scotland's primary sources of electricity generation include renewable energy, nuclear power, and fossil fuels, with a focus on wind power, hydropower, and tidal energy projects.

What You'll Learn
Scotland's renewable electricity capacity
The primary sources of electricity generation in Scotland are provided through renewable energy (61.8%), nuclear power (25.7%), and fossil fuels (10.9%). The most important potential sources of renewable energy are wind, wave, and tide. 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.
Onshore wind is the biggest single technology, accounting for 62% of installed capacity, increasing by 748 MW in the last 12 months. Offshore wind, hydro, and solar photovoltaics are Scotland's other major renewable power sources. Installed offshore capacity has increased rapidly over the last few years, with capacity increasing by 897 MW in the year. Wind-generated 78% of all renewable electricity output in Scotland, and hydropower contributed around 12%. While other technologies such as biomass and marine energy currently make a smaller contribution, they have massive potential for growth in the future. Solar generation is up 127 GWh in the last year, the biggest annual increase since the DESNZ Energy Trend records started in 2009.
Scotland has set ambitious targets for renewable energy production. In 2023, the target for 2030 was set at 11 GW of offshore wind power, representing a 400% increase in offshore wind and a 60% increase in total wind-generated power. Scotland also aims to produce 50% of all energy from renewable sources by 2030 and reduce emissions to net zero by 2045.

Nuclear energy
Scotland has a long history of nuclear research and electricity generation. Nuclear energy has consistently accounted for 20-80% of the country's electricity supply, depending on weather conditions for wind power generation and electricity demand. Between 2004 and 2021, nuclear energy accounted for 25-43% of Scotland's annual electricity generation. In 2022, nuclear energy made up 25.7% of Scotland's electricity production.
As of 2022, there is only one remaining operational nuclear power station in Scotland: Torness in East Lothian, owned by EDF Energy. It is scheduled to shut down in 2030.
The Scottish National Party (SNP) government elected in 2007 had a "no new nuclear power" strategy. This position is at odds with the UK government's policy, which announced the go-ahead for new nuclear power stations to be built across the United Kingdom in 2008. Scotland's then-First Minister Alex Salmond commented that there was "no chance" of new nuclear power stations being built in Scotland. The Scottish Parliament voted to support the policy of opposing new nuclear power stations, despite lacking authority over UK energy policy.
The Scottish government's opposition to new nuclear power has resulted in the planned closure of Torness in 2028, leaving Scotland without any nuclear power stations. This decision is part of Scotland's focus on renewable energy sources, with wind power being the fastest-growing renewable energy technology in the country.

Fossil fuels
Scotland has a long history of fossil fuel usage. Most of the largest oil fields in the UK sector of the North Sea were found in the waters north and east of the Scottish mainland, with Aberdeen becoming the centre of Britain's North Sea oil industry. The most recent figures from 2022 show that 11.4% of Scotland's electricity generation comes from oil and gas. This is a significant decrease from 2019, when oil and gas contributed 13% of Scotland's electricity generation.
In 2002, gas and oil made up 62% of Scotland's electricity generation. However, the country has since seen a significant increase in renewable energy sources, with wind power now comprising more than half of its electricity generation. Scotland's renewable electricity capacity has shown steady growth between 2009 and 2020, with an average annual capacity increase of over 700MW. In 2022, renewable capacity installed was up 1,621MW from 2021, the greatest increase in at least 15 years.
Scotland's primary renewable energy sources are onshore wind, hydropower, offshore wind, solar PV, and biomass. The country also has a successful waste-to-energy incineration plant in Shetland, which burns 22,000 tonnes of waste annually and provides district heating to over 600 customers. While this plant generates carbon emissions, it reduces the damage done to the atmosphere from the creation of methane in landfill sites.
Scotland has also made strides in reducing its consumption of fossil fuels. In 2020, 56% of the electricity consumed in Scotland came from renewable sources, with the country producing renewable electricity equivalent to its annual consumption. This has been driven by fears of fuel poverty and climate change, which have pushed the topic high up on the political agenda.

Scotland's electricity consumption
The Scottish Government has set ambitious targets for renewable energy. In 2019, renewable electricity generation exceeded 90% of Scotland's gross electricity consumption, and by 2020, the target was to meet 100% of gross consumption with renewables. In 2022, Scotland achieved a significant milestone by generating 113% of its overall electricity consumption from renewable sources, exceeding its consumption for the first time. This was largely due to the growth in wind power, which now comprises more than half of Scotland's electricity generation.
Scotland exports a significant portion of its renewable electricity to England and Northern Ireland. In 2023, Scotland exported approximately 35% of its total generated electricity, contributing to the electricity production of Great Britain as a whole.

Scotland's electricity exports
Scotland has a rich natural resource base for renewable energy, with wind, wave, and tidal power being the most important sources. In 2020, Scotland had 12 gigawatts (GW) of renewable electricity capacity, which accounted for about a quarter of the UK's total renewable generation. The country's renewable generation comes from onshore wind, hydropower, offshore wind, solar PV, and biomass, with onshore wind being the largest single technology.
Scotland exports a significant amount of its renewable electricity. On January 26, 2024, the Scottish Government announced that the country had generated 113% of its overall electricity consumption from renewable sources in 2022, a record-high figure. This milestone demonstrated Scotland's potential for a green economy and its progress toward net-zero emissions.
The development of renewable energy in Scotland has been a key focus for the country's government and political agenda. The Scottish National Party (SNP), elected in 2007, opposed the construction of new nuclear power stations and aimed to increase renewable energy production. The government set ambitious targets for renewable energy, aiming for 50% of all energy to come from renewable sources by 2030.
Scotland's renewable electricity capacity has shown steady growth, with an average annual capacity increase of over 700 MW since 2009. In 2022, renewable capacity installed increased by 1,621 MW compared to 2021, the greatest increase in at least 15 years. The total capacity now exceeds 15 GW, more than four times the size in 2008.
The growth in renewable electricity output has been significant, increasing from 8,003 GWh in 2007 to 32,063 GWh in 2020. In 2021, renewables were once again the largest contributor to electricity generation in Scotland, with wind power being the fastest-growing technology. Scotland's renewable energy sector supports over 42,000 jobs and contributes more than £10.1 billion to the economy.
