Combined-cycle gas turbines have become the greatest contributor to the British power mix. Between September 2019 and September 2020, they accounted for up to one third of total electricity generation. Meanwhile, coal's importance to the energy sector has reached a historic low. In the summer of 2020, no coal energy was fed into the British power grid for the first time since the Industrial Revolution. Coal's importane to the UK power supply has declined rapidly since 2015, following the government's efforts of reaching carbon neutrality by 2050.

In 2021, low-carbon energy sources accounted for almost 60 percent of the electricity generated in the United Kingdom, while gas was responsible for 40 percent of the electricity production of the country and coal for a mere two percent share. Electricity from coal made up the largest share of the UK's electricity mix until the end of the 1990s, when gas took over. Low-carbon electricity sources started to grow in the 2010s and went from a 20 percent share to 62 percent of the country's electricity mix in 2020. In 2021, wind and solar energy sources accounted for roughly 25 percent of the power supply of the country, while nuclear energy supplied another 15 percent of the electricity mix.

Coal is being steadily phased out of the United Kingdom's electricity supply mix. In 2010, coal power amounted to ***** terawatt-hours. A decade later, less than ** terawatt-hours were annually produced from coal. Meanwhile, in 2023, renewable sources were the main fuel used for electricity in the UK, with ***** terawatt-hours generated. The second-highest fuel type that year was gas, generating ***** terawatt-hours worth of electricity.

Octopus Energy is most reliant on anaerobic digestion, which accounted for ** percent of the fuel mix composition in 2018. As of 2020, wind energy made up the greatest portion of the utility company's investment portfolio. Octopus Energy's turnover reached nearly *** million British pounds in 2019.

The volume of coal produced in the United Kingdom has fallen considerably since 1970. In that year, 136.6 million metric tons was produced from deep mining alone, but by 2017 UK production volumes had fallen to a record low of 20 metric tons. Surface mining overtook deep mining as the most productive coal mining type in the UK by 2005. In 2022, some 588,000 tons of coal were retrieved through surface mining.Death of an industry As production has decreased, so have the number of operational coal mines in the UK. In 2000, deep mine numbers stood at 33, but 21 years later this number had fallen to just four. This in turn has affected UK coal mining employment numbers. Historically the coal industry has been a major powerhouse of the UK’s economy, employing more than one million individuals in 1920. By 2021 the number of employees was less than 500, showing a shift away from the fossil fuel. Coal in the energy mixThe reliance on coal in the UK’s energy mix has plummeted. In 2020, only 5.5 terawatt hours of electricity were generated using coal-fired power stations, accounting for 1.8 percent of all electricity generated that year. In May 2019, Britain went one week without coal power, the first time this had happened since 1882.

Monthly power sector emissions in Great Britain are typically highest in the colder months, and during this period reached a high of 10.53 million metric tons of carbon dioxide equivalent in January 2017. Since then, monthly emissions have been in a downward trend. This is mainly due to the reduction of monthly emissions released from coal combustion. Whilst historically a major consumer of coal, this energy source is being phased out in Great Britain and replaced with cleaner energy sources such as renewables, nuclear, and natural gas. Presently, coal accounts for just two percent of the UK power mix. In comparison, CCGT makes up for more than 40 percent.

Bioenergy electricity generation has recorded mixed performance in recent years amid rising environmental opposition and a shifting policy landscape. Despite being classified as a renewable energy source, bioenergy has faced criticism for its carbon emissions, which often exceed those of fossil fuels. Strong government support and converting major coal-generating units to biomass plants fostered strong growth before 2018. However, new bioenergy projects have since struggled to gain traction, hampered by intensified opposition from environmentalists and a pivot in renewables strategies towards offshore wind. Revenue is forecast to dip at a compound annual rate of 0.6% to £2.5 billion over the five years through 2024-25. Growth in bioenergy electricity generation volumes started slowing down in 2020-21 before declining over the two years through 2023-24. Revenue has followed a slightly different trajectory, with soaring wholesale electricity prices contributing to a surge in revenue among bioenergy electricity generators that aren’t subject to fixed prices. Contracts for Difference (CfD)-backed biomass plants struggled during this period, with the generation of electricity sold at fixed rendered temporarily uneconomical when feedstock prices peaked. Revenue is set to grow by 12.1% in 2024-25, aided by a new 299-megawatt biomass plant in Teesside, which began generating electricity under a CfD in September 2023. Revenue is slated to climb at a compound annual rate of 3.2% over the five years through 2029-30, reaching £2.9 billion. The integration of Carbon Capture and Storage (CCS) technology will be vital to addressing environmental criticisms and securing bioenergy's role in the UK's renewable energy mix. The government’s plan to create a competitive market for CCS by 2035 signals a supportive stance, evidenced by recent approvals for Drax to convert biomass units to Bioenergy with Carbon Capture and Storage (BECCS). However, the exact nature of future subsidies remains uncertain.

Coal has been a major industry in the United Kingdom since the start of the industrial revolution in the 18th century, with production estimates in 1750 at five million metric tons. In 1913, UK coal production peaked at 292 million metric tons. By 1920, the coal industry employed some 1.2 million people, which was approximately 1-in-20 of the UK's workforce. Production has dropped massively since it's golden age, falling to just one million metric tons in 2023. In 2020, the UK government announced that coal would be phased out of the nation's energy mix by the end of 2024.

The United Kingdom’s electricity use has been declining since peaking at *** terawatt-hours in 2005. In 2024, the UK's electricity increased on the previous year, amounting to *** terawatt-hours. Electricity consumption in the UK typically follows a seasonal trend, peaking in the winter months. How electricity-intensive is the UK? Despite the continual decline in electricity consumption, the UK remains one of the largest electricity consumers in the world. In terms of per capita electricity consumption, however, the UK ranks low in comparison to other European countries such as Norway, Germany, and France. In 2023, it registered an average of ***** kilowatt-hours per person. The race towards a clean power mix In 2010, gas and coal accounted for roughly ** percent of the UK's power mix. Since then, alongside the EU Renewables Directive, the UK agreed and created its own National Renewable Energy Plan, to increase the use of renewable sources and decrease its fossil fuel dependence. In the past decade, the share of energy consumption in the UK attributable to renewable energy increased slightly, although it was still a small percentage out of the total in 2023.

The United Kingdom generated 82.3 terawatt hours worth of electricity and heat through wind power in 2023. Onshore wind farms produced 32.6 terawatt hours of power, which was less than the amount generated by farms situated offshore. Wind power capacities have steadily increased in the past year, with renewable energies taking up a greater share of the UK's energy mix, following the phase-out of coal.

Global electricity generation has increased significantly over the past three decades, rising from less than 12,000 terawatt-hours in 1990 to almost 30,000 terawatt-hours in 2023. During this period, electricity generation worldwide only registered an annual decline twice: in 2009, following the global financial crisis, and in 2020, amid the coronavirus pandemic. Sources of electricity generation The share of global electricity generated from clean energy sources –including renewables and nuclear power- amounted to almost 40 percent in 2023, up from approximately 32 percent at the beginning of the decade. Despite this growth, fossil fuels are still the main source of electricity generation worldwide. In 2023, almost 60 percent of the electricity was produced by coal and natural gas-fired plants. Regional differences Water, wind, and sun contribute to making Latin America and the Caribbean the region with the largest share of renewable electricity generated in the world. By comparison, several European countries rely on nuclear energy. However, the main electricity sources in the United States and China, the leading economic powers of the world, are respectively natural gas and coal.

The United Kingdom's reliance on fossil fuels to generate electricity decreased over the years, in particular regarding coal. In 2023, the country used 900 thousand metric tons of oil equivalent worth of coal, compared to almost 29 million tons two decades earlier. That year, gas was the main fuel used, with some 18 million tons of oil equivalent.
