Natural gas is the main fossil fuel used in the UK
The UK's energy consumption is high compared to the world average. In 2019, the country's total energy consumption was 142.0 million tonnes of oil equivalent. In the same year, the UK's energy consumption per capita was 2.78 tonnes of oil equivalent, compared to a world average of 1.92.
In 2022, the majority of the primary energy consumed within the UK (78.4%) came from fossil fuels, including coal, oil, and natural gas. Natural gas is a fossil fuel that is extracted from underground rock formations and burned to create energy. It is sometimes referred to as ""natural" gas by the industry to appear more environmentally friendly. However, it contributes to climate change and emits harmful greenhouse gases, such as carbon dioxide, when burned to generate electricity.
Natural gas is the most used fossil fuel in the UK. In 2022, natural gas and oil contributed 46.4% and 45.8%, respectively, to the country's total CO2 emissions from fuel combustion. In the same year, electricity generation accounted for around one-third of the UK's total fuel usage, and natural gas usage remained high. The UK also imports a significant amount of natural gas, with Norway being the greatest exporter of natural gas to the UK.
The UK has made commitments to reduce carbon dioxide emissions and increase the use of renewable energy sources. In 2020, renewable energy sources such as wind, solar, bioenergy, and hydroelectric power provided 43% of the UK's electricity.

Fossil fuel imports from Russia have decreased
The UK's energy mix is currently in transition, with a shift away from fossil fuels and towards renewable and low-carbon sources. In 2022, the majority of the UK's primary energy (78.4%) came from fossil fuels, including coal, oil, and natural gas. However, this represents a decrease from 87.2% in 2012, due to a decline in the use of coal, the dirtiest fossil fuel.
The UK has committed to achieving net-zero emissions across the economy by 2050, with a target for all electricity to be generated from "clean" sources by 2035. To meet these goals, the UK must reduce its reliance on fossil fuels and increase the use of renewable sources such as wind, solar, bioenergy, and hydroelectric power.
The reduction in Russian fossil fuel supplies has contributed to rising global energy prices and increased energy security concerns in importing countries. To address these challenges, the UK government has proposed building new gas-fired power stations to reduce reliance on imports. However, this decision has been criticized by the Green Alliance think tank as contradicting the commitment to reach zero-carbon electricity by 2035.
To further reduce fossil fuel imports from Russia and promote clean energy solutions, the Centre for Research on Energy and Clean Air (CREA) has suggested implementing tariffs on Russian imports and transitioning to clean, non-fossil energy sources, energy efficiency, and energy savings measures.
