Facts and figures on the UK energy supply

The UK energy supply benefits from highly diverse and flexible sources of electricity, with the energy mix constantly changing. Although the region is transitioning to a low carbon system, coal remains an important source of energy.

What influences UK energy supply and demand?

  • Energy efficiency
  • Weather
  • Economic activity
  • Consumer activity

Why do average electricity generation sources vary from day to day and year to year?

  • The cost of gas and coal
  • Environmental policies
  • Availability of renewable energy
  • Energy prices of other interconnected countries

UK Energy Supply: 80% reduction in emissions by 2050

The UK has made it clear that it wants to reduce its dependence on oil and gas. The goal is to reduce emissions by 80% by 2050.

How are we doing?

Half of the energy generated from ‘homegrown’ fuels (including fossil fuels like coal and gas) now comes from renewable sources.

This is up from less than a third in 2013.

In 2018, wind and solar power overtook power produced by nuclear power plants.

55 hours of coal-free electricity

55 – The length of time the UK was powered without using coal in April 2018. This is the longest time the nation has been powered for so long without using coal since the world’s first coal-fired power station for public use was opened in London in 1882.

The amount of electricity generated using zero or low-carbon energy is over 60% . This is comprised of: 

Low Carbon Source% of total
Nuclear 20.1%20.1
Wind 33.7%33.7
Solar 3.3%3.3
Biomass 5%5
Hydro 0.9%0.9

The UK’s Energy Timeline

Late 1990s:

  • Nuclear power plants contributed around 25% of total annual electricity generation in the UK.


  • World’s ninth-largest consumer of energy.


  • 13th-largest producer of natural gas in the world.
  • Largest producer of natural gas in the EU.


  • UK had around 3.1 billion barrels of proven crude oil reserves (the largest of any EU member state).


  • UK produced 914 thousand barrels per day (bbl/d) of oil and consumed 1,507 thousand bbl/d.
  • Renewable electricity sources provided 14.9% of electricity,


  • Wind power generated 9.3% of the UK’s total electricity.


  • Wind power generates 14 gigawatts of electricity for the first time – nearly 37% of the country’s needs.
  • The UK goes more than two days without using any coal-fired power for the first time in more than a century.
