Energy Mix in the UK

The UK is increasing its use of renewable energy (particularly solar and wind) and cutting down on fossil fuels.

Wind energy

  • Wind energy is projected to provide 25% of the UK’s energy by 2020.
  • By August 2018, there were 8,911 wind turbines in the UK.
  • They are located in areas with good wind speed, often on top of hills or just offshore.
  • 60% of the UK's energy from wind is produced in Scotland.
  • It is currently supported by government subsidies to ensure expanded use.

Solar energy

  • Solar power energy has increased by 86% between 2014 and 2015.
  • The largest solar farm in the UK is at Shotwick.
  • It is currently supported by government subsidies to ensure expanded use.

Nuclear energy

  • A new generation of nuclear power stations is being established.
    • E.g. Hinkley Point C will provide the UK with 7% of its energy needs.
  • Nuclear power is controversial in the public eye because it would pose risks to human health if there were a leakage or explosion.

Radical Technologies

Radical technologies are newer alternative approaches for a more sustainable future in terms of fuel and carbon emissions.

Carbon Capture and Storage (CCS)

  • Carbon dioxide is captured from emissions from coal or gas-fired power plants.
  • It is then compressed and transported by pipeline and injected (in liquid form) into underground reserves, such as depleted gas fields.
  • The CO2 solution turns basalt into white chalky calcites that fills the rock’s pores.
  • In theory, this method could reduce carbon emission by 19%, but it is currently quite expensive and controversial.
  • There are currently 16 operating plants in the world.

Hydrogen fuel cells

  • When hydrogen is separated from other elements by electricity, it produces hydrogen by itself which you can burn.
  • This hydrogen can be used as an alternative to oil and is more energy efficient in vehicles.

Electric vehicles

  • Problems with electric cars included their price and limited distance range between charges (100-150 miles).
  • But the newest electric cars by Tesla can extend over 200 miles and are cheaper, though still around £25,000.
