Q

Energy consumption in the UK

A

We use energy fundamentally. Without energy, there will be no heating, no lighting, no transportation or communication systems and very little industry. Over the last 40 years, the total energy consumption in the UK has fluctuated between approximately 140 000 and 170 000 of oil equivalent a year

Q

The changing energy mix in the UK

A

Energy mix is the range of energy sources used. The resources available to a country and decision about which sources to use will determine a country’s energy mix. In the UK, fossil fuels have been an important part of the energy mix because they are used in transport as well as in power stations to generate electricity.

Q

The electricity energy mix in the UK

A

In 1970, coal accounted for about 2/3 of all electricity generation. By 2012 this figure had fallen to under a half. The fall in use of coal was partly the result of a massive increase in the use of gas (AKA dash for gas) in the 1990s when gas from the north sea was cheaper than coal. Recent years have seen a gradual increase in the use of renewables. Renewable energy is seen more environmentally sustainable and efficient - converting fossil fuels into electricity wastes approximately 50% of the energy stored in primary fuel. It is expected that coal-fired power stations fitted with carbon capture and storage will start producing electricity by 2020, but increasing development of renewables will see then producing 40% of the UK electricity needs by 2030.
