Non-renewable energy

Coal is a fossil fuel formed in ecosystems where plant remains were preserved by water and mud. Coal is primarily used as a solid fuel to produce electricity and heat through combustion. When coal is used for electricity generation, it is usually pulverized and then burned in a furnace with a boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines which turn generators and create electricity.

It is relatively cheap to convert into energy and supplies will last longer than oil or gas.

Burning coal releases greenhouse gases such as carbon dioxide. It also causes acid rain.

Oil is a carbon based liquid found under ground in large reservoirs. It is formed from fossilised plants and animals. Humans drill for oil which is then pumped to the surface. It is processed for use by industry and transport.

It is relatively cheap to extract and convert into energy.

It is finite, when burnt it releases greenhouse gases.

Natural Gas
Methane gas is trapped between seams of rock below the surface of the earth.

Cheap to extract and cleaner than oil and coal.

It is finite, when burnt it releases greenhouse gases.

Nuclear energy involves extracting radioactive minerals such as uranium. The atoms of these minerals are split or joined together. Electricity is generated from the energy created by this.

Only a small amount of radioactive material is required, there are no atmospheric pollutants and raw materials are relatively cheap,

It is expensive to produce, the waste is highly toxic and needs to be stored for 100s even 1000s of years and accidental leakage can cause massive environmental problems.
