For millions of years, a layer of dead Coal is a black or brownish-black rock plants at the bottom of the swamps was composed mostly of carbon and covered by layers of water and dirt, hydrocarbons. It is the most abundant fossil trapping the energy of the dead plants. fuel. The heat and pressure from the top layers helped the plant remains turn into what we today call coal. Coal is a non-renewable energy source because it takes millions of years to create. The energy in coal comes from the energy stored by plants that lived hundreds of millions of years ago, when the Earth was partly covered with swampy forests.

This is coal

• Very large amounts of electricity can be generated in one place using coal, fairly cheaply. • Transporting oil and gas to the power stations is easy • Gas-fired power stations are very efficient

• Basically, the main drawback of fossil fuels is pollution. Burning any fossil fuel produces carbon dioxide, which some people believe contributes to the "greenhouse effect", warming the Earth. • mining coal is difficult and very dangerous

This is a very dangerous coal mine
