Coal is found in nature too. The abundance of combustible material in coal is what makes it an important domestic fuel resource. However, the use of this fossil fuel has led to negative effects on the environment. Electricity from coal is called thermal power. The coal was formed millions of years ago when giant ferns

Energy sources which we can use to power our homes and to transport us from one place to another. These include coal, oil and natural gas.

Most of the oil found in the crust of the Earth were also formed millions of years ago, but some very small amount were formed only a
