Coal is a hard and black.

How it works

When coal generates electricity, it has to be brunt first, 
after that coal produces heat, which heats the water, 
and the water turns to steam, and produces energy.

How does it affect the environment?

Mining coal releases dust and gas into the air, burning coal will pollute the air.

Will it last forever? (is it renewable or non-renewable)

Coal is non-renewable, because when you use it all its gone and there is not going to be anymore.


Coal can be found in lots of places in the world.
Coal can be easily transported to the power station.
Coal is quite cheap energy soruce.


To dig up coal, we have to create mines which can be dangerous and not nice to look at.
Transporting coal by lorry or train causes pollution.
Of all energy sources burning coal releases the most greenhouse gases which may add to global warming.
Coal is non-renewable and will not run out in about 100 years.
Coal miners can be affected by black lung disease or pneumoconiosis and also emphysema if
they breathe in too much of the coal dust
