There is an abundant supply of coal in the UK. Coal is a non-renewable fossil fuel consisting of the compressed remains of ancient swamp forests. As such, coal is found under sedimentary rock.
Unfortunately, burning coal produces huge amounts of the greenhouse gas, carbon dioxide (CO2). This is a major contributor to global warming.
The other gases produced are also a major contributor to acid rain. There is even evidence that the smoke contributes to something known as global dimming, whereby less sunlight reaches the ground, so cooling the earth.
This has alarmed many people as it may be hiding the true effects of global warming.
