Coal is very abundant and it is a cheap energy source. Cons. When coal is burnt it releases lots of carbon dioxide even more than oil and gas so it is the one of the worst contributors to global warming. When coal is burnt it also releases sulphur dioxide and nitrogen dioxide into the atmosphere which contributes to acid rain.
