Actually, the worst environmental factor of coal use is the process by which they extract it. Strip mining devastates areas. There are actually very very clean coal production plants in existence, the problem is there are very expensive. Coal is still by far the most dominating producer of electricity ( at least in the United States ), as it accounts for over 57%. The fact that there is so much demand and available resources, is why the price is so low.
