The nature of coal is such that the higher the carbon content, the more cleanly and brilliantly the coal burns. Thus ―peat‖, which is the state of the decomposing plants before being compressed, is a weak, impure substance. The other states of coal from lowest carbon content to highest are lignite, bituminous coal, and anthracite coal.

4.60, respectively, so coal has had more stable price variability than petroleum and natural gas. During 2011, coal is $2.40/MBTU, petroleum $20.11/MBTU, and natural gas $4.71/MBTU, so coal is clearly a more economically attractive fuel for producing electricity (gas may begin to look
