The World Coal Institute estimates that the earth’s coal reserves will last at least 120 years at the present rate of consumption. The abundance of coal makes it the cheapest form of energy for producing electricity. The other major reason that we depend so much on coal is because very powerful political interests from coal states have lobbied Congress for years to maintain a supportive environment for coal.
