Electric pricing depends largely on fuel costs. Coal is and will continue to be the least expensive fuel for generating electricity. Unlike other fossil fuels used for generating electricity, coal prices have changed little since the 1980s. In 20 years, the price of coal has increased only four percent, while crude oil prices increased 51% and natural gas prices increased 211%.
