One reason for high price of fossil fuel based power is that they are extremely in-efficient. Coal plants are about 30% efficient, Combined cycle plants about 40 - 45%. Compared to Solar and Wind, which have no input costs other than initial investment and very low maintenance and upkeep costs. And, the investment costs of setting up a 1 MW coal/gas plant vs. 1 MW solar plant, is about the same.
