If we include the coal externalities, it increases the levalized costs to approximately 28 cents per kWh, which is more than hydroelectric, wind (onshore and offshore), geothermal, biomass, nuclear, natural gas, solar photovoltaic, and on par with solar thermal (whose costs are falling rapidly). Suddenly coal doesn't look like such a good deal.

In 2010, a detailed economic analysis of the costs of downwind pollution (primarily from coal plants) concluded that each dollar spent on airborne pollution controls saved 50100 in annual costs downwind. Another study, released in Feburary 2011, estimated that the true cost of coal was up to 500 billion annually in the United States alone. This study further calculated that if all the externalized costs of .
The United States Department of Energy's Office of Fossil Energy, through the Gasification Systems Program, is developing innovative and flexible modular designs for converting diverse types of US domestic coal into clean synthesis gas to enable the lowcost production of electricity, highvalue chemicals, hydrogen, transportation fuels, and other useful products to suit market needs.
In 2008, Synapse found that the estimated costs of building new coal plants had reached 3,500 per kW not including financing costs, and that costs were still expected to increase further. These cost increases were driven by a worldwide competition for power plant design and construction resources, commodities, equipment, and manufacturing capacity.
