In a finding that is likely to boost controversy over the future of U.S. energy policy, a comprehensive study of the full levelized cost of energy (LCOE) from various sources of electricity conducted by the University of Texas (UT) at Austin’s Energy Institute found that wind turbines and natural gas combined cycle power plants (CCPPs) provide the least expensive options for new generation across a large majority of U.S. counties.

The study, “New U.S. Power Costs: By County, with Environmental Externalities,” is part of an ongoing initiative at UT that attempts to take a “holistic approach” to calculating both direct and indirect costs of generating electricity.

The Institute has placed the results online in the form of an interactive tool that allows comparison of the LCOE for various options and adjustment of fuel costs. (The tool also makes some assumptions about the suitability of certain generation in various locations; for example, there are areas that would be unsuitable for fossil plants for environmental reasons.)…
