Changing market conditions have made natural gas, wind and solar energy the lowest-cost technologies for new electricity generation for most of the U.S., according to updated research released today by The University of Texas at Austin’s Energy Institute. The research features a series of maps that have been revised to reflect shifting market conditions, a new policy environment and other factors affecting the cost of electricity generation in counties across the U.S. The updated version also displays the same data for congressional districts…researchers analyzed data for the most competitive sources of new electricity generation. Wind again proved to be the option with the lowest cost, on a levelized basis, for a broad swath of the country, from the High Plains, the Midwest and Texas, and even portions of the Northeast. Solar power is the cheapest technology in much of the Southwest, and, based on updated data, also in the eastern and northern regions of the U.S. Natural gas prevailed for much of the rest of the country.
