Natural gas cheapest electricity source (including externalities) in graphs-of-the-year collection at @ezrakleim @bradplumer. Michael Greenstone of MIT offered this one, saying: 
“By unlocking vast new resources of natural gas in the U.S., fracking has transformed the energy landscape and dramatically reduced the price of natural gas. This graph summarizes the three types of costs associated with various sources of electricity generation: (1) the private costs of production; (2) external costs due to the release of conventional pollutants (primarily increased rates of morbidity and mortality); and (3) the external costs associated with the release of carbon dioxide and the resulting increase in climate change. When all three of these costs are considered, natural gas is the least expensive source of electricity.”
