El Paso Electric, energy company headquartered in the city of El Paso in Texas, has gone carbon free. This the result of the decision taken by its top management to divest the company’s ownership share (7%) of the coal plant Four Corners, to provide the states of Texas and New Mexico exclusively with renewable energy. "This decision constitutes a tectonic shift across the southern United States, moving away from coal towards clean energy sources," said Antha N. Williams, head of Bloomberg Philanthropies environmental programs. Texas and New Mexico respectively produce 19% and 37% of energy from coal, but the plans of some energy companies, such as MidAmerican Energy in Iowa to get nearly 85 percent of its energy from renewable sources by 2020, and now that of El Paso Electric, could soon change these percentages. And they are good examples for other companies operating in the central and southern United States. Since 2010 some 238 coal plants have been closed down, which means more than 45 percent of all those active in Texas up to six years ago.
