CFE's Responsibility Behind Coal Exploitation . About 4 percent of Mexico's electricity is produced with coal, according to data published by the state utility in 2021. Despite its limited use, this small percentage of power production is one of the reasons behind tragedies, deaths and the precariousness of miners in the Coahuila coal region.
