Electricity generation is not going back to coal.  Most of the electricity generating plants in the US have been converted to operate on natural gas, and those that haven't are in the conversion process.  There is no economic reason, and plenty of environmental reasons not to reverse that. But jurisdictions that make themselves noncompetitive through mismanagement and inept policies, and compound that by repeating the same or similar misdeeds over and over, have a questionable future ahead of them.
