Modern Thermal power plants reached Thermal efficenies of 45-50% for coal and closed cycle gas turbines. ICE cars have a hard time reaching 25% under normal conditions. Additionally burning methane has lower CO2 emissions than gasoline and a third of the US grid is produced from carbon free sources anyway.
