I work in the oilfields and have family who work in the coal mines. A sensible approach would be to first jerk really hard on the EPA's chain and bring them to heel. Then use both natural gas and coal together to fire the plants. There is a cutthroat mentality between the oil and coal industries that needs to go away. All of us that want to see this country achieve energy independence need to come together if we are to survive the onslaught from idiots that have no real understanding or common sense and that are in our government and schools pushing the "no more CO2" agenda.
