If you have a efficient furnace it will burn natural gas and produce CO2 and water vapor as a waste product. What they want is for the power plant to burn natural gas, turn that gas into electricity, use that electricity to generate heat. For anyone who has ran a space heater you know that producing heat from electricity is very costly and wasteful.
I have a better idea, just ban Oregon altogether.
Not to mention that heat pumps heat with warm not hot air.
So you need to move a LOT of air.
These things would be bad for our trees. /s
