Donald … Do you know how much energy it takes to “clean” the coal? Clean coal is sum total more polluting.
The same with shale oil. It’s incomplete and you have to expend a great deal of energy to make it useful.
And before I get jumped on . . . Ethanol has the same problem. It’s an energy loser. It’s supported to help the “farmers.” In quotes because it really supports the corporate farming companies, not the family farmers
