Clean coal still pollutes, move to renewable fuelsI sat reading “Future energy needs still depend on coal” published June 27 and my jaw just about hit the floor. How could the Bemidji Pioneer publish this in the same month that Popular Mechanics, Popular Science and Scientific America all published articles debunking these myths. The scientific reality is that “clean coal” is impossible. You cannot clean coal, you can transfer the problem from one medium to another but it is still pollution. It does not matter if it is air, water, or ground, it still contaminates.
