Only a twit doesn't realize that any man made contrivance comes with energy and material inputs that result in initial pollution. Far more important is the pollution resulting or not resulting from that contrivances' usage over a long operating life. 

Both solar and wind require energy and materials to produce initially but then provide far more pollution free energy over their operating lives, more than mitigating any initial pollution. Coal and other fossil fuel driven power and transportation require polluting energy inputs and environment damaging extraction for their entire operating lives. They not only don't redeem themselves but often leave behind a legacy of inadequately reclaimed industrial zones and resultant air and water pollution
