Hmmm! I guess this supports your argument somewhat but not very strongly. As I said, everybody understands it takes energy to produce energy, whether coal fired, hydro power, solar or wind. The real question is which sources are most polluting + which redeem themselves over their functional lives for those initial energy inputs required to produce the specific infrastructure.

Coal is massively polluting + requires continuous extraction, where mountaintops are removed and transportation which has its own huge fossil energy inputs + associated pollution. Coal plants pollute over their entire operational lives. 

I notice you failed to rebut my point about the energy and pollution redemption produced by all forms of renewable energy, including wind. Your own La Farge link concludes with a paragraph on how wind redeems its "sins". Coal, of course, never does. Can you refute my point or will you deflect with more weak "support" of your own position?
