even though there is talk about "green" energy sources like windmills, nuclear power, clean coal technology, i don't think coal will be eliminated as an energy source, at least not any time soon. to get to the point where we're using windmills, etc. as enrgy and not coal, alot of money needs to be spent. with the economy how it is, i doubt it will happen soon.
from my understanding, coal is still in demand. in my area, 2 new deep mines are going to open within the next 3-5 years and i know that excavating for the shaft has already begun on one. they're supposed to be used to mine a deeper seem of coal that as far as i know has yet to ever be mined. i also understand that a lot of coal is exported to countries over sea to fire the coal fired power plants and also for steel production.
