Coal is our most abundant, cheapest, and found right here within our own wonderful country, to supply us with all the power we need to power our automobiles and anything else. U.S powerplant technology surpasses Aussie tech, so dont chime in(Such as Cogen plants, with limerock). Funny thing is, you have all these enviromental freaks who are worried about pollution and climate etc.., so they dont want to use it, sooo they would rather load it on a boat and ship it to China, who have no problem with burning it without any of our scrubbing filter technology installed on their plants, but people dont speak out about that,if they do they disappear, with most of their family. Meanwhile we attempt to conserve energy when we are sitting on litterly, tons of it, to save the planet for our children. Meanwhile throw another tire on the fire in Mexico. Why cant we all just worry about now, yes, some day the Earth will end, someday the sun may burn out, the super Volcano may erupt and plummel 2/3rds of the U.S, its gonna happen on somebodies generation. But until the Earth is all one big country, lets just use the coal ourselves and be done with it.
