Are you sure you don't? Depends on where you live I suppose...electricity is still made from coal in a lot of places...
We have hydroelectric and we also burn trash for electricity. I don't think we use coal around here, but I might be wrong. "They" were going to build a nuclear plant but it got scuttled by a bunch of flower-sniffing pansies.
We've got shitloads of natural gas too, so I would imagine if they were going to burn anything, it would be natural gas.
