It's kind of a counterpoint still. We tried and managed to replace coal for home heating and transport with something else, because coal kind of sucks for those things. The fact that coal continued to be used in new ways is a consequence of coal dropping in price and there being no real external pressure to eliminate coal usage. It's not clear what happens once there's strong pressure to eliminate these fuels from our economy, because we've never really tried it before.
