During the later years of the first revolution, as steam power really took a firm grip, thisPrices have fluctuated since then, but gas has continued to be plentiful and cheap. This has had two effects on coal. One is that cheap gas displaces coal in existing power systems. Secondly, cheap gas increases the incentives to finally retire old coal-fired plants from the 1940s and 1950s.
