localfuture.org Coal supply is limited by many factors, most importantly, by the energy return on energy invested. Coal supply is also limited by economic factors, such as the price of coal per ton, and this can limit the amount of mining that is economically feasible. In this compact 20-minute presentation, Leslie Glustrom addresses the myth of "hundreds of years of coal in the USA" by looking at both the economic and energy constraints.
Ms. Glustrom's talk was recorded at the 2009 Conference on Michigan's Future: Energy, Economy and Environment, organized by Local Future nonprofit and directed by Aaron Wissner. localfuture.org
