David Rutledge: Worldwide coal resources may not be as extensive as people thought.

You’re listening to CalTech engineer David Rutledge, who spoke to EarthSky at a recent science meeting. He said governments around the world have [---1---] coal reserves, the amount of coal still available for energy use.

David Rutledge: That estimate at all, at least for these trends, appears to be high, for coal.

To figure out how high, Rutledge studied trends in countries that have already [---2---] coal.

David Rutledge: I have a librarian who's spent a year collecting the production numbers for all the coal-producing countries of the world back to about 1800.

Rutledge’s study suggests that [---3---] coal production – total production for past and future mining – is only 60 percent of what governments around the world estimate. In other words, no matter what you may think of coal as an energy source, the fact is we may have less to [---4---] than previously believed.

Dave Rutledge: It would be good news for climate change. [---5---]

Rutledge added his estimate provides a good reason to develop and transition to alternative fuels.

Dave Rutledge: You want to get cracking, independent of climate consideration.

It was David Rutledge, and I'm Deborah Byrd for Earth & Sky, a clear voice for science. We are at E&S.org
