Your Friday Coal Question

I intend to spend some time this weekend with the 1865 classic by Jevons, The Coal Question. You can actually get yourself a free copy of this seminal work electronically in PDF form, from The Online Library of Liberty (see the link to Ebook PDF in the faint blue-block section). To kick off the weekend, I therefore present without comment two charts that measure global energy use by source on a BTU basis. Global Energy Use by Source 1998, and then the comparable chart using the latest available data, Global Energy Use by Source 2008.
