I must confess I was wary of delving into Collapse: How Societies Choose to Fail or Succeed by Jared Diamond, as I was never able to plow through to the end of Guns, Germs, and Steel.
I'm glad I worked through this one though, even if it was a few years after publication, as Mr. Diamond has added to my world view of environmental issues beyond my extensive reading about climate change.
Here, for both ancient societies and our current global community, he describes how societies have failed to manage natural resources to such an extent that they completely fail.
I highly recommend the work, though I would steer people to read the Prologue, maybe just the section on Easter Island in Part Two, the chapters on China and Australia in Part Three, and all of Part Four, where he discusses practical lessons that can be applied based on the analyses of each collapsed or collapsing society.
There is no explicit discussion of energy resources in the book (though it does come up in the discussion of China and Australia), but it isn't at all difficult to apply the thinking around resource depletion to the energy sector.
In summary, a challenging read in terms of scholarly tone and sobering conclusions, but worth the high praise it has received.
