Net Energy Cliff Will Lead to Collapse of Civilization
The remaining oil is poor quality, and the energy to get this often remote oil so great that more and more energy (blue) goes into oil production itself, leaving far less — the grey area — available to fuel the … Continue reading
Transportation: How long can we adapt before we fall off the Net Energy Cliff?
[ I first published this in 2014. After re-reading it when damnthematrix republished it recently, I saw corrections and updates that needed to be made, so here is the improved version. Keep in mind that I am wildly speculating, there … Continue reading
Gail Tverberg: 2017 The year the world economy starts coming apart
[ Note: In a 2016 post “Overly Simple Energy-Economy Models Give Misleading Answers” Tverberg points out that: “The common lay interpretation of simple models is that running out of energy supplies can be expected to be our overwhelming problem in … Continue reading

Book review of Failing states, collapsing systems biophysical triggers of political violence by Nafeez Ahmed
[ In this post I summarize the sections of Nafeez’s book about the biophysical factors that bring nations down (i.e. climate change drought & water scarcity, declining revenues after peak oil, etc.) The Media tend to focus exclusively on economic … Continue reading

How much net energy return is needed to prevent collapse?
[ Charles Hall, one of the founders of EROI methodology, initially thought an EROI of 3 was enough to run modern civilization, which is like investing $1 and getting $3 back. But after decades of research, Hall concluded an EROI … Continue reading

Conservation? Maybe not: Jevon’s Paradox & the Rebound Effect
Conservation? Maybe not: Jevon’s Paradox & the Rebound Effect by Alice Friedemann, October 7, 2014 The rebound effect makes it much more difficult to solve our energy problems, because the full energy savings aren’t realized, and the energy savings can … Continue reading

David Fridley, LBNL scientist, on why alternative energy won’t save us
My summary of LBNL scientist David Fridley’s 9-page Alternative Energy Challenges. The showstopper is that the entire supply chain for alternative energy resources depend on fossil fuels, from mining basic (rare) metal ores, to fabrication, delivery, maintenance, and spare parts. … Continue reading

A financial crash would stop new oil production, sending us over the net energy cliff with a 10% decline rate per year
Gail Tverberg’s March 4, 2014 “Reasons for our Energy Predicament – an overview” gave me this sudden insight: There is the potential for a sudden drop of 10 to 30% in oil production. That magnitude of world-wide oil shocks would … Continue reading
