Book review of Failing states, collapsing systems biophysical triggers of political violence by Nafeez Ahmed

Posted on January 31, 2017 by

[ 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?

Posted on May 15, 2016 by

[ 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 →

David Fridley, LBNL scientist, on why alternative energy won’t save us

Posted on March 10, 2014 by

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

Posted on March 5, 2014 by

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 →
