Sadly, one of my favorite websites (and a website where I was previously a contributing author), www.theoildrum.com, is shutting down (actually converting to an archive, there will just be no new content). There are a variety of reasons for this, but in my opinion it doesn't reflect that energy has become any less central to questions about our civilization or its future.
A few articles I wrote for TOD in the past that are still worth considering (perhaps more so now than ever):
Oil Demand Destruction & Brittle Systems
Geopolitical Feedback Loops in Peak Oil
The Renewables Gap
Predator-Prey Dynamics in Demand Destruction and Oil Prices
Some weekend reading...
