I have found Gail Tverberg to be a most excellent source of analysis and data on this topic: https://ourfiniteworld.com/
The author of Our Finite World is Gail Tverberg. She is a researcher focused on figuring out how energy limits and the economy are really interconnected, and what this means for our future. Her background is as a casualty actuary, working in insurance forecasting.
Gail first became aware of oil shortages, and the impact they could have on insurance companies, back in the 1973 – 1974 period, when oil limits were first a problem. In 2005, she began reading books on the subject, including Jeremy Leggett’s The Empty Tank. Gail did further research about the situation, and wrote her first article about the potential impact on the property-casualty insurance industry in early 2006.
In March 2007, Gail decided to research the issue of limits of a finite world on a full-time basis, leaving her career in insurance consulting. She began OurFiniteWorld.com in 2007, but temporarily changed her writing base to TheOilDrum.com between mid-2007 and 2010, where she was a writer and editor. Since late 2010, her blog posts have been published on OurFiniteWorld.com.
