What is the Minimum EROI that a Sustainable Society Must Have? Part 1: Surplus Energy and Biological Evolution

EROI theory is rooted in the biological principle that in order to survive each species on earth must procure more energy from its food than it expends attaining that food. From this basic principle the importance of energy surplus became evident, as food sources needed to “pay” not only for metabolism but also for reproduction and storage for leaner times. Part 1 of this three part series presents a brief history of the concept of surplus energy and how it has influenced both biological and human evolution.

Are “More Jobs” Sustainable or Necessary in the Post-Peak Oil World?

What was required for a growing economy, that was supposed to uplift all of modern humanity, is at root a false notion for the manipulated public: the overwhelming majority must work for others to enrich the few so that all of society benefits through unlimited expansion. This problematic profit-scheme is failing to hold up, what with general economic uncertainty on the rise (apart from “Hope”) and the advanced depletion of easily extracted, cheap oil.

How to provide relief to rural Americans, create jobs, and lower emissions … all at once!

Most homeowners in the U.S. would come out ahead if they invested in energy efficiency improvements — new insulation, sealed windows, more efficient boilers, and the like. So why don’t they do it? Simple: the upfront costs are steep and the paybacks can take a long time. Many homeowners don’t have access to the capital to cover the costs, or they worry that they will move before the the costs are repaid, thus leaving subsequent owners to reap gains they didn’t pay for.
