Nate Hagens on Energy, Resources and Human Demand on a Full Planet

Part 2 Part 3 Part 4 Part 5 Part 6

Nate Hagens is an ex vice president of Lehman Brothers who voluntarily left his business career some years ago out of concerns about 'negative externalities'. Now he is doing his PhD at the University of Vermont Gund Institute for ecological economics, establishing connections in his research between the limits to growth and different possible responses, both in terms of alternative energy sources and change in consumption behaviour. I don't always like his reductionist take on questions of behaviour and ideology, explaining patterns of behaviour in terms of biochemical brain functions, but he has a lot to say about the predicament of the limits to growth.

His university page introduces Nate Hagens in these terms:

Nate is studying the impacts that a decline in liquid fuels will have on planetary ecosystems and society. On the supply side, he is exploring net-energy comparisons of the primary alternate fuel sources to oil: coal, wind, nuclear and biomass. While many new energy schemes will produce profits from a bottoms-up perspective, an EROI (Energy Returned on Energy Invested) analysis from a top-down perspective limits the scope of energetically and ecologically sound replacements for fossil fuels.

Because of this, real progress on the human and planetary scale issue will likely come from a reduction in consumption. On the demand level, Nate is studying the evolutionary mechanisms that cause humans to seek novelty, act impulsively, and value the present over the future (steep discount rates). Specifically, our neural plasticity combined with a culture promoting growth and consumption results in biochemical positive feedback loops akin to addiction. We can however, be happier, healthier and more sustainable by consuming less, if we are provided with a different cultural carrot. Nate’s thesis lies in modeling sustainable scale solutions to the future decline in EROI by researching ways to reduce the steepness of our discount rates, thus giving more weight to the planet’s future.
