This is my first post for over a year, and I’m planning on following up with several more posts in the near future. I’ve been working on several projects, including my project engineering role in manufacturing, research projects on hydrogen and a book on...

EROI and theories of value Conventional economists’ rejection of EROI Conventional economists usually reject net-energy analysis. The assumption is that the price system embeds all the energy and non-energy costs, and therefore there is nothing to be gained by a...

A biophysical perspective of IPCC integrated models Analysis of the costs and benefits of climate mitigation involve extrapolation into the future. However, the long time horizons of interest extend well beyond the range of standard economic-development scenarios. In...

Understanding the divergence in EROI for solar PV Some analyses calculate an EROI for solar PV of 60:1 or higher, while some calculate a much lower EROI, in one recent case, less than 1:1. The casual observer could be forgiven for wondering what’s going on....

Renewables and reactive power A transition to higher penetration renewables is going to require much more attention to electricity networks. Most of the generator ancillary services have been essentially built into systems by virtue of using large synchronous...

The EROI of global food production Glaub and Hall have an interesting analysis of the EROI of hunter-gatherers. Despite humans being generally smaller, slower, and weaker than most large mammals, humans were successful hunters long before the invention of...
