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....

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...
