The Oil Drum

Introduction

I can be a very persistent (some might say hard-headed) person. If someone doesn't understand something that I think is important - and readily understandable - I will often continue to explain it until I am sure they either understand it and won't admit it, or they are incapable of understanding it. Because the topic of EROEI continues to be misunderstood (especially by those in the camp of "the only thing that matters is economics"), I will once again try.

Nate Hagens and I have discussed this subject at length on a number of occasions. He has written extensively on it, and I don't pretend that this essay can hold a candle to his magnum opus - and in my opinion best ever EROEI essay written at TOD - A Net Energy Parable - Why is EROI Important? (There's your dopamine fix for today, Nate.) This is just a little review of why I think EROEI matters.
