Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

If the EROI is that low, it's a good indication that it is very bad business for the economy as a whole, because you are being paid to destroy energy

A power plant is a business operation which is paid to destroy energy. So is a refinery. Should we ban power plants and refineries and consider them examples of things which are very bad for the economy, when they are actually the very opposite of that? These are the kind of  strange conclusions you get from EROI theory.

Peak oil is not an energy crisis. It is a liquid fuel crisis.

There are plenty of questions EROI doesn't tell you anything useful about. But unless you assume the problem of energy scarcity away EROI will not be entirely useless. Certainly less arbitrary than market prices.
It doesn't matter that we wouldn't have energy scarcity for quite a while if we had started a sensible investment program in time.

Well, I do not worry that much about energy scarcity. While oil is an immensely large and important source of energy, its crucial job is as an energy carrier for the transportation sector. In other words, see my signature.

Yes, the energy crisis is that the energy sources that we have built our industrial society on turn out to be a climate suicide pact.

It would, however, be taking on a foolish technology risk to build a system that is immune to the coming liquid fuel crisis in our transportation system that would in turn have to be shut down if opponents of Climate Kamikazes get the upper hand, when established and effective technologies that opponents of Climate Kamikazes would be fine with are at hand.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.

They would be the strange answers you would get from EROI if you decided to use it as a business tool for making energy production plant investment decisions.

But as nobody proposes doing that, it seems rather a moot  point.
