Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Confusion about EROI might have the same source: special interests. The "energetic" inertia as well.

Counting EROI as a fraction of the Net Energy Yield is like counting debt as a fraction of GDP. Both fractions look great when the denominator is large. But then oops happens...

... we could have access to almost limitless amounts of carbon-free electricity if we felt like it.

... we are absolutely dependent on a process with an EROI of 0.3-0.4, namely the combustion of fuels to make electricity. I don't think anyone argues we should stop that, despite the low EROI...

So are we free to do what we "feel like it", or are we "absolutely dependent"?

Any process with EROI < 1 is a part of metabolism, not the input. The question is: can we grow when the input starts to stagnate or decrease?
