Dolores,
Thanks for this post.You have incorporated many of the suggestions of the earlier post. It adds great value to see how the output varies with different input assunmptions.
I am not sure why renewable energy would decrease even in the low EROEI scenario for renewable enrgy? Would it not always increase?
The assumption of EROEI of 30:1 does not seem to be very high for present wind turbines.
What happens when it takes more than $10 in energy to extract $10 of oil?
Does oil become obsolete at that point or just more expensive?
I guess it is like the old gold mines where it costs more to get it out than it is worth......
Until the price goes much much higher....

My model doesn't deal with energy prices at all. It operates at a more basic level, it simply assumes that market forces will follow approximately EROEI, in other words, that something with high EROEI is going to be more profitable than something with low EROEI, and when EROEI approaches 1:1, you can't make business.
in the medium/long term you stop to make businnes when the ERoEI approaches about 10 not 1, I think there is a lack of understanding of the real meaning of ERoEI.
The reason usage of renewable energy eventually decreases in all the scenarios that collapse is because industrial output and food production are collapsing. Basically, people are too busy surviving to cope with maintaining their renewable energy infrastructure.
Which is another assumption of the model, its not shown by it. Sheesh.
