Nice presentation on EROEI...Summary
If the analysis presented here is applicable to the world's oil fields in
general, it can be expected that economic activity based on energy
produced from oil, will start to decline prior to Peak, and that it will
deteriorate after Peak at an accelerating rate!

How are you defining useful?

“Exact thoughts - the 1.089 is floating - why not have it off to the right and connect it with a line to the proper curve? “
“What is that number? Area under the curve? “
“Why is it useful? It seems to just clutter the graph without adding anything.”
“Total AE is measured in what? Barrels, on y-axis? “
Definitely consider a legend - the floating text, while presumptively corresponding to the line it breaks, is cluttering.
“If total AE is not measured in barrels, then why is it there? “
“If total AE is measured in barrels, then about the year 2000 it would appear that the graph is indicating that the total AE is close to zero. “
“What the hell does that mean? “
“Why say "per unit of crude". Why not just say what the unit is?”
“Why have two superimposed axes? Why not just put one on the right side of the graph, which is the convention? “
There is no differentiation between me using ten gallons of refined oil to move myself and and another a thousand miles and using ten gallons of gas to fuel a bonfire in my front yard because I want to.
Fortunately it won't go instantaneously from ten gallons to no gallons, and unless people enjoy paying exorbitant amounts, which they seem to some extent, users with certain exceptions, will likely increase the efficiency of use as prices increase after some point.shortonoil wrote:yesplease said:There is no differentiation between me using ten gallons of refined oil to move myself and and another a thousand miles and using ten gallons of gas to fuel a bonfire in my front yard because I want to.
The differentiation is that if the world’s oil fields follow the same path as the US fields have, you soon won’t have ten gallons of anything. What you do with ten gallons that you don’t have is irrelevant.

If it is the case that we can expect declining net energy from each future barrel of oil, then that may also impact negatively upon our ability to replace oil as a source of energy.
Very educational stuff there shortonoil. Can I ask if the dynamics for a gas field are the same, or does this only cover oil?
