Maybe TJ's scenario will be postponed for a decade or two or three :) Maybe, but I'd like to know more about the EROI (energy return on investment) for the shale abracadabra. Got this link from Wharf Rat... How Fish Use Energy Teaches True Oil Economics ENERGY & EQUITY, a Tyee column by Andrew Nikiforuk, this week explains the secret of EROI. thetyee.ca After his fish energy studies Hall, a student of the great ecologist Howard Odum, started thinking about energy gains in the oil patch in the early 1980s. He wondered if the industry experienced that same sort of declining returns over time that dogged the world's fisheries. As ships, nets and quantity of oil burned got larger, the protein returns per unit of energy invested shrank dramatically. Cutler Cleveland, then a muscular undergraduate and now an energy brain in his own right, investigated and came up with a puzzling graph. It was N shaped and showed energy gains for oil going up and down like a yo-yo. "The yield per foot of drilling would reach a minimum and then jump back up, then down even more sharply." Hall then asked Cleveland to add the number of feet drilled per year and then the graph showed a dramatic decline over time. "It was just like the fisheries."
