I thought it would be helpful to repost a comment made in August by Dr. Doom in the "Savinar Debunked" thread that Matt Savinar started. He gives several examples of how statistics are tricky and generally makes one of my points very articulately.
"Matt, I also want to thank you because it was through your site that I discovered the PO phenomenon.
That said, I do think your detractor makes some good points, they are points that I myself have come to believe are flaws in the doomsday argument.
Specifically, I think it is demonstrably untrue that conservation won't work. As your detractor did, I like to use Europe as my example. I'm sure you'll agree, there is tremendous waste in our current way of doing business as usual. Where we disagree is that I believe conservation will buy us time, perhaps quite a lot of time given what I see as a very great amount of waste. I don't buy into Jevon's paradox - as prices go through the roof, people will use less oil. But, for example, if they can get the same "transportation" benefit as they did before by switching to a more efficient vehicle, they will. Result: they travel the same number of miles as before, spend just as much as they did before to go those miles, but use less oil to do so. This is at the heart of your detractor's argument that people buy transportation, not gasoline. That's exactly right - you must consider the utility derived from a consumptive activity, not just the consumption itself. The fact that consumption hasn't dropped much despite a huge rise in the price of oil isn't a counterpoint to this - demand for energy is inelastic and the price will have to go up a whole heap more to get people to change their ways. Also, there is lag built into the system as it takes time to e.g. turn over the fleet of inefficient vehicles with better ones.
Another point that I've tried to make here, also in the "debunk" document, is that concluding that we can't build alternatives quickly enough to matter e.g. more efficient cars or whatever by computing some huge "additional" energy expenditure that would be required is flawed for exactly the reason stated in the debunker's note - it ignores the "going concern" nature of the economy. We are already producing cars, we are already building power plants, houses, etc. These are already counted in current consumption, and it is double-counting to assume some huge amount of additional energy has to be consumed to switch to alternatives. I'm convinced that if we can manage the transition, wind, solar, and nuclear energy, coupled with some use of biofuels, can sustain our present civilization, especially if as much waste as possible is wrung out of it.
Another related problem that I found with your argument is concluding that we can't develop alternatives because we need oil to build them out. Not so! We need energy to build them out, which is not the same thing. Given some overall additional energy resource we can always find a way to make that energy usable by e.g. heavy equipment or whatever. One of the simplest ways that might be done is by displacement. For example, if I can produce more electricity, and I can use that to displace some existing use of oil (by, for example, getting people into plug-in hybrid cars) then I'll free up that oil for use in heavy equipment to e.g. mine coal or whatever. The focus on EROEI (rather than on dollar figures) is a correct one from an engineering point of view, but it's a mistake to assume the EI part must come from oil just because it does so today.
I also wonder about the accuracy of many of the EROEI figures I see. Many inaccurate numbers seem to fly about, particularly for technologies (such as nuclear power) that are disliked for other reasons. You know the old saying, lies, damned lies, and statistics! I suspect many researchers find the numbers they want to support their position (for or against some energy source). Indeed, I expect there is a good bit of double-counting error in many EROEI figures, too. For example, do they count all the energy needed to feed and transport the workers that build the plant or whatever. Oops - we have to feed them anyway (assuming we're trying to avoid collapse).
I won't bother with the economic arguments, economics is hopelessly muddled, indeed the dismal science. At some level the very concept of debt implies an assumption of growth. You're right and your detractor is wrong about this. It need not be true at an individual scale, as your detractor notes, but if you take the entire system as a whole, then it's a closed system, and somewhere, somehow, some growth is needed to make the debt system work.
Where I would disagree is that the system is on the verge of collapse. We could well get crises of various sources (e.g. a wave of personal bankruptcies from the housing bubble and shoddy lending practices), but I don't see any reason why there is any particular "magic number" for the price of oil that will precipitate a collapse of the international system.
Another area where I would disagree with you is that growth necessarily has to involve increased resource (and particularly energy) consumption. Any number of counter-examples (most involving intellectual progress in the sciences and arts) can be found if you look around. It's fair to say that certain types of physical, material growth (most particularly in the human population) must inevitably reach some limits. I won't argue with you that we may be beyond sustainable limits for our planet, though the jury is still out on that.
The bottom line, the indisputable fact, is that oil is a finite resource and we have been running out of it since the day the first barrel was pumped. We can't keep acting like our FF resources are inexhaustible. At some point, we won't, probably not before some real pain is felt, but, IMO, probably before it's too late to preserve our technological civilization."
