Which is why it is good that there are people like Al Gore who are not too price-sensitive around and willing to pay the large cost increase. Such people are needed to get the market going before economies-of-scale start to lower the costs.

Well, it is interesting that you don’t seem to mind people not paying the costs associated with dumping CO2 into the atmosphere but are sensitive about any subsidies that are going toward helping new energy sources compete that are not resulting in significant CO2 emissions until they can begin to realize their economies of scale. (And, by the way, do you have cites to back up the price claims that you have made here? I am willing to believe they are correct but I would be curious to know where these numbers come from.)

jshore, I don’t know how many times I have to say it, but I will persevere. I say again, the first step I have repeatedly advocated is the “Three R’s” … Reduce, Reuse, Recycle. I think that we should reduce our consumption in all areas, particularly energy. Conservation is always cheaper than new production. You have accused me of not advocating anything that Mobil doesn’t want … how many times have you heard Mobil say we should cut our gasoline consumption?
This is one of my problems with Al Gore. He doesn’t seem to even get to Step 1, “Reduce”. Instead, he seems to think that it is fine to consume many times the average citizen’s consumption, and then excuse it by making payments that only wealthy people can afford. Call me simple, but I fail to see how this is a prescription for a renewable future for the world. Having lived and worked extensively in the Third World, I am interested in solving the world energy problem, not in solutions that only the wealthy can afford.
I am sensitive about the current large subsidies for wind and solar because
-
both wind power and solar power are not new technologies, and the prices are not dropping fast enough to make them economically competitive any time soon. To do so, they would have to cut their costs to a small fraction of the current cost, and
-
because of their intermittent nature, neither wind nor solar can replace current power generation, but only supplement it. We will still need to have the full conventional generation capacity for times when the intermittent sources are unavailable. This means that we will have to pay for both conventional and solar/wind, which makes them uneconomical.
The TVA sells power for about 7.3 cents per KWh. Their generation costs are likely around half of that. They pay for, not sell for but pay for, renewable energy at 20 cents per KWh. For the renewable source to function without subsidy, they will have to produce their power for something on the order of 4 cents per KWh … economies of scale will cover only a small part of that.
Look, I’m a passionate advocate of renewable energy, I used to teach it for the US Peace Corps, it’s wonderful stuff in the right situation. But I am also a realist. It is not a feasible substitute for a meaningful amount of fossil fuel, which is why among other reasons, even with the subsidy, wind plus solar is only a hundredth of one percent of the TVA generation mix.
[QUOTE=jshore]
Since you seem so pessimistic about getting off fossil fuels, I wonder what you think is going to happen when we run out of them. Is the world economy just going to collapse under the weight of the higher energy prices that this will force on us?
[/QUOTE]
By no means. What will happen is what has happened many times in the past with a variety of commodities as they became scarce. Over the period of centuries during which the fossil fuels will run out (coal reserves are estimated at several hundred years), prices will rise, other forms of energy will come on line, and the world will contine.
My thanks to you,

PS — The numbers for the TVA renewable production are available here. General TVA electrical production figures are here. Other associated numbers are available on the TVA web site, I don’t have the exact cites at hand.
PPS — Speaking of citations, perhaps you have a citation showing the cost you think people should pay, that, is the dollar cost of emitting a kg of CO2 into the atmosphere? What does that kg of CO2 cost us, and how is that cost determined?
