Sustainability Conference II
Sustainability Conference I
The attention given to solar was completely unrealistic. I happened upon Kunstler's blog; he accused Democrats of as much "magical thinking" as Republicans in this post. WRT solar power, he's right. There was no realistic discussion of this: a few people were obviously interested in it, and a few had done enough research to know the reality, but did not seem to have been dissuaded.
1) The keynote speaker said the cost of solar is going down. Bzzt. As I noted earlier, it has been going up in lockstep with oil prices, though it seems to be plateauing. If each dollar buys less solar panel, given a fixed or declining amount of money left over after other purchases (which is what the End of Suburbia was preaching), you aren't going to be able to buy as much solar in the future. My suspicion is that there are two causes for the rise in price: increasing demand with flat or slowly increasing supply, and subsidies. The former was driven by the increase in fossil fuels in 2003-2006, and may eventually correct itself. The latter is self-fueling (see below).
2) How much power does the average user use? The US national average in 2001 was 888 kW-h/month. Mine is something like 600 kW-h per month. If I had a 1 kW solar array and got 6 hours insolation (direct solar exposure) per day for 30 days, I could generate 180 kW-h per month. That's 1/3 of what I need, 2/3 if I double the size of the system. And I live in New Mexico where we get 6-7 hours of insolation a day (and we have something like 260 cloud-free days per year); the calculus is much tougher if I live in NYC or Seattle where they get far less insolation.
3) Two costs were given at the conference. One was $16,000 for a 1.5 kW system (roughly $10/W). Another was that the typical system costs $0.25 - $0.40 / kW-h to operate. Someone asked if that included sell-back (net-metering). The answer was obscure (I don't think the speaker heard it correctly), but the proper answer should have been: no, but it doesn't matter much. You can only sell back at the rates you pay for electricity, which is about $0.10/kW-h, so it's still 2.5-4 times the cost of commercial supply, i.e. it's no free lunch. Also, you can only sell back to the electric company up to the amount you use. Look at it this way: if you are currently paying $60/month for electricity, you will be paying $90/month for the loan for the system after accounting for rebates and sell-backs. You will also still have that monthly bill from the electricity company, but it will only consist of the subscriber fee plus tax.
Note that these were for grid-tie systems. An off-the-grid system will run at least twice as much, and the batteries require extra care (a well-ventilated area to dissipate the hydrogen generated during storage) and replacement on a regular basis (10-20 years). Incidentally, "grid-tie" and "net-metering" means that the PV system produces more than you use through most of the day, produces just about what you need in the afternoon/evening, and you rely on the grid at night and in the morning; which means someone still has to run a power plant.
3a) Let's look at this. The 1500 W system will be operational in a location that gets about 6 hours of insolation per day. That comes to 65700 kW-hours in the 20 year lifetime of the system. That means the cost of electricity is about $0.24/kW-h, rather toward the low end of the other prediction. This doesn't take into account system degradation, line losses, and so on, which would all drive the cost per kW-h higher. Take the $6,000 tax rebate back and it still comes to $0.15/kW-h. This system was enough to cover the speaker's own daily use.
3b) One thing that occurred to me during the movie I discussed in the previous article (link at top) -- and was later pointed out by one of the builders in the panel session -- was that in the coming era of higher energy costs (remember, this is their basic assumption), the system would be more and more valuable. In other words, if electricity costs increased to something on the order of $0.20/kW-h, the system would be viable at the low end of the calculations above. It would definitely pay for itself quicker if energy costs rose above $0.25/kW-h. That's an interesting bet, especially if you switch to a plug-in hybrid.
4) One of the builders, a self-described long-time left-wing activist, made a point of saying how the Bush Administration had "hammered down" any subsidies for solar power.
4a) Let's review the Clinton Administration environmental initiatives:
This isn't to say that the Bush Administration is exactly the Teddy Roosevelt Administration (or even the Nixon Administration) in terms of its environmental activity, but Clinton only topped him in rhetoric. However, from what I can find, current Climate Change spending is somewhere in the $3-4 billion dollar range. Clinton: 40% increase in 8 years, Bush 400% in 6 years. Of course, since you can't actually pin those numbers down to find out exactly what we're getting for the "investment", I'd guess we had a case of Clinton = Bush = 99% BS. I say that because I suspect that both administrations counted obvious boondoggles (such as ethanol from corn programs) as Climate Change remediation.
I also found that the Bush rhetoric has been a regular but undiscovered drumbeat. This article's author thinks the rhetoric is new, despite earlier press releases like this, this, and this. I think Kunstler is right to be cynical.
4b) Let's review the politics and economics of subsidies. Subsidies are sometimes known as "corporate welfare", which, as we all know, both Republicans and Democrats are against. It is a mystery how they keep getting passed, init? In the solar industry, the subsidies happen to help out little Mom & Pop companies like British Petroleum, Canon, Kyocera, Mitsubishi, Sharp, and GE Energy. Also keep in mind that the subsidies are not secret: the suppliers know about them, too. They know that the bargaining limit for prices will go up by the amount of the subsidy, so they can basically leave production levels where they were before the subsidy even as they raise prices by the amount of the subsidy. The subsidy is no benefit to the consumer when it all goes to the manufacturer, so this merely becomes transfer from taxpayers to PV manufacturers. This is probably one reason for the rise in PV prices, especially in Europe. Still in favor of them?
Conclusion:
I believe we would be much better off with fossil fuel energy prices that more closely reflected the social costs. That's what Mankiw's Pigou Club promises, but it's also what a cap & trade program would bring. Both Kyoto and the 1990 Clean Air Act contain forms of cap & trade programs; the SO2 program in the 1990 Clean Air Act is thought to be very successful (which Administration signed that?) at reducing Acid Rain (resulting in things like this). Raising the cost of production of coal-fired or natural-gas-fired electricity by requiring providers to buy CO2 permits does a much better job of encouraging alternative solutions for two reasons:
First, people might not choose solar. They might choose to cut down on energy consumption with, for example, more insulation, better house design, more efficient vehicles, and/or better urban design. This would be a much better way of balancing our needs with the supplies and AGW forecasts because it would stretch existing supplies. This is the soft energy path favored by Amory Lovins. It is also an example of the principle of substitution noted by Julian Simon, and an example of adaptation recently suggested by Roger Pielke in Nature. Cutting energy use could also be combined with the adoption of alternative energies, enabling us to get there easier. In other words, rather than replacing my entire 600 kW-h usage with solar, I could perhaps cut my energy usage by half and then buy a 1500 W system that meets all of my needs.
Second, making fossil fuels more expensive would not subsidize and therefore support the least efficient providers of solar energy. If there are, say, three providers, the most efficient (least cost) provider would sell all he could make at a price that the competitors could not match up to the point at which consumers would turn to the next least cost provider. Once demand rises that high, the least cost provider would raise his prices to those of the competitor and pocket the extra income because the only alternative consumers have is not the least cost provider. If demand is high enough that the two most efficient providers cannot meet it all, they will raise their prices to meet those of the highest cost provider. As demand continues to increase, the least cost provider will see higher returns, and can therefore command more investment to expand his facility to the point that he might put the least efficient (highest cost) provider out of business. In such an environment, the highest cost provider has an incentive to try to improve his processes to match those of the least cost supplier; either that or risk going out of business altogether (which is fine, since it leaves the two lower cost providers in business at the prices commanded by the second lowest-cost provider). The subsidy thwarts the entire scheme by allowing even the highest cost provider to raise prices in order to capture some of the subsidy from the consumer. It is thus an incentive to capture market share and a disincentive to do it by increased efficiency at using inputs. More investment will go toward marketing than engineering and production management.
Unfortunately, the default setting of people at these conferences is
NOTE: Now that I'm looking up the Cuba film, I'm sorry I missed it. Apparently, one of the responses to the loss of their patron, the Soviet Union, and the subsequent collapse of their system was to establish farms with property rights (property rights in a broad sense - it is owned by a local community) and private markets (at which said community trades). The same thing that brought China out of the Cultural Revolution. Private property saves the day again?
Still, it's limited freedom within an overall oppressive atmosphere. One rooftop farm has this description: "Running free on the floor are gerbils, which eat the waste from the rabbits, and become an important protein source themselves." Yummy, can't wait. Most reviews of the film are the same fawning fluff, but only in a picture caption on this did I find a reference to the private markets. And abelardlindsay comments on The Oil Drum post about the film that Cuba is much less efficient at turning energy into wealth than its neighbors.

4a) Let's review the Clinton Administration environmental initiatives:
- Signatory to Kyoto, never submitted to the Senate for ratification, never did anything about it.
- Some 11th hour rules made in 2000 (first directed in 1996) on arsenic in drinking water changing the maximum exposure level.
- Propose a “Million Solar Rooftop” program, but never pressed it. That's about it.

Unfortunately, the default setting of people at these conferences is
Democrats good, Republicans bad (and libertarians evil embodied)Or, alternatively
Command and Control, Tax and Spend, Policymaking Government Good, Market-based Reform BadIf they could perhaps be bumped off their default settings, I think I could stand listening to the rest of what they had to say. Unfortunately, they wanted to start the second half of the conference worshipping Cuba as the example of the path we should take with another film called The Power of Community. Sorry, I am actually offended by cults of tyrannical, murderous, autocratic personalities.
