Here's one of those studies that apparently shatters our intuition: energy efficiency won't help reduce the use of energy??  Read on for the reason why, all about the "rebound effect" and indirect vs. direct energy consumption.  Again, looks like sustainability requires that we address the bigger picture.

This brings up some concerns I have about the environmental movement in general. I often feel like our emphasis is in the wrong place. Even before it was acceptable to question environmental activism (without being labeled a no-good capitalist hippie-hater) I have felt uncomfortable with some of the campaigns and goals out there. Alternative Energy is a key one for me. I dont think we have an energy source crisis, I think we have an energy use crisis. I dont just mean "energy use" in terms of petroleum (CO2 emitting) energy either. Even if we find alternate energy sources (like the solar panels article I posted on the LCENVS220 group), or more efficient machines/lights, we still will expect the same (or more) amount of work to be done from external energy sources. I think we should focus on realizing what energy already exists in our natural systems and learn to synchronize with that to accomplish our goals, instead. This, I think, will address broader (and dare I add more important?) problems than CO2 emissions.

From the Chief Economist at the Clean Economy Development Center. Also a Grist article (clearly the first Jevons they ran got readership), one of three (I'll post a link to the next one as well), this is a fairly lengthy article on Jevons' that basically comes down to this: "So you'll have to pardon my incredulity when I hear people like Owen claim that Jevons effects are everywhere, because everywhere I look, I can't find them." He then argues that contrary to Jevonian logic "All that's really clear is that for significant periods, energy efficiency has not increased fast enough to cause energy use to go down." Another case for persuing more energy efficiency, not less. One fair critique is that both this fellow and Lovins have vested interests in efficiency efforts. But they do the math right before your eyes, so I'm fairly comfortable with what they're saying. Beyond the math, there are a bunch of theoretical arguments that also force Jevons to take a far humbler stance in environmental and economic theory.

The above article is the Break Through Institute's semi-recent report on the Jevons' Paradox, which I posted additional links to here and debated in class. For the record, the report is favorable. Also for the record, I have not read it completely, and am not laying down final judgment. However: I promised Jim I would respond to this at some point. I still hope to. In the meantime, this is worth musing over (if the link doesn't work, I have the PDF). https://files.me.com/jgkoomey/0aqqfm I really appreciate Break Through and the dismantling of environmentalism's sacred cows, but I'm concerned about this one. Many of their other critiques and analysis seem to have the empirical evidence, but I have yet to be convinced by what I've seen here. Obviously it is a long report, and I have not gotten to read through it entirely, but so far I remain unconvinced. I think they're thinking about the problem in the right way (the economy is a complex social, political, and economic system, it does defy basic models and equations, and if the emergence idea continues to hold up it is a right environment for them) and I really enjoy reading their analysis, but I remain unconvinced by the numbers. Our economy is not composed in such a way that energy is a primary limiting factor to production, which would surely deaden the effect, among other theoretical threats to the idea on both a micro and macro scale. Politically, efficiency measures will continue to allow solar energy and other alternative competitors to carry more weight than they do now, allowing us to free ourselves from the need for energy intense liquids or solids like coal, gas, and oil in favor of less "compact" energy sources. Break Through Institute offers some excellent political analysis, and their efforts at getting outside and away from the usual political roadblocks and antics are appreciated. But I wonder if they

Obviously, its not my expertise either, and I'm woefully ignorant in all this ultimately. But their credentials don't seem to be in deep energy analysis and research, and one academic report where I do find Jesse Jenkins (of BTI, who helped write that report and is an energy expert) still encouraged energy efficiency measures (http://www.brookings-tsinghua.cn/~/media/Files/rc/reports/2009/0209_energy_innovation_muro/0209_energy_innovation_muro_full.pdf). I'm not bold enough to lay down final judgment, but I'm going to need a lot more convincing. BTI makes a lot of convincing arguments that I really like - so far, this hasn't been one of them. But like I said, I'm still reading. And trying to get a handle on what Shellenberger, Nordhaus, and Jenkins have under their belts in terms of economic, versus political (when the two are even seperable), analysis. If there is other stuff worth reading in that regard, I'd love to get my hands on it.
