This may lead me to a tangential take on the thread topic itself. I don't want to get mired in questions of ALEC or lobbying groups - there are issues there, no doubt, but teasing them out is not my area of expertise. But I would like to reiterate what I've said to Nessie before. I don't have some belief in a magical invisible hand of the market which will always result in the best outcome for society (in that I don't believe that economic definitions of 'efficiency' are remotely applicable to broader society). But I do think that markets are a very powerful tool to change human behavior.
Accurate pricing is absolutely critical, of course, which is why I favor regulators trying to eliminate externalities as much as possible. In general, though, both scarcity and unintended side-effects of a given product should drive up prices, resulting in a market-driven search for better and overall cheaper alternatives. A whole lot of ideas will get tried out and discarded, but the best ones will become the new gold standard. That's how the world gets to be a better place.
I don't think that one needs to be a Malthusian to be concerned with the issue of scarcity - energy or otherwise - in today's world. It's clear that we will face unprecedented challenges in the next century as the global population peaks in the 9-10 billion range, and as our global per capita consumption dramatically increases through development. I don't want to be a starry-eyed optimist and assume that all problems will magically disappear with a technological panacea, or that dealing with these problems might not get messy. But I think that to assume we'd descend into the depths of genocide or a global resource war is unnecessarily pessimistic. Our world
has gotten so much better for those living in it, even as our demands on food, energy, and resources has reached unprecedented peaks. I think we can muddle through, though it won't always be pretty.
