- Studies in Everyday Life: Exponential Economist Meets Finite Physicist: My Comments on the Limits to Growth
This is my response to the recent post by UCSD physicist Tom Murphy, in which he questions an economist about the physical limits of energy consumption and its implications for economic growth. Following Murphy, I'll respond in four acts.

Well, here it is:
Why am I showing you this? Mostly because its rather striking, partly because it forms part of the things Piketty got wrong thread, but mostly for the relevance to the "infinite growth on a finite planet" type argument. Many people will tell you that infinite "growth" on a finite…
Back in late July, I got email from a writer for Physics World magazine (which is sort of the UK equivalent of Physics Today), asking my opinion on a few questions relating to particle physics funding. The basis for asking me (as opposed to, you know, a particle physicist) was presumably a post…
Over at Cosmic Variance, Sean has a post highlighting some physics blogs that he's adding to the blogroll. Which reminds me that I've been remiss in updating my own links-- I've recently started reading Swans On Tea regularly, and he's got some great science content. Via Tom, I've also discovered…
I really liked Asher Miller's HuffPo article on an assessment of clean energy's scalability by three mostly conservative think-tanks. There are so many analyses done out there that simply work from the assumption that magic technology fairies will erase time and depletion and make it possible for…
That article on exponential growth was amusing, mainly because the author doesn't get the point that energy consumption will have to level off. But then I first heard this point made by Al Bartlett (U of Colorado) over three decades ago. The original article by the physicist was quite good.
[That the graph suggests energy use might have already started to level off in the US is rather interesting and thought provoking.]
