Ok, read the Galactic energy scale-post. Does an analysis like that scare you? Not me. Holding energy growth constant is a fun exercise, but not realistic. My take-aways: all energies except nuclear are finite in about 200 years barring unrealistic technical advances (like 100% efficiency). Don't forget the catch-up consumption for the other 6.7B world citizens. That would shorten the process. Supply and demand for energy could easily create incentives to better allocate our 7000TW budget. In the long run (and we are talking really long run) S&D should allocate research (nuclear fusion for one, but consumption lowering as well) incentive compatible with our energy budget. The end of the demographic divide suggests falling population rates in 100 yrs. One of the largest drivers of that growth percentage is population growth. But that seems ending. I agree with the CoR there. Another big energy saver. Energy usage is not my worry. Man induced climate change without the political will the make pollution endogenous to markets, that is. Market forces cannot work on CO2 without world wide agreement. I'm a market optimist and a political pessimist.
