Fossil Fuel Futures
Smil’s take on the future of fossil fuels seems very similar to that of Steve Koonin (and thus BP), namely that there’s plenty of all of them in the ground for us to damn ourselves to a hothouse hell, if we should so desire. I’m not entirely sure whether this strikes me as an optimistic, or pessimistic statement, but I suspect it’s pessimistic. If we were forced to change our energy systems, I believe (unlike many Peak Oilers) that we would be up to the challenge, dramatically reducing demand without reducing our standard of living, increasing conversion efficiencies, and innovating our way out of the mess partly technologically, and partly socially. If, on the other hand, we have to choose to stop burning fossil fuels, I’m much less confident that we’ll do the right thing.

Where does our energy come from today, and how do we use it? How much does it take to live the Good Life, and what, really, should that energy be used on? Where might it plausibly come from in the future, and what does the Good Life consist of anyway? Energy at the Crossroads by Vaclav Smil at least attempts to get at this stuff, looking at humanity’s utilization of energy, in the past, present, and several possible futures. But the book is a such a dense mass of numbers and graphs that I think I’m going to have to do this in several posts.
The first two sections Long-term Trends and Achievements and Energy Linkages, look at how energy use correlates with other variables of interest, how those correlations have changed through time, and how they vary globally today. If there’s an overarching message here, it’s that nothing about today’s global energy system is straightforward. You can’t make many useful comparisons by looking at only one dimension, such as the total primary energy supply (TPES) utilized or the energy intensity (EI) of a nation’s economy, or by simply looking at mean values without considering the distribution they come from. These variables are not normally distributed. Another clear message is that the 20th century was an anomaly. The explosive global growth in fossil fuel utilization that we have seen over the last hundred years will not be sustained, for a variety of reasons, any one of which would be convincing, but which in combination are downright scary. Either the way our civilization uses energy will be utterly transformed, or the sources of that energy will change dramatically. Or both.

- Is There a Better Word for Doom? – Six disparate views on the value and ethics of actively re-framing the public discussion surrounding climate change. (tagged: politics policy environment communication propaganda climate change science )
- Clay Shirky: How cellphones, Twitter, Facebook can make history – A talk given by Clay Shirky to the State Dept. a month or so ago, on the global, social, ubiquitous and cheap media landscape of the 21st century. Especially relevant in light of Iran's elections and protests at the moment. (tagged: web2.0 media propaganda technology social twitter politics transparency )
- Iran's Disputed Election | A Revolution in Pictures – Images are streaming out of Iran. Hundreds of thousands of people marching. Guns, fires, roads blocked by burning busses, riots and blood in the streets. The para-military storming the University. Protesters improbably evacuating an injured riot cop. Tear-gas ping pong. All revolutions look the same on the ground. They are not in practice ideological affairs. (tagged: iran politics election 2009 photos protest police )
- Gadget Teardowns – How to completely and utterly disassemble… just about anything, from a banana to your brand new Macbook Pro. Unclear whether you can put it all back together again! (tagged: technology design maker )
- The New Socialism: Global Collectivist Society Is Coming Online – An essay by Wired editor and Long Now pundit Kevin Kelly, making analogies between the "socialism" of the 20th century, and the open collaborative systems which have taken hold of the Internet. Larry Lessig hates the fact that he used the S-word, since it's got such a black name in the US, but I'm not so sure it was a bad idea. Actually I think that more than anywhere else, "socialist" ideas can probably work in the world of pure information. We're certainly nowhere near the limits of sharing online yet.
