Energy at the Crossroads by Vaclav Smil (Part 2 of 2)

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.

Energy at the Crossroads by Vaclav Smil (Part 1 of 2)

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.

Georgia and Russia, sittin’ in a tree

Pravda has put out a helpful timeline of the current Georgia-Russia conflict

Maybe I have a one track mind but, I don’t think this kind of conflict often erupts for purely egotistic political reasons. There’s a lot of energy backstory that isn’t being told in that Russian chronicle, such as the sabotage by someone of natural gas and electricity supplies headed into Georgia from Russia (gee, I wonder who it could have been… in the depths of a Caucasian winter in January 2006), the subsequent commissioning of the South Caucasus gas pipeline in December 2006, and all of the wrangling that’s been going on over the trans-Caspian gas pipeline since the mid 90s (Russian and Iran don’t want it, everyone else does, because Russian and Iran have gas already, and everyone else gets their gas from them).

Perhaps the largest diplomatic stick Russia can wield today is its oil and gas reserves (assuming they don’t want to actually like, invade a NATO country, or shoot off some plutonium fireworks), and they are jealously guarding the ability to wield that stick. Georgia has successfully circumvented them with the pipeline from Baku to Turkey (and eventually on to Europe), and I think in part now, they’re paying the price, so that others in central Asia with gas they’d like to independently pipe out of the region, including, perhaps most importantly, Iran, think twice about setting up their own circumvention. For instance, Iran built a pipeline into Armenia. It was supposed to be extendable, eventually onward to Turkey and Europe. Before it was built, Gazprom bought a controlling interest in the pipeline company, and summarily reduced the diameter of the pipeline from 1.4m to 0.7m, making it unable to carry enough gas for extending it to Turkey and Europe to be worthwhile.

I think that the blurring, or erasure, of the lines separating nations and corporations is interesting, and at least somewhat unexplored.  (Maybe one major difference is that a nation-corp can more dependably rely on its nation’s armed forces to step in occasionally.  Though, historically, US companies have had a pretty good chance of getting help on demand, at least in Latin America).  We wouldn’t be surprised if Exxon did something like buy up a potential competitor, but when a nation does it, how do we react?  In oil and gas, all of the major players are nation-corps. I think this is actually one of many very good reasons for the industrialized world (that, by and large, has used up its oil and gas) to invest heavily in renewable alternatives to oil and gas. If we develop renewables for national security (and environmental) reasons, the costs may well be reduced enough that other economies can use them simply because they’re cheap, distributed (more difficult to sabotage than a pipeline or LNG terminal), and don’t require you to be on good terms with Russia, or Iran, or Saudi Arabia, or Venezuela, or get permission from the IAEA to spin up your centrifuges.

Pipelines are beasts curiously subject to consensus, because they are so easy to destroy.  If anybody in the area doesn’t want one to function, it doesn’t.  So Russia may well be able to maintain its pre-eminent position as gas supplier to Europe for a long while to come, and keep the squeeze on in central asia indefinitely.  At least, until we stop relying on natural gas.  Or until someone in central asia really decides it doesn’t want Russia’s natural gas infrastructure to function.  Now wouldn’t that be fun for everyone!

Basic Wrenching at Caltech

We had our first Basic Wrenching class yesterday at the Caltech Bike Shop. I think it went pretty well. Maybe a little bit chaotic, and a few too many people – but that’s okay. Someone brought chocolate chip cookies, and someone else brought chocolate banana bread! A great start!

I helped 9 people take their front wheels off, remove their tires and tubes, and then walked them through patching one of the many tubes that we had laying around at home with holes in them. Steve from Open Road graciously gave us some patch kits and chain lube and tire levers for the effort. John McKeen walked people through adjusting their brake and shifter cable tensions, and Katherine gave people bicycle anatomy walkthroughs. I think Ian kind of floated from one place to another. There were at least 20 people total. Hopefully most of them got something out of it.

The shop itself is almost completely barren – everything but the tools was jettisoned for the South Hovse remodel unfortunately, and the Moore-Hufsteadler funding hasn’t come through. They (I think rightly) pointed out that we really need to have some procedure in place to keep the tools from diffusing away. I don’t really want to call it “theft”… but when people can borrow things, they do tend to end up making a kind of random walk away. That’s just (social) entropy. But we really do need workbenches, and a couple more stands, and a big toolbox, and pegboards that haven’t had all of the tool outlines turned into phalli. So I hope we can agree on a structure that we’re willing to implement, and they this is acceptable.

There’s lots of room in the “rafters” of the shop to hang bikes, if we can get some hooks and cables set up somehow, safely. I think it would be great if we could operate like the Bike Oven, letting people work on abandoned bikes we get from Security, and then buy them for cheap. And it would be nice if we could have a selection of patch kits, tubes, and tire levers, that people could buy at cost (or at least cheaply).

Maybe what we really need is a separate bike shop “membership”, with a minor fee to cover consumables like oil and patches and grease and gloves, etc., and to serve as an official designation for the people who have access to the shop. Then, at least once a week, I think we should commit to having a mechanically inclined person down there willing to help anybody else out who wants to work on their bike, so that it’s a Caltech Community resource, instead of just a closed club.

I think I’ll see if I can show up (extra) early next Monday, and do a little tool organization, and make sure to bring the work stands from home, and maybe my own personal tools, since it seemed like we really were lacking some basic stuff – or it just wasn’t findable.
