I’ve started to lose track of all the things I’ve been reading about housing cooperatives (mostly) in the German speaking world, so I thought I would make a little catalog of resources. Note that many of the articles and organizational websites are in German, but Google Translate is good enough!Continue reading Germanic Cooperative Housing Resources
In my last post, I recounted some of the indications that have surfaced over the last decade that US coal reserves might not be as large as we think. The work done by the USGS assessing our reserves, and more recently comments from the coal industry themselves cast doubt on the common refrain that the US is “the Saudi Arabia of coal” and the idea that we have a couple of centuries worth of the fuel just laying around, waiting to be burned. As it turns out, the US isn’t alone in having potentially unreliable reserve numbers. Over the decades, many other major coal producing nations have also dramatically revised their reserve estimates.
Internationally the main reserve compilations are done by the UN’s World Energy Council (WEC) and to some degree also the German equivalent of the USGS, known as the BGR. Virtually all global (publicly viewable) statistics on fossil fuel reserves are traceable back to one of those two agencies. For instance, the coal reserve numbers in the International Energy Agency’s (IEA’s) 2011 World Energy Outlook came from the BGR; the numbers in BP’s most recent Statistical Review of Energy came from the WEC.
Of course, both the WEC and the BGR are largely dependent on numbers reported by national agencies (like the USGS, the EIA and the SEC in the case of the US), who compile data directly from state and regional geologic survey and mining agencies, fossil fuel consumers, producers, and the markets that they make up.
Looking back through the years at internationally reported coal reserve numbers, it’s surprisingly common to see big discontinuous revisions. Below are a few examples from the WEC Resource Surveys going back to 1950, including some of the world’s largest supposed coal reserve holders. In all cases, the magnitude of the large reserve revisions is much greater than annual coal production can explain.
A good short profile of the city of Freiburg, Germany, and their many sustainability initiatives. Freiburg is a little more than double Boulder’s size — both in population and area, so it has a similar average population density. It’s also a university town with a strong tech sector locally. The whole city was re-built post WWII, but they chose to build it along the same lines as the old city, with a dense core, and well defined boundaries. Today about half of daily trips are done by foot or on bike, with another 20% on public transit. They have a local energy efficiency finance program, on top of the national one administered by KfW, and higher building efficiency standards than Germany as a whole. Half their electricity comes from combined heat and power facilities that also provide district heating and hot water. It seems like they’d be a good model city to compare Boulder to, and learn from.
Passive Passion is a good 20 minute long film introduction to the German Passivhaus energy efficiency standard, which reduces building energy use by 80-95% (depending on what existing code you compare it to). It looks at the roots of the design standard in Germany, and gives a few examples from the tens of thousands of Passivhaus certified buildings in Europe, including single family homes, row houses, apartment buildings, public low income housing, and office buildings. They talk about what makes the standard work: airtight building envelopes, super insulation, no thermal bridging, heat recovering ventilation. The film also looks at a few builders and designers in the US trying to popularize the cost effective implementation of these methods. It’s clearly possible. The examples are out there today. We just have to decide to do it! If we’re going to get to carbon zero, someday our buildings will all have to function something like this.
A presentation from Lawrence Berkeley National Labs, exploring Why Rooftop PV is so much cheaper in Germany than the US. Their feed-in tariff started out quite generous, and has declined predictably over the last several years, which has resulted in the rooftop PV market growing enormously, while installers have been forced to dramatically reduce costs. To the point where today, it’s about half the cost per-watt-installed to get PV in Germany that it is in the US. The physical hardware is the same price, but the process is much easier, and the businesses involved in it much leaner. Good old fashioned German engineering at work, but in the policy realm.
In Berlin, Pirates have won 9% of the vote, and now have 15 seats in the city-state’s legislature. This kind of gradual integration of supposedly “fringe” issues into mainstream politics is valuable, and also impossible in an electoral system like the US has.
A scathing review of an official German government trojan by the Chaos Computer Club. They decompiled the binaries and reverse-engineered the software, and found that not only did it fail to comply with the German constitutional court’s mandate to limit its capabilities, but was so poorly designed and secured as to enable “even attackers of mediocre skill” to completely compromise any machine on which it had been installed. Clearly not the best of German engineering!
A short video from German home fabricator Hanse House. They do both stock and custom homes, but both are fabricated off-site. The video shows their production facility, and some of the techniques for putting together a building in pieces. It’s pretty awesome. Half robotic assembly line, and half humans, building to what’s essentially a CAD specification, with pipes and wires already laid in place within the structural elements before it gets loaded on the truck that takes it off to the building — or rather assembly — site, where the foundation awaits:
And here’s a time-lapse of one of their Passive Houses being assembled on-site:
I wonder if they do multi-family buildings too. What it would take to get a facility like this operating in Boulder County? Other than a rebound in the housing industry of course.
- Forecast: On Climate Change, Cooler Temperatures Bring Hotter Air – Augh, we are prisoners to so many perceptual fallacies. Recency and narration loom large among them. It turns out that the average temperature of the last 12 months is a reasonably strong predictor of whether or not people think they'll personally experience the effects of climate change (a multi-decade to century-scale process). We are failing to deal with problems we didn't evolve to perceive clearly. (tagged: climate statistics fallacy propaganda science )
- In German Suburb, Life Goes On Without Cars – Ah, the New York Times has discovered Vauban! Now if only it had happened when gas was $4/gallon, we might have had a chance. We desperately need more experimentation in urban design, so we can have working examples to look at and build on.

- Spuds in a Box – Build a box whose sides you can progressively remove from the bottom up, plant potatoes in the bottom, and fill with dirt as they grow. Remove lower slats to harvest spuds. I've certainly heard this suggestion from other people too. Will be interesting to see how well it works for these guys. Seems like you could also do this with some kind of bag, and if you sewed in sleeves/tubes periodically, that you could tie off, and then untie when you wanted to reach in and root around for a spud, you wouldn't have to worry about soil falling out when you pry off the boards. Others are supposedly reporting 50kg of potatoes from 0.5 m^2 area. (tagged: gardening green sustainability agriculture food urban design potatoes )
- How Much Do You Earn? – A great annotated visualization of income distribution in the US as of the year 2000. It would be awesome to see an animated version of this, and see how it evolves through time. Turns out I make just about the most likely income in America ($20k), which is far below the mean (and the median). As a "household" though, I suppose we're right about at the median ($40k). Interesting. (tagged: economics wealth taxes government policy visualization )
- The Capitalist Threat – Geoge Soros on Karl Popper's Open Society, from the mid-90s. He rails against the West's failure to extend a helping hand to the post-Soviet nations. He acknowledges that Truth may not be a strong enough motivator for most people, and that within a society that has decided to be Open, there are still many other choices to be made, but somehow fails to mention the way these two things end up pushing an Open Society closed with propaganda, apathy, and misinformation. Political evangelism – the process of deciding what (arbitrary) values your society is going to have – creates huge incentives for those who do not highly value truth to assert authority. I guess that's part of his point though, to robustly inoculate society against those assertions of perfect (authoritarian) knowledge. (tagged: economics politics popper society philosophy )
- First annual Letter from the Gates Foundation – I hate Microsoft, but in the great American tradition of evil corporate fortunes being given back to good causes, the Gates Foundation works on some difficult, important, and interesting problems. I've been curious exactly how and why their focus on population has faded away over the last few years. Not sure this letter (suggested by and modeled after Warren Buffet… who doubled their endowment last year) really answers that question. I get the feeling that the change is partly for PR reasons – that they remain focused on the issue, but don't think it's really productive to make that statement prominently.

- WRI on Bus Rapid Transit v. Light Rail – Given the difference in cost, I really don't understand why BRT doesn't get more consistent consideration in transportation planning. Hopefully someone will notice this study (and hopefully the study is done well…) (tagged: transit transportation brt rail sustainability bus green )
- Bill Gates unplugged – Talked about two problems: malaria, and lousy teaching in America. Not so interested in Malaria (we know what we need to do, we just don't really care… and if all it does is increase human population, is that really a success?), but our inability to make teaching work well reliably is really annoying… (tagged: education ted teaching schools bill gates )
- Till Children Do Us Part – Yeah, having kids can keep you together… out of obligation, or desperation if you're an unemployable 50s housewife. But jeez, who ever thought they actually help a marriage? (tagged: children marriage love )
- Dumping the Refrigerator for a Greener Planet – Well of course I *could* do without a fridge if I wanted to, but why not just get a super-efficient one, or understand better what *actually* needs refrigerated, or design a fridge that takes advantage of the outside temperature for condensing or evaporating coolant, or build an insulated north-facing root cellar into your earth-sheltered house, or use a zeer evaporative fridge, etc. Story seems a little one dimensional.

- Extended Producer Responsibility – I wonder just how much of my predilection for German bike parts comes from their EPR policies, and how much comes from the German design ethos, and how separable those two things really are? (tagged: bike germany green sustainability recycling policy bicycle )
