To get serious about sustainability, move back to the city.

According to Witold Rybczynski (writing in The Atlantic), it's time to get serious about living sustainably. Currently, we do that by going out to buy the latest and greatest gadgets for saving energy. There's a much better foundation for accomplishing this goal of living sustainably:

The problem in the sustainability campaign is that a basic truth has been lost, or at least concealed. Rather than trying to change behavior to actually reduce carbon emissions, politicians and entrepreneurs have sold greening to the public as a kind of accessorizing. Keep doing what you’re doing, goes the message. Just add a solar panel, a wind turbine, a hybrid engine, whatever. But a solar-heated house in the burbs is still a house in the burbs, and if you have to drive to it, even in a Prius, it’s hardly green.
Instead of putting little Band-Aids on the big problem, Rybczynski argues that we ought to move back to the city. We would save much more energy by prohibiting spread-out low-rise buildings than by pasting solar panels on them. "A reasonably well-built and well insulated multifamily building is inherently more sustainable than a detached house." He advocates three or four story "walk-ups," which don't require elevators. These can create sufficient density "about 50 people per acre, to support public transit, walk ability and other urban amenities." Another important approach is to focus on the way we construct our commercial buildings. When we combine residences with commercial and institutional structures, buildings consume 48% of our energy, more than any other sector.

National Geographic on the state of solar power

The September 2009 issue of National Geographic has a comprehensive series of articles on the state of solar power. Here's the online version of one of the articles. What is the potential of solar power?

"The total power needs of the humans on Earth is approximately 16 terawatts," he said. (A terawatt is a trillion watts.) "In the year 2020 it is expected to grow to 20 terawatts. The sunshine on the solid part of the Earth is 120,000 terawatts. From this perspective, energy from the sun is virtually unlimited."

A dude, a camcorder and Earth Day in St. Louis

I wandered around at this year's St. Louis Earth Day celebration with a camcorder to capture some of the many images and sounds. I boiled my raw video down into two short videos, each of them lasting about five minutes. The first one is the "fun" video--you'll see what I mean. I'm assuming that some of the scenes at Forest Park will give you a smile or leave you shaking your head. Free hugs, anyone? Or how about some sound therapy? And do consider the computerized body analysis administered to me by a chiropractic group working really (really) hard to sell me their long-term services. BTW, I took their test assuming that any legit test would pick up on a rather serious condition I'm dealing with--half of my left hand has gone numb and my left arm is at 1/2 strength due to a pinched nerve; it's so bad that I'm almost certain to have neck surgery in a few weeks. But the elaborate computerized scan didn't pick up on that major issue. I did learn that my gall bladder is in great shape, however. Editing down these videos, I was surprised at how much music one can hear at the festival. Musician Leslie Sanazaro, who has often promoted "green" issues, is featured at the end of this first video (a few months ago, I produced a three-part interview with Leslie). Enjoy! Now for the "serious" interview. Among all the people attending the fair were a few contractors who sell products and services that can really make a dent in the amount of energy used by your home. The first half of this short video features a firm (Home Green Home) that does elaborate energy audits for about $400. According to Marc Bluestone, up-front cost would be a bargain based on the amount of energy you can save (more than 20% of your energy bills). The second firm, Missouri Solar Living, installs solar equipment for water heating and electricity. You'll hear some compelling facts and figures, especially about solar hot water. Note: I don't know any more about these two firms than you'll see on this videotape, but I did enjoy meeting these guys at Earth Day and I appreciated hearing energy-saving information from two companies who are actually doing substantial work out in the field.

Making numerical sense of the “bailout”

I’m sitting here, stunned by the amount of money that is about to be casually taken out of the U.S. Treasury to “save” the economy.  I’m highly suspicious.  I’m not sure this taxpayer revenue is needed or that it is any more than a band-aid.  Surely, Wall Street (or other…

Think solar, U.S.

Scientific American has just published a comprehensive article on how to switch the United States substantially over to sunlight. The headline: "By 2050 solar power could end U.S. dependence on foreign oil and slash greenhouse gas emissions." The cost of this immense clean-energy-producing plan would be $420 billion. That's a HUGE…
