Billie Joe spends a green day rebuilding New Orleans

With Habitat for Humanity

In a recent collaboration with U2 on "The Saints Are Coming," Billie Joe Armstrong of Green Day sang about a house in New Orleans. But he spent this weekend hammering soffit onto one, as a …

A modest proposal: Treat bikers as human

What would we do if bikers’ lives were worth as much as auto convenience?

Great idea for a new law: Spouses and children of all traffic engineers must travel on the streets planned by their loved ones using a bike at least 50 percent of the time. What would happen then? Probably this.

Green Knoxville?

The pro-enviro solution that dare not speak its name

Trains are the forgotten mode of transport, at least in the U.S.

"Because if your ideas are any good, you'll have to ram them down their throats." Take electrified rail, for instance. Here's a sad report from Dean Baker of The American Prospect, one of the best reporters going today: I was shocked to discover in a conversation with a congressional staffer that rebuilding the country's train system is a topic that is strictly verboten on Capitol Hill. I was reminded of this when I read that a French train had set a new speed record of 357 miles per hour. Trains are far more fuel efficient than planes. Even at much slower speeds than this new French train, service across the Northeast and between the Midwest and Northeast can be very time competitive with air travel, after factoring in travel times to and from airports and security searches. It is remarkable that politicians don't even have trains on their radar screens. And, if you haven't seen the video of what an electrified train can do, check this out.

CO2's lowest hanging fruit?

We’re inside it

We all know buildings are part of the global warming problem, but many people don't recognize how central they are to the solution. A recent UNEP report -- "Buildings and Climate Change: Status, Challenges and Opportunities" -- shines light on how relevant and accessible building-related climate change solutions are. Achim Steiner, UN Under-Secretary General and UNEP Executive Director, said: By some conservative estimates, the building sector world-wide could deliver emission reductions of 1.8 billion tonnes of C02. A more aggressive energy efficiency policy might deliver over two billion tonnes or close to three times the amount scheduled to be reduced under the Kyoto Protocol. The International Energy Agency estimates that a total global switch to compact fluorescent bulbs would in 2010 deliver C02 savings of 470 million tonnes or slightly over half of the Kyoto reductions. We have to ask what the hurdles are -- if any -- to achieving such positive low cost change and set about decisively and swiftly to overcome them, if they exist at all. I realize Kyoto is not our final goal, but the point here is the potential for harvesting carbon reductions from buildings is immense, and most of solutions are 1) with us already and 2) relatively low-cost to deploy. The challenge is largely changing practices. But as Achim notes, the hurdles in the building sector, unlike some other sectors, may not be very substantial.

The adults in my community

Americans spend 95 percent of their lives indoors

I was recently working in the front yard on one of those warm days that sporadically appear in March and April. Patricia came by, walking her bike up the hill and still wearing her bike helmet. She has watched my daughters grow up and always asks about them. Patricia is a thinking person and I always enjoy chatting with her. The topics included status seeking (my favorite), electric bikes, her present job, an article in The New York Times about global warming, and her ninety-something year-old multimillionaire mom. Patricia signed off when the neighborhood drunk bellied up. What village or town would be complete without one? Turns out he's on the wagon and I wished him luck. My family has watched him stagger back and forth to the liquor store for almost two decades and he has taken way too much interest in my oldest daughter lately, who made the mistake of washing a car out front in a bikini last summer.
