Should USGBC certify a 15,000-sq.-ft. home as green?

A "speculative 15,000 square foot mansion in Manalapan, Fla., will be the first home of its size to be certified green by the U.S. Green Building Council and the Florida Green Building Council." Is that a good idea for USGBC? That's my question to you. Obviously people are going to build big homes -- and it is better if they have green features. But should USGBC single out such "eco-mansions" for positive recognition? On the big side, the mansion has: ... eight bedrooms, 11 bathrooms, two elevators, two laundry rooms, two wine cellars (one for red, one white), a movie theater and guesthouse. On the green side, the mansion has a: ... state-of-the-art air purification system and eco-friendly light fixtures that will reduce energy consumption by 90 percent. Making this mansion green, probably tacked on additional costs of between 7 and 10 percent ... For instance, instead of using a rare Brazilian cherry for the home's hardwood floors, he's using reclaimed teak -- thus sparing 7.5 acres of Brazilian rain forest ... The house will also have a massive solar panel system (price tag: $120,000), a water system that uses "gray water" from the showers and sinks to irrigate the lawn and gardens, as well as a series of pools, reflecting ponds and water gardens to cool down the 1.5 acre property by 2 to 3 degrees.

Bike routes need names

I recently bicycled from Seattle to Bellevue, Washington, across Lake Washington on the I-90 floating bridge. This trip is not complicated. Once you're on the wide, well-shielded bike lane, you'd think that getting to Bellevue would be assured. You'd be wrong. First, you have to get across Mercer Island. On the island, the bike route leaves the freeway and vanishes into a labyrinth of branching paths. They're beautiful bikeways, no doubt: wide, separated from traffic, well-graded, gracefully curved for smooth cornering -- a pleasure to ride. But they're almost entirely unmarked. Where there are signs at all, they only say "Bike Route." (All of them are bike routes. Duh!) Imagine traveling in a city without street signs -- or with ones that only say "Car Route." Next time you see a sign like the one above that says "Bike Route," remember, it's a symptom of Car-head. (Photo by orangejack via Flickr.)

Is eating local the best choice?

Strengthening community is an important benefit of eating locally

The following is a guest essay originally posted at AlterNet by David Morris, vice president of the Institute for Local Self-Reliance. Some 30 years ago NASA came up with another big idea: assemble vast solar electric arrays in space and beam the energy to earth. The environmental community did not dismiss NASA's vision out of hand. After all, the sun shines 24 hours a day in space. A solar cell on earth harnesses only about four hours equivalent of full sunshine a day. If renewable electricity could be generated more cheaply in space than on earth, what's the problem? A number of us argued that the problem was inherent in the scale of the power plant. Whereas rooftop solar turns us into producers, builds our self-confidence, and strengthens our sense of community as we trade electricity back and forth with our neighbors, space-based solar arrays aggravate our dependence. By dramatically increasing the distance between us and a product essential to our survival, we become more insecure. The scale of the technology requires a global corporation, increasing the distance between those who make the decisions and those who feel the impact of those decisions. Which, in turn, demands a global oversight body, itself remote and nontransparent to electric consumers.
