NimbyThis morning, NPR's Morning Edition ran an energy NIMBY story with a twist: An "In My Back Yard" piece titled, "City Dweller Laments Loss Of Urban Trees," detailing the difficulties power companies can face in dealing with urban homeowners.
Utility people say they can't win. If they trim too aggressively, residents, like me, complain that they are destroying the canopy in an old neighborhood. But if untrimmed trees take out power lines during a storm, those same residents jump on the phone and demand that the utility turn the juice back on right away. Earl Eutsler is a District of Columbia arborist. He says there's only one way to solve the conflict between trees and power lines.

"Planting the proper tree in this space. For example, the amur maple we installed in front of your house," he explains.

"Proper tree, proper place" is the motto for the city's plan to replace tall trees under power lines with species that are more, shall we say, cooperative.

Eutsler takes me for a drive in his natural gas-powered car to show me what this might look like. He points to a series of purple leaf plum trees, planted in the "tree box," or curbside plot along the street, where stately elms used to stand. The new trees are "starting to establish themselves," Eutsler says. "These here that are already 15 feet are going to get another 10 feet tall, and that's really it," he says.

"But they're not really providing shade," I counter, staring at a perfectly respectable stand of trees that will never soar or form a graceful allee, "Not in the sense you can go out and sit with your neighbors under a tree like that."

"No, you're right," says Eutsler. "But it's more manageable, it's less dangerous."

City foresters encourage residents who want tall trees to plant them closer to homes, but away from the power lines. Despite my love for big trees, I'm not too crazy about having them right next to the house.

I'd love to have seen the look on the face of the Pepco guy when the reported made his comment about the allee.

Actually, there are other alternatives. In Canberra, where I grew up, from the 1950's to the 1980's the utility put all the poles and their wires in the backyards, so no street trees were ever affected by power lines. People in Canberra are less inclined to have large trees in their backyards, probably because all backyards are fenced. From the 1980's on, all utility services have been placed underground, in PVC pipes (which tree roots avoid) so there is no adverse interraction between trees and utility services.

Canberra has some of the most attractive streetscapes of any post-war urban/suburban environment I have visited, although that is of course in the eye of the beholder.

Here in St.Louis Missouri they are working on putting the power lines underground. Even with aggressive tree trimming we often get power outages. I think it's a worthwhile investment to get both better reliability and not have to damage the tree canopy.

Yes, put the power lines underground. That's the solution. Underground power is required by most building codes for new subdivisions, and it's much better if one has storms or earthquakes.

Why don't you have the power lines underground in the US? I remember when I visited California and thought the power wires all over the place made it look like a third world country.

Power lines underground have a tendancy to flood in some areas and are much costlier to repair if they are damaged due to water or earthquake.

A Billion Miles Under Nuclear Energy (Updated)

And the winner is…Cassini-Huygens, in triple overtime.

The spaceship conceived in 1982 and launched fifteen years later, will crash into Saturn on September 15, after a mission of 19 years and 355 days, powered by the audacity and technical prowess of scientists and engineers from 17 different countries, and 72 pounds of plutonium.

The mission was so successful that it was extended three times; it was intended to last only until 2008.

Since April, the ship has been continuing to orbit Saturn, swinging through the 1,500-mile gap between the planet and its rings, an area not previously explored. This is a good maneuver for a spaceship nearing the end of its mission, since colliding with a rock could end things early.

Cassini will dive a little deeper and plunge toward Saturn’s surface, where it will transmit data until it burns up in the planet’s atmosphere. The radio signal will arrive here early Friday morning, Eastern time. A NASA video explains.

In the years since Cassini has launc…

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.


The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.

What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…

Why Nuclear Plant Closures Are a Crisis for Small Town USA

Nuclear plants occupy an unusual spot in the towns where they operate: integral but so much in the background that they may seem almost invisible. But when they close, it can be like the earth shifting underfoot., the Gannett newspaper that covers the Lower Hudson Valley in New York, took a look around at the experience of towns where reactors have closed, because the Indian Point reactors in Buchanan are scheduled to be shut down under an agreement with Gov. Mario Cuomo.

From sea to shining sea, it was dismal. It wasn’t just the plant employees who were hurt. The losses of hundreds of jobs, tens of millions of dollars in payrolls and millions in property taxes depressed whole towns and surrounding areas. For example:

Vernon, Vermont, home to Vermont Yankee for more than 40 years, had to cut its municipal budget in half. The town closed its police department and let the county take over; the youth sports teams lost their volunteer coaches, and Vernon Elementary School lost th…
