Blogger Nathanael Greene takes on Philpott re: biofuels

The Natural Resources Defense Council evidently remains pretty sanguine about biofuels as a "solution to energy dependence and global warming." Over on the group’s Switchboard blog, senior policy analyst Nathanael Greene recently took exception to some unkind words of mine on cellulosic ethanol. I responded in the comments section. I hope a robust debate follows.

Small wind in urban settings

I never really thought much about small wind's potential as a significant source of a city's electricity supply. Windmills in a urban setting? I just don't see it.

Didn't see it, that is, until I saw it. The other day I biked by 1303 Alabama St., in the Mission District of San Francisco. Softly -- very softly -- whirring overhead is a 1.9 kW Southwest Windpower Skystream windmill. The Choose Renewables resource estimator says that it's a class 3 wind site, but I wouldn't be surprised if it's actually higher. As any San Franciscan knows, the Mission can be very sunny and pleasant during a summer day, but on summer evenings, as the marine layer moves in, the wind just nukes over Twin Peaks and the South Mission/Noë area can be a wind tunnel.

The result, I expect, makes for propitious economics. The house also has a 5 kW SunPower solar system. California's system peak is shifting later and later, which is being reflected in PG&E's tariffs. The old E-7 Residential Time of Use (which is being phased out) had a summer peak of 12 to 6 p.m. The new E-6 has a summer peak of 1 to 7 p.m., and a partial peak of 7 to 9 p.m. In practice, that means that as the solar system's production winds down in the early evening, the windmill steps in and produces electricity that would have cost up to 53 cents/kWh if bought from the utility.

That's just a wonky way of saying that wind and solar are like peanut butter and chocolate: great on their own, but even better together.

Polar bear ventures far inland, shot to death

Having boldly gone where no polar bear has gone before, a 3-year-old female polar bear was shot dead 250 miles inland in Fort Yukon, Alaska, last week. Hunters who thought they were tracking a grizzly bear shot the polar bear in what they say was self-defense; the U.S. Fish and Wildlife Service is investigating the […]

Umbra on organic vs. natural foods

Dear Umbra, I’m trying to convince my sister that there is a difference between all-natural and organic products, and she doesn’t think there is. I’m pretty sure there is a difference, I just don’t know what it is. I look at the ingredients of some of the food she buys that she says are “natural” […]

Gore’s Alliance for Climate Protection unveils ambitious $300 million ad campaign

If you read Juliet Eilperin’s great rundown in the Washington Post, you know that today marks the launch of a massive PR effort from Al Gore’s Alliance for Climate Protection. Gore has concluded that U.S. politicians will continue to be timid on climate change until the public demands otherwise. “The simple algorithm is this: It’s […]

Crude substitute: The folly of liquid coal

I’m moving this back to the top — the link was broken before, but now it works. This is a must-watch. A stellar new 10-minute video from NRDC:

Similarities between the skin cancer and climate change ‘scams’

I was recently reading The New York Times and saw a fantastic ad:

Recent research indicates that the benefits of moderate exposure to sunlight outweigh the hypothetical risks. Surprisingly, there is no compelling scientific evidence that tanning causes melanoma. Scientists have proven, however, that exposure to all forms of ultraviolet light -- both indoors and out -- stimulates the natural production of vitamin D. And research has proven that vitamin D protects against heart disease and many types of cancer, in addition to providing other important health benefits.

If you go to their website, you can read all about it.

The similarities between the "skin cancer" scam and the "global warming" scam are all too clear. First, according to this website, there is actually no evidence linking sun exposure with cancer. Amazing. I thought the epidemiological data nailed that connection decades ago. Boy, was I wrong! This is similar to the fact that there is no evidence linking carbon-dioxide emissions with climate change.

Cheap at any price!

More news from the world of cheap coal: Santee Cooper said Wednesday that the first phase of its proposed Pee Dee coal-fired power plant [in Florence County, South Carolina] will cost $1.25 billion, up from its original estimate of $998 million. Even that may be under-stating it: Blan Holman, a lawyer for the Southern Environmental […]

Listing polar bears as endangered species could … harm polar bears?

Via an email from The National Center for Public Policy Research:

The ad is being released in conjunction with a National Center for Public Policy Research policy paper, "Listing the Polar Bear Under the Endangered Species Act Because of Projected Future Global Warming Could Harm Bears and Humans Alike," by Peyton Knight and Amy Ridenour.

The paper questions the wisdom of listing the polar bear as threatened based on environmentalist organizations' projections of future global warming because:

• Listing the polar bear could have adverse affects on bear conservation efforts.
