How to reach Joe Sixpack on climate issues

Gore's spending $300 million on it, but actually, I think a more direct approach might do the trick.

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.

Spitzer’s successor may continue doing good for green

Snark aside, the ascension of the former Lt. Gov. David Paterson could very well mean good things for environmental progress. He recently chaired the state's Renewable Energy Task Force, which recently recommended an increase in the state's Renewable Portfolio Standard. As he comes in without a direct voter mandate and has to deal with a fairly acrimonious legislative environment, what better way to establish a popular mandate than adopt something super popular -- say, solar energy, which polls in the 90th percentile and makes a lot of jobs at the same time -- as a signature issue?

And if you want to play out this fantasy strategy further, the new Guv (who started, what, a few hours ago?) has to start thinking about getting reelected. And his potential challenger has already laid out a fairly ambitious solar agenda. So, in order to undercut his opponent's strength, Paterson really has no choice but to double down and announce a world-class solar program for the state. It's pretty much his only chance to be successful.

Lemonade!

The dangers of funding new coal-fired plants

Indeed. This paper (PDF) on the risks of investing in new coal-fired power plants is worth reading.
