What’s up with solar silicon?

... how come solar power may be stymied by a worldwide shortfall in key ingredient poly-crystalline silicon? Despite the growing momentum for alternative power generation, the Financial Times quotes analysts citing "unsustainable" price increases of 500% over 2004 levels in some "isolated" cases.

Global production of solar batteries grew by 47 per cent by volume during 2005, and the pace is believed to have quickened in 2006. One industry estimate suggests that between 2007 and 2009, the global polysilicon supply shortage will be about 9,000 tons a year, or about a fifth of current worldwide capacity.

So much for those reassuring supply and demand lessons in ECON 101.

Can Thompson become president?

I never got around to posting on this last week, but it seems Bush's old Health and Human Services Secretary Tommy Thompson is getting into the presidential race. The enterprise is already somewhat of a laughingstock in political circles, but what's remarkable to me is that Thompson seems to think he has a chance almost purely based on his long-standing support for and knowledge about ethanol subsidies -- oops, did I say "ethanol subsidies"? I mean energy policy.

Perhaps ethanol subsidies are the road to serious energy policy. But then again, perhaps "energy policy" is just a road to expanded ethanol subsidies. Which do you think it is? Leave predictions in comments.

Something you need to know

The DVD of An Inconvenient Truth is released tomorrow.

Speaking of which, it's entirely possible that AIT will win the 2007 Oscar for Best Documentary. Wouldn't that be something.

Take bets on the long future

Much of environmentalism is about long-term thinking. If you are looking for a meta-narrative, I'd say most people who define themselves as environmentalists are motivated by the desire to see something they love -- clean air, beautiful places, whales, or whathaveyou -- stick around a bit longer.

That's why I think the Long Now Foundation, dedicated to the promotion of long-term thinking, is one of the coolest organizations around.

Sadly, it’s behind a paid subscription wall

Over on New York Times $elect, Steven Johnson -- author of Everything Bad Is Good for You and the just-released The Ghost Map -- is writing a blog called "Urban Planet":

Over the next month, I'll explore the many facets of our urban planet and its future, drawing upon the themes that were visible, in embryo, 150 years ago in the streets of London: the peril and promise of density, local knowledge, the importance of public health systems, and the strength of neighborhoods. I look forward to hearing -- and responding to -- your own stories and reflections on urban life.

Too bad only a tiny fraction of you can afford to read it.

Rail freight is more efficient than truck freight

So far the efficiency examples we've discussed have been glamorous new technology -- electric cars, next-gen light rail. But what may be the oldest mass industrial technology in the U.S. also has huge potential for saving energy: freight trains.

I couldn’t do it

While I was wandering around on YouTube I stumbled across a segment from CNBC featuring Ana Unruh Cohen, Director of Environmental Policy at the Center for American Progress and periodic Gristmill contributor, squaring off with Ben Lieberman from the Heritage Foundation. The subject was possible changes in energy policy under the new Democratic Congress. Watch it:

Is Western time on the outs?

"The clearest way into the Universe is through a forest wilderness," wrote John Muir (in a posthumous collection of his notes called John of the Mountains).

Yes, but why? Why does a wild forest take us into the universe more surely than the open sea? Or a vast metropolis teeming with people?

This month in Orion, critic and novelist John Berger takes a crack at that question in an essay called "Between Forests" (not online, unfortunately). Berger takes the forest photographs of Czech photographer Jitka Hanzlová as a point of departure. A glance at one of Hanzlová's mysterious photographs from her Forest series gets across Berger's essential point -- they have been taken "from the inside" of the forest. He writes:

Brace yourself

Discover magazine deems Silent Spring the 16th greatest science book ever published. Brace yourself for a flood of misinformed invective from the "DDT rulez and enviros kill African babies" crowd (about whom Tim Lambert is the authoritative source).

Also of note is No. 25: Gaia, by James Lovelock, who has recently sold his soul to the nuclear lobby.

Cause it’s nasty

As the Japanese prepare to herd thousands of dolphins into coves and stab them with spears and bash them with clubs until the sea is bright red with blood, many groups, including environmentalists, are uniting to oppose the slaughter.
