Think thin

For Nanosolar, the future is municipal solar power plants

The following post is by Earl Killian, guest blogger at Climate Progress. ----- Traditional photovoltaic (PV) is typically installed on rooftops and competes with retail electricity. Over 40 percent of the cost of a system can be in the installation, which must be customized to every rooftop. So technologies that dramatically lower PV cost end up having a less dramatic impact on total residential system cost. So it is natural that the next generation technologies, such as thin films of copper indium gallium selenide (CIGS) printed as ink on conductive substrates, need to look at non-rooftop applications, where the installation of a large solar farm is fairly turnkey. Nanosolar, a thin-film PV startup, has just announced their vision in their blog and newsletter. They see the best fit for solar being municipal solar plants of 2-10 MW in size and suggest such plants can be done in 12 months, providing a significant advantage over coal or nuclear. Martin Roscheisen, Nanosolar's CEO, writes:

Pollan envy

The Pennsyltucky perspective

No difference between McCain and Dems on climate

I got home yesterday from canvassing for Barack Obama in the outskirts of Harrisburg, Penn. and found last week's edition of The Patriot-News (whose politics reporter, Brett Lieberman, describes the state as "Pennsyltucky" for its unique mix of urban, industrial, and backwoods), including a "Find Your Match" voter guide with a chart that's supposed to help people figure out which candidate is closer to them on key policies. Here's what the chart said about Obama, Clinton, and McCain on global warming: Clinton: $150 billion, 10-year energy package for new fuel sources; backed stringent caps on greenhouse-gas emissions. Obama: $150 billion, 10-year program for "climate friendly" energy supplies, favors stringent caps on greenhouse-gas emissions. McCain: Led Senate effort to cap greenhouse-gas emissions; favors tougher fuel efficiency.

Fighting Goliath: Texas Coal Wars

New Sundance doc tells the story of the TXU coal fight in Texas

I finally got around to watching my preview copy of Fighting Goliath: Texas Coal Wars, the new short documentary from Robert Redford’s Sundance outfit. It’s about the battle over the 12 coal plants proposed for …

Me, worry?

Most Americans don’t believe global warming will pose a threat to them

A new series of Pew polls shows public concern for climate change is out of sync with the science:

Let's dump 'Earth' Day

Environment Day? Triage Day? The holiday needs more than a new name

Affection for our planet is misdirected and unrequited. We need to focus on saving ourselves. I have a new piece in Salon: "Let's dump 'Earth' Day." It is supposed to be mostly humorous. Or mostly serious. Anyway, the subject of renaming Earth Day has been on my mind for a while. An excerpt:

Please, sir, I want some GMOs

Worldwide resistance to GMOs dwindle as food bills rise

For a while now, I’ve been cautioning people that surging prices for industrial food don’t necessarily “level the playing field” for sustainably produced fare. In fact, the few giant companies that dominate the global food …
