Vision Prize is an expert poll on the nature of the climate risks we face, meant to demonstrate the degree of consensus (or the lack thereof) amongst those able to judge the evidence. It’s put together by Carnegie Mellon University. Will be interesting to see what the results look like…

Open Climate Science Course
The University of Chicago has created an Open Courseware style Climate Science 101, with videos of the lectures and self-assessment materials online. It’s aimed at non-science undergraduates. If you, or someone you know, want to get a little more in depth knowledge about climate science on their own time, it’s a great resource.
Coal Finance for Climate Activists
I’ve been in New York since Monday for a short workshop on the finances of the coal industry and coal burning utilities. It was put together under the auspices of the NYU Law School’s Institute for Policy Integrity. The audience was mostly grassroots campaigners from all over the country — people working to shut down coal mining and coal based power plants for environmental reasons, both climate related and more traditional pollution. The two day program included panels of utility specialists from rating agencies Moody’s and Fitch, Bruce Nilles from the Sierra Club’s Bloomberg funded Beyond Coal campaign, as well as financial analysts from UBS, Bloomberg New Energy and Jeffries. Tom Sanzillo, the former comptroller of the state of New York, gave us a run down on how to read a utility company’s 10-K. Several community leaders in successful fights to keep new coal plants from getting built told their stories too. All in all, it made for some strange bedfellows. It was great overall, and I think pretty much everyone learned something. Here’s what I remember learning.
Alex Steffen’s SXSW Eco Keynote
Alex Steffen gave one of the keynotes, at the first SXSW Eco Conference this fall, talking about good cities as the single best leverage point we have in reducing GHG emissions. It’s broadly the same collection of ideas as his forthcoming crowdfunded book Carbon Zero: A Short Tour of Your City’s Future. Looking forward to its eventual release.
Sustainable Energy Without the Hot Air
Sustainable Energy, without the Hot Air by David MacKay, is a book (available in its entirety online) looking at the sources of energy available, and the ways in which we use it today. There are lots of options, but any real discussion has to, at the very least, use numbers that add up.
Coal Exports a Bigger Threat Than Tar Sands
Eric de Place does some simple calculations, which demonstrate that the planned coal export terminals in the Pacific Northwest will be a larger climate catastrophe than the temporarily delayed Keystone XL pipeline, which would carry Alberta tar sands bitumen to the Gulf of Mexico for refining. A sobering reminder that in this conflict, we must win many battles consistently for many years to keep the atmosphere from being changed.
A Power Company President Ties His Future to Green Energy
Yale Environment 360 has an interview with the CEO of NRG Energy, a fossil fuel based, nationwide independent power producer (IPP) that sells their 22GW of generation into the wholesale market. He’s bullish on solar PV, much less so on wind. No mention of solar thermal. He believes storage will be vehicle batteries. Net metering policies and pricing will be key to broad adoption. Given the lack of forecast energy demand increase, he sees different sources of energy (esp. coal, gas, solar, wind) having to compete for market share for the first time. It’s important to note that as an IPP his position and incentives are much different from those of regulated utilities like Xcel, who certainly do not want to “keep [their] rates to [their] consumers down and get these electrons onto its grid at a very cheap price”. And I think regulated utilities still make up a large majority of electrical generation in the US.
Obama Delays Keystone XL Pipeline
The Obama Administration has delayed its decision on the Keystone XL Pipeline. I think this is a qualified victory for climate activists, and I think it’s incredible. A few months ago we hosted a cross-country caravan of Tar Sands Action protestors sleeping in our living room and carport on their way to DC to be arrested (along with Bill McKibben, James Hansen and more than a thousand other less well known folks), for protesting en masse in front of the White House. I thought it was a near-hopeless battle. Really, who knows what’s possible when we get our shit together?
Is Keystone XL Really Game over? | RealClimate
RealClimate looks at Hansen and McKibben’s statements that the Keystone XL is essentially “game over” for the climate. All that really matters in the big picture is the absolute amount of carbon we release. How fast or slow we do it is of little consequence, because the effects last on the order of 10,000 years. If we’re aiming for 2°C of warming, or 450ppm CO2, and we assume that all of the world’s conventional oil and natural gas reserves are going to get burnt because they’re just too convenient, then we’re left with another 260 gigatonnes (GT) of carbon that can be released cumulatively from other sources. The Athabasca oil sands in total contain 230 GT (close enough to call it game ending) but not all of that will be producible economically. Even if we decide to go ahead, only a fraction of that will end up in the atmosphere. The Gillette coalfield in Wyoming’s Powder River Basin on the other hand contains about 70 GT of carbon in total, maybe half of that eventually being exploitable. Globally there are only 2 large tar sands deposits (the other being in Venezuela), but there’s a pretty large amount of coal… something like 800 GT of carbon equivalent appears to be economically accessible, and that’s far more than enough to fry us. So the Keystone XL pipeline and the tar sands in general are certainly significant battles, unlocking vast amounts of carbon, but in isolation, they’re not enough to end us. But then of course, they don’t exist in isolation. Going ahead on these non-traditional fossil fuel projects means we at some level intend to just Burn It All.
Former Xcel CEO Dick Kelly would be fine with no more coal
Former Xcel CEO Dick Kelly would be fine with no more coal. Unfortunately, the regulatory environment that his former employer works within in Colorado, and the company’s need to protect a couple of billion dollars worth of undepreciated coal assets makes it very hard for them to move away from it.
