The overburden: Review of “The Last Mountain”

by

The film The Last Mountain has it all: a human story of ordinary citizens fighting a soulless and unaccountable coal corporation; an urgency as the last mountain in the Coal River Valley is eyed by Big Coal for surface mining; a history and context for the people’s claim to the rights of the commons; activism in the form of petitioning the government as well as civil disobedience; the role of business, profit, labor and economy as labor power is eroded and corporate profits soar; the eco-system, heritage, and culture of the region; and a new way forward proposed by the people themselves. It’s the best documentary I’ve seen on mountain top removal. But really, it’s about so much more and has come together perfectly as a gestalt, a meme for our times.

The Last Mountain, June 2011, 95 minutes, Dada Films, Directed by Bill Haney.

Peak Oil keynote by Randy Udall and sustainability conference call for participants

by

Randy Udall’s humorous and poignant presentation on peak oil was published today, recorded at the Local Future conference. Local Future invites visionaries, activists, and leaders to apply to the 2011 International Conference on Sustainability, Transition and Culture Change: Vision, Action, Leadership. Confirmed speakers include Nicole Foss, Dr. Steve Keen, T.S. Bennett, Sally Erickson, Guy McPherson, Jan Lundberg, Gregory Greene, Kurt Cobb, Stephanie Mills and Aaron Wissner.

Don’t be a PV efficiency snob

by

A common question I get when discussing solar photovoltaic (PV) power is: “What is the typical efficiency for panels now?” When I answer that mass-market polycrystalline panels are typically about 15–16%, I often see the questioner’s nose wrinkle, followed by dismissive mumbling that 15% is still too low, and maybe they’ll wait for higher numbers before personally pursuing solar. By the end of this post, you will understand why this response is annoying to me. At 15%, we’re in great shape: it’s plenty good for our needs.

Review: The Global Warming Reader, edited and introduced by Bill McKibben

by

Bill McKibben’s latest book is a well-chosen and arranged collection of climate-related writings by the likes of James Hansen, Al Gore and George Monbiot, which McKibben edits and introduces. Significantly, the book contains writings by Inhofe and his ilk as well, the better to understand “the lines of attack climate deniers have used over and over,” in McKibben’s words,

IEO 2011: a misleadingly optimistic energy forecast by the EIA

by

The EIA published International Energy Outlook 2011 (IEO 2011) on September 19, showing energy projections to 2035. One summary stated, “Global Energy Use to Jump 53%, largely driven by strong demand from places like India and China.” It seems to me that this estimate is misleadingly high. The EIA is placing too much emphasis on what demand would be, if the price were low enough. In fact, oil, natural gas, and coal are all getting more difficult (and expensive) to extract.

Got storage? How hard can it be?

by

Energy storage becomes more important as we transition away from fossil fuels—already its own energy storage medium—to more intermittent sources. But besides batteries—which offer a limited number of cycles and for some types require monthly maintenance—what other non-fossil in-home energy storage alternatives might we consider, and how much energy might we expect to store in each case? We will look at gravitational storage, flywheels, compressed air, and hydrogen fuel cells as possible options. Some might even cost less than $100,000 to implement in your home.

A guide for the perplexed energy policymaker

by

If you are an energy policymaker (or layperson interested in energy) and you are NOT perplexed by the last decade, read no further. You have little to gain from what I write below. However, if you are a perplexed energy policymaker (or perplexed layperson interested in energy), please continue and learn why poor quality data, lack of transparency, broad uncertainty and flawed thinking about risk have made it difficult for many experts and the public alike to think sensibly about our energy future.

Peak oil, peak debt, and the concentration of power

by

The transition before us is not merely a transition in fuel types. It is also a transition in the whole energy infrastructure, both physical and psychological; a transition away from big power plants, distribution lines, and metered consumers; away from capital-intensive drilling, refining, distribution, and consumer fueling stations. More broadly, it is a transition away from centralization, concentration, and all the social institutions that go along with it.

Garbage in, garbage out

by

How many times have you heard it: if we could tap into the energy embedded in our copious waste streams, we could usher in a new era of energy independence—freeing ourselves of the need to support oppressive regimes who happen to sit atop the bulk of the oil reserves in the world. In fact, these sorts of claims are abundant enough to give the impression that we have a cornucopia of fresh (and sometimes not so fresh) energy solutions to pursue if we got really serious. This is a hasty and dangerous conclusion, so in this case, waste makes haste.
