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,

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.

Energy infrastructure of the post-carbon future

by

The urban infrastructure of the post-carbon future will need to rediscover and utilize lost technologies and processes from history.

Integrated waste-to-energy combined heat and power systems can meet essential needs for food, clean water, public health and sufficient electrification for elevators and public transportation in a well-planned eco-city and provide a modest amount of energy for local light industry. When considering how much energy would be available, it would be misleading to look at total city energy use as planners do with today’s centralized utilities. Instead, it would be more helpful to examine how much energy you and your family could produce yourselves with a small, household anaerobic digester and gasifier and home combined heat and power system.

Review: Life Without Oil by Steve Hallett With John Wright

by

“Imagining a world without oil” describes in stark detail what might happen if one day the world decided to decommission all its oil tankers, rigs, pipelines and strategic reserves. The authors, environmental scientist Steve Hallett and journalist John Wright, expect that we’d initially see sky-high prices and long lines at pumps. After a few weeks, fuel wouldn’t be had at any price and even first-world citizens would struggle to stay fed and out of the elements. This is no Hollywood doomsday scenario—it’s a levelheaded extrapolation from current trends in the fast deteriorating world energy situation. [An essay prefiguring the book originally appeared in The Washington Post.]

Equal energy for all: Can we democratize the grid?

by

As long as communities still rely on centralized, fossil-fuel powered energy plants to generate power, democratization of the electrical grid will remain a dream. But the past 10 years have seen an exponential growth in the adoption of renewable energy alternatives, namely home solar and wind power, which presents an unprecedented opportunity for transformation.

Energy and water – the real blue-chips

by

Todays prices and costs provide a very bad basis for making investment decisions because they reflect temporary relative market scarcities rather than long-run underlying physical ones. The world needs to abandon money as its measure for determining energy and economic policy if it is to invest its scarcest, most limiting resources in the best possible way.
