Science boring? Teach it through Permaculture!
Unfortunately, ecological literacy is not nurtured in most schools. At the same time, many science courses are taught in ways that turn too many students off to science.

No miracles in science: The story of the “energy catalyzer”
A few weeks ago some readers asked me to comment on an invention devised by two Italians, Andrea Rossi and Sergio Focardi. We are talking about the device known as “E-Cat” (Energy Catalyzer) which is supposed to produce energy from nickel, water and an unrevealed catalyzer…if the device were really to produce a significant amount of energy from a low temperature nuclear reaction, we would be facing an energy revolution; all the troubles with Peak Oil will be over and even we will have at hand a magnificent economic stimulus. There is only one problem: the E-Cat cannot be what it is claimed to be. Apart from contradicting all known physics developed up to now, the promoters have never been able to demonstrate that nuclear reactions take place inside the device, and not even that it can produce useful energy.

A reality check on oil supply for Newt Gingrich
During the CNN Republican presidential debate Tuesday, November 23, Newt Gingrich made statements about U.S. potential oil supply that reveal either total ignorance of energy or supremely dangerous demagoguery. He stated that the United States could discover and produce enough oil in 2012 to cause a worldwide oil price collapse.
The Energy Return on Investment threshold
Hall and Day (2009) report that the Energy Return on Energy Invest (EROI) for coal might be as high as 80 and that for hydropower, EROI is 40. Does this mean that coal is twice as ‘good’ as hydro? The answer is no, and in this post I will discuss how this relates to the idea of an EROI Threshold
The upcoming transition away from a fossil-fuel based society: David Holmgren talks strategy
How do we move away from a fossil-fuel based society? David Holmgren, ecological design engineer and co-originator of the term “Permaculture” discusses this very question.
Don’t go back to school: An interview with author Kio Stark
For college graduates in their 20’s or 30’s facing few job prospects and excessive student debt, graduate school can seem a promising way to sit out the recession. It’s far from a sure bet, though: there’s no guarantee of future employment, it only adds to the mounting debt post-undergrads face, and it consumes time and resources that could be better devoted to making things. But there are alternatives. Don’t Go Back To School is a project by author, NYU instructor, and Yale graduate school dropout Kio Stark exploring other ways to facilitate post-undergrad learning.
Guidelines for Transition book groups and study circles in general
The following guidelines are a great way to set the tone for any book group or study circle. We typically read them together at the first or second meeting of a group.
They were originally written for the Transition Handbook Discussion Course.
What we are for
Every activist engaged in combating human-caused climate change or specific elements of the current energy economy knows that the work is primarily oppositional. It could hardly be otherwise; for citizens who care about ecological integrity, a sustainable economy, and the health of nature and people, there is plenty to oppose…
These and many other fights against destructive energy projects are crucial, but they can be draining and tend to focus the conversation in negative terms. Sometimes it’s useful to reframe the discourse about ecological limits and economic restructuring in positive terms, that is, about what we’re for…
Home-grown food in schools for a green economy
As next June’s Rio+20 summit on sustainable development approaches, discussions about how to effectively establish a green economy are surging. But as a recent conference of the United Nations Institute for Social Development emphasized, the green economy is not simply about the economy and environment. Rather, it requires a deeper restructuring of economic and social processes including people’s relationships with food and agriculture.

Cob Cottage Company: Complete permaculture site
Ianto Evans and Linda Smiley at The Cob Cottage Company, in Coquille, Oregon, have created probably the most complete permaculture site in the country. Permaculture sites, including our own, generally emphasize plants, animals and earthworks and ignore building your own home. I am beginning to see that one cannot have permaculture without building your own comfortable dwelling from the materials onsite.
