Peak Moment #172: The pee and poo show

by

Laura Allen gives an intimate tour of a home-built composting toilet in her Bay Area urban home. The nitrogen-rich composted “humanure” is used to fertilize the lush edible-food garden, and doesn’t waste precious drinking water like flush toilets. The co-founder of Greywater Action shows the throne-like toilet compartment whose distinctive feature is a urine diverter. Pee and poop are collected in separate containers beneath the toilet, and are accessed outside the house. Sterile pee is watered in at the base of plants, while poop is collected in barrels and aged for a year or more until it has composted fully. What a way to go!

Deepwater Horizon Could Result in 2nd Largest Oil Spill in History

by

Sometime within the next two weeks the free-flowing Deepwater Horizon well could surpass the second largest oil spill in history. Indeed, if we assume the highest independently measured estimates of the leak’s flow rate, Deepwater Horizon may have already released 84% of the total petroleum that was dumped into the Gulf of Mexico by the Ixtoc I, a similar rig blow-out that occurred in 1979.

Review: The Biochar Debate by James Bruges

by

It’s called biochar, and if you believe its most ardent supporters, then this unassuming, fine black powder is a vital tool in the solutions to some of humanity’s most urgent ecological threats, including climate change, peak oil, soil degradation and water pollution due to agrochemicals. However, if you side with biochar’s staunch opponents, then it seems like a fledgling, poorly understood technology with real risks, including the displacement of entire communities and the serious jeopardizing of world food security and biodiversity. Which view is correct?

Totnes Energy Descent Action Plan website launched today!!

by

It gives me the greatest pleasure this morning to launch the Totnes Energy Descent Action Plan website. The site makes the full version of the UK’s first EDAP freely available, invites comments and discussion, and will act as a dynamic portal for people to discuss the Plan and reshape subsequent revisions.

Urban resilience for dummies: Part 2

by

Last post I covered some guiding principles for urban resilience planning in the face of climate change and diminishing resources (especially fresh water and oil). Considering these guidelines, what aspect of U.S. metro development stands out as the most ill-advised and risky? Short answer: exurban sprawl.

Entropy revisited

by

One way of looking at our current set of predicaments is that we’ve been on a binge, consuming energy considerably faster than it can be captured and stored by Earth’s ecosystems. While fossil fuels once appeared limitless (and still do to deniers of peak oil), and though we’re literally bathed in energy (in the form of sunlight), the disappearance of the fossil-fuel storehouse accumulated over millions of years isn’t something that can be replaced with anything nearly as convenient as fossil fuels.

A short history of peak oil preparation

by

Frankly, when I first learned about peak oil, I was a bit freaked out. But after time, a little too much wine, a lot of research, and some productive action, I recovered, and went on to slowly change my attitude, expectations, and lifestyle to accommodate a radically different reality from the one I previously knew.
