Commentary: When technical feasibility doesn’t matter

by

One of the hardest concepts for many Americans to absorb is this – that technical feasibility rests on a complex bed of other feasibilities and never stands alone. Thus, simply observing that it is technically possible to, say, create zero impact cities or to run our cars on corn waste does not usefully tell us whether we are going to do so or not. This historical reality stands in stark contrast to the perceptions that many of us have, which is that technology operates as a kind of vending machine into which one puts quarters and gets inevitable results.

Of hurricanes, hubris and hot water

by

This post is both my own experiences of living through Hurricane Irene on Sunday, 8/29/11, and a few thoughts about what is truly dangerous and what kills people in this type of storm. Most of the “news” clips are deaths from Hurricane Irene. These dramatic photos are all Hurricane Irene today, in Western MA (and one from Southern VT). I hope they give you sober reflection. Let’s be careful out there, those of us on the Eastern Seaboard of the USA. Even as the sun shines, most of the dangers of a hurricane happen AFTER the winds and rains die down.

Theater-states and the long count

by

“We tend to characterize every civilization in terms of “preclassic, classic, and postclassic,” but we might do better to think of it as “stable and expanding,” “unstable,” and “shrinking and reconsolidating.” Preclassic Maya agriculture was exceedingly diverse, with agroforestry, household garden plots, rotational field crops, chinampas and aquaponic systems, and perhaps also novel farming techniques we have yet to learn about. So was the postclassic.”

Review: Hand Made in Tasmania

by

What draws most antique lovers is not antiquity itself, I suspect, but craftsmanship, the hours of care and lifetime of skill imbued in the final product. A chair, a knife, or even a toy made before the energy needle often meant an investment of many hours of work by someone who had trained for years to master their craft. Such handiwork might last centuries – we have a desk two hundred years old, for example – and if the work breaks it can be repaired or the pieces replaced.

At the American Journal of Public Health, experts examine the risks posed by peak petroleum

by

The September issue of the American Journal of Public Health is now available online featuring 8 studies and articles by an interdisciplinary set of experts, each examining the health risks posed by peak petroleum and what can be done to mitigate and protect against the onset of a major spike in energy prices.

Why do so many people believe in the fantasy of infinite growth on a finite planet?

by

Each day it becomes more apparent that we are on a misguided mission. Pursuit of perpetual economic growth is not a winning proposition for a lasting prosperity. Building a bigger economy can make sense in some circumstances, but always aiming to build a bigger economy means taking an ever-bigger chunk out of the earth’s ecosystems and the life-support services they provide. Why, then, do so many people believe in the fantasy of infinite growth on a finite planet? Is it because we can’t come up with a better idea? Is it because the rich and powerful have trapped the rest of us in their web of conspiracy? Is it because people are hopelessly greedy and materialistic?

MPG for Electric Cars?

by

A typical efficient car in the U.S. market gets about 40 MPG (miles per gallon) running on gasoline. A hybrid car like the Prius typically gets 50–55 MPG. In a previous post, we looked at the physics that determines these numbers. As we see more and more plug-in hybrid or pure electric cars on the market, how do we characterize their mileage performance in comparison to gasoline cars? Do they get 100 MPG? Can they get to 200? What does it even mean to speak of MPG, when the “G” stands for gallons and a purely electric car does not ingest gallons? This post addresses these questions.

The debt bomb, net energy and ancient Greeks

by

The sooner we can admit that a large portion of the loans now outstanding will never be paid back in full and move on, the sooner we will be able to invest in the steps we need to prepare ourselves for a future marked by limits on resources. However, if no acknowledgement is forthcoming, then we are likely to face a long-term stagnation that will starve society of the capital it needs to make important investments in a more sustainable world.

The road to Europe: movements and democracy

by

Europe’s crisis is a crisis of democracy. The ‘democracy of the experts’ cannot deliver: representative democracy is incapable of channelling demands in the political system. More participatory and deliberative democracy is needed, as argued in Europe’s public spaces by the movements of ‘ indignados’.
