Course Review (or why Daniel Yergin needs to do his homework)

by

Recently I’ve been getting emails from folks who had previously read an article or two on Peak Oil and found the evidence convincing—but who have more recently encountered a piece or two by Daniel Yergin (or another writer following the same train of thought). Their new line of reasoning goes like this:…Just as “fracking” shale gas has been a “game changer” for the natural gas industry, new technologies for accessing tar sands, oil shale, and shale oil…will change the oil game…Now, every element of that argument has already been dealt with at length in the Energy Realist literature. But occasionally a review of previous course material is called for. So here we go…

Trouble in the algae lab for Craig Venter and Exxon

by

A much-trumpeted partnership of one of today’s most celebrated scientists and the world’s largest publicly traded oil company seems stalled in its aim of creating mass-market biofuel from algae, and may require a new agreement to go forward. The disappointment experienced thus far by scientist J. Craig Venter and ExxonMobil is notable not only because of their stature, but that many experts think that, at least in the medium term, algae is the sole realistically commercial source of biofuel that can significantly reduce U.S. and global oil demand.

Architectural myopia: designing for industry, not people

by

Have you ever looked at a bizarre building design and wondered, “what were the architects thinking?” Have you looked at a supposedly “ecological” industrial-looking building, and questioned how it could be truly ecological? Or have you simply felt frustrated by a building that made you uncomfortable, or felt anger when a beautiful old building was razed and replaced with a contemporary eyesore? You might be forgiven for thinking “these architects must be blind!” New research shows that in a real sense, you might actually be right.

The Hubbert hurdle: revisiting the Fermi Paradox

by

We have a well known problem called the “Fermi Paradox”. If all those extra-terrestrial civilizations exist, then could they develop interstellar travel? If there are so many of them, why aren’t they here?

Tim O’Reilly may have been the first to note, in 2008, that the Hubbert curve may be relevant for the Fermi paradox. Because of the non linearity of the curve, no matter what resources are being used, a civilization literally “flares up” and then subsides, being able to maintain the highest level of energy production only for a very short time. This phenomenon that we might call “The Hubbert Hurdle” may be very general and make industrial civilizations in the galaxy to be very short-lived.

Energy storage – flywheel

by

This piece resulted from a challenge within the staff to write a collaborative post on emerging energy storage technologies. I left Chemistry back in high-school but one technology that for long has fascinated me lead me to volunteer to the project: the flywheel. It seemed a good justification to study why these ancient mechanisms haven’t lost of the industry.

ODAC Newsletter – Sep 30

by

The debt crisis and the war in Libya continued their push and pull on the oil price this week with the outlook currently weakening over fears of a Eurozone recession. Despite this Brent continues to trade at over $100/barrel – around double the price at which any previous economic recovery has occurred. The rising cost of energy is playing out in a number of ways…

As the earth turns: Going global with perennial polyculture agriculture

by

Wes Jackson believes that shifting from fragile annual monocultures to more hearty perennial grains grown in a mixture of plants (polycultures) is the key to a truly sustainable agriculture. Instead of a brittle industrial agriculture dependent on fossil fuels, Jackson’s research team is working to build a resilient agriculture modeled on natural ecosystems.

With the health of our soils and our own bodies at stake, Jackson says, we can’t afford to assume old approaches can cope with coming crises. Because humans like to resolve ambiguity, we reward researchers who appear to do that within existing systems — such research may be right but irrelevant, if the real problem is at the level of the whole system. Solving individual problems within a system that can’t be sustained actually creates problems.

A time of catastrophe, a time for education

The Fukushima story is one that will emerge for months and years to come; the worst is behind us, but there are long-term problems that still must be addressed. In our Fukushima Issue, six authors provide a snapshot of where Japan and the international community stand six months on.
