Insight and inspiration in turbulent times.
How fast do we need to transition off of fossil fuels? What industrial capacity is available today for different alternative energy technologies and what is likely to be available in the future? What might we do if we can’t replace fossil fuels with alternatives fast enough, and what might the consequences be? I finally got around to re-doing these calculations, and wanted to go through the numbers.
At the intersection of global energy depletion and concerns about human impact on the environment lie some serious and oft overlooked issues. Largely gone from our public discourse is the idea that oil is infinite. It is now accepted, even to previous staunch cornucopians, that increasing, or even maintaining oil production will come only at higher costs. The new response to the energy/environmental crisis is to transition to a green economy, replacing our declining stocks of fossil sunlight with new technologies able to harness our current sunlight in its various forms. That these renewable technologies are available, viable and becoming more popular is not in question – however, whether these low carbon strategies can combine with now more expensive fossil fuels to maintain a growth trajectory for both the developed and developing worlds is another question entirely.
Most people who follow renewable energy have heard of biogas by now, yet the origins and uses of biogas remain mysterious to many.
Daunted by high up-front costs, U.S. homeowners continue to shy away from residential solar power systems, even as utility-scale solar projects are taking off. But with do-it-yourself kits and other innovative installation approaches now on the market, residential solar is having modest growth.

In this post, we’ll put a physical, comprehendible scale on the amount of energy typical Americans have used in their lifetimes. No judgment: just the numbers.
Was I surprised that last issue’s column, Can Renewables Outshine Fossil Fuels?, elicited a strong reaction, with written responses of support and derision? Not at all. It’s an issue that continues to divide the environmental community, and one which keeps us from moving forward as quickly as possible to conserve resources and relocalize as an era of cheap, concentrated, easy-to-get energy comes to an end.

Frequent guest Sharon Astyk declared a “riot for austerity” in 2007, which isn’t a riot at all. She led people from around the world in a voluntary effort to reduce their resource use by 90%. She is now starting up the “riot” again, and she invites you to join her in saving resources, saving money, and–perhaps surprisingly–having fun.
Peter Adamczyk, Energy Finance and Development Manager at Vermont Energy Investment Corporation (VEIC) talks about how the state’s newly revised PACE program can help towns help their home owners save money through energy efficiency and renewables.
As we look to transition away from fossil fuels, solar and wind are attractive options. Key factors making them compelling are: the inexhaustibility of the source with use (i.e., renewable); their low carbon footprint; and the independence that small-scale distribution can foster (I’ll never put a nuclear plant on my roof, even if it would make me the coolest physicist ever!).
Vigilante, klan, family and private justice, all are the path to barbarism today just as surely as they were when Aeschylus wrote the Oresteia. I will stand on the side of civilization for as long as I am able. The only alternative I see is what philosopher Thomas Hobbes called “a war of all against all.”
An eleventh hour political deal on the US debt crisis this week turned out to be just a stepping stone in the ongoing economic and fiscal crisis. By Thursday markets were plunging again on fears that Italy or Spain may default, and on the growing anticipation that the US may be returning to recession after Q1 GDP growth numbers were revised down from 1.9% to 0.4%.
