Insight and inspiration in turbulent times.
A look at tidal power, which is virtually inexhaustible on relevant timescales, is less intermittent than solar/wind (although still variable), and uses old-hat technology to make electricity. Is it “abundant,” “useful,” or “a waste of time”?
The opportunity to pull Michigan out of its economic slump and deal with climate change is right in front of us. But leaders are dithering.
OPEC head Abdullah El-Badri warned European leaders on Wednesday against imposing sanctions on Iranian oil, stating that the 865,000 barrels a day which goes mostly to Southern Europe would be difficult to replace. Global supply is already tight and oil prices remain stubbornly high despite the chronic Euro-crisis…
One of the perennial themes of peak oil discussion over the last decade or so has been what the world will look like once the age of cheap abundant energy comes to a close. While the arguments are ongoing, the answer may already have arrived. With a tip of the hat to green economist Herman Daly, the Archdruid explains.
Yesterday I received an email and a telephone call from Radio China International. They inquired if I would be willing to answer a few questions on the occasion of the 20th World Petroleum Congress in Doha, Qatar. Every third year the world’s oil producers gather for a large congress. For the first time they have now gathered in the Middle East. The interview with Radio China International has now been completed and it is interesting to look at the questions that they wanted to discuss…They sent me written copies of the questions that they wanted to discuss so let’s look at what worries and interests China.
-Biomass is the next biofuel ‘land grab’ on tropical forests, warn campaigners
-Climate Committee: Biomass has “no role” in electricity production without CCS
-CLIMATE CHANGE: Biofuels Are Not the Solution
-Navy’s Big Biofuel Bet: 450,000 Gallons at 4 Times the Price of Oil
-Aviation could switch to low-carbon fuel ‘sooner than thought’
Having written extensively on occultism and the esoteric, and himself an adept in ritual magic, John Michael Greer is an eager student of the unexplained. Yet he’s also a sharp observer of the unexamined assumptions that people make about the physical world around them, and how these assumptions have helped land the world in its present crisis. One common presupposition is that nature is independent of the world of human economics, and thus can be treated as a disposable resource. An environmentalist and a devout follower of the druid path, Greer knows better, and he’s written several books seeking to dispel this mistaken dismissal of nature.
For me, the most delightful turn of events in the ultimate nerd-song”Particle Man” by They Might Be Giants, is that after introducing (in order of complexity) particle-man, triangle-man, universe-man, and person-man—and learning that triangle-man naturally beats particle-man in a match up—we pit person-man against triangle-man to discover that triangle wins—again. In this post, we’ll pit solar against wind and see who wins.
If there is one unshakable belief in America today it’s that the U.S. economy can and must continue to grow. That’s why the messages delivered in November in Washington D.C. at a gathering of oil geologists, scientists, economists and others challenging that core belief went largely unheeded in the nation’s capital. The approximately 300 people who attended the 7th Annual Conference of the Association for the Study of Peak Oil–USA (ASPO-USA) in the shadow of the U.S. Capitol were told that economic growth is no longer possible as oil production flattens and declines, that U.S. energy independence is impossible and that domestic shale gas will fall far short of fueling American prosperity even while polluting the nation’s vital aquifers.

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
