At the Denver ASPO conference, I had the good fortune to meet Dr. Albert Bartlett. Afterward, Dr. Bartlett e-mailed me some material he had written over the years. The "Laws of Sustainability" were included in this material. They are part of Al Bartlett's contribution to the anthology The Future of Sustainability by Marco Keiner, published in 2006. The document by Dr. Bartlett from which these were excerpted can be found here.
LAWS OF SUSTAINABILITY
The Laws that follow are offered to define the term "sustainability." In some cases these statements are accompanied by corollaries that are identified by capital letters. They all apply for populations and rates of consumption of goods and resources of the sizes and scales found in the world in 2005, and may not be applicable for small numbers of people or to groups in primitive tribal situations.
These Laws are believed to hold rigorously.
The list is but a single compilation, and hence may be incomplete. Readers are invited to communicate with the author in regard to items that should or should not be in this list.
First Law: Population growth and / or growth in the rates of consumption of resources cannot be sustained.

IAN: Well I do subscribe to the theory of peak oil. But again, I think the demand for oil is going to drop precipitously. Simply because no one’s gonna be working. Again if we use the idea that 45% of the U.S economy is going to be halted. That means essentially that the same kind of oil demand is the percentage dropping oil demand is also going to occur in the United States. And we are only picking on the United States because she has the largest economy in the world but we are all going be in be in the same boat.So the whole world economy is going to drop by that kind of percentage.
TRACE: But not necessarily a precipitous enough drop that we could see 90% of the earth’s population washed away in this winter because of unsustainability?
IAN: Well, you are not going to see that because, as you know, there is a significant part of the world’s population who basically do not have anything anyway. If we go into Africa, or huge parts of China, India, etc. even though they are emerging nations they still have a large percentage of the population that are extremely poor.

Note from the author (Dan Allen): As a high-school teacher, I wanted to give my thoroughly-industrial, suburban-NJ students a more detailed peek at their upcoming post-industrial future. I felt the need to challenge their prevailing mindsets regarding our resource-depletion predicament: the “shorter showers & change the light-bulbs” crowd, the “engineers will surely come to our rescue” folks, and the “problem? -- what problem?” people. This essay and the before/after comparison chart that follows are part of my ongoing (unsanctioned) attempts at doing so.

Kunstler: It's Time to Rebuild Our Passenger Railroad System
The world economic fiasco, which I call "The Long Emergency," may be speeding us into a future of permanent nostalgia in which anything that is not of the present time looks good.I say this to avert any accusations that I am trafficking in sentimentality where the subject of railroads is concerned. For the moment, any suggestion that a railroad revival in America might be a good thing is generally greeted as laughable for reasons ranging from the incompetence of Amtrak, to the sprawling layout of our suburbs, to our immense investment in cars, trucks and highways -- motoring culture now overshadowing all other aspects of our national identity.

Monday, November 2, Arthur Berman wrote in his blog:
Pressure from Petrohawk helps cancel World Oil column
In an act of extraordinary courage, a top Petrohawk executive threatened to cancel his free subscription to World Oil if the magazine continued to publish my column. Today, John Royall, President and CEO for Gulf Publishing, cancelled my November column.
I have accordingly resigned as contributing editor.
Heading Out (Dave Summers) and I have been talking about the issues Arthur Berman raises for quite a while now. Most recently, Dave wrote a post called Shale Gas Estimates Perhaps Optimistic - An Interesting and Worrying Talk at ASPO.
So what are the issues involved?

World Need for Oil Expected to Ease: International Energy Agency Says Conservation Efforts Will Trump Any Global Economic Recovery
The International Energy Agency next week will make a "substantial" downward revision to its long-term forecast for global oil demand, a person familiar with the matter said, marking the second year running the group has slashed its view of the world's thirst for oil.The forecast of slower growth in oil demand puts the IEA increasingly in a camp of contrarians bucking the popular view that crude demand will grow briskly in a postrecession world. That view holds that long-term demand will grow at a fast clip because of rising emerging-market wealth and consumption in places like China and India.
...A person familiar with the Paris-based IEA's plans said "demand-management policies" are having more impact than previously expected in the developed world, which accounts for about 55% of world oil consumption. The IEA outlook, a guidepost for industry trends, is scheduled to be released Nov. 10.
Fuel Economy Factors - Part 1: The Role of Aerodynamic "Drag"

This is a guest post from Will Stewart. Will is a systems engineer in the DC area and previously has written several guest posts on The Oil Drum, including a series on Passive Solar Design.
As oil production falls and volatile oil prices in concert with a struggling economy induce a pattern of demand suppression/destruction, mobility choices will narrow and Vehicle Miles Traveled (VMT) will decline. What should governments at all levels be proactively preparing for? What should individuals and their families be preparing for in advance? The choices are broad: at a high level, land use planners could refine cities into a series of compact, carfree urban districts interconnected with mass transit. For the existing built-out suburban and exurban communities, however, such choices are limited. Aside from telecommuting, transportation choices will increasingly include biking, carpooling/vanpooling, bus rapid transit, and other efficient means of transportation. Travel between cities and countries will also undergo a transformation, with air travel becoming less and less affordable.
This series will cover current and projected land-based vehicle energy efficiency and a high level overview of the factors that determine it, such as aerodynamic drag, weight, efficiency of motive force (e.g., engine, motor), rolling resistance, driver behavior, drivetrain losses, parasitic losses, environmental factors, Passenger Miles Traveled (PMT), etc. In this first article of the series, we will focus on energy losses associated with aerodynamic drag losses, or more succinctly, “drag”.

Today Daniel Yergin, author of the seminal oil industry tome ‘The Prize’, wrote in the Wall Street Journal that shale gas is a game changer for US energy. Those who follow natgas will have heard it all before: more advanced and affordable technology, mainly hydraulic fracturing or fracking, has opened up an abundant supply of gas that could satisfy US needs for many, many decades to come. Yergin’s point that this has happened with ‘no great fanfare,’ however, probably stands true for the average person who isn’t an avid follower of energy news.Shale gas not only promises to relieve the US of a potential energy security headache, but there’s the oft-quoted environmental angle, too: as a source of electricity, natural gas can give off 50 per less CO2 than coal, when burnt in the modern plants. It’s not just for the US, either: suggestions are that Europe and Asia might have huge supplies of shale gas, too (although Yergin notes that development of such resources could be some way off).
But there’s a persistent bunch of doubters about the shale gas story. The explosion in shale gas is new, and the horizontal wells that are being drilled furiously by Chesapeake are widely known to decline in output fairly rapidly after the first 12 months. This has led some respected resource watchers, including Matt Simmons, to voice scepticism that the shale gas is really about to revolutionise supply.
The Bakken Shale - Has it Moved the Oil Needle?

This is a post by Piccolo, a petroleum engineer working in the petroleum industry.
In April 2008, we published an initial assessment of the Bakken Shale and compared it to the USGS estimates of the resource: “The Bakken – How much will it help?” That piece covered production up to October 2007; the current article extends that analysis 18 months to March 2009. With this installment I would like to look at phases of development as they relate to geographical movement of the play, and discuss whether the Bakken is making an impact on total US production. In other words, has the Bakken moved the needle on US production?
