One feature of this year’s ASPO conference that I most enjoyed was the contradiction amongst presentations. Marcio Mello gave an animated talk on Sunday night about the pre-salt formations off the coast of Brazil quoting that there are upwards of 500 billion barrels of oil available, an extravagant estimate that peak oilers are unused to hearing. Monday morning two talks on natural gas were juxtaposed in tone and content, one claiming that natural gas is the “American Treasure” and the other claiming that shale gas is marginally profitable, let alone a “treasure.”
Contradiction in this kind of academic setting magnifies the awareness of all involved by broadening the scope of the discussion.

Following the ASPO conference in Denver, the State University of New York - College of Environmental Science and Forestry will host the 2nd annual conference on Biophysical Economics. Joseph Tainter is this year's plenary speaker, and will discuss biophysical economics and the collapse of complex societies. Other speakers include Gail the Actuary and David Murphy from The Oil Drum, as well as the host, Dr. Charles Hall.

Cutler Cleveland of Boston University has reported that the EROI of oil and gas extraction in the U.S. has decreased from 100:1 in the 1930’s to 30:1 in the 1970’s to roughly 11:1 as of 2000 (Figure 1). But beyond the fact that society receives currently around 11 barrels of oil for every 1 barrel that it spends getting that oil, What does this mean?
