It’s worse than you think: plotting global hydrocarbon collapse

by

More than 90 per cent of the world’s energy comes from non-renewable sources – and its decline can be projected on a Hubbert bell chart. It’s just that we are more familiar with the concept of peak oil. After all, oil is the world’s largest source of energy, and the size and immediacy of the problem tends to overshadow debate on the remaining energy sources. But Hubbert’s model proves versatile, as the exploitation of any non-renewable resource – from oil to uranium – follows similar patterns.

Optimism versus reality in peak oil media battle

by

The optimists may have long been winning the peak oil media battle – as Matt Simmons observes – but we are beginning to see information coming out on the business pages that allows us to piece together a more balanced story. Right now, much of this focuses on everyone’s favourite cause for optimism, the oil sands…But do the facts support this rampant enthusiasm? I’d suggest not.

Deepshit Horizon: Earth Day began with a blow-out, will it end with one?

by

On January 28th, 1969 the Union Oil Company’s Platform A, located six miles from Santa Barbara, CA experienced a “blow-out.” Highly pressurized deposits of natural gas pushed upward against the newly bored well causing oil to leak from the pipe and casings…The blow-out was devastating. Ironically, and tragically, this year’s Earth Day celebrations coincided with another oil rig blow-out, this time offshore of Louisiana. Like other recent mining disasters, the explosion and sinking of the rig caused by a well blow-out has claimed the lives of at least eleven workers.

What is the Minimum EROI that a Sustainable Society Must Have? Part 2: The Economic Cost of Energy, EROI, and Surplus Energy

by

In real economies, energy comes from many sources – from imported and domestic sources of oil, coal and natural gas, as well as hydropower and nuclear, and from a little renewable energy – most of that as firewood but increasingly from wind etc. Most of these are cheaper per unit energy delivered than oil. So let’s look at what this real ratio of the cost of energy (from all sources, weighed by their importance) is relative to its benefits.

Entropy revisited

by

One way of looking at our current set of predicaments is that we’ve been on a binge, consuming energy considerably faster than it can be captured and stored by Earth’s ecosystems. While fossil fuels once appeared limitless (and still do to deniers of peak oil), and though we’re literally bathed in energy (in the form of sunlight), the disappearance of the fossil-fuel storehouse accumulated over millions of years isn’t something that can be replaced with anything nearly as convenient as fossil fuels.

A thousand barrels a second by Tertzakian (2007) (review)

by

Peter Tertzakian has a double education in geophysics and economics and is “Chief Energy Economist” at a Canadian energy investment company. His book “A Thousand Barrels a Second: The Coming Oil Breakpoint and Challenges facing an energy dependent world” was published in 2007, but was, based on the contents of the book, presumably written up around 2005.

Review: Why Your World Is About to Get a Whole Lot Smaller by Jeff Rubin

by

Jeff Rubin, former chief economist at Canadian investment bank CIBC World Markets, is not your typical economist. He gets peak oil…And now, in his bestselling book Why Your World Is About to Get a Whole Lot Smaller, he argues that oil prices, temporarily dampened by the deepest post-war recession on record, will soon be vaulted to new highs as the economy begins to recover, which in turn will thrust the world into yet another recession right on the heels of this one.
