The UK government has been forced to release a 2009 analysis of "peak oil" and its implications.

I recommend it. You'll need PowerPoint.

Unfortunately, The Guardian's article on the release is considerably less reasoned than the report itself.

For the record, I've consistently said that 1) oil prices are more important than any resource availability in this analysis, and that 2) climate change is the real energy problem, since although we may be able to find considerable addition all reserves particularly of unconventional hydrocarbons like tar sands or natural gas, we may not wish to actually use them, and add to what are already considerable problems with extreme weather.

And I just said it again, didn't I?
