Peak oil: 'Nothing to worry about' – but Labour knew the real facts | George Monbiot | Environment | guardian.co.uk: 

"In public, the last government shrugged off the prospect of peak oil. In private, we know now that it had a different view. A powerpoint presentation released at last by the Department of Energy and Climate Change, in response to freedom of information (FoI) requests by the indefatigable Lionel Badal, shows that in 2007 the Labour government spent six months secretly gaming the likely impacts of declining global oil supplies. The results were not pretty.

The officials who conducted the assessment found that 'it is not possible to predict with any accuracy exactly when or why oil production will peak'. They believed that 'a permanent decline in global oil production [ie, peak oil] is unlikely to take place before 2020. However, if it were to happen, the consequences for economic prosperity and security are likely to be serious'. Among these consequences were:

• Impacts on UK security of oil supply

• Disruption of the UK economy especially the transport sector

• Possible geopolitical implications.
