From the Guardian:
Speculation that government ministers are far more concerned about a future supply crunch than they have admitted has been fuelled by the revelation that they are canvassing views from industry and the scientific community about "peak oil".
The Department of Energy and Climate Change (DECC) is also refusing to hand over policy documents about "peak oil" – the point at which oil production reaches its maximum and then declines – under the Freedom of Information (FoI) Act, despite releasing others in which it admits "secrecy around the topic is probably not good".
Experts say they have received a letter from David Mackay, chief scientific adviser to the DECC, asking for information and advice on peak oil amid a growing campaign from industrialists such as Sir Richard Branson for the government to put contingency plans in place to deal with any future crisis.
… documents obtained under the FoI Act seen by the Observer show that a "peak oil workshop" brought together staff from the DECC, the Bank of England and Ministry of Defence among others to discuss the issue.

an internal IEA source said: "Many inside the organisation believe that maintaining oil supplies at even 90m to 95m barrels a day would be impossible, but there are fears that panic could spread on the financial markets if the figures were brought down further. And the Americans fear the end of oil supremacy because it would threaten their power over access to oil resources."
