Peak Oil

Hmmm. The Guardian online today picks up on a bit from the Observer suggesting that minister are more concerned about peak oil that they have hitherto let on. About time too! "Experts say they have received a letter from David Mackay, chief scientific adviser to the DECC, asking for information and advice on peak oil". DECC officials did not deny this but said it was a 'routine' enquiry. Why can't they just come out and say that peak oil is a concern? Later on in the article there's apparent official endorsement of the IEA's position that there is sufficient resource until 2030 as long as investment in new reserves is maintained. But 2030 is only 20 years away. Isn't this complacency rather worrying?
