Qu: what country has got a potential oil reserve of 6 times that of Saudi Arabia.
A: Canada. Locked up in the Athabasca Oil sands in Alberta

So phew! Peak Oil concerns over then is it? - enough to go all round? not exactly if you read this article. A Part from the fact that they can only access 10% of it, its extraction is having a huge and disastrous environmental impact. Apart from ripping apart a huge landscape, oil sands need a lot of energy to be processed: 1 barrel of natural gas is used to produce two of crude. So whilst only running at a few percent of its potential capacity Athabasca oil sands will already soon be Canada's biggest contributor to global warming; nearly as much as the whole of Denmark. This is not an acceptable alternative to the sweet light crude from the Gulf, that has already had a bad enough impact on the planet, surely this madness to develop this resource.
