AdamW said:Iraq, 142 years left
how old were theese stats?
extraction rates in iraq were low until recently due to trade sanctions (and probablly still are due to the war aftermath)
the saudis
i don't think we get much of our leccy from oil anyhow the problem with an oil shortage would be transport fuel
almost all currently used transport fuels are crude oil based
the saudis are extracting their massive reserves very slowly partly to keep oil at a high price and partly so they have reseves when oil becomes really valuable
russia and china on the other hand want all the oil money they can get
the usa reserves were huge but were heavilly tapped and have run very low
i don't think the uk ever really had much oil just a little in the north sea
accessibility also has a lot to do with it, many countries have lots of oil that is accessible only at great cost and is not currently economically viable to drill
