They could build a nuclear power plant to supply electricity for the tar sands extraction that could also hydrolyze water to get hydrogen to reduce the hydrocarbons and eliminate the need for natural gas. I tried to learn about this EROEI concept which on the surface sounds simple but the tables I saw say nothing about how they calculated it. It may be flawed due to erroneous assumptions. It's obvious that it takes more energy to produce a barrel of oil from tar sands than a Saudi light sweet field but it begs the question of how the tar sand companies can profit if they're buying 2 barrels of oil for every 3 they produce and have other expenses on top of that.

<The EROEI for tar sands and oil shale, probably the most promising stopgaps, is 1.5 and 1.35 whereas light sweet crude is around 30 so that's a twenty-fold price increase.> This is an erroneous statement. Just because the EROEI is 20 times less efficient does not mean that the energy derived from shale is 20 times more expensive. This board has taken a very dim view of the future lately. According to Ken Deffeyes coal can be turned into gasoline for about $1.75 per gallon and we have centuries of supply left at current usage and probably decades of supply left at stepped up usage. The world or industrialization is not going to end with peak oil. This board is starting to sound a lot like the Richard Heinburg interviews I've listened to.
