Even if he was to restart that project, it's not a quick fix, it's a start over at this point. That's the problem with the shut down plants and plans, they take time to get going if you want them later. Personally, I think it'd be great if we could bring online some nuclear plants to help even power demand away from oil but they take forever to bring back online or build, same with any other generator plant. Pipelines take a long time to build too, a bit faster is increasing output from existing oil fields but generally that is a short-term fix and can hurt field profitability. Getting oil already on the market you currently aren't getting is something you can do with a turn around of weeks, not months or years.
But to be clear, I don't have a problem with buying oil from whomever is offering it cheaper than we can make it. It's a limited and vital economic resource, we should keep reserves for real emergencies. We just should not be so reliant upon it nor foreign markets for sourcing it.
