You are right, dollpartz. 2030 to 2035 are the numbers that are quoted as when US will be self sufficient. However, Scotiabank's commodity analyst Patricia Mohr has the following to say:
"........... The U.S. - which currently imports about 20 per cent of its energy needs - will be energy self-sufficient by 2035. But don't expect to wait that long to feel the impact of such a dramatic sea-change in global energy supply, Mohr said.
"The U.S. is reducing its reliance on imports quite phenomenally, and if we don't build pipelines like Northern Gateway, or the expansion of the Trans Mountain pipeline into Burnaby, I think we are going to stunt the growth of the oil industry in Western Canada. I think this will become self-evident very quickly - in about three years' time."
Investors in Canadian oil stocks are likely to be the first to feel the impact, she said.
"You are going to find shortly that this bears on the actual return on shareholders' equity for Canadian oil stocks. This is not something that has airy-fairy implications. It is quite real," she said. ..............."
This is only an analysis from one source and one can take it with a grain of salt. However, the graph from ‘Saudi Dakota’ showing the exponential climb of N Dakota Bakken oil production does seem to jive somewhat with what she is saying regarding the short time frame of Canada feeling the effect without the extra oil pipelines going west. The expansion of the Trans-Mountaint would be a lot easier to get approved. For the Northern Gateway, I don't think I would even want to comment on it as it's a hornet's nest.
