At the time Keystone was stopped, it was about 8 months from operation. That means, approximently, it would have been operational by September 2021.
You would have been receiving an additional 900,000 barrels/day for about 10 months so far.
Since it would the US first, the US would have had first dibs on it before it went on the world market.
Figure this out, if green energy works, why is Germany panicking about being cut off by Russia? They went whole hog into green energy. They should be laughing about $140/barrel oil.
I am not sure which of your statements is WRONG. In Comment #32 you state “three years to get the materials and equipment and at least as long to get thanpower (correction please) together. Had any of this pipeline even been build at the time Keystone was stopped? In this comment you say at the time Keystone was stopped (Feb. 2021) it would have been operational in 8 months. Yet in #32 you say to get the materials and equipment (which the company says it is now removing) would take 3 years, and then you say at least as long (another 3 year?) to get “thanpower” together. So maybe, depending on the meaning of thanpower, by Sept. 2024? In all liklihood Ukraine will be resolved by that time or the situation will have become so bad that gasoline prices will be the least of our worries.
If Canadian tar sands oil was (and for the parts already operational) for special refining in Houston and then for shipment to China and elsewhere, then there are no doubt contracts that would have to be met and agreements needing renegotiating. How long does that kind of thing take?
Germany has done a lot to develop green energy, but it still has more work in the pipeline, which was not planned for completion by winter 22-23. Delivery of LNG (gas) has been hampered by insufficient number of LNG pipelines. The link below discusses various German fuel plans, including new gas pipelines which, unfortunately, will not be ready before 2025. A week ago I heard Brent Crude was $104, not $140
