That's the Keystone Pipeline which was a Candian pipeline that wasn't in operation as only 8 or 9 percent of it was completed. It wasn't actually adding oil to the world as it wasn't completed. So, that had no actually bearing on oil prices.
Oil prices have gone up because the world is getting back to opening and people were going back to work and traveling. Supply and demand, OEPC, analysts, weather conditions, and natural disasters control the price of oil, not presidents.
That means that with more electric vehicles on the road, the demand for oil will be less, meaning there should be more of it, which in turn means that the price should overall come down.
I'm going to have to disagree with you on that one. I know how businesses work. If they will be out of business soon, then they might price gouge to make as much money as possible before their company is gone.
