It's not just one thing, but the overall war on fossile fuels Old Joe has begun. When you take down the Keystone pipeline, eliminate oil leases, etc. your negatively reflecting the outlook for oil production. If oil production will be constrained in the future (plus an increase in current demand), prices start to go up.It can’t be that. Keystone XL was never even constructed, so it can not conceivably have any material effect on either oil supply or energy independence.
Also, can’t be Keystone I, II, or III, which have been operational since 2010, 2011, and 2016, respectively.
Like I said, I havent heard of any pipelines being shut down.
