Its simple supply and demand. The supply doesn't match the demand, so prices rise.
Supply can't be provided because the pipeline doesn't exist. You can rabbit all the propaganda you want, but anyone with half a brain can see that western governments have pursued some pretty dumb policies when it comes to energy supply and they are now paying the price.
Whether that is the US trying to pretend that it won't use oil, to Europe thinking wind and solar will replace nuclear, it's all made us more dependent on the Saudis and Russia, a devastatingly dumb and short-sighted plan driven by faulty science and propaganda.
Ironically, some of it Russian propaganda that the left normally sees everywhere.
