Your LNG price chart is dated. It is from May 2022. LNG and natural gas prices are way down since then, in the US and Europe.
Russian pipeline gas was coming into Germany at the price equivalent of $25 barrel of oil. But how could Germany/Europe keep buying cheap Russian gas, after Russia invades a European nation called Ukraine? This would be crazy. Ukraine is European and wants to align even more European. Same as Poland does. Align in trade and politically. This is what rat face Vlad could not handle
The graph is a COMPARATIVE of pipeline nat gas costs vs LNG shipped in a tanker, based on the distances of the shipping and the lengths of the pipelines.
You get that, right?
The RATIO stays the same even as global prices fluctuate.
