Re: Not just tech
Oil is a global market because it is easy (relatively speaking) to move around on tankers. The WTI price in the US is lower than the Brent price in the EU by a few dollars/pounds/euros because the US produces all the oil it needs and there is less shipping involved. But the price can't diverge too much because it only costs a few dollars per barrel to ship it halfway around the world and there are plenty of tankers to carry it.
Gas is different because while it is possible to move around on tankers there is much less infrastructure (both facilities to deal with it, and tankers able to carry it) to do so, so mainly it is only available where pipelines go. Gas is FAR cheaper in the US than in Europe (even before Putin's lost cause) and has been for years because the US produces more than it needs, which is why the industry has been building infrastructure for CNG tankers. Europe wasn't looked at as being a major market for those tankers at the time, of course.
