Plenty, but these days mostly if you either (a) want a simple implementation or (b) don't have to worry much about cache locality. The problem is that (b) doesn't really exist outside of retrocomputing and embedded systems these days. It's still one of my favourite data structures, just because it's a clever way to get most of the benefits of more complicated datastructures on small systems with minimal code.
Occasionally in pure python "asymptotically reasonable, simple implementation, terrible memory locality" is the right pick for a data structure. You want to avoid an extra linear term, you don't care too much about the constant factor, and the cache doesn't really matter because the language is so slow that it's not really noticeable.
It's a tool with a long vintage, and it wouldn't make sense to port it to a different language just to take advantage of the likes of bubbletea or textual.
The US is not in a position to process much of the sweet crude it has. Instead, imports sour crude, which is what much of the US's refineries are actually built to handle. This is why Venezuela was such a thorn in the side of the US, as they were one of the major producers and also largely produced sour crude.
As adwn says, it's a globally priced commodity, and the US is not in a position to disentangle itself from that market because in spite of being one of the world's largest producers, US refineries are not in a position to process that product, so it needs to go abroad. The US needs to import significant amounts of sour crude to be refined for their own use.
The US is just as screwed as the rest of us.
Also, the primary worry for Europe isn't oil, it's natural gas.
The 'sell electricity to Ireland' bit here is doing an awful lot of work. It's more complicated than that.
For those who don't know, Ireland operates an all-island grid, and EirGrid (the grid operator for the Republic) owns SONI (the grid operator for Northern Ireland). That means that 'UK' and 'Ireland' in this has a large Northern Ireland shaped lump of ambiguity that statement.
It shouldn't be that complicated. The UK sells electricity to Ireland (and vice-versa?) in the same way that Belgium, France, the Netherlands, Denmark and Norway sell electricity to the UK, and vice-versa.
Don't tell me EirGrid's EWIC that comes onshore at Dublin and Greenlink at County Wexford are an "NI-shaped lump". They are sources of electricity for the whole island, when it's needed, just like the UK's interconnects with the continent.
