I've tried to say this before but UK should be exporting energy not importing it, we arent even trying to do that. Most recent measure I saw was to ban/close a welsh open pit coal mine and opt to import coal from kazackstan instead, a country that shoots its own people.
We have giant debt, we have to get that attitude its really a lapse in security to not be able to provide for yourself. We're seeing Russia bomb a country for being democratic and at the same time we pay them money to carry on that campaign because we are so desperate for oil and gas we pay Russia a billion every day (europe) thats a real screwup collectively by all those governments. Energy security was a known factor decades ago, discussing stocks doesnt matter really you are risking capital and you might lose it or not see it back for decades thats your look out but UK being able to balance its trade properly does count especially on this energy question. It would be quite similar considering a lot of middle eastern oil imports, they have diabolical treatment of people in many cases.
USA has enough natural gas to supply every energy need it has. Any oil they have could be exported, instead they use it all and I think import. They can supply europe though it requires compression, its harder to do. They also should do more to balance their trade, they arent concerned in the end it will lead to inflation and a lot of failure & weakness which promotes terrible regimes in contrast
