I remember all the protests against the building of the terminal in Pembroke and the gas pipeline running across Wales.It is due to our domestic gas being sold on futures markets, current gas prices are low as we have a lot of LNG terminals, Mainland Europe doesn't however we have a few pipelines to the continent so we use our LNG terminals to import gas then sell it through the pipelines to Europe but they are at total flow capacity so there is more gas than the UK can consume or sell and the wholesale prices go down.
But our gas bill is based on future markets where it is assumed this will have balanced out and the UK will be back to paying non artificially decreased prices.
Some proof , I learnt that from a video but here's a short article https://www.thisismoney.co.uk/money...ing-gas-price-surplus-lower-energy-bills.html
No protests against wind turbines ruining our landscape though. The pipeline is of course totally invisible now.
