The best way for Britain to keep its energy prices low is to wean itself off expensive fossil fuels altogether and increase its supply of cheap, domestically produced renewable energy.
Of the 76 billion cubic metres of natural gas consumed in Britain in 2021/22, 29bcm came from domestic supplies, while 32bcm came from Norway. Much of the rest was imported from Qatar, a British ally, and Peru. Britain’s refineries mostly predate the discovery of North Sea oil and are instead designed to process Libyan oil, which is both much heavier and much lower in sulphur content.
