Plans would only supply Britain with fossil fuels for an additional three weeks a year, analysis finds

New oil and gas fields in the North Sea would produce only enough gas to satisfy the UK’s needs for a few weeks a year, with a minimal impact on energy security, analysis has found.

Fields now under consideration would supply at most an additional three weeks of gas a year to the UK, from 2024 to 2050, even if none of the gas was exported.
