UK energy secretary Kwasi Kwarteng is said to back plans for a massive expansion of onshore wind and solar capacity by 2030 and an increase to offshore targets, amid reports of rifts in the British government over upcoming plans to bolster energy security.

Kwarteng favours new targets to double onshore wind capacity from 14GW now to 30GW by the end of the decade, with offshore wind hitting 50GW from 10.4GW
