The UK chief of European energy giant Statkraft said Britain may need to call urgently on land-based renewables in the second half of the decade if its offshore wind sector fails in the “huge challenge” to quadruple installations by 2030.

David Flood said the UK government should put in place now the policy “levers and tools” for onshore turbines and solar to rapidly scale up deployments, including annual contract-for-difference (CfD) auctions – also a key demand in a new policy roadmap issued by the wind industry on Wednesday.
