The King of Wales wants to use the proceeds of a new multi-million pound wind farm deal with the Crown Estate for the "wider public good", Buckingham Palace said. Profits from the Crown Estate finance the British Crown, and profits from it finance the maintenance of the Crown. Crown Estate has secured agreements for six offshore wind projects worth around £1bn. Six projects could start generating green electricity by the end of the decade, potentially powering seven million homes. The Sovereign Appropriation is 25% of the Crown Estate's annual profits and is used to cover the expenses of the Crown.
