German Chancellor Olaf Scholz, and his colleagues from Denmark, Belgium and the Netherlands have signed a joint declaration to turn the North Sea into the ‘Green Power Plant of Europe’ in order to wean the continent off Russian energy supplies.

The declaration includes an agreement by the four countries to quadruple their combined current offshore wind capacity to at least 65GW by 2030, and to increase it tenfold to 150GW by 2050 - enough to power 230 million European homes.
