Global offshore wind power capacity will explode in the coming decades as the energy transition supercharges build-out to reach as much as 1TW of plant by 2050, according to latest calculations by the International Renewable Energy Agency (Irena).

The agency, which last year estimated offshore wind of around half this volume would be installed by mid-century, has revised its forecast upward based on a foreseen mushrooming of an Asia Pacific market it predicts will grow from the current 5GW to 613GW as the region becomes home to over 60% of the sector’s total global capital spend.
