Great British Energy Act receives Royal Assent and creates a public clean-energy investment framework

The Great British Energy Act received Royal Assent on 15 May 2025. It established the statutory framework for Great British Energy, defined clean-energy production and related objects, authorized financial assistance and required strategic priorities. In the causal graph this event sets in motion Renewable capacity buildout, a driver that strengthens Renewable share of global electricity generation — an improving welfare path.
