UK’s ‘decisive shift’ on decarbonisation

Policies introduced in the UK in 2025 have represented a “decisive shift on the road to decarbonisation”, according to a new report.

GridBeyond’s latest Global Energy Trends report for the UK and Ireland said a focus on long-term planning, infrastructure investment, market reform, and industrial competitiveness have set the stage for a decade of unprecedented change.

“Both countries view clean energy not only as an environmental priority but as a cornerstone of economic resilience and national security,” it said.

In 2025, the report said the UK energy mix was already dominated by low carbon electricity, with renewables and nuclear together supplying around two-thirds of generation while gas have provided most of the remaining third and coal have effectively disappeared from the grid.

Over the rest of the decade, government and system operator plans point towards a much cleaner system by 2030, with clean sources expected to provide around 95% of electricity generation and gas playing only a residual and flexible role.
