The North Sea's long decline
From 4.4 million barrels a day to roughly a million
A basin past its peak:
Commercial North Sea production began in 1975, after 1960s exploration, and peaked around 2000 at roughly 4.4 million barrels of oil equivalent per day. Reservoir depletion has driven output down steadily since — to approximately 1 million boed by 2024, with regulator projections pointing to around 660,000 boed by 2029. The UK now imports more than half its gas needs, a sharp reversal from its decades as a net exporter. Around 30,000 people still work directly offshore, supporting production hubs that will progressively close as fields deplete.

Tax, decline, and a contested transition:
Facing falling output and a need to fund renewable investment, the UK government raised its windfall tax (the Energy Profits Levy) on North Sea producers to 38% in October 2024, taking the sector's headline tax rate to 78% — among the highest in the world — and extended it to March 2030. Industry groups argue this accelerates investment flight from a basin that could still add billions to the economy; the government and climate campaigners counter that continued extraction is incompatible with UK climate targets and that capital is better redirected to renewables, which grew three times faster than the overall economy in 2024. Both sides agree the basin's oil-and-gas era is winding down — the disagreement is over how fast, and what replaces the jobs and tax revenue it has provided for half a century.

Drax — the UK's largest renewable generator, and its most contested
Coal-to-biomass conversion, carbon capture ambitions, and ongoing scrutiny
The transformation:
Drax Power Station in North Yorkshire converted from coal to biomass (wood pellets), becoming the UK's single largest renewable electricity generator and, by generation volume, the largest decarbonisation project in Europe. The company is pursuing Bioenergy with Carbon Capture and Storage (BECCS), aiming to permanently capture and remove up to 8 million tonnes of CO2 a year and become carbon-negative by 2030, alongside pumped-storage and hydro assets in Scotland including Cruachan Power Station, built inside a hollowed-out mountain.

The scrutiny:
Drax's classification as "renewable" is genuinely contested. Critics, including environmental groups and investigative journalists, have raised concerns about whether its wood-pellet sourcing is as sustainable as claimed and whether burning imported biomass delivers the carbon savings the subsidy regime assumes; Drax has denied allegations of deliberate wrongdoing, calling some claims "false, inaccurate, and misleading." The UK government has responded by tightening sustainability sourcing rules and restructuring Drax's subsidy contract: from 2027, its annual output will roughly halve, from around 15 TWh to around 6 TWh, alongside the stricter rules — a sign regulators are recalibrating rather than abandoning biomass, but a real scaling-back of its role in the UK's power mix.

Questions
Questions about UK energy
Is burning wood pellets for electricity actually "renewable," and why is Drax controversial?
It depends on which part of the claim you're evaluating, and reasonable people disagree. The renewable argument: trees can be regrown, so — over a long enough timeframe, and if pellets come from sustainably managed working forests rather than old-growth or newly cleared land — the carbon released in burning is eventually reabsorbed by new growth, unlike coal or gas, which release carbon that took millions of years to form and will never be reabsorbed on any human timescale. That's the basis for classifying biomass as renewable under most current accounting frameworks, including the UK's. The critique: "eventually reabsorbed" can mean decades, which matters a great deal if the climate problem is urgent now; and critics have questioned whether all of the wood Drax burns actually comes from the sustainably managed sources it claims, versus material from more ecologically valuable forests. Drax disputes the more serious version of these allegations. What's not really in dispute is that biomass carbon accounting is more complicated than solar or wind, where there's no combustion or forestry supply chain to evaluate — which is exactly why UK regulators have both continued to support Drax's carbon-capture ambitions and simultaneously tightened the sustainability rules governing what counts as eligible biomass, while roughly halving its subsidized output from 2027.
