The Darkness

For most of the 20th century, coal was Britain. It powered the factories that rebuilt the nation after two world wars, heated homes through harsh winters, and employed over a million men at its peak. In 1990, coal still generated about 80% of the country’s electricity . But coal was also the engine of a deep and painful social contract. When Prime Minister Margaret Thatcher’s government moved to close more than 20 coal pits in 1984, tens of thousands of miners walked out. The strike lasted a year, divided families and communities, and ended in a bitter defeat that broke the power of Britain’s trade unions and accelerated the collapse of mining towns across Wales, Scotland, and the North of England .

The human cost of that transition is still felt today. Communities that were built around a single industry were left with unemployment, addiction, and a sense of abandonment that would later fuel political resentment for decades. The closure of the last deep coal mine in 2015 was, for many, not a cause for celebration but a painful reminder of what had been lost.

The Breakthrough

And yet, something else is also true.

Between the end of the miners’ strike and the final closure of the Ratcliffe-on-Soar power station in September 2024, the United Kingdom did something no other G7 nation has yet achieved: it systematically removed coal from its electricity system . The government introduced a carbon price floor in 2013, made coal uneconomical compared to gas, and then watched as renewables began their extraordinary rise.

By 2025, the transformation was complete. The National Grid’s live data shows that coal now contributes exactly 0.0% to the electricity mix [source: https://grid.iamkate.com]. Wind alone supplied 30% of all electricity in 2025, up from just 7% in 2010. In February 2026, zero-carbon sources—wind, solar, nuclear, and hydro—delivered 63% of Britain’s electricity, the highest February share in six years . Carbon intensity fell to 136g per kilowatt-hour, a fraction of what it was two decades ago. The country’s last coal plant, Ratcliffe-on-Soar, is now scheduled for demolition, its site designated for a new zero‑carbon manufacturing and technology hub within the East Midlands Freeport .

This is an AMAZING moment because it proves that a major industrial economy can decarbonise its power sector while keeping the lights on. The UK’s experience provides a real-world blueprint for the rest of the world. Between 5:30pm and 6:00pm on 5th December 2025, British wind farms averaged a record 23.94GW of generation—enough to power nearly all of the country’s homes [source: https://grid.iamkate.com].

The Honest Complexity

I want to be honest with you. The end of coal did not mean the end of fossil fuels. Gas still supplied 28% of UK electricity in 2025, and nuclear output has fallen to its lowest level in 50 years . The government has yet to produce a credible plan for phasing out gas, and some experts warn that unproven technologies like carbon capture and hydrogen are being used to delay real progress . Electricity imports from France, Belgium, and Norway now make up around 15% of the mix, raising new questions about energy security . The transition also did not automatically create good jobs for the workers left behind. Unlike the coordinated support some European countries provided, Britain’s coal phase-out left many former mining communities without a clear economic future.

What We Do Not Need to Repeat

We do not need to repeat the tragedy to keep the lesson. The lesson is that governments can act, that carbon pricing and clean energy investment work, and that the end of a polluting industry can be the beginning of something better if we manage it with care. The lesson is also that we must do better this time. As the UK now turns to phasing out gas, the question is whether it will learn from the mistakes of the coal era—whether it will provide retraining, investment, and a genuine plan for the communities that will be affected .

Closing

The most durable societies in history were not the ones that clung to the past. They were the ones that managed change with honesty and with care for the people who carried the cost. In 2026, Britain is no longer a coal-burning nation. What it becomes next is still being written. That is not a guarantee. It is a choice.
