Insights director at global energy think tank Ember Dave Jones said: “The renewables revolution is gathering pace around the world, and renewables will soon overtake coal as the single biggest source of global electricity. Once, coal power was a byword for industrial growth, now clean energy is driving economies.”

In the absence of new infrastructure and technology, the shift to more intermittent sources of power could leave the national grid more vulnerable to power cuts than it has been for decades… The health of the country’s economy — and the willingness of other countries to follow — may very well ride on the experiment’s success.

Armstrong understood that renewables would be cheaper energy sources in the long run compared to burning dirty coal, but his was essentially a lone voice. The presumed abundance of coal led to the commissioning of the world’s first coal power plant in 1882. The U.K.’s coal plants have since burned through 4.6 billion tonnes of coal, emitting 10.4Gt of CO2, stresses Dr Sim Evans, deputy editor of Carbon Brief.

Firstly, if the rest of the world is going to be inspired by the decommissioning of Britain’s coal-fired plants there is little sign of it yet… Britain may have managed to displace coal with a combination of gas and wind power, with a small contribution from solar (4.9 per cent last year), but it is not a practical course for many countries which do not have easy access to gas supplies, and who would have no other practical means of coping with the intermittency of wind and solar. The advantage of coal is that it is very easy to transport, store and stockpile.

“The Hinkley Point project, which is already under construction, will supply electricity that is far more expensive than green energy. If it is done well, the German model combining the phasing out of nuclear energy and coal could be more favourable. But the top priority is that the newly industrialising and developing countries also switch to phasing out coal as quickly as possible. First and foremost China, which is still building new power plants. If they don’t change course, the joy over the end of the coal era in the UK will be of little use.”
