Friday is set to be Britain’s first working day without coal power generation since the industrial revolution, according to the grid operator.

It follows coal-free periods in 2016 and reflects a rapid shift away from the polluting fuel.

A spokesperson for National Grid confirmed a tweet from the control room to that effect, adding that it was also expected to be the first 24-hour period without coal.

It looks likely that today will be the first ever working day in Britain without #coal since the industrial revolution!
