The UK has now gone a week without coal being a part of its energy mix.

The UK has gone one week without coal being used to generate electricity for the first time since 1882, according to the National Grid Electricity System Operator. The milestone was marked at 1.24pm on Wednesday 8 May, the time the last coal generator went offline a week previously.

Coal-fired power stations are still a part of the UK’s energy generation mix as a back-up during periods of high demand. The UK first went a day without using coal in power generation in April 2017.
