Britain has gone without coal-generated power for an entire week for the first time since the Industrial Revolution.
The last coal generator came off the system on Wednesday, May 1 at 1.24 pm GMT, the National Grid Electricity System Operator tweeted.
On Tuesday, 56.9 per cent of Britain's electricity was produced by natural gas.
Nuclear energy was the next largest sector at 20 per cent, according to figures provided by the National Grid Electricity System Operator Control Room, the MailOnline reports.
Prime Minister Theresa May marked the occasion with a tweet on Wednesday, attributing the milestone to the Government's investment in renewable energy.
"I am proud that Britain has gone a record week without using coal to generate power," she said.
"Our investment in greener forms of energy is reducing emissions and ensuring we leave our planet in a better state for the next generation," Mrs May tweeted.
Fintan Slye, director of National Grid Electricity System Operator, said Wednesday that coal-free power would become the 'new normal' as Britain generates more power from wind, solar and other renewable sources.
A spokesman for the National Grid added: 'As more and more renewables come onto our energy system weekends like this are going to increasingly seem like the 'new normal'. We believe that by 2025 we will be able to fully operate Great Britain's electricity system with zero carbon.
'The transformation of how we get the energy to heat our homes and power our work is a massive change, but the advantages it brings in terms of green energy far outweigh any challenges.'
The Government plans to phase out Britain's last coal-fired power plants by 2025 in a bid to cut carbon emissions.
Coal currently accounts for under 10 per cent of the country's power output.
Of the 31.45 gigawatts (GW) powering the UK on Sunday, none was accounted for by the use of coal-fired power stations.
A GW of power will provide enough energy for about 700,000 homes.
