In May, for the first time ever, solar produced more electricity than coal in the United Kingdom. During last month, coal generation fell to zero on several days — possibly the first time that has happened since the country introduced widespread electrification in the late 1800s, according to analysis from Carbon Brief, a U.K.-based energy tracker.
Solar panels generated 50% more electricity than the fossil fuel across the month, as days lengthened and coal use fell. Solar generated an estimated 1,336 gigawatt hours (GWh) of electricity in May, compared to 893GWh output from coal.
