This weekend, Britain showed that it’s possible in this day and age to live without coal —at least, when the conditions are right. For a stretch of time spanning more than 90 hours this Easter weekend, Britain generated no electricity at all from coal, marking the longest period since the industrial revolution. Thanks to sunny weather, the UK was able to generate a quarter of its energy from solar power while energy demand from consumers was low. Coal made up less than 10 percent of the country’s energy mix last year and will be less than that again in 2019. By 2025, Britain plans to phase out the last of its coal plants in order to reach its climate target.
