In the 1970s, rolling power cuts caused by coal strikes led to the three-day working week and the eventual collapse of government. Since then, keeping the lights on has been a priority. But it’s a task that’s getting ever harder, especially amid rising tensions between Europe and Russia, one of the continent’s main oil and gas suppliers.
