Ben Green doesn’t have to worry that Vladimir Putin might cut off Europe’s gas this winter, fret about a seasonal revival of Covid-19, or panic about a looming global food crisis.
Green weaned himself off gas when he purchased the five-hectare (12-acre) grounds of a derelict East German army barracks three years ago: the previous owner, who used it as an outdoor museum for vintage tanks, had gutted the building of water and gas pipes. Green patched up the roof of the refectory and insulated the windows so that temperatures inside don’t drop below 5C at night. He bathes by pouring a bucket of cold water over his head and cooks on a wood-burning stove.
