In Guyang-ri, a farming village of 70 households about 90 minutes south-east of Seoul, people gather for communal free lunches six days a week. The meals are funded by the village’s one-megawatt solar installation, which generates roughly 10m won ($6,800) in net profit each month.

“Residents eat lunch together every day, so we see each other’s faces, talk together,” says Jeon Joo-young, the village chief. “Bonds and solidarity between residents become much stronger. Life becomes more enjoyable.”
