Wind energy will take a prominent place at this month's Glastonbury pop festival. A 150 kW wind turbine is to be sited next to the main stage to help power the event, expected to attract 150,000 people over three days of music and other performing arts. "We want to have a powerful visual presence of a wind turbine at the festival," says John Sauven from Greenpeace who is one of an army of volunteers who help the festival run smoothly. "It is more of a public relations exercise really. We want people to see wind turbines, get close to them, see they look aesthetically pleasing, and see this is an environmentally benign form of energy." He expects the Bonus machine from Denmark will be photographed, filmed, and become a talking point.
