Much can be done to reduce the environmental impact of new buildings, of course. One obvious starting point is sourcing low-carbon energy to power them, such as by building solar projects nearby. "Your energy consumption should all come from renewable energy," says Dale Vince, owner of Forest Green Rovers football club in the UK and founder of Ecotricity, a renewable electricity company. "But at the same time, you should be super-efficient with that, using low consumption devices like LEDs for floodlights, for example, and energy efficient appliances."
