A study for the Carbon Trust says that UK businesses will waste more than £500m worth of energy over the summer months. Businesses could cut their energy bills by as much as 15% if they were more careful about energy usage.
Last summer I was working in a hospital. It wasn’t the best office for natural light, but when there was no-one else there and the sun was good enough I’d turn off a bank of lights. Sooner or later one of the bosses, who worked in another office, would come along, turn the lights on again and tell me off for saving energy (okay, not for saving energy, in fact they never actually explained why it was so bad I was turning off lights that weren’t in use).
