    Vampire power is the energy drawn by electronics even when turned off. Annually this "wasted" power accounts for more than 100 billion kWh of U.S. electricity consumption and more than $10 billion. A surge protector can cut down on vampire power if turned off when electronics are not in use. Plus, they protect your electronics in case of a power surge or lightning storm!
