Few consumers understand that many of today’s electronics consume power while not in use. These energy vampires can account for $100 of a home’s yearly power cost, wasting up to $10 billion annually in the US. WattBlocks act as a way to block power to appliances when they aren’t in use. Users plug vampire appliances into the WattBlock power strip. A separate master step switch is plugged into an outlet near the front door. When homeowners leave they simply step on the switch and it sends a signal through the home’s power lines, telling all WattBlocks to block power to the vampires. Users can save up to 20,000 Watt-hours every month.
