You're feeling inspired yet practical today. Now's a great time to look beneath the surface for efficient solutions. Unearth the energy zappers in your home with a wattage meter. It's an inexpensive device that monitors the energy consumption in your home. Just plug an appliance into the unit: it'll tell you everything you want to know about usage and ultimately cost. This is a great idea, especially if you're thinking about purchasing an energy-efficient appliance and want to create a cost-benefit analysis.
