There's energy conservation, and then there's energy efficiency. Both noble goals, of course, but there is a difference. If you want to conserve energy, so the thinking goes, turn down your thermostat and put on a sweater. Becoming more energy-efficient means using technology to help you consume less energy. So, how much do you know about making your home more energy efficient?
