Lighting is one of the least energy-efficient practices in the home, with a mere 10 percent of energy used providing actual light, the remainder providing unwanted, unnecessary heat. One of the three main greenhouse gases, carbon dioxide (CO2) is emitted whenever a light is turned on. And given that lighting generally accounts for about a 10th of a homeowner’s energy bill, lighting is one of the least environmentally sound aspects of modern living.
