Energy Star savings for your home
The average home spends almost 20 percent of its utility bill on cooling. These cooling bills can be lowered by simply changing out incandescent light bulbs with EPA’s Energy Star qualified lighting, which use less energy and produce approximately 75 percent less heat. Raising your thermostat by only two degrees and using your ceiling fan can lower cooling costs by up to 14 percent too. http://www.energystar.gov/index.cfm?c=products.es_at_home
