"Look For The ENERGY STAR Label If a product has the ENERGY STAR seal, it meets certain energy efficiency standards. Home appliances, electronics, windows, and roofing are just a few of the products that can qualify, so check a product’s box or manual, or speak to a salesperson to see if it is ENERGY STAR compliant. In 2006, ENERGY STAR products helped US consumers save an estimated $14 billion on their utility bills. In addition to energy savings, there are rebates and federal tax credits available for some ENERGY STAR products. Visit ENERGYSTAR.gov or our energy section for more information.
