Most energy conservation programs are sponsored by state or local governments OR by public utilities. These programs encourage homeowners or other end-users to purchase high energy efficient products by offering cash rebates or tax credits. By far the biggest eligibility criteria for these programs is ENERGY STAR® Program qualification.
