2. What is NAECA III ? The National Appliance Energy Conservation Act of 1987 is a United States Act of Congress that regulates energy consumption of household appliances. These laws and regulations have to do with creating mandatory standards that deal with the energy efficiency. These standards were put in place to ensure that manufacturers were building products that are at the maximum energy efficiency. Since these standards have gone into effect they have positively affected both the American economy and the environment. Americans who have purchased these appliances have been saving money on their electricity bills every year. It is estimated that these savings have been greater than $300 billion. WHAT IS NAECA III
