Abstract

Energy efficiency "is using less energy to provide the same level of energy service". This experiment was designed to determined if my house or my grandparents house had more efficient appliances. The outcome might help find out what kinds of appliances use less energy and if so what brand they are.

A Watt meter was used to measure the amount of energy used in various appliances in two different households. The same type of appliances were used in each household although they varied in brands and size:TV, Dehumidifier,Clock/Radio, and a Computer. The Watt meter was hooked up for an hour and then the amount of energy used was collected from the Watt meter.

The amount of energy usage was very easily found that my family's appliances use much less energy than my Grandparents. My family uses 29.5 cents less per hour if all the five appliances were on, then my Grandparents spend. My five appliances wattage use per hour was about 60% less than my Grandparent's house. From this I concluded that new appliances use less energy than older less efficient appliances.
