Home Energy Audit Lab Assignment Everyday our for every activity we perform, energy must be utilized. There are many energy such as nuclear, chemical, and electrical. In our home we appliances that do a variety oftasks for us. Appliances such as air conditioning, heaters, lights, washing machines, toasters, and microwave all make our lives easier. fuel bod eat chemical energy, but these appliances require an input of electrical energy that has been created by a fuel source. we The amount of electricity that each appliance uses is measured in Watts (rate that the appliance uses energ). Our electric bills reflect the amount of energy in our homes as kilowatt hours It is important that we evaluate how much electrical energy we are using (and possibly wasting to determine if we can reduce our electrical energy usage, which, in turn, will reduce the amount of fuel needed to generate electricity. Reducing the electrical energy you use daily can effect your electrical bill, but can also reduce negative impacts associated with fuels used to create electrical energy. Your lab will be attached data table. You will be evaluating the electrical power usage of four completed on the done for you (please how to different appliances. Two appliances have been understand appliances to audit). Closely examine these examples to be sure that you do the calculations involved in the audit. 1. Choose four appliances you wish to evaluate in your household and fill in their names along the top row of the "Appliance Survey. Determine how many Watts an appliance uses when on by using either the label on the ppliance or the Wattage tables attached. Fill in the appropriate boxes. 3. Approximate how many hours per day an appliance is used. Fill in the appropriate boxes. Approximate how many hours a day if an appliance is left on when nobody is using it. Fill in the appropriate boxes. 5. Determine ifyour appliance leaks energy (check out the attached charts). If it does, determine the approximately amount ofwattage that is leaked and fill in the appropriate boxes. 6. Calculate the total time an appliance is on and off in one month and fill in the appropriate boxes. 8. Calculate the Watt-hours an appliance used when on and fill in the appropriate boxes. Calculate the total rs by appliance in one month and fill in the appropriate boxes. 9. Convert the total Watt-hours to kilowatt-hours (kWh) and fill in the appropriate boxes. 10. Calculate the energy cost for this appliance per month assuming the electricity cost$0.10 per kWh and fill in the appropriate boxes.

Explanation / Answer

Answer: I am lisiting five appliances, however you can use any four as per your convinience.

Three things that we can do in our home to reduce the amount of electrical energy used:

Replacing work of three appliances if you did not have electricity:

To reduce the amount of leaking electrical energy we should not keep the instruments on stand-by mode and switch them off when not in use.
