With energy costs across the country climbing, consumers must become more aware of how their everyday activities use e lectricity, and the cost associated with those activities. This exploration of household energy consumption will help you gain an appreciation of how much energy your family uses on a daily basis, and how much money that energy consumption costs. To do this, you will: 1. Monitor and record your family’s use of a specific household appliance over a 24 hour period, noting the time of each use, and the length of time the appliance is used. 2. Research your chosen appliance (using resources such as the owner’s manual, and the internet) to obtain the following information/specifications: i. Year, Make (Panasonic, LG, Black & Decker, etc), Model ii. Power Source, Power Consumption iii. (Optional) Energy Star Rating, Consumer Ratings, etc 3. Describe what happens with the appliance when it is not being actively  used. Is it left on and/or plugged in? If so, is it consuming energy during this time? How much energy (Calculate)? 4. Calculate how much energy was consumed during the 24 hour period, when the appliance was actively  in use. 5. Calculate the Average use time of the appliance. Hint:    () ()    () ( )  6. Calculate the average  energy consumption per use of the a ppliance. Hint:    ( ) () ()  7. Consulting appropriate resources (recent Power Bills, Nova Scotia Power http://www.nspo wer.ca/en/home/residential/billing/po werrates/default.aspx ) calculate the cost  of the energy consumption of the appliance during: i. Entire 24 hour monitoring period ii. One Average use of the appliance iii. All time when the appliance was not actively  in use iv. All time when appliance was actively  being used 8. Analyze the various cost calculations, and explain whether y our family’s use of your chosen appliance is efficient  and cost effective , and justify your responses.
