Due Wed, Feb 27
Estimate the Cost of Your Electricity Bill
1. Get a recent copy (within the past six months if possible) of your household's electricity bill and bring it to class. Alternatively, you may print off Pepco's cost per kWh from their website.
2. Make a list of all electrical appliances in your home and their power consumption (wattage). This list might include light fixtures (make sure to count the number of bulbs), refrigerators, dishwashers, electric ranges and ovens, microwaves, washing machines, clothes dryers, flat/curling irons, blow dryers, electric space heaters, televisions, DVD players, stereo equipment, cell phones (estimate charge time), and clothes irons. This list is not exhaustive, so be sure to include anything that draws a current (uses electricity) in your home.
Don't forget air conditioners (window units and central A/C), electric furnaces, and outdoor lights (porch lights or other lights outside). Make sure to count both computers and monitors. In short, if there is a cord leading from the device that is plugged into an outlet, you should include it in your list.
The power ratings are normally found on the power supply, somewhere near the cord that is plugged into the outlet. For larger appliances like refrigerators and microwaves, the power ratings are often on a sticker that is placed on the door or the door frame of the appliance. If you can't find the appliances wattage, write down the model number and we can look up the wattage online.
