Student Worksheet

Tune In: How much electricity did you use today?

Instructions: In this activity you will be working out how much energy you use on average over one day. Follow the instructions to fill in Table 1.

Step 1:

Write down the name of the appliance in column A. Write down the watts used for that appliance in column B. You also have a general guide to the wattage of many appliances. Only use the wattage printed on the appliance if you can easily see it without poking around.

Estimate how many hours you used the appliance for and write that figure down in column C.

Step 2:

In column D work out the units of electricity used. To do this:

Multiply the watts by hours used (column B x column C)
Divide by 1000
Write the answer into column E

Step 3:

In column F, write the cost by multiplying the units used by the price per unit.

You can find the unit price on the electricity bill. It is usually represented as rate c/kWh (cents per kilowatts). If you prefer, do your calculations on a spreadsheet application.
