Once you have an appliance’s wattage rating, consult the table on the next page. It tells you how much electrical energy (measured in kilowatt-hours) the appliance consumes during
one hour of operation. And, the table tells you approximately
how much oil or coal was burned at your power station to
produce this amount of electrical energy.

Be sure you ask your mother for permission before you turn
over her kitchen appliances, and don’t try to move big
appliances without your dad’s help.
