THE MAIN ADVANTAGE OF SAVING ELECTRICITY IS TO SAVE MONEY
WHY SHOULD WE SAVE ELECTRICITY
The power company supplies electricity to our home for a fee.
The more we use that means the more we have to pay.
……Hence, we should use it wisely
HOW MUST DOES ELECTRICITY COST ?
Electricity is measured in units called Kilowatt Hours (KWH).
All Electricity used has to be paid for.
The hours of usage are tallied and charges are made according to the cost per kilowatt.
TECHNIQUES USED TO SAVE ELECTRICITY
There are several ways in which we can save electricity around our homes.
CAN YOU THINK OF ANY?
INCANDESCENT VS FLUORESCENT BULBS BULBS
FLUORESCENT BULBS
A Fluorescent bulb of 15 watts gives about the same light as a incandescent bulb of 60 watts.
INCANDESCENT BULBS
These light bulbs dissipate more heat than a fluorescent bulb and give less light.
SOLUTION
Where possible incandescent bulbs replaced with fluorescent tubes.
EFFICIENT ENERGY USAGE
It is good practice not to leave electric devices powered on after you have finished using them.
MACHINE DRYING OR SUN DRYINGTry to use your electric clothes
drier only at times when it is necessary. e.g, on a rainy day.
The electric drier uses electricity.
..…. It is therefore cheaper to sun dry your clothes where possible.
REFRIGERATOR MANAGEMENT
Don’t store hot foods in the refrigerator.
Don’t position the refrigerator next to any heating appliances e.g, stove.
Don’t position the refrigerator in the path of direct sunlight.
These situations make the refrigerator work harder than usual, therefore more electricity is used.
CONCLUSION
Saving electricity means saving money.
Electricity should be properly utilized within the household.
