Most people use too much electricity and water at home. You can reduce the amount of energy by:
_ Using short shower heads or buy " low - low " showers
_ Turning off the lights and air conditioners before leaving home or whenever you aren't in your rooms
_ Keeping the refrigerator doors closed
_ Going to school by bike
If you take my advice, you won't have to pay so much for your bills, and you can save necessary energy.
