My name is Nam. Today I'm going to tell you how to save home energy.

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-flow' showers;

-turning off the lights and air conditioners before leaving home or whenever you are not 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.

Thanks for listening.
