To conserve energy in our daily life. (Yui.S)

 There are several ways to conserve energy. First, when I go shopping to the supermarket, I always bring my own bag and refuse plastic bags. That is how I don't waste the petroleum. Second, after I take a bath, I often use  the water left the bathtub to do the laundry. By using that water, we can save a large amount of water. Third, not to use too much light, I never foget to turn off the TV after watching. In conclusion, there are many more things that we can do in daily life.
