答案
Hello, everyone. Do you know where energy comes from?
My favourite green energy is solar power. Solar power comes from the warm sunlight. It is very clean, and it will not produce dirty pollution to hurt our Earth. We use it to heat cold water, and we also use it to get electricity for our lights and TVs at home.
To save energy and protect our lovely home, we can do lots of easy things in daily life. We should turn off the lights in time when we leave a room. We can go to school on foot or by bike, not by car. We can reuse the clean water after washing vegetables to water our flowers. We can also recycle paper and plastic bottles to save more resources.
Our Earth is the only home we have. Small changes can make a big difference.
