We all know the Sun is important. But how does the Sun do that? It's the Sun's energy that makes life live on our planet. Energy from the Sun is called solar energy.People started to use solar energy many years ago. They build houses with windows so that the sunlight can get inside and make them warm.
It has something to do with solar panels(太阳能电池板). Solar panels collect energy from sunlight to make electricity(电).
But what happens when it is cloudy or rainy? Solar panels cannot collect energy from sunlight on cloudy and rainy days. We needn't worry about it because solar panels have batteries (电池) in them to keep electricity.
The Sun makes more energy than people use now. At the same time, solar energy is good for the environment(环境).And we can't use it up. So we should try our best to find more good ways to use it in our life.
A. We can also turn the Sun's light into electricity
B. It will not pollute the air and water.
C. It gives sunshine to plants, animals and people on the Earth
D. Solar energy makes us feel warm when we sit in the sunlight
E．People can't live without sunlight.
F. We can use the kept electricity at night or on cloudy and rainy days.
