Write a paragraph about 50 - 60 words on the topic: How to save energy at your school.

There are some ways for students to save energy at school. Firstly, students should turn on electric devices if necessary and turn off all of them when they are not in classrooms. Secondly, students can plant trees at school when school launches the planting tree movements. Lastly, classifying litter into recycle one and non-recycle one is another great measure for students to save energy at school.
