Wash fruit and vegetables, then use the water again.
热水 → 加热需要能源 → 用水少=用能少

We can use fans instead of air conditioners on cool days. We can open windows to let fresh air in. We can wear cool clothes like T-shirts and shorts in summer. Also, we can set the temperature to 26°C or higher and turn off the AC when we are not in the room.

Idea 3
Reduce（减量） : I can use a reusable water bottle instead of buying plastic bottles every day. I can also bring my own shopping bag to the supermarket.
Reuse（重复使用） : I can reuse old boxes to store toys or books. I can also reuse plastic bags as rubbish bags.
Recycle（回收利用） : I can sort the rubbish into different bins — paper, plastic, glass, and metal. Then the recyclable materials can be made into new things.
Think about what you do at home or at school every day — which of these can you do right now
