Energy saving should be: (1) abandoned earth stoves and old coal stoves, gas stoves, induction cookers and microwave ovens with high efficiency; (2) use electrical appliances to stop people from walking; (3) Save every drop of water and pay attention to the reuse of water; (4) Technical transformation of power transmission and transformation equipment and electrical equipment to increase its scientific and technological content and improve energy utilization.

This topic is to understand the waste of a lot of energy, which is not only the destruction of the environment, but also the negative impact on human beings. Students should have awareness of energy conservation and environmental protection.
