1. Reduce the proportion of traditional fossil energy such as coal and oil in the energy structure, and reduce the emission of carbon dioxide and pollutants, resulting in environmental pollution;

2. In dealing with the energy problem after the depletion of traditional fossil energy, compared with traditional fossil energy, clean new energy such as solar energy and wind energy are inexhaustible;
3. The development of new energy can effectively slow down the over exploitation of traditional resources, provide a buffer period for the deteriorating environment and curb the further deterioration of the environment;
4. Reduce human health problems such as loss and disease caused by environmental degradation
