On the one hand, the new energy is not distributed in a centralized way, such as the centralized distribution area of wind energy, ocean energy and geothermal energy is not suitable for human residence; on the other hand, the new energy is not fully and reasonably utilized, for example, the solar energy is widely distributed, and a large amount of available solar energy is available in cities with large population density. Solar energy is the most extensive, universal and distributive clean energy technology in the current renewable energy technology.
