The sun is the energy source for all things. Although we hate the strong ultraviolet rays in the hot summer, ultraviolet rays also have their advantages. Sterilization is an important point. Many bacteria in life can effectively kill the sun's rays. Photosynthesis can grow faster. The sun brings us more than just light, but also a steady stream of energy. Energy is very important to the earth now. The energy consumed by rapid human growth is huge, and some energy sources are non-renewable. Factors have led us to do everything we can to solve it, but it has always had little effect but has been damaged in other ways. Environmental pollution is one of the important points. A good environment is the primary condition for the survival of living things. We need new environmentally friendly and green energy sources to replace those that produce pollution, such as solar energy. Solar photovoltaic power generation is currently a widely used form. Wind power generation is also one of the sustainable energy sources, but it is slower than solar energy and has more restrictions. Most of the current outdoor lighting equipment in our cities uses solar photovoltaic power generation panels, which can meet the needs of lighting throughout the day.

China plans to achieve a comprehensive well-off society by 2020, and the level of the national economy has been greatly improved. Today's rural areas are also rapidly developing in the direction of cities. Especially in recent years, development has been placed in the central and western regions. The area is large and the population is sparse. To protect the environment and develop the local economy, the use of new energy is imperative.
