1. Solar energy is harmless. The development and utilization of solar energy will not pollute the environment. It is one of the cleanest energy sources.
2. Solar energy is widely used in water heaters, street lighting and so on. This reduces the use of electricity by humans, and solar energy has no geographical restrictions, whether land or sea, mountains or islands, everywhere, can be directly developed and utilized, and does not need to be mined and transported.
3 The area illuminated by sunlight is scattered in most corners of the earth. The difference in incident angle is different, but it is at least not monopolized by a few countries or regions, resulting in a unnecessary energy crisis.
4. The sun’s energy is extremely large, and scientists have calculated a period of at least six million years. For humans, such time can be described as infinite.
