The invention of solar energy relives the tight supply of other natural resources. To use solar energy in order to replace other natural resources such as fossil fuel has following benefits. First, the sunshine is widespread and has no regional restrictions. You can get it anywhere if you want, whether land or sea, mountains or islands. It can be directly developed and utilized; also it does not need mining and transportation. Secondly, it can protect environment and using solar energy, it not only protect environment, but also will not pollute the environment. It is one of the cleanest energy and will not worsen pollution. Thirdly, the solar energy has huge capacity; the radiation of solar that can reach the surface of the earth each year is equivalent to 130 trillion tons of coal. Today, the total amount of solar energy is the world’s largest energy that can be developed. Finally, the persistence of the solar energy, according to the current production rate of nuclear that produced by sun, we can estimate the hydrogen capacity can be maintained ten billions of years. However, the life of the earth will be around billions of years, those data tell us that sun’s energy is inexhaustible.
Bottom Line: However, the use of solar energy is still in initial stage, mainly used as solar hot water system, solar greenhouse and solar power, we can apply solar energy to all aspects in near future.
