What are the advantages of solar energy
Energy (solar), refers to the sun's heat radiation energy, the main performance is often said that the sun's rays. In modern times it is generally used to generate electricity or to provide energy for water heaters. Since the birth of life on earth, mainly to the sun to provide heat radiation to survive, and since ancient times, people also know how to use the sun to dry objects, as well as the production of food, such as salt and salted fish, etc.. In the case of dwindling fossil fuels, solar energy has become an important part of human energy use, and has been developing. There are two ways to use solar energy, such as photothermal conversion and photoelectric conversion. The broad sense of solar energy also includes wind energy, chemical energy, water, etc..
(3) huge: the annual solar radiation reaching the earth's surface is about the equivalent of about 130 trillion tons of coal, which is the largest energy available in the world today.(4) for a long time: according to estimates produced by the sun energy rate, amount of hydrogen storage sufficient to maintain the billions of years, and the life of the earth is about billions of years, in this sense, we can say the sun's energy is inexhaustible.
Advantages of solar energy:(1) common: the sun shines on the earth, without geographical restrictions, whether on land or in the sea,Regardless of the mountains or islands, are everywhere, can be directly developed and utilized, easy to collect, and no mining and transport.(2) harmless: the development and utilization of solar energy will not pollute the environment, it is one of the most clean energy, environmental pollution is becoming more and more serious today, this is extremely valuable.
