Advantages of solar energy

Release Time:


(1) Universal: The sun shines all over the earth, without any regional restrictions. It can be developed and used directly on land or in the sea, in mountains or islands, and it is easy to collect without mining and transportation. (2) Harmless: The development and utilization of solar energy will not pollute the environment. It is one of the cleanest energy sources, which is extremely valuable in today's increasingly serious environmental pollution. (3) Huge: The solar radiation energy reaching the earth's surface every year is equivalent to 130 trillion tons of coal, which is the largest energy that can be developed in the world today. (4) Long term: According to the estimation of the rate of nuclear energy generated by the sun, the hydrogen storage is enough to last for tens of billions of years, while the life of the earth is also about billions of years. In this sense, it can be said that the sun's energy is inexhaustible.
