developed and used, easy to collect, and does not need to be mined and transported.
2) Harmless: The development and utilization of solar energy will not pollute the environment. It is one of the cleanest energy sources. This is extremely valuable in today's increasingly serious environmental pollution.
(3) Huge: The solar radiation energy that reaches the surface of the earth every year is equivalent to about 130 trillion tons of coal, and its total amount is the largest energy source that can be developed in the world today.
(4) Long-lasting: According to the estimation of the rate of nuclear energy produced by the sun, the storage of hydrogen is sufficient to maintain tens of billions of years, and the life of the earth is also about several billions of years. In this sense, it can be said that the energy of the sun is used for Inexhaustible.
