(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.
