Talking about the advantages of solar energy compared with other energy sources.

(1) Universality: the sun shines all over the earth, and there is no geographical restriction, whether it is land or sea.

Whether it is a mountain or an island, it is everywhere, which can be directly developed and utilized, 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, and 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 about 65.438+0.3 trillion tons of coal, which is the largest energy that can be developed in the world today.

(4) Long-term: According to the rate at which the sun produces nuclear energy, the storage of hydrogen is enough to last for several billion years, and the life of the earth is about several billion years. In this sense, it can be said that the energy of the sun is inexhaustible.
