Benefits of solar energy
Solar energy has the advantages of universality, harmlessness, large reserves, and long-term use.
(1) Universal: The sun shines all over the earth, no geographical limitation, no matter whether it is land or sea.
No matter the mountains or islands, they are everywhere and can be directly developed and utilized, which is convenient for collection and does not require 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.
(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.
From the energy conservation and emission reduction targets of various countries and the United Nations' "Special Report on Renewable Energy", it can be seen that achieving a high proportion of renewable energy substitution by 2050 is a worldwide trend, which will promote the development of China's solar photovoltaic power generation industry.

By 2030, the entire energy demand will reach 5 billion tons of standard coal, and by 2050 it will reach 5.2 billion tons. Renewable energy will account for 40% of the total energy demand in 2050, and renewable energy will account for 60% of the electricity demand. Photovoltaic The installed capacity of power generation may reach 1 billion KW. The strong support of national policies will promote the rapid and healthy development of China's solar photovoltaic power generation industry.
