Solar power generation

Solar energy is the energy source from the earth's outer celestial body (mainly solar energy), which is the huge energy released by the fusion of hydrogen nuclei in the sun at the super high temperature. Most of the energy required by human beings comes from the sun directly or indirectly. The coal, oil, natural gas and other fossil fuels we need for life are all because various plants transform solar energy into chemical energy stored in plants through photosynthesis, and then form the plants and animals buried underground after a long geological time. In addition, water energy, wind energy, wave energy, ocean current energy and so on are also converted by solar energy.

With the development of economy and the progress of society, people put forward higher and higher requirements on energy, and the search for new energy has become an urgent task facing mankind. There are four main sources of existing power sources, namely, thermal power, hydropower, nuclear power and wind power.
Thermal power requires burning fossil fuels such as coal and oil. On the one hand, limited reserves of fossil fuels, burning less, are facing the risk of depletion; Burning, on the other hand, would release oxides of carbon dioxide and sulfur, thus causing greenhouse effects and acid rain, which would worsen the earth's environment.
Hydropower would flood vast amounts of land, potentially causing environmental damage, and large reservoirs could collapse with dire consequences. In addition, a country's water resources are limited and subject to the seasons.
Nuclear power is normally clean, but in the event of a nuclear leak, the consequences are equally dire. The chernobyl nuclear power plant accident in the former Soviet union has damaged 9 million people to varying degrees. At 1346 hours on March 11, 2011, a 9.0-magnitude earthquake struck fukushima, Japan, triggering an accident at the fukushima nuclear power plant that shocked the world. The ocean resources within a radius of 5 kilometers will be affected by different degrees or variations in Marine life.
As a clean and renewable energy, wind power has a broad prospect of development. The development of wind power is an effective way to solve China's energy shortage. Wind power is a clean energy application and an effective way to reduce greenhouse gas emissions.
