Energy is the material basis of social activities. In the 21st century, human society is facing a shortage of fossil fuels and the environment polluted situation, the era of cheap oil is over, and gradually change the energy consumption structure, vigorously develop renewable energy, take the road of sustainable development, new energy development and utilization of human consensus.
Solar energy is a clean, natural renewable energy, inexhaustible. Development and use of solar energy, both air pollution does not appear, it will not affect the ecological balance of nature, and as long as the sun reach the place, has solar energy can be utilized for its long-term nature of solar energy, renewable, non-polluting, etc. much people of all ages. At the same time, in today's world, conventional energy gradually reduced, while the world population growing year by year, the rapid development of science and technology in the near future, existing energy conversion systems will inevitably transform into a new source of energy. Energy is an important national economic development and people's living material basis necessary. In the past 200 years, based on coal, oil, natural gas and other fossil fuel-based energy system on a great impetus to the development of human society. But the human use of fossil fuels, but also poses a serious environmental pollution and ecosystem destruction. States have started according to national circumstances, governance and mitigation has been deteriorating environment and renewable, non-polluting development and utilization of new energy sources as an important part of sustainable development. Wind and solar power generation system is the use of wind and solar energy resources complementary, with the higher cost of a new energy system, with good prospects.
