From the point of view of energy and sustainable development to promote the development and utilization of solar energy, the two main reasons, the urgent need to answer, please help the talented people, thank you.
In view of this, the human dream solar era has actually been in sight, including space to collect solar energy to transmit it to the earth, turning them into power, in order to solve the energy crisis facing humanity. With the progress of science and technology, this is not a dream. The world's first solar power station, built by NASA and the National Energy Agency, will soon be assembled in space and will soon start powering the ground.
Therefore, the power generation system is relatively simpler than the ground, and in the absence of weight, high vacuum environment, the strength of the device components are not too high. Moreover, solar energy and oil, coal and other fossil fuels, will not lead to "greenhouse effect" and global climate change, it will not cause environmental pollution. Because of this, the use of solar energy has been the focus of many countries, we are competing to develop a variety of new optoelectronic technology and optoelectronic materials, in order to expand the use of solar energy applications
For a long time, people have been trying to use solar energy. Our planet receives solar energy, only the total energy emitted from the surface of the sun is about 1/2000000000, the energy equivalent to 3-4 million times, the global total energy required is inexhaustible, inexhaustible. Secondly, there is no space between the day and night and four seasons, there is no dark clouds and shadows, radiation energy is very stable
