According to reports from Energy Magazine, oil is expected to be developed within a few decades. In the end, nuclear power plants have the problem of nuclear waste disposal. It shows that the development of new generation energy is an urgent task. In the development of many renewable energy technologies, solar energy applications have received considerable attention from all walks of life, because it is the most reliable at present.
