At present, the main electricity consumption in industry and people's life is to rely on coal, nuclear fuel and other resources to generate electricity, while coal, nuclear fuel and other energy sources are non-renewable energy sources. With the development of the global economy and the increase of population, the demand for electricity is increasing day by day, while the energy available for exploitation is decreasing, and the contradiction between the increase in demand for electricity and the shortage of power generation resources is becoming increasingly prominent. In the process of urbanization, people need more power to develop industries, decorate cities and realize household electrification, all of which form a continuous new demand for power. On the other hand, the process of using coal to generate electricity will release a large amount of carbon dioxide, which will have a direct impact on the atmospheric environment. Therefore, how to use natural energy, such as wind energy, solar energy, potential energy, etc. to generate electricity to alleviate electricity demand and protect the environment has become the focus of our attention.

At present, with the deterioration of the earth's atmospheric environment, natural disasters occur frequently, and the transition and improper use of electricity, gas, natural gas, etc. often lead to fires, and when fires occur, power supply is often interrupted. For this reason, emergency lights are all provided with exits and necessary positions in the current buildings, so that lighting is provided for people's escape when the power is cut off. However, the existing emergency lights all use coal electricity to charge batteries to store electric energy, which consumes valuable coal electricity resources, which is not conducive to environmental protection and energy saving and emission reduction.
