With the development of the economy and the progress of society, people put forward higher and higher requirements for energy, and the search for new energy has become an urgent task facing human beings. There are three main types of existing energy sources, namely thermal power, hydropower and nuclear power.

　　Hydropower will flood a large amount of land, which may cause damage to the ecological environment, and once a large reservoir collapses, the consequences will be unimaginable. In addition, a country's water resources are limited, but also affected by the season. Nuclear power is clean under normal circumstances, but in the event of a nuclear leak, the consequences are equally dire. The accident at the Chernobyl nuclear power plant in the former Soviet Union has damaged 9 million people to varying degrees, and the impact has not ended.

　　These all force people to look for new energy sources. New energy must meet two conditions at the same time: one is that it is rich and will not be exhausted; the other is that it is safe, clean, and will not threaten human beings and damage the environment. At present, there are two main types of new energy sources, one is solar energy and the other is fuel cells. In addition, wind power can also be regarded as an auxiliary new energy source. Among them, the most ideal new energy is solar energy.

　　Solar power is the most ideal new energy

　　The solar energy irradiating the earth is very huge. The solar energy irradiating the earth in about 40 minutes is enough for the energy consumption of human beings all over the world for a year. It can be said that solar energy is a truly inexhaustible energy source. And solar power generation is absolutely clean and does not cause pollution. Therefore, solar power is known as an ideal energy source.

　　Although power stations with solar pane generation is affected by day and night, rain and season, it can be carried out in a decentralized manner, so it is suitable for each household to generate electricity separately, and it must be connected to the power supply network, so that each household can sell it when the power is rich. Give it to the power company, and buy it from the power company when it's not enough. The technology to achieve this is not difficult to solve, the key is to have corresponding legal protection. At present, developed countries such as the United States and Japan have formulated corresponding laws to ensure the interests of households in solar power generation and encourage households to generate solar power.
