1. Universality. The sun shines on the earth, regardless of the land or sea, whether it is a mountain or an island, it can be developed and utilized directly, and it does not need to be mined and transported. On the earth, wherever there is solar energy, it can be developed and utilized on the spot. There is no transportation problem, especially for rural areas, islands and remote areas where transportation is underdeveloped.
2. Harmless. The development and utilization of solar energy does not pollute the environment. It is one of the cleanest energy sources. This is extremely valuable today when environmental pollution is getting worse. Solar energy and wind energy are a clean energy source. When developing and utilizing, there will be no waste residue, waste water, waste gas, no noise, and no impact on the ecological balance. There is absolutely no pollution or pollution.
3. The amount is huge. The annual solar radiation energy reaching the Earth's surface is equivalent to about 130 trillion tons of standard coal; it is the most abundant energy available to humans. It is estimated that in the long period of 1.1 billion years, the sun consumed 2% of its own energy. In the future, it will be enough for the human beings of the earth to use billions of years. It is inexhaustible and inexhaustible. It is estimated that the total amount of wind energy in the world is about 130 billion kilowatts, and the total amount of wind energy in China is about 1.6 billion kilowatts.
4. Wind power facilities are improving, mass production reduces costs, and wind power costs are lower than generators in appropriate locations. Most wind energy facilities are not three-dimensional facilities, which can protect land and ecology.
