16. The advantages of renewable energy production such as wind power and photovoltaic power generation in the power system are as follows:
1. Solar energy resources are inexhaustible and are widely distributed across the earth. Photovoltaic power generation systems can be used anywhere there is light and are not limited by factors such as region and altitude.
2. Solar energy resources are available everywhere and can be used to provide electricity nearby without having to transport them over long distances.
3. The energy conversion process of photovoltaic power generation is simple. This is a direct conversion of light energy into electrical energy. There is no intermediate process or mechanical movement, and there is no mechanical wear.
