Is the electricity produced by hydroelectric plants clean energy?

Hydropower is not a clean energy source and has the following aspects:

1. The flow of water from the reservoir slows, causing eutrophication and other water pollution incidents. Large areas of land submerged by reservoirs can also become sources of water pollution.

2. The dam cuts the river, affecting the growth of aquatic life and affecting the spawning of some migratory fish. ?

3. Recent studies have shown that reservoir water bodies will release large amounts of greenhouse gases such as carbon dioxide and methane, and that hydropower is not a low-grade energy source in carbon.

4. Others: reservoir-induced geological disasters, environmental pollution during the relocation process, etc.

The high school said that hydroelectricity is a clean energy, I think it's because we compare it tothermal energy, etc. On the other hand, it is often said that "hydropower is a renewable and clean energy source", but it is rarely said that hydropower is a completely clean energy source. As learning deepens, knowledge must be modified and concepts must change. I don't think the high school textbook teacher would be that stupid. Furthermore, so-called hydropower is not about clean energy. First, hydropower has shown enormous economic and ecological benefits since the Tennessee project began. As a clean energy source, it has even spurred enormous regional economic development.

I think that not only is it entirely possible, but depending on the height of the water height of the tank, if the energy is generated several times of result, not only the original potential energy but also a greater cin energyethics will exist. If you want to get the best results, you need to change the turbine design and connect it to pressure lines, as well as a whole new set of new solutions.
