Hydroelectricity, also known as hydroelectricity, refers to the process of using the flow of water to turn a generator and generate electrical energy. Hydroelectric technology does not require the burning of fossil fuels, does not emit pollution and is a clean energy source. In recent years, with the improvement of environmental awareness, hydropower has become one of the important energy sources for sustainable development.
First of all, hydroelectricity has the advantage of great stability. The water flow is stable and the amount of hydroelectric power produced is relatively stable. Compared with other clean energy sources such as wind power, solar power, etc., the volatility of hydropower is significantly lower, which promotes the stable operation of the power grid. In terms of electricity supplyricity, hydropower can provide a stable and secure source of energy for all of society.
Second, hydropower has a lower impact on the environment. Compared with coal and fuel oil power generation, hydropower generation does not produce waste gas, waste residues and other pollutants generated by combustion, and has less impact on the environment . Therefore, hydropower is widely considered as an important direction for sustainable development, capable of replacing traditional energy sources and achieving an environmentally friendly economy.
Hydroelectric energy also has its limits. Hydropower requires sufficient water, so if reservoir levels are low, electricity production will be limited. In addition, in the construction process of water conservancy projects, a large amount of funds and resourcesurces must be used, and the construction cost is relatively high. Therefore, hydropower generation should be planned and implemented based on a comprehensive assessment of local political, economic, environmental and other factors.
