Different principles of electricity production, different resource requirements, different environmental impacts, etc.
1. The principles of electricity generation are different: thermal power generation uses the combustion of fuel to produce steam at high temperature and high pressure, and the steam drives a turbine to turn a generator. to produce electricity. Hydropower uses the kinetic energy of water in the natural water cycle and converts it into electrical energy using hydraulic turbines (or turbines) and generators.
2. Different resource requirements: Thermal power generation relies on fuel resources, such as coal, oil, and natural gas, which must be purchased and stored. Hydropower depends on water resources and there are available water sources, such as rivers, lakes or reservoirs.goodbyes.
3. Different environmental impacts: Thermal power generation will produce a large amount of emissions such as carbon dioxide, nitrogen oxides and particulate matter, causing pollution of the atmospheric environment. Hydropower is relatively clean, produces no direct gas emissions, and has some impact on aquatic ecology and fish migration.
