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.
Water can produce electricity.
The basic principle of hydroelectricity is to use the difference in water level to produce electricity with a hydroelectric generator, that is, the potential energy of the water is converted into mechanical energy of the water wheel, and then into mechanical energy. mechanical energy is used to drive the generator to obtain electricity.
Scientists take advantage of natural conditions of water level difference, effectively use flow engineeringides and mechanical physics, and carefully combine them to achieve the highest power generation capacity, so that people can use cheap and pollution-free electricity. . Low-level water absorbs sunlight and circulates water throughout the earth, restoring the high-level water source. In 1882, the first recorded application of hydroelectric power took place in Wisconsin, United States. So far, the scale of hydroelectric power ranges from micro-scales, tens of watts used in rural areas of the third world, to millions of watts used to power large cities.
