The advantages and disadvantages of thermal power generation and hydropower generation

Firepower:

Advantages: The technology is mature and the current cost is low. Low requirements on geographical environment.

Disadvantages: high pollution, dim prospects for sustainable development. It consumes a lot of energy and has low efficiency.

Hydraulic:

Advantages: long history, low later costs. No pollution, renewable water energy, large total water energy reserves.

Disadvantages: Large investment in fixed assets and high requirements on the geographical environment. For example, southwest China is extremely rich in water resources, but the natural environment is harsh and construction is difficult, making it impossible to utilize them.

Extended information:

Power generation is to convert water energy, thermal energy of fossil fuels, nuclear energy, solar energy, wind energy, geothermal energy, ocean energy and other energy into electrical energy. At the end of the 20th century, most power generation used the method of burning fossil fuels. However, fossil fuel resources are not abundant and are becoming increasingly depleted. At present, humans have gradually used more renewable energy (water energy, solar energy, wind energy, geothermal energy, ocean energy, etc.) to generate electricity.

The basic principle of hydropower is to use the water level difference to generate electricity with a hydroelectric generator. That is, the potential energy of the water is converted into the mechanical energy of the hydraulic wheel, and then the mechanical energy is used to drive the generator to obtain electricity. Scientists take advantage of the natural conditions of the water level difference, effectively utilize fluid engineering and mechanical physics, and carefully combine them to achieve the highest power generation capacity, so that people can use cheap and pollution-free electricity.

Thermal power generation generally refers to the use of thermal energy generated when fuels such as oil, coal and natural gas are burned to heat water, turning the water into high-temperature, high-pressure water vapor, and then using the water vapor to drive a generator to generate electricity. The general name of the method. Power plants that use coal, oil or natural gas as fuel are collectively called thermal power plants.
