Firepower:
Advantages: The technology is mature and the current cost is low. Low geographic environment requirements.
Disadvantages: high pollution, poor prospects for sustainable development. It consumes a lot of energy and has low efficiency.
Hydraulics:
Advantages: long history, low subsequent costs. No pollution, renewable water energy, large total water energy reserves.
Disadvantages: large capital investments and high requirements for 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 use. them.
Detailed information:
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. the enMechanical energy is used to drive the generator to obtain electricity. Scientists take advantage of the natural conditions of water level difference, effectively use fluid engineering and mechanical physics, and carefully combine them to achieve the highest power generation capacity, so that people can use an electricity cheap and pollution-free.
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, transforming the water into water vapor at high temperature and high pressure, and then use the water vapor to drive a generator to produce electricity. The general name of the method. Power plants that use coal, oil or natural gas as fuel are collectively called thermal power plants.es.

Thermal power plants and thermal power plants are two different ways of producing electricity. Their main differences, advantages and disadvantages are. as follows:
Main differences:
1. Fuel type: Thermal power plants mainly use fossil fuels (such as coal, natural gas, etc.) to generate electricity, while thermal power plants use non-fossil fuels such as nuclear, solar and geothermal energy to produce electricity.
2. Method of generating electricity: Thermal power plants generate steam at high temperature and high pressure by burning fuel to drive the steam turbine to produce electricity. Thermal power plants use nuclear or other thermal energy to generateerate directly; steam to drive the steam turbine to produce electricity.
3. Environmental impact: Thermal power plants burning fossil fuels will produce large amounts of carbon dioxide, nitrogen oxides, sulfur oxides and other air pollutants, which will have a greater impact on the use of thermal power plants; non-fossil fuels and emit fewer pollutants and less impact on the environment.
Advantages and disadvantages:
Advantages of thermal power plants:
1. Abundant fuel resources: Fossil fuel resources are relatively abundant. Thermal power plants can use these resources to generate electricity.
2. High power generation efficiency: The power generation efficiency of thermal power plants is relatively high, and can reach more than 40%.
3. Low costspower generation: The construction and operating costs of thermal power plants are relatively low.
Disadvantages of thermal power plants:
1. Environmental pollution: The combustion of fossil fuels in thermal power plants will produce a large amount of air pollutants, having a serious impact on the environment.
2. Greenhouse gas emissions: Thermal power plants emit large amounts of carbon dioxide and other greenhouse gases, exacerbating the problem of global climate change.
3. Energy consumption: Thermal power plants require a large amount of fuel and consume a large amount of energy resources.
Advantages of thermal power plants:
1. Environmentally friendly: Thermal power plants use non-fossil fuels, emit fewer pollutants and have less impact on the environment.
2.Sustainable use of energy: The thermal power plant uses nuclear energy, solar energy and other renewable energy sources to generate electricity, which has the characteristics of sustainable use.
3. High power generation efficiency: The thermal power plant uses high temperature and high pressure steam to directly drive the steam turbine to generate electricity, and the power generation efficiency is high.
Disadvantages of thermal power plants:
1. High fuel costs: The cost of non-fossil fuels is relatively high, and the fuel cost of thermal power plants is also high.
2. High Construction Costs: The construction costs of thermal power plants are relatively high and require significant capital investment.
3. Security Risks: There are some security riskswhen thermal power plants use special energy sources such as nuclear energy.
