What are the advantages and disadvantages of thermal, hydraulic, nuclear and other power plants?

Firepower advantages: relatively low construction costs, easy access to conventional fossil fuels, disadvantages: greenhouse and harmful gas pollution, high transportation pressure.

Hydraulic advantages: no pollution, renewable; disadvantages: strongly affected by seasonal and climatic factors, causing certain damage to the ecological environment.

Advantages of nuclear energy: no greenhouse gases are produced and the pressure of transporting the fuel is low; disadvantages: radioactivity, decommissioning and disposal are difficult, and construction costs are high.

For reference.

The difference between thermal power generation and hydroelectric power generation

(1) Hydropower production: when water (having potential energy) in high places flows to lower places, the potential energy est converted into kinetic energy. A hydraulic turbine installed in a lower part of a watercourse turns thanks to the kinetic energy of the water flow pushing the blades (mechanical energy). If the hydraulic turbine is connected to a generator, it can drive the generator to rotate. and convert mechanical energy into electrical energy. This is the principle of hydroelectricity production. Hydropower can generally be divided into electricity generation from rivers, dams (reservoirs) and pumped storage. Pumped power generation releases water from a reservoir to generate electricity during the day when electricity demand is at its peak, and uses the excess electricity to pump the water up to the reservoir at night (electrical energy is converted into potential energy) to produce electricity during the day. when electricity demand is at its peak. Advantages ---- 1. ReplyQuick turn---Simply open the water gate and feed it into the high pressure steel pipe

to start generating electricity. 2. Clean --- unlike thermal energy and nuclear energy which produces waste or waste

There are no problems or inconveniences when it comes to cooling water -- -- 1. Water dam

It is easy to cause environmental and soil and water conservation problems 2 Suitable for location

River emergency in the short term in Taiwan

Although there are many hydroelectric power plants

, the electricity generation capacity is quite low (2) Thermal. electricity generation: the use of thermal energy generated by the combustion of coal, oil, liquefied natural gas, and other fuels, allowing water to be heated and converted into steam. Under continuous heating, water is transformed into steam at high pressure and highpressure. then the energy of this high temperature and high pressure steam is used to operate the steam turbine to drive the generator to produce electricity. In addition, power generation by internal combustion engine is also a type of thermal power generation. Typically, an internal combustion engine (engine) powered by diesel fuel is used to drive a generator to produce electricity. This method of generating electricity is mainly used on isolated islands with low energy consumption, or as backup generators in buildings and factories. Advantages ---- 1. The generator set can be overloaded - when the power supply is tight

It can be overloaded without tripping easily 2. It is less affected by the region

As long as there is fuel Disadvantages of electricity production ----- 1. Air pollution problem 2. Cooling water temperature and drainage problem 3. Fuel source problem ---- especially in Taiwan

Raw materials need to be imported

The biggest advantage : zero emissions

Will not pollute the air Second: use renewable energy

Reduce costs

Different principles of electricity production, resources Different needs, different environmental impacts, etc.

1. The principles of electricity generation are different: thermal power generation uses the combustion of a fuel to produce steam at high temperature and high pressure, which drives a turbine to turn a generator to produce electricity. 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 needsresource ins: 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.

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.
