How many types of power generation are there? What are the disadvantages and advantages?

The main power generation methods are: wind power generation, hydropower generation, nuclear power generation and thermal power generation.

1, wind power generation

Advantages: renewable energy, environmental protection;

Disadvantages: limited by geography and climate.

2. Hydroelectric power generation

Advantages: environmental protection, saving primary energy;

Disadvantages: the water source cannot be guaranteed and is limited by geography and climate.

3. Nuclear power generation

Advantages: high energy density of nuclear fuel, small volume of fuel used and convenient transportation and storage;

Disadvantages: Nuclear power plants will produce high-grade radioactive waste, with low thermal efficiency and serious thermal pollution.

4. Thermal power generation

Advantages: low cost and mature technology;

Disadvantages: polluting the environment and consuming primary energy.

Extended data

By the end of 1980s, the main forms of power generation were hydropower, thermal power and nuclear power. Although there are many other forms of energy production, they are not large in scale.

The status of these three main forms varies with the energy composition of different countries. The world is dominated by thermal power generation, which accounts for more than 70% of the total power generation. The proportion of thermal power in Japan and Germany is above 60%. Norway, Sweden, Switzerland, Canada and other countries mainly use hydropower.

Among them, hydropower in Norway and Switzerland accounts for about 90% of the total power generation, more than 70% in Canada and more than 60% in Sweden. Finland and Yugoslavia each account for 50% of hydropower and 50% of thermal power. France is dominated by nuclear power, and its power generation accounts for more than 70% of the total power generation.
