How many ways are there to generate electricity? How do they generate electricity?

One of the main ways of generating electricity: wind power, hydroelectric power, nuclear power, thermal power

Two of the advantages of wind power: renewable energy, environmental protection. Disadvantages: limited by geographical and climatic constraints.

Nuclear power generation advantages:

1. Nuclear power generation will not cause air pollution, will not produce carbon dioxide aggravate the earth's greenhouse effect.

2. Uranium fuel used in nuclear power generation has no use other than power generation.

3. Nuclear fuel has high energy density and the fuel used is small in size, making transportation and storage easy.

Disadvantages:

1. Nuclear power plants produce high and low order radioactive waste.

2. Nuclear power plants are less thermally efficient and have more serious thermal pollution.

3. Nuclear power plants are not suitable for peak and off-peak operation.

Thermal power generation Advantages: low cost, mature technology Disadvantages: environmental pollution, consumption of primary energy

Hydroelectric power generation Advantages: green, save primary energy Disadvantages: water source can not be guaranteed, the cost is higher than that of thermal power

Hydroelectric power generation is the most efficient way to generate electricity, and it is the most cost-effective way to generate electricity.
