Power generation methods include: thermal power generation, hydropower generation, nuclear power generation, wind power generation, geothermal power generation, etc.
Power generation refers to the production process of using power generation devices to convert raw energy such as water energy, thermal energy of petrochemical fuels (coal, oil, natural gas), nuclear energy, etc. into electrical energy.
Power generation is used to supply the needs of various departments of the national economy and people’s lives.
Nowadays, fossil fuels are still used as the main form of power generation, but fossil fuel resources are not many and are becoming increasingly depleted. Human beings have gradually begun to use solar energy, wind energy, geothermal energy, ocean energy and other energy sources to generate electricity. Generate electricity.
Including electricity, heat, liquid fuel, gaseous fuel and properly processed solid fuel, etc.
Electricity is the most important secondary energy, which includes thermal power generation, hydropower generation, nuclear power generation, wind power generation, solar power generation and other forms. Electricity is the most convenient and clean energy, which can be used in various fields, such as industry, agriculture, transportation, commerce, etc.
Heat is also an important secondary energy source, which can be converted through the combustion of fuel or renewable energy sources such as geothermal energy and solar energy. Thermal power is mainly used for heating, industrial process heating, etc.
Liquid fuels and gaseous fuels are also important secondary energy sources. They are usually processed from primary energy sources such as oil and natural gas. Liquid fuels such as gasoline and diesel are mainly used in the transportation field, while gaseous fuels such as natural gas are mainly used for household and industrial gas.
Secondary energy also includes properly processed solid fuels, such as coal tar, charcoal, etc. These fuels are usually used in special areas or for specific occasions.
Applications of secondary energy:
Electricity is the most important type of secondary energy. It is widely used in industry, agriculture, transportation, Business and other fields. In the industrial field, electricity is the main power source for production activities such as factories and mines. All kinds of mechanical equipment require electricity to drive. In the agricultural field, electricity provides power for irrigation systems, greenhouses and other facilities, improving the efficiency and yield of agricultural production.
In the field of transportation, electricity provides power for urban transportation, railways, aviation, etc., and promotes the development of transportation. In the commercial field, electricity provides necessary energy such as lighting, refrigeration, and heating for various commercial facilities.
Heat is also a widely used secondary energy source. It is mainly used in areas such as heating and industrial process heating. In the field of heating, heat provides warmth and heating functions for buildings and protects people's living environment. In industrial process heating, heat provides necessary heat for various industrial production processes and promotes industrial development.
Liquid fuel and gaseous fuel are also widely used secondary energy sources. Liquid fuels such as gasoline and diesel are mainly used in the transportation field, while gaseous fuels such as natural gas are mainly used in the transportation field.It is used in fields such as household gas and industrial gas.
