1. Thermal power generation: Thermal power generation uses the chemical energy of fossil fuels such as coal, oil or natural gas to generate electricity. When these fuels burn, the chemical energy released by them is converted into heat energy, and then the turbine drives the generator to rotate, thus generating electricity.
2. Hydroelectric power generation: Hydroelectric power generation uses the kinetic energy of water flow to generate electric energy. The water flows through the turbine to drive the generator to rotate, thus generating electricity. Wind power generation: Wind power generation uses the kinetic energy of wind energy to generate electricity. The windmill blades are installed on the wind turbine. When the wind blows, the blades will rotate, driving the generator to rotate, thus generating electricity.
3. Solar power generation: Solar power generation uses solar energy to generate electricity. Solar panels absorb sunlight and convert it into electric energy, and then transmit the electric energy to the power grid for people to use. Nuclear power generation: Nuclear power generation uses the heat energy released during the nuclear reaction to generate electricity. The turbine drives the generator to rotate, thus generating electric energy.
The influence of electricity on human beings
1. power industry: electricity is the foundation of modern power industry, which provides power for various devices, including motors, lighting, heating and cooling. The development of electric power industry has promoted the modernization of human society and greatly improved productivity and efficiency. Electronic technology: electricity provides the foundation for the development of electronic technology. Through power electronics technology, we can manufacture all kinds of electronic products.
2. Transportation: Electricity provides power for transportation, including trams, trams and maglev trains. These electric vehicles not only reduce pollution, but also improve efficiency, making urban traffic more convenient and efficient. Communication: Electricity is the foundation of modern communication technology, including telephone, telegraph and Internet.
3. Medical treatment: electricity is also widely used in the medical field, such as electrocardiogram, electrotherapy, magnetic vibration and so on. These medical equipment and technologies make diagnosis and treatment more accurate and efficient, and make important contributions to human health. Energy: electricity can be used as a form of energy, and other forms of energy can be converted into electric energy through power converters, such as solar panels and wind power generation.
