Electricity is produced by generators. There are many ways to generate electricity. Hydroelectric power, wind power, thermal power and nuclear power can all be used to produce electricity.
Hydropower involves building a large dam upstream of a river to block the water and use the power of the water to drive a generator to produce electricity. The daily rising and falling tide contains enormous energy. As long as you build a dam on the seaside where the tide rises and falls relatively large, build a few gates, install a turbine, use the water flow to drive the turbine, and then drive. the generator, you can produce electricity.
Thermal power generation uses oil or coal as fuel and uses the heat they generate to drive a steam turbine todrive a generator to produce electricity. Wind power uses the power of the wind to drive wind turbines to power generators to produce electricity. Nuclear power generation is the conversion of energy emitted by atomic nuclei into electrical energy.
Once the electricity is produced, it must be transported by cables before it can reach thousands of homes.
The discovery and application of electricity has greatly spared the physical and mental labor of human beings, given wings to human power, and continued to expand the tentacles of human information.
The discovery of electricity can be considered a revolution in human history, and the kinetic energy it generates is continuously released every day. It is an exaggeration to say that human demand for electricity is not less than that for oxygen. Without electricity, civilizationA human would probably still be exploring in the dark!
