Brief introduction of electric power
Electricity is an energy source driven by electric energy. It is found that in the 1970s of 19, the discovery and application of electric power set off the second industrialization climax. It has become one of the three major scientific and technological revolutions in the world since the18th century in human history, and technology has changed people's lives since then.
The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, transmission, substation, distribution and electricity consumption. It converts the primary energy of nature into electric energy through mechanical energy device, and then supplies power to users through transmission, transformation and distribution.
Today is the era of the Internet, and our demand for electricity is still growing, because we have invented more products that use electricity, such as computers and home appliances. It is undeniable that the constant emergence of new technologies makes electricity a necessity for people.
Power generation methods mainly include: thermal power generation (combustible materials such as coal), solar power generation, large-capacity wind power generation technology, nuclear power generation, hydrogen power generation, water conservancy power generation and so on.
Energy science in 2 1 century will create brilliant achievements for human civilization. For example, a fuel cell is a chemical power source that directly converts the chemical energy of fuels such as hydrogen, natural gas, coal gas, methanol and hydrazine into electrical energy. Biomass energy is based on biomass, and the technology of efficient and clean utilization of biomass energy has also been greatly developed.
