Electricity is electricity powered energy. Invented in the 1870s, the invention and application of power set off a second industrial climax. The history of mankind since the 18th century, one of the world's scientific and technological revolution occurred three times, since technology is changing people's lives. Large-scale power system in the 20th century is one of the most important achievements in the history of human engineering science, electricity production and consumption system consists of power generation, transmission, substation, distribution, electricity and other aspects of the composition. It nature of primary energy by means of mechanical energy into electricity, and then by transmission, transformation and distribution of electric power supply to the consumers.
Today is the era of the Internet, we still have a growing demand for electricity, because we invented computers, home appliances and other products use more power. Admittedly continual emergence of new technologies makes electricity become a necessity.
Information produced are: thermal power (coal and other combustible material), solar power, large-capacity wind power technology, nuclear power, hydrogen power, hydroelectric power and other energy science for the 21st century and create greater glories of civilization. The fuel cell is the chemical hydrogen fuel cells, natural gas, coal gas, methanol, hydrazine fuel energy directly into electrical energy of a class of chemical power. Biomass energy efficient and clean use of biomass energy technologies based on biomass as an energy carrier.
