The Brief Introduction of Electric Power



The electrical power is a kind of energy whose power is electric energy. It had been invited within the 1870s. Its invention and application brought about the second high tide of industrialization. Simultaneously, the invention continues to be one of the three technological revolutions in the world. From then on, people's life has been changed by the science. The large-scale electric power system in the 20th century is one of the most critical achievements in the scientific good reputation for the human engineering. It is the power generation and consumption system that's comprised of sections such as power generation, power transmission, power transformation, power distribution and power utilization. This technique transforms the primary energy source within the nature in to the electric power with the electrical power unit. It supplies the electrical capacity to the users through transmission, transformation and distribution.

There are plenty of types of ways of electric power generation. For instance, it can be generated through the thermal power, solar power, wind power, nuclear energy, hydropower and so on. every way has its own demerit and isn't ideal. Within the follow passage, they'll be introduced in detail. What comes first is thermal power generation. At present it is not a well known way, since it easily leads to the serious problems, such as smoke pollution, dust pollution and resource consumption. When it comes to hydro power, it's also not so ideal. It's possible submerges a lot of lands as well as will result in the ecological damage. Besides, the water power resource in the united states is restricted and often is influenced by the times of year. If the reservoir is affected with the breakdown, it's hard to image the result. The 3rd way introduced in the article is wind power generation. It's a type of noise and visual pollution. In addition, in order to build the wind power station, lots of lands and forests is going to be occupied, with a bad effect on the vegetation cover. Meanwhile, the power generation continues to be not stable and uncontrollable. Fourthly, the electrical power could be generated by the nuclear energy. In the normal situation, the nuclear power is quite clear. But when the nuclear leakage happens, the result is very terrible. Lots of radioactive materials will be released, that is very harmful for that environment the ones. Besides, the cost of the nuclear energy station is extremely high. Therefore, how to choose the right way for electrical power generation is a very important issue. It is suggested for people to think about every part carefully.

Although it is now the internet era, the requirement for the electrical power continues to be increasing, because we invite many electric products for example computer, household electrical appliances and so on. There is on doubt using the growth and development of the new technology, the electrical power has been the essential part of our life.
