Wind-Generated Energy Disadvantages

McGrath Wind Farm of Excellence, we visited on 22 July, 2015, the role of the facility makes electricity from wind. The facility is located in 40 kilometers south of Lethbridge, Alberta. Then, this company established it in 1962, but the facility started in 2004. The wind-generated electricity is an electricity generating system using a wind-force. The wind power energy is accepted as the maintenance of natural environments, the energy source that it can secure of the energy security as one of the renewable energy, and wind-power plant and a wind-generated electricity device are built by many grounds. I saw it, and sail is used for the promotion of the ship for pumping and irrigation powder more a pumping windmill the windmill such as the …show more content…
It include littleness of the environmental load, consumption reduction of the fossil fuel, energy security, industrial development, job creation mainly. Then, there is the reduction effect of greenhouse gas discharges such as carbon dioxide. Also, the wind-generated electricity can anticipate improvement of the energy self-sufficiency ratio. If wind blows, generation is possible anytime including the night. However, the wind-generated electricity has some disadvantages. There is a problem of instability, uncertainty of the output electricity and adverse effects to neighboring environment to a master, and the choice of the setting place becomes particularly important. Then, it breaks down by thunderbolts and may cause the accident. Also, the wind-generated electricity may have a big influence on ecological system because sometimes a bird is rolled up in a blade and may be killed or injured. In addition, it has effect to living environment because it makes noise. Therefore, it is difficult to install the generator near a house. As a result, the place that is limited to the wind-power …show more content…
Then, it changes the direction of the rotor to the direction of the wind and go the control to brake it, and to completely stop a turn automatically when the burden to the blade including a typhoon and the storm is too strong and is dangerous. Also, the wind-generated electricity watches the state of the windmill with a phone line from the PC of the distant place, so coping that is immediate when abnormality occurs is possible because people can perform the control such as start, the stop of the windmill even if people do not go to the field. As a result, the wind-generated electricity can say that it is useful technology for
