Advantages and Disadvantages of Wind Energy
Advantages of Wind Energy
Clean & Environment friendly Fuel source:– It doesn’t pollute air like power plant relying on combustion of fossil fuel. It does not produce atmospheric emissions that cause acid rain or green house gases (carbon dioxide (CO2) or methane (CH4)). Noise and visual pollution are both environmental factors, but they don’t have a negative effect on the earth, water table or the quality of the air we breathe.
Renewable & Sustainable:– Winds are caused by heating of atmosphere by the sun, earth surface irregularities and the rotation of the earth. For as long as the sun shines the wind blows, the energy produced can be harnessed and It will never run out, unlike the Earth’s fossil fuel reserves.
Cost Effective:– Wind energy is completely free. There’s no market for the demand and supply of wind energy’s, It can be used by anyone and is one of the lowest price renewable technologies available today, depending upon the wind resource and the particular project’s financing.
Industrial and Domestic Installation:– Wind turbines can be built on existing farms or ranches where most of the best wind sites are found. Wind turbines uses only a fraction of the land which causes no trouble in work for the farmers and rancher, providing landowners with additional income paid by the owners of the wind power plants. Many landowners opt to install smaller, less powerful wind turbines in order to provide part of a domestic electricity supply.
Job Creation:– Jobs have been created for the manufacture of wind turbines, the installation and maintenance of wind turbines and also in wind energy consulting. According to the Wind Vision Report, wind has the potential to support more than 600,000 jobs in manufacturing, installation, maintenance, and supporting services by 2050.
Disadvantages of Wind Energy
Fluctuation of Wind and Good wind sites:– Wind energy has a drawback that it is not a constant energy source. Although wind energy is sustainable and will never run out, the wind isn’t always blowing. This can cause serious problems for wind turbine developers who will often spend significant time and money investigating whether or not a particular site is suitable for the generation of wind power. For a wind turbine to be efficient, the location where it is built needs to have an adequate supply of wind energy.
Noise and aesthetic pollution:– Wind turbines generate noise and visual pollution. A single wind turbine can be heard from hundreds of meters away. Although steps are often taken to site wind turbines away from dwellings. Many people like the look of wind turbines, others do not and see them as a blot on the landscape.
Not a profitable use of land:– Alternative uses for the land might be more highly valued than electricity generation.
Threat to wildlife:– Birds have been killed by flying into spinning turbine blades. However it is believed that wind turbines pose less of a threat to wildlife than other man made structures such as cell phone masts and radio towers. Most of the problems have been resolved or greatly reduced through technological development or by properly siting wind plants.
