Wind Energy: Advantages and Disadvantages
Advantages and Challenges of Wind Energy. Advantages of Wind Power. Wind power is cost-effective. Because the electricity from wind farms is sold at a fixed price over a long period of time e.
Wind creates jobs. The U. Wind enables U. It's a clean fuel source. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas, which emit particulate matter, nitrogen oxides, and sulfur dioxide—causing human health problems and economic damages. Wind turbines don't produce atmospheric emissions that cause acid rain, smog, or greenhouse gases.
Wind is a domestic source of energy. The nation's wind supply is abundant and inexhaustible.
The advantages and disadvantages of wind power
It's sustainable. Wind is actually a form of solar energy. Although wind energy qualifies as a renewable resource, wind speeds fluctuate each day. This can be a big disappointment to wind turbine developers who will commit every penny and every ounce of energy in the project only to end up with fluctuating wind patterns. This is why developers must do their research first to pinpoint the best location for setting up turbines before actual installation.
The best location must have sufficient supply of wind. Higher elevations are preferred since the higher up you go, the stronger the winds. A lot has been done to bring down the cost of installing turbines; the overall costs, however, remain on the higher side. The first step to installing a turbine is usually to do a rigorous survey to determine the winds speed of the location.
This involves erecting a sample turbine to gauge the wind speeds over a stipulated period. If the location is found to be ideal, the wind turbine will be manufactured and transported to the site and set up on a strong foundation.

The entire process adds up to the cost of setting up a wind turbine. When talking about offshore wind turbines, the cost becomes more pronounced. Some firms even go to the extent of commissioning bespoke ships with the ability to transport and install wind turbines at sea. Although wind turbines come with eye-catching designs, they impact the natural beauty of the landscape. When a lot more wind turbines are set up, the area becomes unsightly.
The local community starts to sound alarm bells, and this can escalate to a conflict. Though many people believe that wind turbines actually look nice but majority of them disagree. People consider wind turbines to have an undesirable experience. Petitions usually come in court before any proposed wind farm development but few people think otherwise and feel they should be kept in tact for everyone to enjoy its beauty.
Wind turbines are particularly disadvantageous to the local bird species. A lot of bird death as a result of collision with turbine blades has been reported in these areas. This can wipe out the population of certain bird species. Also, wind turbines require them to be dig deep into the earth which could have negative effect on the underground habitats.
However, there has been an influx of bladeless wind turbines in the marketplace designed to reduce bird deaths. This could be a game changer for turbine manufacturers. The most hated disadvantage to wind turbines is the noise they produce.
Disadvantages of Wind Energy
The sound produced by one turbine can be perceived from far distances. Combine many turbines, and the noise becomes unbearable. Although the emphasis is to site wind turbines away from the local community, most companies disregard this rule. This explains the strong public objections to wind turbine installations in most areas. The visual pollution is another reason why people do not find it attractive to install it in their backyard.

The best location of wind turbines can be the most fertile land where farming is practiced. Installation of wind turbines would take away land that has been the bedrock of agricultural activities for many years. In the last couple of decades, the frequency of tornadoes, hurricanes and cyclones have increased considerably.
Disadvantages of a Vertical Axis Wind Turbine
Now these severe storms can cause extensive damage to the wind turbines and can be a safety hazard to the people working in these wind farms. The damage may cause huge damage to wind turbines. Therefore, countries that do not have any coastal or hilly areas may not be able to take any advantage of wind power. The location of a wind power system is crucial, and one should determine the best possible location for wind turbine in order to capture as much wind as possible. Just like solar energy which relies heavily on sun to produce power, wind energy needs high speed winds to produce power on constant basis.
