11 Wind Power Pros and Cons
Today, wind power has a immersive effect in the world. Its reason is to be renewable energy source. Especially, From being renewable to being contemporary, there are plenty of advantages of using wind power. But, every rose has its thorn. Before diving into the wind energy production, you have to know its disadvantages as well. We’ve listed some of the most important pros and cons of wind power for you.
While there are many advantages of using wind power as a renewable energy source, there are also a few disadvantages of using wind power.
Chiefly, wind dependency and sound pollution are the fundamental disadvantages of wind energy. Nevertheless, we can avoid these issues as long as we take some precautions.

Pros of Wind Power
Clean Energy Source
As you can guess, wind energy is a clean energy source. Unlike conventional energy sources, using wind power for producing energy does not pollute the air. Moreover, it does not require any kind of destructive chemicals. Using wind power to produce energy is clean because the energy is harnessed from the wind.
Renewable Source of Energy
Wind is a renewable source and it is free to use. Most particularly, if you are living in an area that gets a lot of wind, you can get the most value out of it. In comparison with non-renewable sources, the wind is unlimited and it is a renewable energy source. The cost of producing energy from wind power reduced significantly due to the new inventions on windmills. This resulted in low-cost windmill production. According to the experts, the windmill prices will continue to fall. Put it differently, using wind power is getting fruitful day by day.
Several wind turbines can provide energy for many homes. Aim of the wind turbines is to generate electricity. Also you can look at the how do wind power work. By the way, you don’t have to buy or build a windmill to get the advantages of it. You can also buy your power from a company which sells wind energy for a particular area. Thanks to this option, you don’t have to invest in windmills and you can still get the low-cost advantages of wind power.
Extra Savings for Land Holders
There are several reasons to invest in wind energy if you are a landholder. By renting your land, you can earn a considerable amount of extra money. There are some government organizations which can rent your land to install their wind turbines. Indeed, in some cases, the electric company may end up owe to you. If you generate more power than you need from wind energy, it might go into the general electric matrix, which concludes to earn some extra cash.
Huge Potential and Rapid Growth
In the last decade, the wind energy industry has seen enormous growth. According to the U.S. Department of energy, wind power caliber has increased by an average of 30% per year.
For the total worldwide electricity production, wind power meets 2.5% of all energy demands. Either a powerful one or a smaller one, proceeding into wind energy is getting profitable day by day. Due to the current data on wind energy production, it is not hard to predict the bright future of wind power.
Cons of Wind Power
1- Wind Dependency & Uncertainty
As you can guess, unlike the weather forecast, guessing the wind is quite unclear. Some days will be windy, and some days will not. Most of the time, wind turbines work on 30% load. Which means they need more wind velocity to work effectively. Also, some bad weather conditions can also reduce energy output. You might even wind up without power or you might need an electric company to compensate for those bad weather conditions.
To sum up, the wind is unpredictable and wind energy is changeable. Because of that, wind energy may not be suitable for a base load energy source.
Bad weather conditions and/or rough winds can cause damage to the wind turbine, particularly to the blades. A broken or malfunctioned blade of a wind turbine can risk the people that living or working nearby. These blades or even wind turbine may fall on the people nearby and cause damage to them, even loss of lives may occur.
The bad weather conditions are not the only factor that creates a security risk, for example, an earthquake can also occur and the consequence of it can be devastating.
3- High Cost
Setting up a wind turbine is expensive. To be able to produce energy from wind, a wind turbine is not the only component you need. You also need other supplies. When we gather them up, the total cost of producing energy from wind is costly. Based on where you live, you may also have difficulty in finding providers to buy these wind power components.
However, wind energy is a good investment. Because, once you install the wind turbines, you produce free energy. Of course, there will be certain maintenance costs, but the amount of energy produced is sufficient to pay off these costs. The period of return of the investment varies according to the annual wind data of the region where the wind turbines located. In general, the return of the investment in wind turbines varies between 5.5 and 7 years.
4- Noise and Visual Pollution of Wind Turbines
The noise problem of wind turbines is a serious setback for wind energy. The wind energy sector worldwide requires the wind turbines to be built as close as possible to people’s homes, for the sake of profit, by ignoring the knowledge of sleep disturbance and serious health problems directly caused by the pulsed wave-wave and low-frequency noise generated by the wind turbines. For detailed information, you can check up on Wind Turbine Syndrome.
However, thanks to the latest developments in technology, a modern wind turbine now emits no more noise than a refrigerator, at a distance of 300 meters. So much so that the sound of wind blowing in the quiet countryside is generally higher than the sound of turbines. Nevertheless, wind turbines should be installed far enough away from nearby settlements to prevent potential disturbances. Moreover, in Spain, the engineers are working to reduce the noise of the wind turbines by adding some sort of sound absorbed to the wind blades. This sound absorbed has a jagged and special design.
As for the visual pollution, because the wind turbines are very large, they can cause visual pollution. But it is not a serious problem if we compare to the noise pollution.
5- Threat to Wildlife
Due to the construction of wind turbines, the edges of the blades is unsafe to those animals who are flying close by. For now, there is no way of avoiding it. We can solve this problem, however, by installing wind turbines in places where birds do not inhabit. Before installing a wind turbine, we wanted to let you know this problem, to see the possible consequences.
6- Suitable only for certain areas
To produce energy from the wind, the location is matter. Because the more wind you get, the more energy you produce from the wind turbine. This makes a big setback for wind energy because you have to live in a windy place.
To those who are eager to invest in wind energy, knowing the pros and cons of wind energy is crucial. Because of the latest technological development on the wind energy field, the future of it is bright. By installing a windmill in your land, you can lower your electricity bills. You can even sell your remaining energy which generated from wind to other homes. Also, buying energy from wind power companies is cost effective.
However, there are some critical disadvantages of wind energy. And we can only solve some of those problems by thoroughly working on them. Thanks to the latest technological development, the noise problem of the wind turbines is dying away day by day. But location and threat to wildlife problem are still exist. Taking into account all of these, wind power is still a good renewable energy choice. If you want there are also wind power pros and cons video.
