The Advantages and Disadvantages of Wind Power


Although wind power has many advantages, it does come with some human and environmental disadvantages.

The ever-intensifying drive to discover clean, renewable energy technologies has in recent years led to wind power developments beyond the lab and the drawing room and into the real world.

Here we’ll explore the advantages and disadvantages of wind power.

Wind farms now produce 3.2% of the energy used in the US, 9% in Germany, 17% in Portugal and an astounding 26% in Denmark.

Far from an experimental technology, wind power has begun to prove itself as a real solution to our ever-growing energy needs. Wind farms the world over are right now powering homes and businesses in many countries, and its proliferation seems assured.

However, that’s not to say that wind power is a perfect solution. As with all means of energy production there are advantages and disadvantages of wind power that need to be considered, not only by the people who design and build our energy production facilities but also by we who use them.

Advantages of Wind Power

Wind Energy as Green as Can Be
There are no forms of energy that are truly ‘green’. While solar, wind and hydroelectric power produce no emissions once the facilities are in place, the production and installation of those facilities come with their own set of costs.

However, the environmental cost of building and operating wind turbines is a fraction of the cost of any other traditional means of power generation. While coal- and oil-fired power stations continue to pump out emissions throughout their lifetimes, once wind turbines have been installed their ongoing carbon footprint drops to zero.

In fact, a modern wind turbine will reach its ‘break even’ point just 8 months after installation. This means that a turbine will produce enough clean power in 8 months to counteract the carbon footprint of its construction.

Cost advantages of wind power

An even more compelling case for wind power is that, once the turbines have been built and installed, a wind farm will produce energy at essentially zero cost as long as it is properly maintained. No fuels need to be mined, transported and burned, with minimal costs for staffing and maintenance.

Beyond these costs, a turbine will generate energy that becomes cheaper and cheaper with each Watt produced.

Wind Power Can Go Anywhere

While some locations will offer greater efficiency than others (based on local wind patterns), one of the major advantages of wind turbines is that they can be installed anywhere wind currents are present.

We could fill deserts, the countryside and even oceans with countless turbines to take advantage of the 250 terrawatts of potential global wind energy – many times the global demand.

Wind power isn’t limited to sprawling wind farms, either. All of us can install turbines in our own homes to supplement our energy needs (or even become completely self-sufficient). At a relatively low cost we could increase wind power production to many times its current capacity.

Disadvantages of Wind Power

A Threat to Wildlife

In the early days of wind power there was great concern about the effect wind farms would have on wildlife, especially birds. Birds made a habit of colliding with the blades of the turbines, and many even built their nests in the structures themselves.

While bird strike is still a problem for wind farms, it’s not nearly as severe as it was in the past. Modern turbines operate at a higher efficiency than the earlier models, providing the same power while the blades spin at a much lower RPM. Towers have also been redesigned to prevent birds from nesting, with smooth surfaces replacing the old girders.

This concern, then, is more of a design challenge than an intractable problem. With the right design, the effect on local wildlife can be kept to a minimum. Furthermore, it’s worth remembering that most other forms of energy production have a much greater impact on wildlife, and even power lines are much more dangerous for bird life than wind farms.

Predicting Power from Wind Turbines

One of the major problems with wind power is the unpredictable nature of the raw material: wind. While traditional power stations can control their production at will, wind turbines depend on the local air currents to keep producing energy. When the air is still the blades don’t turn, and power production drops to zero.

To solve this problem we must locate our wind farms in areas with strong, dependable air currents that rarely fluctuate. Offshore locations usually provide strong winds, as do hilltops and other exposed areas. As long as we never reach the point at which we depend entirely on a constant air flow to maintain our power requirements this needn’t be a serious problem.

Wind Farms Are an Eyesore

One of the most bizarre complaints (considering the benefit they bring) is that wind turbines are unattractive and spoil the landscape.

This is an understandable complaint, but it seems odd to complain about a wind farm when we have for many years erected endless pylons and power lines across even our most beautiful landscapes.

This is a problem that should resolve itself on its own. In time people will become accustomed to the sight of wind turbines, and they will be ignored just as we ignore power lines. The only alternative, it seems, would be to locate our wind farms far from human habitation, which would cause more problems than it solves.

Blowin’ in the Wind – Overview of the Advantages and Disadvantages of Wind Power

While wind power isn’t an ideal solution to our energy needs, the pros far, far outweigh the cons. An endless supply of clean, renewable energy that can be produced cheaply and easily is the Holy Grail of energy production. Wind power can provide it, so long as we can learn to accept the few small disadvantages that come with such an abundant supply of power.

    • Very much dependent on the spicefic engineering of the wind turbine. You are losing energy to friction, so the mechanics of the device are very important. All of that is not a consideration for fossil fuels becase the earth has done most of the conversion already by using gravity (i.e., pressure), which is basically infinitely available. If you are thinking not in terms of energy cost, but financail cost, then you really need to think about the supply chain. A single high-effeicncy wind turbine might cost $5MM to build, but there is operational cost, land cost, distribution and storage costs. All of that is baked into the end user price of a gallon of processed fossil fuels. I don't know the spicefic numbers, but I do know that none of the wind farms would be profitable without the government subsidies that they are getting ATM.That chart of 1996 California date someone posted showing that wind is the lowest cost seems highly suspect to me at a minimum it is looking at regulatory compliance costs for things like nuclear and fossil feuls, not just the cost of generating and delivering the energy. That is the problem with data "sound bites", they are a little to easy to quote without thinking about them.

    • The wind milles may definitly spoil the landscape if they are located without knowledge and feeling about the surroundings where they are located. You shall always have in mind that the wind farm may have an impact on the environment, and avoid unique areas with high values for peoples well being and/or other activities.
      I think that wind power is a part of our future but you have to consider other values and make compromises when developing new sites. The best location (most efficient) for the windfarm is not necesseraly the best location considering other values in a society, also in an economic point of view.


      • We moved into an area where we did not know and were not informed by annyoe that a wind farm was planned in the near future.It is beyond comprehension. And people bitch about enhanced interrogation .Come live in my front yard for a while and see what deprivation,constant annoyance and just plain disgust does to you over a period of time.It ain't pretty and it sure as hell is not the place in the country I hoped it would be!It is all a farce, lies and deceitfulness.Tasteless, lame and weak !

  • There is something beyond bird strikes. There are genuine advantages and eco-benefits of offshore wind turbines and farms, pollution, emission free and economic. But what about the marine environment and marine ecosystem? Does anybody care? Corporates never care about the planet except profit. Have anyone looked at the disadvantages of offshore wind turbine farms? no doubt they are better than coal fired or nuclear power plants, but may be damaging to the ocean ecosystem. Fresh water fish and marine aquatic could be in the peril if all the wind turbines are to become seaborn in future. and just imagine the ugly look at the ocean you will see only turbines spring up. We need energy and power, no doubt, but let us not become powerful enough to destroy the marine ecosystem, already reeling under heavy pollution from oil spills and industrial pollutants. Going for the alternative is good, but only if such alternates does no compromise our ecosystem further. This is a voice for concern, but these idiot engineers always ignore such (half-knowledge) unless a catastrophe occurs.

  • One disadvantage regarding wind power, impact on health. The negative impact of turbines over 100 feet on people within 1/4 to 1/2 mile of the turbines is bad, indeed. Headaches, inability to sleep, the "humm" of the turbines interrupts sleep and causes problems, the "flicker" effect and dizziness has also been reported by people in the US, Canada, and Europe.

  • you know... if we install a wind energy at our home and there are no wind around... can't we just spin it ourself? just wondering

  • this helped me lot and lot much in finishing the paper presentation thank you than you thanks to this website
