How Much Does A Wind Turbine Cost?
December 1st, 2009 | 
Author: Electricity-generating wind turbines have been widely used for about a century now, and they’ve been improving all the while. Perhaps more importantly, their cost has steadily decreased. Wind turbines generally fall into a few basic categories, each of which is intended to serve a specific need and will likely be more or less appropriate in relation to the prospective buyer’s requirements.
Large, commercial wind generators, which have been in use since about 1930, are one category which has developed significantly in recent years. Some of the areas in which they’ve improved include: blade design, which makes perhaps the biggest difference in terms of how a wind turbine operates; dependability, which is important for a machine you intend to have active 24/7; and efficiency, generating more output even with less wind. This variety of wind generator is different from residential-use turbines in that it’s built from stronger and heavier materials, as it’s normally used to handle higher winds.
As the strongest and most consistent winds are usually in remote areas such as shorelines, large-model wind turbines normally need to be located in these areas. Being “out of the way” like this means that it would be expensive to have to repair them all the time, so it’s necessary that these models are built to last. Large-scale turbines often exceed 0,000 in price, which is due in large part to these factors.
Wind turbines for residential use have become more popular in recent years. The main problem encountered by early wind turbines for residential use was that they couldn’t adjust smoothly to shifting wind patterns, which are particularly common due to the buildings and other obstacles that are typical of residential settings.
Early models were also prohibitively heavy. It would usually be necessary to have a special support structures in order to use them. Most homeowners found these early models too costly and limited in function to meet their needs.
Micro turbines, the most recent phase in the development of residential-use wind turbines, rectify the problems that plagued earlier iterations. The most welcome improvement with these units is their capacity to produce power from lower winds, which makes them effective even without being mounted on towers. Some owners even set up micro turbines directly on the roof. Although compact units like these aren’t able to generate the same amount of power as large-scale turbines, they make up for this by turning constantly. With a price range of about 0 to ,000, these micro turbines are also relatively inexpensive and are well within the range in which the electrical bill savings they provide will almost immediately justify the investment
The price of a wind turbine is generally contingent upon factors like size and capacity. By building your own wind turbine, you can bring the cost down even more. Though it might sound like a big project, anyone can learn to build a wind turbine with the right instructions, and this will allow them to save a lot of money and get free electricity for life.

Wind Turbine
Although solar power may be getting the most attention among renewable energy sources, when it comes to generating power, wind power is another viable option which may actually be superior in a number of situations. Today’s efficient, quiet and compact wind turbine systems can be a good option for just about anyone who’s looking to reduce their monthly electricity bills. Wind turbines can turn any location that has a breeze into a power generating area.
Some homeowners are even building their own wind turbines. This option is much more affordable. Once you’ve got the right components and a design, you can make a wind turbine in just a weekend. Do you want to know the price range of the different types of commercial wind turbines? You can check out wind turbines cost for futher information.
All it takes to put together a wind turbine are some technical skills and some simple tools.
There are a few basic components that are required for building a wind turbine. You won’t have any difficulty finding any of the parts you need to buy, and there are some parts you might already have on hand. All wind turbines have rotor blades, a generator, and sheet metal to mount the unit on.
The most important components of any wind turbine are the blades and rotor assembly. This is the part of the turbine that collects the wind and rotates. Different sources offer instructions for building rotor blades, which can be done using PVC pipe. This doesn’t take professional-level mechanical skills, either.
The next step is to find a suitable generator. Generators can sometimes come in surprising forms; the main component is a motor, even if it’s been salvaged from a completely different type of appliance. Motors that can produce electricity when rotated are appropriate for this purpose.
Once you have all of these parts, all that’s left is to set the rotor and blades on one end of a platform and join the shaft from the rotor to the shaft on the generator. For the greatest amount of free energy possible, set up the wind turbine in the best available place in terms of wind velocity and consistency.

Advantages and Disadvantages of Wind Power
Residential wind turbines are a great way to generate energy, thanks to advancements seen in recent years. New materials and technologies have enabled newer designs for residential wind turbines, and these in turn generate even more power from less wind than ever before. Furthermore, there are all kinds of styles and sizes of residential turbines on the market now, and homeowners are certain to find one that meets their requirements in terms of size and power.
Benefits
Endless energy
The wind will never stop. There’s no limit to the energy the wind can provide. Fossil fuels can’t make that claim. Non-renewable sources of energy including oil, coal and natural gas are just that – non-renewable. Once they’ve run out, there won’t be any choice but to start using other sources of energy. Decreasing reserves mean increasing costs, and the endless nature of wind means that its price remains constant, and therefore more and more attractive by comparison.
Energy without the bills
If you’re using wind energy, you won’t have to worry about kilowatt hours or anything like that. After the one-off cost of installing a wind turbine, you have permanent, free power. The previously impossible goals of going off the grid and saying goodbye forever to electric bills are now widely available with the use of residential wind turbines.
Clean energy
In addition to financial costs, you can also eliminate environmental costs by using wind power. The same can’t be said of fossil fuels, which constitute a serious threat to the environment in current usage quantities. You can reduce your carbon footprint significantly by using wind energy instead.
A truly domestic energy source
It’s often said these days that dependence on foreign oil is a serious problem for our country in terms of both security and economics. Electricity produced by wind turbines directly replaces energy that is derived from foreign oil, and therefore it can have a significant effect in terms of lowering dependence.
Energy at all times
One of the advantages that wind power has over solar power is that it can generate electricity for the home day or night and in any weather. As useful as solar panels are, they have the disadvantage of requiring sunny conditions. On overcast days, or at night, you’ll need an additional energy source, such as electricity stored in batteries or purchased from outside providers. These restrictions don’t apply to wind energy.
Any home configuration works
Solar power systems are held back by the fact that they require significant sun exposure in order to work at peak efficiency. For homes that have a lot of shade, or lack sufficient southern exposure on the roof, this can be a problem. A wind turbine isn’t affected by the same restrictions. Furthermore, a wind turbine takes up less total space than solar panels, while producing the same amount of power.
Disadvantages
Startup cost
There’s no doubt that the installation cost of a wind generator can be very high. In the long run, though, the free electricity that comes from a wind turbine will more than offset the initial cost. If you’ve got the know-how, some common tools, and some free time, you can even put together your own wind generator, which will make the entire process even more sensible from a financial standpoint. If you’re interested take a look at wind Generator Plans.
Height requirement
If you’re using a larger type of wind generator, you’ll need to be certain that it’s set up high enough to experience consistent, strong wind. Depending on the surrounding tree line and buildings, this can be very high. Wind generator users who are located in areas with many tall buildings or trees occasionally need to mount the generators on towers. The HOA permits or approvals that may be necessary in order to carry this out can add to the overall cost of installing a wind generator. Though, again, building a homemade wind turbine will help lower the cost.
Wind needed
Wind generators work best in areas with consistent wind. Of course, the more wind, the better. In other words, the fewer buildings and trees are present in the area, the better it will be for wind energy generation. Even though you can deal with these difficulties by making use of a tower, it is most efficient to produce wind energy in areas without these obstalces. A DIY guide will teach you how to build a wind turbine.
These are the benefits and drawbacks of wind power. For most people, the disadvantages end up being pretty insignificant in comparison to the advantages. Even solar power can’t compete with wind power when it comes to generating consistent power. Where solar power may suffer somewhat, wind power truly shines. Solar and wind power do share the common drawback of being costly to install. Perhaps the best way to deal with this problem, if you find the expense is discouraging you from moving forward, is to build your own wind generator.
