Home Wind Turbines - Why Not Try Them?

In the United States, wind power is a huge source of alternative energy, from extensive wind farms to humble home wind turbines. The production of power by harnessing that strong breeze is second only to that which uses natural gas. In fact, a staggering 16,800 megawatts or more was produced via wind power, with about 30% of that capacity developed in 2007. In 2008, the total amount generated by home windmills would already amount to one percent of the United States' needs.

Currently, the large portion of this generation is due to commercial arrays of fans, although the portion supplied by smaller, individually owned home systems is increasing. This corresponds to the increasing number of people who realize that they themselves also need to take responsibility for the environment, and take steps to help reduce our dependence on oil and other fossil fuels. Oil and coal are still the biggest forms of fuel for generating electricity at different plants as well as fuelling automobiles, and they produce an alarming amount of pollution that increases as more and more energy is required.

In comparison to fossil fuel based generation, power generation of the breeze is much, much cleaner, producing no pollution once the turbines are installed. Most objections are relatively minor, such as some people's complaints that arrays of turbines spoil the visual beauty of landscapes on which they are installed. While this is true for most large-scale operations that indeed occupy large areas of land with manufactured blades, this is no problem for smaller, home wind turbines. Smaller scale setups, especially as technologies continue to develop, can be made more and more unobtrusive. In combination with solar panels, these small generators can, in fact, produce the large portion needed by an average household already.

These smaller blades are available commercially, already manufactured and ready for installation. There are generators that can be attached to your rooftop, while others may require their own tower. In many cases, the higher you can afford to mount your turbine, the better, with thirty feet being an often quoted suggestion. While the power these would generate is essentially free, the outlay at the start can be prohibitive - it would take some time before they pay off.

An alternative to commercial turbines is, of course, to build your own from available materials. While this would require a significant amount of know-how, in the end, you can really save a lot of money by building your own system. Home wind turbines can really prove to be wise money saving investments in the long run, especially if you can cut down on initial costs by building it the do-it-yourself way.

How to select wind turbines. What's critical

At any time we have bought service (service) or the goods, we are a consumer. Some from us, consumers search for the most high quality product irrespective of the price while others pay a few(a little,little bit) attention to the low price, usual purchases, but tend to dig deeply on what - нибудь perceived(recognized) as the big charge. Irrespective of the fact which the buyer you, we are sure, that the wind turbines will be entered in a category which will force at least some research to take place.

The turbine it will be rather probable the most considered component in your system of a wind turbine and there is a serious basis for this purpose. Something is similar to gasoline - a product with measurable quantity(amount). We place gallon of it in our vehicle, and it will be terminated by promotion of it approximate number (number(room)) of miles. Results are predicted and very reliable. You can buy it from set of sites and receive similar results, over and over again.

The wind turbines, being machine (mechanism), is very excellent(different) from something such as gasoline or a cardboard of milk. It also is very distinct from other machines (mechanisms) which we use daily. One example with which we are familiar - the automobile. The automobile - the complex(difficult) machine (mechanism) also is subordinated to refusal (failure). Some refusals (failures) - the main problem (release) such as the invalid engine. Others can take place, which is not done(made) with the motionless automobile, such as a window which is invalid, but they - still refusal (failure). Also, distinction between the bad engine and the attached window can define(determine), whether the automobile will be capable to reach(achieve) his(its) mission. It transports you from one place up to another. The automobile can be subordinated to many insignificant (younger) refusals (failures) such as the broken (broken) holder of a cup or invalid radio and still to reach(achieve) the purpose for which it is developed (is intended). Some machine problems can even take place in modern automobiles, and " добранный home " the way dies to allow the automobile to go some more miles.

The turbine at all has no ability to transfer even insignificant (younger) making refusal (failure) and still to work. For this reason, reliability - a problem (release) number(room) one. We shall use once again the automobile as an example. Typically with the automobile you would not buy the following model downwards that you really want and in also payment more for this purpose. It, apparently, was not good movement (step). Again the wind turbine differs. Why you would pay so much or more for model " 1 KB " on other machine (mechanism) " 3 KB " companies? It is less than manufacture for a lot of money? Reliability. Whether as far as good is the superficial turbine of " 3 KB " if it burns or each time when the big case of a wind takes place flies separately?

Windmill Blades - And From What They Are Made

Decades ago if you drove by a field and happened to see a windmill spinning in the wind, chances are the blades were made of wood. With new inventions and better technology today, wood is still used as material for turbine blades. The design is different however. And a lighter wood material is used, in order to carve the blade and faster speed rotation.
By knowing and understanding the different types of blades, and how they improve or decrease the effectiveness of a wind turbine, you can purchase this alternate energy source with confidence. Knowing it will meet your needs.

The most recent blade design is made of fiber-glass and epoxy resin. Although this blade is in its first stages and not yet marketed, what makes it unique is its curvature like tip. This allows it to catch low wind speeds and would be considered a good design for a wind turbine used in the Midwest.

Some turbine blades have actually been made with the raw material made for PVC piping. In strong lengthy winds they have been found to break, but inexpensive to replace.

Researchers have done experiments with several different materials for turbine blades. Weight, wind resistance, durability, speed rotation, sound output, and of course cost are evaluated. Glass has never been used in experiments although plexi-glass was tested. It failed due to not being able to withstand long periods of wind, and the sound output was ineffective.

Many materials have been tested poly foam and aluminum, to name a few more and their performance again was different. They were also found less effective.The turbine blade made of carbon fiber is light weight, and has a razor sharp edge which allows it to literally cut through the wind and makes it virtually silent. This is the material preferred and used in most wind turbine machines sold today.

Another factor evaluated was how many blades would be placed on a turbine windmill. Three blades almost instantly became the most popular. More blades seemed to increase noise and slow down the actual rotation of the turbine's propeller formation. After more research was done the concept of using more than three blades was no longer a factor.

The bigger commercialized wind turbines were more effective in putting out the expected wattage than one with six blades. This was proof that three blades were better. These turbines are as big as two football fields or more in size.

The smaller wind turbines for home use also remained with the propeller style and three blades as a result of its performance, producing the correct type of wattage expected. Carbon fiber blades in the right formation were the inventive solution for the vertical windmill and the wind turbines of today. The wind turbine blades as a whole are simply part of their design, an important part to the quality of performance of the entire wind turbine machine.

How To Make Solar Panels

Learning how to make solar panels was something that we decided to do as soon as we investigated the price of new solar panels. It would literally cost us thousands of dollars to buy enough solar panels to run our off grid home. There had to be a better way to equip our home with solar panels we figured.

Most everything that you can buy from someone you can probably make yourself- why not learn how to make solar panels.

It turned out that it wasn't as difficult as we thought it might be. Solar panels are manufactured in high tech facilities with very expensive equipment but most of that technology goes into the making of the individual cells that make up the solar panels.

If we could find a source of small solar cells that were already manufactured at a reasonable price and perhaps some decent instructions we could definitely make our own solar panels.

What did we need?

· Guide book on how to make solar panels

· Inexpensive solar cells

· 1 sheet of plywood

· Copper wire

· Sheets of glass

We first located a book on the subject so that all of the fine details could be accomplished. It cost us under $20, but the very first solar panels that we made more than paid for it. We figured we saved nearly $400 just on the first solar panel we made.

The guide book contained mostly information on how to install solar panels (which was very helpful too) but along with that was detailed instructions on how to make our own solar panels.

There were pictures and step by step instructions which really helped a lot. We located a source of inexpensive solar cells and we were off to the races.

You first start out with a sheet of plywood and arrange the cells in rows along the sheet of plywood.

You can make any reasonable size that you want, but the cells must maintain spacing that are consistent as outlined in the book. It really is not tat difficult, just a bit time consuming to set up.

The next step is to drill holes in the plywood so wires can be drawn threw and all of the cells connected together. After the wires are secured a backer board is placed over the back of the plywood to seal the wires in.

A small framing piece is placed on the outside of the plywood that is higher than the cells and in this way you can seal the cells with glass. After that step the whole affair begins to look very professional.

It looks like a commercial grade solar panel all because you followed the right steps. A little bit of trim will spruce it up nicely.

How much will you save by learning how to make solar panels? We routinely make our own 100 watt solar panels for around $150, with prices always fluctuating depending on the price of solar cells.

Commercial bought new 100 watt solar panels run in the $500 range or more so you can see you will save a lot of money.

Adding Windmill Power To Your Home

By adding a wind turbine to your home, you are providing an alternate source of energy. Creating electricity using windmill power can help you reduce what you pay for utilities. Consider being able to live where power lines just won't go, or having power during a storm. Having a wind turbine would be a real advantage for situations like these. It's good for the environment, too. Future generations may use nothing but windmills to power their homes. And it could have a great effect on the economy.

Wind energy is one of the lowest priced renewable energy technologies available today. Stand alone systems, or off-grid living has its advantages. If you choose to live or build a home in a remote area where power lines are prohibited or not available, a wind turbine can power your home. Another reason consumers purchase small wind turbines for their home is to be energy independent from the local utility companies. As a part of being independent, or just having that alternate energy source available, these machines are built sleek as well as neat looking. Most have low maintenance. Over time a small wind turbine will pay for itself, an investment well worth the price you paid for it.

Wind turbines are good for the environment simply because they rely totally on the wind. That means no air pollutants or toxic gases are released into the atmosphere.

Another one of the nice things about your wind turbine is that if it is producing more electricity than your home is actually using, most times the local utility company will purchase the extra power from you. Depending on how much power you use, and how much your turbine generates, that can be a decent amount of money. Sometimes consumers buy home wind turbines just to be able to run a generator should their power go out. This can provide quite a bit of peace of mind.

Before purchasing a system, it would be a good idea to find out about any restrictions or obstacles when it comes to installing a windmill system. For example, some places restrict the height of any structure in residential areas. There might be prohibitions on some types of structures in certain zoned areas.

Approach buying a vertical turbine system like you would in buying a car or a boat. Look over literature from more than the first company you find. Find out how long the warranty lasts on the windmill you intend to purchase. Understand the basics of a small wind system, and even take a look at combining the alternate energy with energy, and its effects. Or if it is going to be the primary source of your home, calculate the power wattage compared to the power consumption you plan on using.

Some states offer tax credits or rebates to home owners with household wind turbines, which offsets the installation or purchase price of the machine. A consumer can check with the local utility company, the utility commission, or a local energy office to find out about these incentives. Or if they are available at your location.

Companies are more than happy to help you purchase a household wind turbine system specifically designed to meet your needs.

Whether or not to add a windmill to your home is a decision only you can make. However, when weighing the advantages and disadvantages, you might find that these lists aren't the same length. It's an investment that helps the economy and you might not have as much out of pocket cash going to your nearest utility company.

Residential Wind Power

Rеsidential wind power works by having a wind turbine attached to the top of a tall tower so that it can collect kinetic energy and change it into electricity so that it may work with your homes electrical system. Wind turbines will have out put if the wind power is over 7 to 10 miles per hour if not then the power that the house needs is purchased by the utility.

If the wind turbine puts out more electricity than is needed for the houses supply, then the rest of the electricity is sold to the utility. A small wind turbine can lower you bill significantly. To determine if a small wind turbine will save you money in the long run you'll have to think about the amount of electricity that your household would be using and also how much wind speed is around your house as well.

Before buying a wind turbine you should remember that the owner of the wind turbine should have a minimum of an average of 10 miles per hour wind speed and also be paying a minimum of 10 cents per kilowatt hour for electricity. Wind turbines help the environment because they output no pollution and by using a wind turbine you are stopping the pollution that would have occurred from electricity generation by the utility company.

During a wind turbines lifetime they can prevent about 1.2 tonnes in air pollutants. You won't have to change any wiring in your house because wind turbines can fit any homes and normally they supply an 80 to 120 tower with the wind turbine.

A wind turbine's performance improves as the altitude increase however depending on the manufacturer there are several different turbines available. Depending on size and the manufacturer, wind turbines can cost anything from $ 6,000 to $22,000. Most wind turbines do not require regular maintenance and over the long term is a good investment.

Vertical Axis Wind Turbines

People have been harnessing the wind's power for centuries to pump water and perform other mechanical tasks. But it's only been in the last few decades that the expertise for converting the wind's energy into electricity has made the necessary strides to become an alternative source for energy production. Most of this technology has been applied to large scale operations and some smaller units for home use.

For the home owner interested in producing their own electricity, choices have been limited primarily to investing in a horizontal axis wind turbine (HAWT). These units can carry a hefty price including the installation of a large tower, maintenance, plus the regulation in some areas regarding tower height, noise concerns and environmental issues.

For city dwellers with no place to erect a HAWT, wind power has not been an option at all. The vertical axis wind turbine (VAWT) provides a more economical alternative for the small scale user. Some of the most recent designs have overcome the problems of early models such as their inability to self-start in light winds plus issues of noise and vibration levels. Most of the new technology works well in an urban or suburban environment where some wind turbulence is inevitable unless the turbine is sited well above any surrounding buildings.

A HAWT has to physically rotate to face into the wind every time the direction changes, requiring a large tower to place the rotors above all obstructions. The VAWT doesn't require such clearances and can keep producing power in these turbulent areas.

Most vertical axis wind turbines are very silent, emitting only a slight humming sound near the equipment. The turbines turn at a lower speed unlike the larger tower turbines where the blade tips can travel at supersonic speeds becoming a threat to bats and birds traveling thru them. For these reasons they are safe to use in population centers, public spaces, parks, wildlife parks and on buildings. Some of the more adventurous designs have the look of sculpture adding another dimension to your installation.

The VAWT systems have a larger wind speed range and are able to self start in light winds, sometimes 2-3 meters per second, and continue producing electricity at much higher wind levels than the traditional HAWT units.

If you are considering alternative energy sources to lower your utility bills or to minimize your impact on the environment, vertical axis wind turbines offer new technology that can help you achieve your goals.

Energy in the Wind

Wind power has long been a source of renewable energy, as evidenced by the many windmills of centuries past. The flow of air is used to run wind turbines, some of which can produce up to 5 megawatts of power. The most common wind turbines for renewable energy used commercially produce between 1.5 and 3 megawatts. The renewable energy that a wind turbine gives off is derived by the cube of the speed of the wind. As the speed of the wind increases the power that the turbine puts out increases almost exponentially. In places where wind is strong and nearly continual such as at high altitudes and offshore are the best places to locate wind farms.

Wind is the fastest growing source of power through any of the renewable energy resources and technologies. In the past ten years, the maximum capacity of wind power installed the world over went from a 1992 high of 2500 megawatts to a high of 40,000 in 2003 and continued to grow each year after that by another 30 percent. This shows no signs of abating. Due to wind being an intermittent energy resource most wind turbines in the European Union only produce an average of one fourth of the power they are actually capable of. Under favourable wind conditions, however, some reach 35 percent or more. In winter the EU realizes a higher load factor. What this means is that wind as a renewable energy in Europe typically has a capacity for 5 megawatts maximum per turbine but regularly produces 1.7 megawatts.

The long term potential for wind as a reliable renewable energy resource throughout the global is probably about five times what it currently produces and forty times what is currently demanded of it. Large pieces of land that are not now being used for wind turbines could easily do so, especially in high wind areas. The offshore areas, where wind is nearly twice as fast and dependable as that of inshore land masses could be increased substantially as renewable wind energy sources.

The strength of the wind near the surface of the earth varies considerably and scientists cannot assure that the earth would have continuous renewable wind energy there unless it was combined with other sources of energy or stored in some way. Some suggest that 1000 megawatts of the capacity for conventional wind gathering could be counted on to produce 333 megawatts of power that is continuous. This could change as our technology evolves, but most experts suggest using wind in the context of a renewable energy system that has an expansive capacity for reserving the energy. Examples of these would be hydro power, desalination plants, reserve loads and the mitigation of the economic impact of variability of resources.

Not only is wind power a renewable energy, but like other renewable energies it gives off no harmful greenhouse gases while being operated - no methane, no carbon dioxide. The one negative of wind power is that bats and birds get caught up in the turbines and get killed. Wind turbines should, therefore, be built where this impact would be least felt.

Will Wind Energy Be Blown Away?

Wind energy is form of renewable energy. This 'new' source of energy is getting more popular and not without reason. In various parts in the world big wind turbine parks are placed by corporate businesses yielding big quantities of energy that can be sold as environmental friendly or 'green' energy. Wind energy is a big business. Big companies profit from renewable energy but also invest substantially in this new energy source.

As you can mention before wind energy is very environmental friendly. In the search for alternatives for fossil fuels this energy source turned out to be very lucrative. This energy source makes us less dependent on traditional fossil fuels. It is important to lessen the dependence on traditional fuels. There are many reasons why here we will inform you with the most important once. The traditional fuels are predominantly in the hands of countries in troublesome areas. Therefore you are not sure if the amount of crude oil you request will be delivered due to instability in the region. Also the price for these old fuels is increasing and the current reserves are diminishing. But most of all these old energy sources pollute our planet. But as always the beautiful story of wind energy has not only positive sides. Let's look at some of negative points as well.

In the Netherlands a windmill park is located in the north of the country. Although the local people here were in favour of the windmills they changed their minds when the mills were actually placed. The residents were complaining about a constant noise during the night that could be compared to a Boeing taking of. These complaints were not taking serious by the corporate business owners. Therefore the residents decided to research their complaints by the local university. The outcome of the research was that the residents were right and their complaints should be taken seriously. It turned out that the windmills produced more noise in the evening and night than during daytime due to a higher turbulence at night caused by very specific changes in the upper air layers. During the day there is less turbulence and the sounds that are produced by the windmills are diminished by the noise of local traffic and wind blowing through the trees. All specifics can be read in this paper: The Sound of High Winds: The Effect of Atmospheric Stability on Wind Turbine Sound and Microphone Noise by Frits van den Berg.

In Germany wind mills where placed in the North Sea. Although the location for this purpose is very good, the park doesn't seem to produce the calculated amount of energy. The windmills often don't work properly due to malfunction. Whilst the location is good and wind is blowing almost constantly the windmills often just don't work. The mills were not moving at all and therefore not producing electricity. This project turned out to be very disappointing, but the project is still running and it is believed that it will function according to plan in the future.

In the United States in Vermont the local residents were opposed by the planning of a new wind turbine park. The locals felt that the wind towers would ruin their beautiful landscape. It is a landscape that many generations have fought to preserve and the current residents our proud of. It is hard to convince people to share their landscape with large wind towers that disturb these beautiful views. The plans for building the windmills in Vermont are of the table.

Although is it a good and economical of energy, wind energy is taking some real blows. The advantages are clear and the disadvantages are becoming clear as well. When placed in a surrounding where the landscape is cherished by the people who live there, one could argue not to place them because it might ruining the beautiful landscape and spoil the beautiful views. Locals and tourist would find these turbines just plain ugly. Also it should be kept in mind that wind turbines with these sizes can produce a lot of noise during the evening and night. Beside these considerations it has shown that wind energy is not always a big success and there is more progress to be made. Technically there are some steps to be made, but a lot of people are working hard in this. Let's hope that wind energy is here to stay and we will find proper ways to utilise this form a way that we all can benefit from it.

Lower Your Utility Bill

Are you concerned about your home energy bill? Has it increased the past years to numbers you could not even have imagined back than? Do you feel like it is time to turn this around and start paying less? Of course you do! You don't have to throw out all your appliances and devices, nor will you have to live like a night creature in the dark. What you can do is to invest in one or more home energy generation systems.

A home energy generation system can be the solution if you were eagerly searching for a way to lower those bills. Such a system provides you with the best way to get the maximum financial freedom on home energy. It will give you the opportunity to utilize alternative energy. However this will mean that you will have to invest in these systems, because they don't come cheap. But it will be worth every penny you have spent! Among all types of alternative energy that can be used, wind energy and solar energy are the most common. Let's review them briefly here.

Let's start with wind energy. Wind energy is becoming more and more popular and for good reasons. Wind energy is accessible for many households and is very abundant in many parts of the country. Thus, many household can capitalize on the use of wind as a source of home energy. On the downside wind varies vary on a daily basis. Thus, it may be blowing strong today but tomorrow can be different. And even on the breeziest places, you can never tell when will be the next strong wind blow occurs. Even though this is true is, it also a known fact that wind pattern exist. Summers will bring less wind than winter, then the winds are strong and will keep your turbine spin most of the days.

If you are really interested in wind turbines it is note worthy to make sure that the local zoning allows wind turbine. You must also ensure that there is a good source of wind on most days. A wide and open space, at least 1 acre, would be ideal for wind turbines. And, if you are paying more than $150 monthly, then it may be a good option for you. If you are living in the suburbs than the 1 acre space can be big problem. Although there are new and improved smaller wind turbines available, you would still have to get permission to install the turbine. That's were the next alternative energy source comes in.

The next source that is widely used all over the world is solar energy.

Solar panels can be placed on your roof. It can be argued if the solar panels ruin the view of the homes in the neighbourhood. It is purely a matter of taste. But it is not likely that you would not get permission to place them on your roof. The early panels used to reflect a lot of sunshine and could block vision. Just like a mirror reflecting sunlight and could be blinding the eyes. But that was long ago. Today's solar panels don't have that mirroring effect anymore and the efficiency has been improved also. When they first were produced the efficiency was around 5 %, today the efficiency has tripled to 15%.

The modern panels are lightweight, safe and most of all, easy to install. These are essential in order to place them above your roof.

Your roof is also susceptible in UV exposure. The solar panel eliminates this. Also your roof will be protected from weather.

Another benefit is that solar panels contribute in keeping your house well insulated. They provide extra covering and enable you to save as much as 30% on heating expenses.

Drilling holes in your roof is very risky. The interlocking solar panels eliminate this risk.

Solar panels come in different sizes. This means that you can buy a solar panel no matter what the size and shape of your roof is.

Solar panels are installed without requiring you to modify your roof. It will adapt instantly.

Solar panels can be used on every home with a roof. That means that you don't have to live in the country to profit from this energy source.

And you don't even need a full day of sunshine to profit from this energy source. It doesn't matter if it is cloudy or raining day, these panels work on light. The generated power will be less than on a sunshiny day, but it will generate energy.

You can use these panels for electricity and hot water. The hot water can be used for central heating and running hot water. The electricity can be used for your appliances.

Solar power and wind energy can reduce your utility bill tremendously. A combination of both would be the best solution. Although these systems are expensive it would be worth every penny. If you are really serious about alternative energy sources than don't forget the tax credits and other benefits for installing these devices.

Micro Wind Turbines For Cities

When discussions of renewable energy are undertaken, the focus is often on large scale projects. In truth, the answer may be platforms developed for a more local application.

When renewable energy is discussed, most people picture large structures. With solar, it is a valley full of solar panels glittering in the sun. With wind power, most think of large turbines gracefully twirling in the wind as they sit in valleys or up on hills. As more money is put into renewable energy research, the research results are producing an entirely new spectrum of devices.

With wind power, one of the issues is finding optimal places for placing turbines. Monetarily, this can be problematic. The best wind locations are often located smack dab in the middle of developed areas. Even for areas that are available, the cost of setting up transmission lines for the resulting energy can be obscene. Given this catch-22 situation, many have started working outside the box on wind power platforms.

Oregon State University and AeroVironment, Inc, have come up with a unique solution for the wind power problem. Their idea is to abandon the wind farm idea completely. Instead, they are looking to applications that can be used on a per structure basis. In this case, the solution is micro wind turbines.

Micro wind turbines are essentially wind turbines on a scale of a couple of feet in height instead of thirty or forty feet. The idea is to place the turbines on the roofs of buildings to capture the wind that is often found rushing over the edge of roofs. The turbines are designed to be modular, meaning they can be added to the roof on an as needed basis. This is accomplished by using a track system similar to lighting in a home as the base for the turbines. Depending on the energy needs of the structure, one, ten or 100 turbines can be installed.

Admittedly, a row of little wind turbines may look a bit odd on your average office building. On industrial buildings and warehouses, however, the structures would make little or no difference to the appearance. Heck, they would probably be an improvement. More importantly, the turbines would represent energy independence for many of the businesses using the buildings. Unlike solar, the turbines would generate power during both the day and night, meaning power could be stored in batteries or the utility grid at night to cover high energy use periods during the day.

Micro wind turbines may or may not become part of the solution to the energy issues before us. What is clear, however, is talented people are starting to focus on the subject and come up with innovative solutions.

Wind Farm Efficiency

Wind power is an incredibly clean renewable power source. To capture the energy in wind, wind farms are used. So, how about wind farm efficiency?

Wind Farm Efficiency

Wind power is the process by which wind is used to generate power or electricity. The power of the wind is actually a form of solar power – wind change and variability is caused by uneven heating of the ground by the sun. In order to fully use the power that the wind is capable of generating, many countries have set up wind farms. In a wind farm, many different wind turbines (a structure that uses a propeller-like blade to take in the wind's power) are set up in an area. With all the wind turbines working at the same time, it's thought that these farms are a great way to produce large amounts of electricity.

To determine the efficiency of wind farms, you need to know how a wind farm works. The wind turbines collect the power of the wind in two steps: the propeller blades are turned by the gusts of wind, and the propeller then turns a shaft. This turning shaft is connected to a generator. The spinning action cranks the generator, which then produces electricity. The process is exactly like hydropower, but with wind acting as the energy source instead of flowing water. Just one wind turbine set up in an area will not produce very much electricity, and is not very good for powering large areas - these small turbines are usually used to power just one farm or house or occasionally to pump water.

Wind farms, on the other hand, are more powerful because there is a large grouping of the wind turbines in one area, all working in unison to produce electricity. The energy can then be run to whole communities through existing utility grids or stored in battery-like storage cells. Wind turbines can be set up to face the wind or face away from the wind. Modern wind turbines can also turn to catch the wind as it gusts from different angles, a factor which makes them far more efficient than before. The larger the turbine's blades and the taller the turbine's height will increase the efficiency as well.

The exact efficiency of wind farms is nearly impossible to pinpoint. The problem is found in the factors that go into the analysis. The terrain, amount of wind, size of turbines and so on varies from wind farm to farm. There is no constant, which makes it difficult to nail down general efficiency ratings. In general, a single wind turbine will convert about 20 percent of the energy in wind to electricity. The most efficient production occurs between five and 20 miles an hour of wind speed. This general 20 percent efficiency rating is roughly seven to five percent more efficient than solar power, but sunlight is constant whereas wind is not.

While wind technology has not yet progressed to a point where no energy is lost while harnessing it, it is fair to say that the platform is favorable compared to other renewable sources. It may take a while for the whole world to catch on to using the power of the wind, but it's definitely fast becoming an important alternative energy source. Countries such as Germany are certainly investing a lot into the platform.

Wind Energy – Germany

When many people think of German, they think of a large oil based industrial nation. In truth, Germany is a leader in wind energy. Here is a guide to wind energy in Germany.

When looking at countries that use wind energy, Germany tops them all. The world's largest wind energy producing country, Germany has pioneered the use of wind to produce much of their electricity needs. While the countryside and area of Germany that can be used for wind energy production may seem small compared to the size of some other countries, such as the United States and Canada, Germany has managed to make the most of the area they have, incorporating wind farms into their rural areas as well as in off-shore locations.

With wind energy, Germany is able to produce 3.5 percent of their electricity needs for the country. While this may not seem like much, compared to other countries that only produce a fraction of a percent of their electricity with wind – Germany is definitely on the right track. The country also predicts that they will be producing more and more electricity through wind energy in the years to come. For instance, in the year 2001, Germany accounted for half of the world's production of wind turbines.

Germany is also being heralded as a forefather of the wind energy revolution, because of their plan to add 5,000 wind turbines to a wind farm located off the north coast of the country. Some of the wind turbines would be located up to 45 miles out at sea, a feat never before tried by a wind energy consuming country. The wind at sea is more powerful as well, therefore Germany sees the potential to produce even more electricity by using off-shore wind farms.

The turbines being developed for use in this sea-based wind farm are much larger than conventional wind turbines, so that they will be able to fully use the wind energy that is found in the water. Germany expanded their wind powered electricity production by 44% in the time between 2001-2002, with more and more turbines being added constantly. Germany already has about 11,000 wind turbines in use. The cost of wind electricity can be as low as $.03 per KW hour, which is less than half that of the next cheapest electricity producing energy source.

While it's first in wind energy, Germany has no plans to stop there. The country plans to continue expanding their wind farms and use of renewable energy sources, which will both benefit the environment and cost less for the consumer. Other countries in Europe are starting to take notice as well, with estimates that over 50 million consumers could be receiving wind powered electricity in the next 10 years.
