Wind Power Benefits and Drawbacks

Sunday, November 22nd, 2009

Over the past ten years, residential wind turbines have improved significantly, so much so that they’re now a realistic, serious option for a growing number of homeowners. The new designs of today generate more power from less wind than ever before, thanks in part to advanced materials and technological achievements. The sheer variety of sizes and styles of residential wind turbines now available means that interested homeowners are certain to find a unit to meet their needs.

Benefits

Endless energy

We’ll never run out of wind (though the same can’t be said about some other sources of energy). The wind will keep on giving us energy – as long as we take the steps to harness it – permanently. Fossil fuels can’t make that claim. Oil and natural gas supplies are not permanent. Once they’ve run out, there won’t be any choice but to switch to other sources of energy. Decreasing supplies mean rising costs, and the unlimited nature of wind means that its price stays constant, and therefore more and more attractive by comparison.

Free power

If you’re using wind energy, you won’t have to worry about kilowatt hours or anything like that. Wind power is free in perpetuity once you’ve installed a wind generator. It really is possible to go “off the grid” and provide all of your own power with a residential wind turbine, never having to pay an electric bill again.

No emissions

Wind power is totally free of pollution. Fossil fuels, on the other hand, produce all kinds of pollution. You can reduce your carbon footprint significantly by using wind energy instead.

Forget about foreign oil

Dependence on foreign oil is an important issue that affects us not just as individuals, but as a nation. One of the best ways to reduce dependence on foreign oil to switch to wind power, as this will eliminate the need for oil of any origin.

Energy at all times

One of the advantages that wind power has over solar power is that it can generate electricity for the home at any time and in any weather. Solar panels can’t be used as a complete power solution, as they only produce electricity when the sun is shining. On overcast days, or at night, you’ll need an additional energy source, such as power stored in batteries or bought from the power company. Wind energy, on the other hand, isn’t subject to these limitations.

No home orientation problems

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 too much shade, or not enough southern exposure on the roof, this can be a problem. A wind turbine will produce power regardless of any of these factors. Wind generators are also more efficient in terms of use of space than solar panels are.

Drawbacks

Installation cost

Even though the ongoing costs of wind power are negligible, some people are intimidated by the costs associated with getting started. Before long, though, the free electricity that comes from a wind generator will more than offset the installation cost. If you’ve got the know-how, some basic tools, and some free time, you can even put together your own wind generator, which will make the whole process even more sensible from a financial standpoint.

Height requirement

In order to get enough wind to generate their full potential in terms of power, larger wind turbines [needhave] to be mounted at a certain height. This often means that it’s necessary to raise the turbine up above any nearby buildings and trees. This means that, a lot of the time, users mount wind generators on top of towers or other tall structures. The HOA permits or approvals that are sometimes necessary in order to carry this out can add to the up-front cost of starting up a wind generator. But, once again, constructing home made wind turbine will help lower the cost.

Consistent wind needed

Consistent wind is a must in order to produce a really useful amount of power from a wind turbine. Very windy areas are the best for this purpose. Areas with relatively few buildings or trees are the best in this regard. While it is possible to produce significant wind power in wooded or urban areas by mounting the wind generator on a tall structure, it is certainly still better and more cost-effective to generate wind energy in areas that don’t have these features. A DIY guide will teach you how to build a wind generator.

The above are the main characteristics that make wind power unique. For most people, the disadvantages seem pretty insignificant in comparison to the advantages. Even in terms of renewable energy sources, wind power has its own distinct selling points. The specific disadvantages of solar are, in some ways, the strengths of wind power. Solar and wind power do share the common disadvantage of being expensive to install. However, this cost can be greatly reduced by putting together your own wind generator.

Facts About Wind Power

Thursday, October 15th, 2009

It is possible to create high levels of power with the kinetic energy of the wind.  All the energy that is gotten from the wind is referred to as “Wind Power”. The following are some wind power facts that will provide valuable insight into the adoption of this method. The creation of electrical power that is done today is achieved through wind turbines or wind generators. These three types of instruments represent the most common wind power system.

Take a look at another fantastic article about wind power. see: How To Design Wind Power

The principles behind a wind system are fairly simple. The wind turns the turbine blades by virtue of its motion and this in turn produces. With a rotor between, the blades are linked to the main shaft. The action of the shaft spinning causes the generator to create energy.

The body of the tower houses the mounting of the windshaft. With increased heights, better wind conditions can be found. Therefore, in order to guarantee the best the energy input, turbines usually need to be fixed at a minimum of a couple of feet from the ground. For the best results, it is advised that you install your turbine on a tower that is at least a 100 feet.

Additional Wind Power Facts

When people consider the use of wind power, the main fact that comes to mind is that winds can effectively generate green energy. A generator is used for the transformation of wind energy into electrical energy. Once installed, wind generators produce electricity entirely free of charge.

Wind energy has long been harnessed. For instance it was used actively used by sailing ships at sea. Wind energy can also be turned into mechanical energy which is then used in the grinding of grain or water pumping . The generation of power, is however widely considered the most popular use of wind energy.

Huge wind turbines are often regrouped on wind farms to feed power into the electrical grids. In rural areas, smaller turbines are used to generate electrical power for off-grid properties and remote cabins. Householders are increasingly starting to produce power in order to accommodate their own needs. In most Western countries nowadays, utility providers are even willing to buy all surplus electrical energy which is produced by the household’s wind generators.

Yet another benefit of working with wind energy is the fact that its use can be finely spread. Proving different from most power options, it carries no emission threat and does not contribute to the pollution of the planet.

With regular maintenance, wind turbines can last forever thanks to an unlimited supply of wind energy. Due to all of these positive qualities, wind power has become well loved among nature conservationist, as they acknowledge that it does not cause any negative impacts to the environment.

The best part is that almost anyone can start benefiting from this rich energy, by harvesting it at home, through the means of a custom wind turbine. The DIY (do it yourself) approach is fantastic because it makes the technology available to everyone, even beginners. With the help of a proper kit or instructions guide, we can all easily construct fully functional windmills.

In the recent years, some countries such as Spain, Denmark and the U.S have increased their wind energy production tremendously. A total of 120.8 Gigawatts of energy was produced with the help of wind power in 2008. This has resulted in an increase of as much as 45% of annual energy production in the United states.

In the recent years the technology and constucton of wind turbines, used in the generation of electrical energy, has increased in development exponentially. This has resulted in causing wind turbines to be even more productive than they originally were. The facts about wind power show that this technology is by far the least expensive source of renewable power available and that the future only reserves room to grow in terms of possibilities.

I really hope you have enjoyed reading this article, its time to check out : How To Use Windmills For Electricity. Here you will discover a great ebook with step-by-step instructions and video lessons to help construct and complete your very own turbine which you can use to start generating power of your own straight away.

 

Recent Advancements in Home Wind Turbines

Thursday, October 1st, 2009

For decades now, wind turbine technology has been getting better and better. The great improvements in the past decade have allowed it to be increasingly used for residential production of electricity Modern wind turbines can be a very good source of alternative electricity for many consumers as they are quieter, smaller and produce more energy than ever. Homeowners can now find guides and plans that teach how to build a wind turbine.

Size and the requirement of a consistent, very strong wind were the most significant problems with early types of wind generators. Early types of windturbines required very strong and consistent wind to get them turning. Because of their size and height requirements, they were not a good fit for many homeowners even though they produced considerable amounts of electricity. Because these wind turbines were being used in residential environments, they needed to be mounted very high in the air to catch a consistent wind. They had to be higher than other buildings and trees so that they would be exposed to as strong of a wind as possible to allow them to generate their maximum power. In order to accomplish this, the wind turbine had to be mounted at the top of a heavy duty, and often ugly, tower which was expensive and could cause complaints from neighbors. Many HOA rules or town ordinances also prohibit or restrict towers or wind turbines. Large, open areas, free from tall buildings and trees were a better fit for these old, large units.

Modern wind turbine designs have reduced the size of the generator and helped homeowners with smaller lots or in areas with trees or buildings. The smaller, newer wind generators need much less wind to turn. Because of innovative construction materials, more modern wind generators are also much lighter than older models. This means that they don’t need to be mounted as high as the older wind turbines and can still produce a good amount of power from a smaller wind. Another improvement in these more recent wind generators is their blade design which allows them to be more efficient with the wind they receive and quieter as well. These newer wind generators are also much quieter and more efficient thanks to their blade design. People who live in smaller neighborhoods can generate renewable energy without disturbing their neighbors with these newer wind turbines.

The newer wind generators can turn more quickly and produce electricity sooner than the bigger ones because they are much lighter. A wind turbine has to be pointed into the wind for it to produce electricity. This is usually accomplished through the use of a tail rudder. With the larger wind generators it took a strong wind to orient them before they could start spinning to generate power. Many times they might not even produce power at all because they can’t spin up in a light wind. Because of the much lower wind requirement for spinning up, the newer, lighter wind turbines can spin up and start generating energy more quickly. The result is that the older and heavier wind generators might have been able to produce more energy when they were spinning, but they were spinning less often. Over the course of a year, the newer, smaller wind turbines can generator almost as much energy as the larger, heavier ones because they spin more consistently. Many of the more recent wind turbines can be mounted directly to a roof and significantly reduce installation costs because of their much smaller size. A homemade wind turbine is a perfect alternative for any homeowner looking to generate some free energy from a passing breeze.
