Solar wind energy is energy that is produced by the wind.The horizontal axis turbines and the vertical axis turbines are two of the most frequently used windmills that are used to produce solar wind energy but there are other types also, and it all depends on where they are located and how much power they are meant to produce.Typically in order to harness the power of the wind, a windmill is used although there are other devices that can replace this.Solar wind energy has a lot of benefits to offer, and people have been taking advantage of these benefits for years now.

One of the greatest benefits offered by solar wind energy is that it can be used in place of electricity.It is cost effective for one thing which is an advantage that all people can appreciate, especially today when the economy is so poor.There are also wind turbines which can be used to harness the energy of the wind and create solar wind energy, and these are available in an array of sizes and are very similar to the windmills but with a few major differences.You will see that your electricity bills will be cut in half and you are going to be really glad that you made the switch.

Solar wind energy has been relied on for years now, but only now is there really all this fuss about it.There are certain downfalls to solar wind energy as well but these are few and in between.One is that solar wind energy can still be outside of the price range of some people even though it will end up paying itself off.This is because you will have to spend the money to get enough supplies to power your whole home and if you live in a larger home this could mean that you will end up spending thousands of dollars to get enough solar panels and other supplies.

However it has been found that energy efficiency can be found in wind energy. It is more efficient than coal generated power plants. This means that you could actually get more energy from a wind farm than from a conventional power plant.

The Great Things About Wind

There are plenty of great things about alternative wind energy. Chief among those things is the fact that it is completely free. You can count on wind to always be there unlike coal or gas that is not renewable. Many people consider green energy to be economically inefficient. It is often considered too much bother and expense to go to. However this is not true at all, in fact it can be even cheaper than conventional electricity.

In fact alternative wind energy is very low cost. It is quickly becoming one of the cheapest forms of electricity. It is also a completely safe way to generate electricity, it does not have the risks of nuclear power plants. The only problem is that when there is no wind the wind turbines are not able to generate wind.

For this reason most places are not able to operate solely on wind turbines alone. If you would like to use alternative wind energy in your home you will most likely have to use power from the main grid alongside a wind operated generator.

However you can cut down on the dependence of using electricity from the main line. The good news is that by using alternative wind energy you can not only stop polluting the atmosphere by using a safe and clean energy source but you can also offset carbon emissions from your local power plant.

Continuing to use alternative wind energy over a period of years will help to offset tons of carbon emissions. You will be making a big contribution to the environment and saving yourself money over a long period of time. If these things are attractive to your then alternative wind energy is a great idea for you and your home.

It may also be a practical solution to supplying wind turbine energy to your home if you live in a remote area. In remote areas it is often difficult to supply a home with enough electricity or it may be very expensive.

Where Can I Install A Turbine?

A primary concern when deciding to install a wind turbine energy system is whether your home is physically suitable for installing one. The first specification is the wind speeds that occur in your area. If they are below 10 mph then the wind speeds are not high enough for a wind turbine energy system to work properly.

A wind turbine energy system works best the higher up it is. Typically an alternative wind energy system will work best when installed on top of a hill that is free from obstructions such as houses, trees, and other large building. A hill with a flat top is ideal. A reason for high wind turbines is that wind speeds are faster the higher a wind turbine energy system is.

For this reason if you live in an urban area a wind turbine energy system is not the best way to generate power for your electricity needs. However if you would still like to use a wind turbine energy system to generate electricity then you would be best served by a micro wind turbine.

This kind of wind turbine can be mounted to the roof of a building or on a mast that is near the building that needs to be powered by electricity. One drawback is that most turbines will generate direct current electricity. You may need a converter to change the current to an alternating current.

The cost of a wind turbine may seem very high but if you live in the right area you may be able to reduce your electricity bill so that you are paying 90% less than you would normally pay. The attraction to using this kind of generator is that it will last you for as long as 30 years. Even if the initial cost is very high it is a long term investment.

Residential Wind Turbines

When employing a wind energy system to supply electricity a home will most likely rely on wind turbines and the utility company. When wind speeds are low the wind energy system will not generate enough electricity and electricity will be supplied by the utility company.

The higher the wind speeds the more electricity will be generated by the wind turbine energy generators. Sometimes the wind turbines will generate more electricity than the house needs, in such a case the excess electricity is sold to the utility company. This is done automatically.

Is My Home Suitable?

In an urban setting using a wind energy system is not suitable as there is usually not enough land. The best kind of home will have at least an acre of land around it. The wind conditions around your home will also influence whether a wind energy system will benefit you. Winds need to be higher than 10 mph for there to be significant output from the wind turbines.

If your home is suitable for a wind energy system then you can expect to see lower electricity bills. You can reduce your home energy bill by as much as 90% if your area has the right wind conditions. Although this does mean you can expect to see a lower electricity bill, you will have had to pay for a wind turbine first.

How Does It Help?

Although you will have to pay for the initial cost of the wind turbine it will be paid back in subsequent years with lower electricity bills. A wind turbine will also last you for 20 to 30 years. You can also make your contribution to the environment by using this clean energy source.

Not only will you be generating clean energy but you will also be offsetting pollutants that your utility company releases. If you live in a suitable area then using a wind energy system might not only benefit the environment but can also save you money in the long term.

Great Energy

Creating sustainable energy has long been a challenge when the answer has been sitting in front of us for centuries. Wind power has been used by humans for many centuries in agriculture, in Babylon, China, and if you think of windmills you will understand that wind power is not a new technology.

One of the advantages of wind energy is that it is a renewable source. In an area that receives high levels of wind this is the perfect energy source. It can never run out and best of all, and perhaps high on the list of the advantages of wind energy, is that it is a totally free source of energy. There is no need to pay a foreign country for it or to pay more for it when it becomes scarce.

Another one of the great advantages of wind energy is that it does not pollute at all. It is one of the rare ways to generate electricity that does not give out greenhouse gases or destroy the environment. Any energy used in the installation can be gained once the wind turbines are in use in a period of three to six months.

A wind energy system is also a low cost way to provide electricity. It could soon be the cheapest way to generate electricity. The main cost of generating electricity in this way lies in the installation of wind turbines. Though the cost may rise if the land that the wind turbines are built on is expensive.

The Disadvantages

While there are many advantages of wind energy there are disadvantages associated with using wind energy. One of the disadvantages of wind energy is that although it does not pollute it does cause noise disturbances.

Though this is negated by the fact that not many wind farms are built near residential areas and newer models of wind turbines are usually designed in such a way that noise disturbances are decreased significantly. Wind energy is also not transmittable, the area that it supplies energy to must be nearby.

The true cost of wind energy reveals that it is a cost effective way to provide electricity. Many of the costs are paid once and then it does not need anymore financial input. From this point of view it is an economical way to supply electricity especially in remote areas and in a time of rising oil and gas prices.

Capital Costs

The capital cost of wind energy are the main costs and once they are paid off there are no more costs. Most of the money that goes into setting up a wind farm is focused on the wind turbines. The cost of wind energy has come down in recent years, this is good because more turbines can be put up for less money thus generating more electricity.

The rest of the costs associated with a wind farm have to do with the installation process. Roads, cables, and legal fees are all other costs associated with wind energy. The cost of building a wind farm varies depending on the geography of the area and other factors that are site specific. The number of wind turbines also determines the cost of wind energy. Though in general terms a larger wind farm is cheaper than a small one.

Maintenance

Maintaining a site can also be expensive. Though if you compare it with other kinds of energy generators there are lower maintenance costs when it comes to wind energy. Wind energy also needs less supervision than for example a nuclear power plant.

This means that it is a cheaper form of energy. The low cost of wind energy is associated with wind farms as servicing and maintaining a single wind turbine is more expensive than maintaining several in one site.

The cost of wind energy has come down enough that you are likely to pay as much for your electricity as you would for conventionally generated electricity. This means that is now a very affordable source of energy.

Though this is not always true and costs of wind energy can be expensive depending on the area and factors such as proximity to wind farms and who is supplying the electricity.

In fact many people forget that the concept of using wind turbines is not a new one. Windmills have been around for a long time and people have benefited from using wind energy for many years before it became an eco friendly way to generate electricity.

Suitable Areas

Not all areas and locales are suitable for harnessing wind power energy. To have a successful wind farm as areas with wind turbines are called, a steady and reliable source of wind is needed. Not all areas benefit from windy conditions. For this reason a wind farm is best built in a coastal area, on rounded hills, in mountainous areas, and open plains.

The concept of wind power energy is very simple and the way it works is even more simple. The wind turbines usually have propellers that are turned by heated air that blows in the area. The action of the turning propellers generated electricity in a generator. It is a similar concept to a dynamo but on a much larger scale.

Excellent Energy

The areas around a wind farm does not have to go to waste. The earth can still be used for farming so farmland does not have to be abandoned to build a wind farm. It is also a completely green energy that does not give out greenhouse gases. Wind power energy is also a very cost effective way to supply electricity especially as it does not rely any fuel at all.

It is the perfect way to supply energy to remote areas that might not have easy access to a power grid. In fact many farms already have their own mini wind farms to provide electricity. There are downsides to using wind power energy, as there are to using any kind of energy source.

Nearby homes can often suffer from disrupted television service. If you happen to live near a wind farm built with older wind turbines then there is a chance that it will be very noisy. Newer wind turbines however have minimized this problem. The advantages of using wind power energy seem to outnumber the downsides.

The costs it seems are too high and although it is a very green energy it doesn't seem viable. Although wind energy was expensive in its infancy it has now becomes more accessible and is being seen as a good way to provide electricity without polluting the environment.

Fighting Climate Change

In recent times renewable source of energy have become increasingly important as old sources of energy diminish and do more damage to the planet. If we are serious about fighting climate change then wind energy is one of the ways we can make progress on this front.

It is a totally clean energy that has no negative side effects on the environment. Wind turbines are built to last a long time and a wind turbine will typically last for 30 years once erected. When you take down a wind turbine you will find that there is no damage to its surroundings. In this way wind energy is a totally clean way of creating electricity.

Competitive Pricing

Switching to wind energy doesn't have to be expensive anymore. It was once a very costly source of electricity. This has changed and wind turbines are nowhere as expensive as they once were to construct. You can now be sure to have electricity that costs as much as conventional electricity. The competitive pricing of wind energy makes it even more attractive, besides being good for the environment it is cheap!

Is It Reliable?

Wind energy relies on wind, so how reliable is wind energy? The answer is that it is very reliable. While wind may not be constant wind energy technology is reliable and can capture up to 90% of the available wind energy. It might be surprising to know that conventional energy stations are not able to convert all the available energy into electricity and actually suffer far more energy loss than wind powered electricity facilities.

There is no longer any reason to object to wind energy. It is a safe, reliable, and cost effective way of generating electricity. Best of all it's good for the environment and when something can do the job of an old technology why resist change? Unlike nuclear power, there are no threats to the safety of communities around a wind energy facility.

The main renewable energy resources that you know about are sunlight (solar energy) and wind energy and perhaps to a lesser extent tidal energy systems and geothermal energy systems. All of these are in some way or another connected to the sun, which is the ultimate life giver on this planet.

The Earth-Atmosphere system is in equilibrium such that heat radiation into space is equal to incoming solar radiation, the resulting level of energy within the Earth-Atmosphere system can roughly be described as the Earth's "climate." The hydrosphere (water) absorbs a major fraction of the incoming radiation. Most radiation is absorbed at low latitudes around the equator, but this energy is dissipated around the globe in the form of winds and ocean currents. Wave motion may play a role in the process of transferring mechanical energy between the atmosphere and the ocean through wind stress. Solar energy is also responsible for the distribution of precipitation which is tapped by hydroelectric projects, and for the growth of plants used to create biofuels.

The IEA explains it like this:  "Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources."

* Let's first examine wind power as a source of green alternative energy.

A wind turbine needs air, lots of it. A modern wind turbine ranges from 600 KW to 5 MW of rated power, although for commercial use the output range is typically 1.5-3 MW.

Since wind speed is not constant, a wind farm's annual energy production is never as much as the sum of the generator nameplate ratings multiplied by the total hours in a year. The ratio of actual productivity in a year to this theoretical maximum is called the capacity factor. Typical capacity factors are 20-40%, with values at the upper end of the range in particularly favourable sites. For example, a 1 megawatt turbine with a capacity factor of 35% will not produce 8,760 megawatt-hours in a year, but only 0.35x24x365 = 3,066 MWh, averaging to 0.35 MW. Online data is available for some locations and the capacity factor can be calculated from the yearly output.

Globally, the long-term technical potential of wind energy is believed to be five times total current global energy production, or 40 times current electricity demand. This could require large amounts of land to be used for wind turbines, particularly in areas of higher wind resources. Offshore resources experience mean wind speeds of ~90% greater than that of land, so offshore resources could contribute substantially more energy. This number could also increase with higher altitude ground-based or airborne wind turbines.

Wind power is renewable and produces no greenhouse gases during operation, such as carbon dioxide and methane.

Wind Power Market

At the end of 2008, worldwide wind farm capacity was 120,791 megawatts (MW), representing an increase of 28.8 percent during the year, and wind power produced some 1.3% of global electricity consumption. Wind power accounts for approximately 19% of electricity use in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland. The United States is an important growth area and installed U.S. wind power capacity reached 25,170 MW at the end of 2008.

Horse Hollow Wind Energy Center, in Texas, is the world's largest wind farm at 735.5 MW capacity. It consists of 291 GE Energy 1.5 MW wind turbines and 130 Siemens 2.3 MW wind turbines. A proposed 4,000 MW facility, called the Pampa Wind Project, is to be located near Pampa, Texas.

In the UK, a licence to build the world's largest offshore windfarm, in the Thames estuary, has been granted. The London Array Windfarm, 20 km off Kent and Essex, should eventually consist of 341 turbines, occupying an area of 230 km². This is a £1.5 billion, 1,000 megawatt project, which will power one-third of London homes. The windfarm will produce an amount of energy that, if generated by conventional means, would result in 1.9 million tonnes of carbon dioxide emissions every year. It could also make up to 10% of the Government's 2010 renewables target.

Wind Farms

Wind power is one of the most environmentally friendly sources of renewable energy

A wind farm, when installed on agricultural land, has one of the lowest environmental impacts of all energy sources:

* It occupies less land area per kilowatt-hour (kWh) of electricity generated than any other energy conversion system, apart from   rooftop solar energy, and is compatible with grazing and crops.
* It generates the energy used in its construction in just 3 months of operation, yet its operational lifetime is 20–25 years.
* Greenhouse gas emissions and air pollution produced by its construction are low and declining. There are no emissions or pollution produced by its operation.
* In substituting for base-load coal power, wind power produces a net decrease in greenhouse gas emissions and air pollution, and a net increase in biodiversity.
* Modern wind turbines are almost silent and rotate so slowly (in terms of revolutions per minute) that they are rarely a hazard to birds.

Studies of birds and offshore wind farms in Europe have found that there are very few bird collisions. Several offshore wind sites in Europe have been in areas heavily used by seabirds. Improvements in wind turbine design, including a much slower rate of rotation of the blades and a smooth tower base instead of perchable lattice towers, have helped reduce bird mortality at wind farms around the world. However older smaller wind turbines may be hazardous to flying birds. Birds are severely impacted by fossil fuel energy; examples include birds dying from exposure to oil spills, habitat loss from acid rain and mountaintop removal coal mining, and mercury poisoning.
