Since about 1790 windmills were also used in Europe especially in Denmark to generate electricity. At the time those wind turbines already provided 25% of the energy needed by the Danish industry.

Back in those days rich and entrepreneurial people asked the same questions as you and I ask today with regards to how to build a windmill or build wind turbine respectively.

The availability of cheap and readily available oil destroyed the windmill industry in the past.

Today our current energy crisis has led people to see wind power as a valuable natural energy resource. By using wind power we can cut down on our use of fossil fuels and reduce the harmful gas emissions into our environment.

All we need to harness this clean and renewable energy are some wind turbines.

So, how can you build wind turbine by yourself?

Well, the process is pretty simple.

Before you can start to build your own wind turbine it is important that you understand the technology behind the system.

A wind turbine has a number of blades that are attached to the shaft of an electricity generator. When the wind spins the blades around the generator produces electricity. The system is very simple but very effective.

With this knowledge in mind let’s find out how to build wind turbine.

The first thing you need is the motor for the wind turbine. You can either buy one or if you have some knowledge of electronics you can probably make one yourself.

Most of what you need to make a motor you can find at any scrap metal yard.

Once you have the motor you should also invest in some good oil as the motor in your wind turbine needs to be oiled regularly.

When you have the motor and scrap metal for the blades you can start to build wind turbine. However, if you want to carve bigger blades for your wind turbine you need to have a large enough workshop.

Many people find it easier to start learning how to build wind turbine by using special diy kits.

Over the past year or so a number of different wind turbine making kits have been developed and patented. These kits are especially helpful for people who cannot get all the materials together.

Many people choose this option to make their wind turbine. It is more convenient, you spend less time searching for the materials to make the wind turbine and you might even get a better result.

If you prefer to build your own wind turbine completely from scratch instead of using a kit, we recommend that you buy an instructional manual or book from your book store or online that shows you exactly step by step how to build wind turbine.

These guides are very helpful as they also give you instructions on making different sized wind turbines. You can find out exactly what dimensions the materials have to be to make exactly the type of wind turbine that you want.

Once you have learnt how to make wind turbines and if you enjoy the process you might even set up your own how to build wind turbine business.

Wind energy is quickly becoming a very popular way to generate electricity and more and more people will want to build their own wind turbine.

If you want to take advantage of this growing industry you should do so before everyone else gets the same idea. Your financial rewards might be plentiful.

Wind Energy Advantages

Unlike energy that is generated by burning fossil fuels such as coal and oil, wind energy does not generate any green house gas emissions. This is one of the main wind energy advantages.

Wind and solar power are often considered to be some of the best sources of natural energy. As a matter of fact, wind power is actually a derivative of solar energy.

The heat from the sun causes changes in weather patterns which in turn lead to the creation of wind.

There are a number of wind energy advantages but one of the main advantages that is always mentioned whenever you hear about wind energy is the fact that wind is a vast, freely available and renewable resource.

Wind energy is continually replenished i.e. there is always new wind being created. Unlike fossil fuels we cannot run out of wind.

Because of its’ low running costs many people choose wind power over other forms of electricity.

Like other renewable forms of energy the biggest cost involved with wind energy is the initial cost of setting up the wind system.

Of course, there will also be some maintenance costs involved, but these are very similar to the maintenance costs involved with traditional electricity generation. Wind turbines need to be checked and oiled regularly so that the wind power continues to work effectively.

Out of all the wind energy advantages the next one is probably the advantage that has been most discussed in the media.

While the continual burning of fossil fuels causes big problems to the environment, wind energy itself does not cause any pollution such as smog, acid rain or global warming. It is especially the global warming that is of the biggest concern.

Scientists and Climatologists have indicated that global warming could be the reason why the seasons and other weather patterns are changing so dramatically.

The continuos release of sulphur dioxide into the atmosphere leads to a warming effect and forces the temperature up.

We are already beginning to see drastic climate changes, but in the next 50 years whole eco-systems and environments may be destroyed because of this warming effect.

The Arctic circle as we know it today may seize to exist taking with it its’ inhabitants such as the polar bear.

Scientists first started looking at alternative forms of energy when they realized that fossil fuel resources are running out quickly and that the damage to the environment caused by the burning of such fuels was taking effect much more rapidly than anticipated.

We are now at a point where a wise decision needs to be made quickly.

Considering the many wind energy advantages, it makes sense to develop the wind industry much further.

Apart from the wind energy advantages mentioned above, the wind power industry can even help during the current global recession.

Investing in wind power at a national level can bring a major economic boost to our economy and create an abundance of new and well paying jobs for people.

In addition, new businesses could be formed providing a vast array of services, from installation and maintenance services to books and publications on how to build your own wind turbine, DIY kits etc.

The many wind energy advantages definitely outweigh any of the disadvantages of this new technology.

If we aim to preserve our beautiful environment for as long as possible, our society has no other option but to embrace wind energy.

Wind Energy Disadvantages

Wind energy is generally seen as a clean and environmentally friendly energy source.
While this is certainly true there are some wind energy disadvantages that are sometimes overlooked.

Click Here for the ultimate practical insider guide to benefit from Wind Energy Disadvantages.

Wind energy is derived from the sun. It is the sunlight that warms the earth during the day. During its’ absence at night time, however, the weather cools down. Due to the earth spinning, day-time and night-time or warm and cold periods alternate and hence wind is created.

Wind energy is not a new thing. In the middle ages it was used to mill grain. In China people used wind energy for many centuries to pump water.

However, after the discovery of fossil fuels wind energy became less popular.

Today, due to our environmental problems people are starting to look at wind energy again. Especially the fact that wind does not generate any gases is seen as one of the real advantages of wind energy.

But we also should keep the wind energy disadvantages in mind, too.

The wind energy disadvantages are few but they are nevertheless very important.

The biggest disadvantage of wind energy is the noise that wind farms create. Each wind turbine currently emits some noise. On its’ own this noise is unproblematic. But in a field of hundreds or even thousands of wind turbines the noise emission is huge.

To get a better idea of the level of noise we are talking about, commercial wind turbines are often compared to jet planes.

Critics of wind energy therefore claim that one is only exchanging one kind of environmental pollution for another one.

Due to the noise emission people are unwilling to accept wind farms in their neighborhood. The extensive protest of people against the building of wind farms close to residential areas puts the governments under severe pressure.

Noise emission is not the only reason for people’s protests. A lot of resistance against the development of wind farms comes from the fact that they are considered an eye-saw.

Another one of the major wind energy disadvantages is the fact that wind itself is not constant but unreliable.

One day you might have strong winds blowing, and other days there will be no wind at all. We need to be able to store wind energy so that people don’t go without energy when it is not windy.

There are other wind energy disadvantages that do not automatically spring to mind straight away when thinking about wind energy as a power source.

These disadvantages include the high initial start-up cost to set up the wind power technology, necessary governmental permissions, required land consents and actually having to find land big enough for a wind farm.

In today’s densely populated world it is often hard to find land that is big enough to house the wind turbines and close enough to where people live.

Putting a wind farm too far away from the households that are suppose to use the generated power can turn the whole concept uneconomical.

Overall wind energy has many advantages to offer. But wind energy disadvantages and problems need to be solved before wind energy can really emerge as a global alternative energy solution.

Alternative Wind Energy

Alternative wind energy is using the energy contained in wind to generate electricity. Wind itself is caused by imbalances in atmospheric temperature. These imbalances in temperature are caused by the fact that the sun constantly heats up different parts of our atmosphere while other parts are cooling down leading to changes in weather patterns.

The actual strength of the wind is also influenced by other factors such as proximity to mountains or the sea.

Winds are typically stronger and more frequent in the open sea and scientists are constantly looking for ways to built wind farms “off shore” in the ocean.

Windmills are an early technology to harness the power of the wind. They have been used for centuries to grind grains in Egypt and pump water in China.

However, the first wind turbines that generated alternative wind energy were used in Europe in the middle of the last century.

The principle that underlies the traditional windmill also underlies the wind turbines of today.

Just like solar energy, wind energy is also a free and renewable resource that is not going to run out in the near future. It is said that we could comfortably satisfy all our energy needs with wind power alone.

The World Energy Council has stated that one per cent of the alternative wind energy available would be enough to meet all of the worlds’ energy needs.

Nevertheless, we are still powering our world with fossil fuels that cause great damage to our environment. High levels of greenhouse gases and other pollution in the air are the leading cause of global warming.

Some years ago, nuclear power was perceived as the answer to our energy problems. However, like fossil fuels nuclear power also caused many difficulties and dangers to us and our environment as the disaster of Chernobyl demonstrated in 1986.

One of the few drawbacks of alternative wind energy is the fact that wind farms need wind and preferably lots of it.

Therefore, you can find many of the largest wind farms in places with strong and frequent winds such as the state of North Dakota in the United States and Wales and Scotland in the United Kingdom.

North Dakota actually has the potential to generate more alternative wind energy than all of Germany but not enough technology is installed yet.

At the moment, Germany still has more wind capacity installed than the United States. Currently, Europe is dominating the wind industry, but the United States have the fastest growing wind market.

If President Obama has his way the United States will overtake Europe as the leader in the wind industry in a few years.

The main reason for the current growth of the wind industry is the fact that initial setup costs are falling. Fossil fuels are non-renewable resources that will be depleted soon.

Electricity prices are rising fast and especially during this global recession people are looking for ways to cut costs.

Alternative wind energy is free except for the cost involved in purchasing land and building wind farms, or making and installing wind turbines in your own back yard.

The government is also offering tax incentives to make use of alternative wind energy instead of traditional energy sources. Those state incentives were very successful in motivating people to install their own wind systems.

The Federal Production tax credit has also proven to work very well in promoting the usage of domestic wind power.

Renewable Wind Energy

For centuries windmills were used for pumping water or grinding corn. However, at the beginning of last century the internal combustion engine replaced the windmill and with it the usage of wind power.

Renewable wind energy is actually indirectly powered by the sun. Solar energy warms the atmosphere which then in turn cools down again which causes the wind to develop.

By the end of the 19th century (1890) special windmills known as turbines designed to generate electricity were popular in Denmark .

These turbines had two or three rotor blades attached to the shaft of an electricity generator. Through the wind spinning the blades, the generator turned and produced electricity.

Today, renewable wind energy has become more interesting again and it is said that in the next 10 to 20 years a large part of our electricity may come from renewable wind energy.

However, much more research and development needs to be carried out before those claims can become reality.

Compared to the burning of fossil fuels renewable wind energy has a number of advantages. These include:

• Wind is a vast and renewable natural resource.
• The maintenance and operational costs of a wind system are very low.
• The usage of other more harmful sources of energy such as natural gas and coal can be decreased.
• Wind power does not produce any greenhouse gas emissions.
• Wind is a freely available natural resource.
• Power from wind energy is less expensive than power from nuclear plants or gas.

Of course there are many more benefits to the usage of renewable wind energy and the list above is by no means exhaustive.

The potential of renewable wind energy is so great that up to 50% of the electrical power needs in the United States could be satisfied by wind power. However, currently not even 1% of all electricity comes from wind power.

Renewable wind energy could certainly be developed as a major energy source in the future. Globally, the United States shows the fastest growth rate for the usage of renewable wind energy.

Wind energy needs wind to function. Therefore, places with stronger or more frequent winds such as North Dakota and California have attracted more wind farms.

Due to the large areas of land required by wind farms they are occasionally erected on farm land. But before a wind farm can be built there are numerous things that need to be considered.

Wind farms require winds of certain speed and certain consistency, too.

Offshore locations also look very promising for the erection of wind farms as winds blow strongly and frequently out in the ocean.

Financial incentives by the government could encourage further growth of the renewable wind power industry to develop to its full potential.

State incentives have already been successful in the development of small wind systems but currently they are only available in California, Massachusetts, New York, Ohio, Pennsylvania and Wisconsin – hopefully more areas will be added soon.
