Wind is a powerful source of energy which, for centuries, has been harnessed for different uses. More and more scientists and researchers consider that wind can be used effectively as a clean renewable energy source. But this can only be done when power within the moving air is harnessed properly.
The Wind Energy Industry has grown rapidly since the 1990’s and is considered to be one of the fastest growing sectors in the power generation industry. Some European countries have installed wind turbines that have now been in operation for almost 20 years now, and this entire operation has been quite successful as well. Using wind turbines to create energy has brought down energy production costs, and is a viable option for the replacement of coal-fired power stations.
According to one study, the UK has the largest potential wind energy resource in the entirety of Europe. Wind is therefore regarded as their most promising future source of renewable energy. Currently, wind turbines in the UK are producing electricity which is delivered to almost 390,000 households, and is reaching around 1 million people. Furthermore, the use of wind energy has reportedly reduced carbon dioxide emissions by almost 1.46 million tones per annum.
How is wind converted into energy? With a wind turbine. The wind turbine is basically a rotating device, like a huge fan, whose blades turn when the wind passes through them. They convert the wind’s kinetic energy into mechanical energy.
When this mechanical energy is used by any type of machinery (such as a pump) then the machine is known as a windmill. If the same mechanical energy is converted to electricity, then the machine which does the conversion is called a wind generator or a wind turbine. It is also sometimes known as a wind energy converter (WEC) or a wind power unit (WPU).
The first use of the wind in machines was actually for grinding grains, as early as 200 B.C, in Persia. It was later introduced into the prosperous Roman Empire in 250 A.D. The year 1900 saw the maximum number of windmills in use in the country of Denmark. Almost 2500 windmills were installed at that time, to provide the much needed mechanical load to pumps. They gave a peak power supply of 30MW.
Why Should Wind Turbines be Used?
Wind turbines can effectively help to create mechanical energy, which can then be used for multiple purposes, such as the generation of power and electricity.
Some of the other uses include the following:
- There is only a one-time installation cost for setting up a wind generator, after which the electricity produced by the wind turbine will be free.
- It is a source of clean and renewable energy which will not generate any greenhouse gases, nor emit pollution or even produce any dangerous waste material.
- Each unit of electricity produced by a wind turbine replaces a similar unit of energy from a conventional power station. Wind turbines have highly successful where they have been commissioned in the UK, preventing the emission of almost 1 3/4 million tonnes of carbon dioxide per year.
- Wind is an abundant and reliable source of energy. The UK, possibly being the windiest country in Europe, has abundance of wind energy which is used for making electricity. As do other windy areas such as Denmark and other parts of Scandinavia.
- Wind power contributes significantly to the overall energy production of any country. Denmark is one country which gets almost 20% of its electricity from wind power.
- Wind turbines use an extremely robust technology, which is designed for both local operation as well as for remote operation, and requires only periodic maintenance.

WHAT ARE some “OUT of the BOX’ uses for wind generators BESIDES just power???
This article provided many useful information about the use of wind turbines. This is a good source of generating electricity instead of using fossil fuels. You are not only saving the environment but at the same time you are saving money from electrical bills.
Didn’t know that they already use wind for grinding grains since 200BC. Having a wind turbines at home may be cost you high but the benefit on energy efficiency is worth to pay.
i agree with this article. It’s really great to have windmills as your own source of energy. Although most of the time having one windmill is not enough to support your electricity consumption. It’s best to have a solar panel with a windmill to boost the energy production. we should all create our own alternative energy sources because not only it will save us some bucks, but it will also help in saving our planet. cheers!
Hi Anna, Good article about wind turbines and wind energy. The only thing that could be included is that when the wind isn’t blowing and your turbine is not generating energy you are able to store some of that energy. The stored energy then powers your home. If you ever want to write an article for our news site, please send me an email. All the best, Kilarin
Thanks for sharing this. I think wind turbines should be found in every yard. I`m building a house and i`m thinking of using a small wind turbine.
Nice post Anna. People should really consider the great benefits of the Earth. Be it Solar, Water or Wind. Through this method, we can really reduce our electric power consumption and bills. Though it’s expensive, just realize the benefits and worth you may get on this alternative.
Installing home wind turbine is high cost. But the benefit on energy efficiency is worth to pay.
Aren’t Home wind turbine very expensive?

I agree, though wind, solar and other alternative energy sources has their own downsides.

Great read Anna. Growing up on a farm we used the wind to pump water for our cattle to drink, and for our home gardens. What a great resource we have. I currently have a home built wind generator that helps reduce the green house gasses and saves me money. I look forward to reading more here.

Great article… Wind turbines are a great way to make energy and save money
Great post about one of the less used energy sources. enjoyed this article a lot
I had no idea that they used wind for grinding grains in 200 BC, which is especially impressive since it is a technology that is still used today. They must have been way ahead of their time!
your posting its fantastic…i learn a lot from your articles…
