Wind turbines – white structures with three or more blades which are used to generate electricity from the wind – are one of the most efficient methods of generating renewable energy.

This is simple fact, and the continued development and licensing of turbines is further testament to this.

The reason for this general opinion is that, when one views the statistics, wind turbines are powerfully useful. For example, with older energy generation techniques such as using fossil fuels, to generate electricity one must use some of the earth’s natural resources. In the case of fossil fuels, these one day will run out.

Wind turbines have no effect on the earth’s composition and do not need to dig into anything to be able to generate. They take nothing from the earth as an organism, and this makes them a mighty weapon in the battle against climate change.

Wind turbines do not produce any emissions, be it carbon dioxide – the cause of climate change – or other such chemicals which may be harmful. Though the construction of a wind farm or turbine requires electricity and source material, it is estimated it takes a mere nine months for a single wind turbine to ‘pay back’ what is has taken out. What is more, after that initial nine months pay back time, wind turbines do not require anything but the wind to operate.

The biggest benefit of wind turbines, however, is that they take a natural source and make it useful. The wind blows everywhere in the world, and all wind turbines do is take the previously unused kinetic energy of natural weather phenomenon and create usable electricity.

Put simply, the benefits of wind turbines and wind power are overwhelmingly convincing.

We live in an energy conscious world today and more and more people are seeking ways to reduce carbon emissions and help protect the environment. Cutting down on fossil fuels and the use of renewable energy is a key part of protecting our planet.

Wind power has emerged as one of the most effective ways of harnessing the Earth’s natural resources to produce a clean form of energy that doesn’t damage our environment.

There are several advantages of wind power and as oil prices continue to rise and pressure mounts to cut down on carbon emissions, the benefits of wind power and other alternative energy sources are becoming more and more apparent.

According to experts, wind power could meet 10 per cent of the world’s electricity within 20 years, even if the amount of electricity used doubled. At present, the annual growth rate of wind power is more than 40 per cent and it should soon supply electricity to 100 million people worldwide. Europe is currently the world leader when it comes to wind power with Germany and Spain providing the most electricity through wind power. The United States is third on the list, followed by India and Denmark.

Wind power is the fastest growing source of alternative energy in the United States and around the world. Every year, more a more households get their electricity through wind power. However, this cheap and clean source of energy is still only being used to a fraction of its potential. However, this is likely to change in the next few years for a number of reasons.

Wind power is clean

The chief advantage of wind power is that it is clean. There is no smoke, no fumes, no smog and no dirty air for us to breath. A turbine simply harnesses the energy of the wind and produces electricity without producing any waste whatsoever.

Wind power can produce electricity that can be fed directly to homes and factories, replacing the power supplied by major power plants. Today, power plants are among the biggest polluters in the United States. However, a single 1-MW wind turbine can save on 2,000 tons of carbon dioxide in one year. This is the same of planting one square mile of forest. And that is just from one turbine, imagine what one hundred turbines will do to help save our environment.

Windpower is cheap

Wind is free so wind energy is cheap. In fact, it is the most competitive of all the renewable energy sources when it comes to cost and can easily rival the cost of other more tradition fuels like gas or oil.

Wind power is a relatively new technology and at the outset it was quite an expensive source of power. However, developments in the technology means that costs have reduced drastically and are continuing to fall. Meanwhile, the cost of power provide by fossil fuels is going up so wind power is likely to become the cheapest for of electricity in the near future. And once it becomes the cheapest, we can expect to see a significant rise in the number of wind farms in the United States.

Wind is everywhere so there is the potential to build wind farms anywhere. Of course, some areas are better than others for harnessing wind power but the ability to have wind power as a local source of energy is a real plus. It can save on miles and miles of cabling, provide jobs and investment in local areas, and generally boost local economies.

Wind power also benefits society on a wider level. It makes for a cleaner environment which means healthier people and fewer air pollution-related medical problems. It can also be put in place quickly, cheaply and easily to deliver a reliable source of energy in a relatively short space of time and nowadays you actually can build wind generator yourself.

What about the future?

The future of wind power is affected by any number of larger, global environmental and geo-political issues. With world leaders currently developing a new agreement on how the world is going to tackle climate change, a number of major changes can be expected in the world’s energy supply. A move to greener, cleaner sources of energy is inevitable.

This signals a busy future for wind power. At the moment we have barely scratched the surface of this valuable resource. In the United States, wind power supplies less than 1 per cent of the country’s total electricity needs. However, there is the potential to have 60 per cent of electricity supplied by wind power, and the figures are similar on a global scale.

So, in the coming years we are likely to see the number of wind farms around the world rocket as more and more countries harness this clean and cheap source of electricity.
