Why WindEnergy?

The increasing pressure of global warming combined with the constant rising price of fossil fuels forces us to come up with new ways to produce energy.
Using the power of wind is not new for us; there is evidence that wind energy was used to propel boats along the Nile as early as 5000BC. But only recently we started to use the wind power to create electricity.

Wind energy is actually based on solar energy; about one to three per cent of solar energy reaching the Earth is converted into wind energy. Therefore it is a clean, renewable form of energy and the advantages of using it are obvious.

On a large scale wind energy is converted to high voltage electricity with the help of wind farms. Compared to the environmental effects of traditional energy sources, the environmental effects of wind power are relatively minor. Wind energy emits no air pollution and consumes no energy, unlike fossil fuel power sources. According to the Department of Energy, offshore wind farms could provide enough energy to power the entire nation.

On a small scale wind turbines can be build and installed for personal use by anyone with less than minimum technical skills. Once installed it is one of the cheapest forms of electricity generation to maintain.

Today Germany is the world leader producer of wind energy, with US on the third place. In Denmark, wind power now produces approximately 20% of the country's electricity consumption, and in recent surveys, 90% of the citizens wanted more wind turbines installed. The United Kingdom plans to use offshore wind turbines to generate enough power to light every home in the U.K. by 2020.

The most serious environmental drawbacks to wind machines may be their negative effect on wild bird populations and the visual impact on the landscape. But not for everyone; in the UK, repeated opinion surveys have shown that more than 70% of people either like, or do not mind, the visual impact.

However, wind is the fastest growing energy source worldwide. The drawback is very little when compared to what is gained and the world is starting to realize that.
