Wind Power Generator

What is wind power?



What is alternative energy? And what is renewable energy? As opposed to what is solar energy?
The 3 very basic questions.

The answer to what is solar energy question is already given in previous articles on this site. As explained, the solar energy is the energy from the sun that could be transformed to electricity or heat.
And what is renewable energy? Most of us know instinctively that it should be energy that could not be exhausted. Solar energy is also an example of renewable energy, it was known from the very beginning of the time and it was the first one that was harnessed.
The alternative energy is alternative to primary sources of energy, the renewable energy is an alternative energy.
Wind powerWind energy – one more example of alternative energy. Furthermore it is considered as a form of solar energy. Because of the roundness of the Earth, the air in earth atmosphere gets to a different temperature from the sun rays. Due to changes in air density and pressure air starts to move around the uneven terrain of the Earth causing the wind. The wind energy can be harnessed by people and transformed to a wind power.

So what is wind power by its definition? Wikipedia says: “Wind power is the conversion of wind energy into a useful form of energy, such as using: wind turbines to make electricity, windmills for mechanical power, wind pumps for water pumping or drainage, or sails to propel ships.”

And there are many that would agree! Furthermore, they would probably agree that wind power is very efficient and clean alternative to fossil fuels, and that wind power is renewable energy with very useful potentials just as solar power. With almost no negative effects to environment including no greenhouse gas emission, in 2011 there were 83 countries using the wind power on a commercial basis.

To finish the way we have started:
What is alternative energy? And what is renewable energy? As opposed to what is solar energy?
Those are very popular questions in days when primary sources of energy are running low, when coal, oil and gas reserves are enough for just one generation, maybe two.
The answer to what is solar energy question is the same as the answer to what is renewable energy question and again the same as answer to what is alternative energy question.
The answer is – it is our only future!
