Wind Energy Facts

Ever experienced the cold fresh air blowing through your face when you’re hiking up in the mountains? These strong winds hold enough power to change the world we live in.

There are plenty of wind energy facts, covered in this article, that will blow your mind. But first, let’s look at the current situation of energy consumption around the globe.

The present most dominant source of energy is coal, followed by natural gas, nuclear, and hydro. But will these sources remain in the front positions for long?

Absolutely not!

Let us explain why.

First of all, the side effects brought by extracting natural gas and burning coal are causing the entire world to suffer. The alarming rate of ozone layer depletion and the increasing pollution in our surroundings are just a few effects caused by them.

In recent decades, humans have become much more conscious regarding the harm caused by the consumption of these energy sources to the environment. It’s time for a change!

Wind power, just like solar energy, is one of the most efficient, cheaper, and less polluting renewable sources of energy on the planet. Not only does it free up the surroundings of polluting substances, but it is one of the most accessible sources of energy extraction.

With the advancement of technology, the installation and production of wind-powered energy are getting surprisingly more straightforward. It can turn into the dominating source of energy in the coming future.

Let’s hope for that.

For now, let’s get informed about what wind power is. You’ll gain insight into a vast world of wind energy production with the 50 facts mentioned in this article.

What is Wind Energy?

If you’ve traveled by sailboat or have seen a windmill, then you might have some idea of what wind energy means.

When you’re on a wind-powered ship, its sail propels itself directly towards the wind’s direction. Wherever the wind is flowing, the ship sails exactly to that direction. Similarly, the blades of a windmill rotate either horizontally or vertically. No matter which direction it turns at, it works only in the presence of wind.

Why do they only work int the presence of wind?

It is because they are powered solely by wind energy. Alternatively, you can say wind power. Wind energy is one of the most readily available renewable sources of energy, which is also the cheapest among all.

Besides being the cheapest source of energy, it is also one of the cleanest means of energy. The wind turbines that generate electricity out of wind power do not emit harmful gases.

Being one of the safest and most accessible sources of energy, a large number of countries have started adopting its usage to fulfill their power requirements. Although having multiple purposes for this source of energy, the most prevalent use is to generate mechanical power or electricity.

How Does Wind Energy Work?

 

Now that you’ve gained insight into the concept of wind energy, you might be wondering how it works. The extraction of wind power is among the easiest, among other renewable energy sources. Depending on the intensity of the wind, it brings a particular device into action that converts the kinetic energy into other forms of energy.

Let’s take a wind turbine, for instance. Such turbines are incredibly tall and slender shaped structures with four rotating blades attached at its top. When these blades get hit by wind, the pressure across one side of the blade decreases, leading to several phenomena, and in the end, it rotates.

The rotation of its blades causes its internal rotors to spin. The rotors connect to its generator that converts the mechanical energy of the rotation into electricity. The electricity then transfers to the grid, which later powers households, industries, and other purposes.

Apart from converting it to electrical energy, you might use the mechanical energy generated from wind for various purposes, such as pumping water, grinding gains, etc.
