Since Don Quixote de la Mancha’s times (or even before), wind energy has been used to aid us on several daily life activities. Wind energy can be utilized in order to grind food grain and even to pump water: that’s what windmills do. In this case, wind energy is used to get mechanical energy to execute such activities.

But when a windmill turns into a wind turbine, it can provide electricity to power our homes. In that case, we talk about wind generators. Big farm plants of wind turbines (also called wind power units or WPU) can impart much power with which many homes can be provided with the electricity they need. On the other hand, we can also make a simple wind turbine to provide our home with free, inexhaustible and clean electricity.

As we surely know, to get the required items and hardware in order to implement a home solar energy system for our house is rather expensive. Not so with wind power: the creation of a wind energy generator is relatively cheap and not very difficult to implement either.

The convenience or not for introducing a wind energy system in our home is quite obvious: wind turbines should be set in windy places. If this is not the case of our place, it is better to go for another alternative energy system like a home solar system or a magnet-based generator. Nonetheless, if you can make a wind turbine near your house in a place where wind blows quite consistently, that can be a very good option to, for example, a photovoltaic energy system that requires quite expensive solar panels.

I always wonder why initiatives regarding the introduction of these clean, free and non-polluting energy sources are not more boosted by everyone. Nowadays, we go on not only wiping out the oil sources of our planet but also polluting our environment with the products derived from it. There are certainly some efforts in many countries and from different companies to implement clean and renewable energy systems in some cases. Nonetheless, all this is almost nothing if we take into account how bad we are dealing with our planet and our fellow living creatures (animals and plants) by polluting and annihilating their habitats and environment, and hence our own habitat and environment too.

For example, why do we not mass-produce electric cars only? Forty years after we landed on the moon it is hardly believable that we do not possess the needed technology to produce electric cars better than the best conventional cars today. What is more, if a great amount of wind farms were set up, the energy all those cars needed could be easily obtained… for free! Of course the firsthand investment in order to implant so many wind energy units would also be significant, but then the investment would pay off many times.

As it seems, we live in a kind of a crazy world where common sense is the less common of senses, as it is said… However, we can always do something for ourselves, for our planet and hence for everyone who lives on it. So, every effort we make to introduce and encourage the creation of renewable energy systems like a wind power electricity system, will be a good, convenient and honorable deed.
