Harnessing the wind power

From the earliest moments of his life, man has exploited the resources that the environment offered to him: sun, water, air. With the passage of time and technological innovation, we tried to figure out how to best exploit these resources aiming to safeguard the environment.
The wind and its movement gives rise to wind energy. In fact, through the displacement of air masses from a high pressure zone to a low pressure one, it generates energy, a particular type of energy that takes the name of wind energy, which is identified with kinetic.

Wind clean energy

The wind has a great importance in nature, in fact it is exploited by birds to fly, plants for pollination and, along with the ocean currents, creates waves on the sea, the wind mill instead is usedby men to produce energy. The first instrument built by man to harness the wind was the mill which is still used in many countries of northern Europe. The windmill, through a system of spinning turbines, produce electricity via a generator. Slowly then exploiting this principle so simple it has gone to the production of energy on a large scale.
If you produce clean energy through the harnessing of wind, you can have an amazing array of benefits especially in economic terms, just think of the fact that one watt of energy produced through wind costs about 1.5 euro against 5 of the normal energy.

How to harness wind energy at home

In recent years, when it comes to energy production, we are always trying to look to the preservation of the planet, or energy, trying to make the smallest damage as possible to the environment that surrounds us. The ever increasing cost of energy has gone, then one of the main objectives of people is to save money.

The principle that allows us to get electricity from wind is very simple and is based on the movement of the propeller blades, precisely due to the blowing of the wind at a higher or lower speed. These blades are connected to a generator and convert the mechanical energy that is generated as a result of their rotation into electrical energy. A plant of this type takes the name of facility of wind turbines.

This system is now being used to produce electricity on a large scale, but being able to use the wind power at home, could be used for the preservation of our planet at the same time allowing us to live better. To realize this system should install the fan, obviously small, on the roof of our house so as to produce and store energy.

The energy produced in fact fully satisfy the needs of the individual dwelling, at the same time allowing us to resell the network's energy produced in excess. In this way the individual user would get a double benefit, namely an immediate saving as regards the bill, as this would reduce costs alone without management meter the consumption and could even be a gain related to the sale of excess energy produced at the network. The wind power plant in the collective imagination is thought of as a system of enormous dimensions, consisting of massive blades placed in areas of relatively highness and wind.

But modern technology, on the other hand, has allowed us to obtain plants suitable for housing, so small in size that they can be installed very simply on the roofs of houses and buildings.

Technically, the wind farm is nothing more than a series of vertical-axis turbines, which have a series of magnets, which are able to capture the energy of the wind at its highest point, or when the wind is stronger, ie at a greater speed. These turbines are capable of producing up to 1500 kWh per year of energy and can operate even in light wind, so we are talking about very low speeds. The structure of this type of wind turbine system has been studied reduced so as not to risk that the blades become broken and then to fly on other dwellings.

The wind power is one of the renewable energy sources that are available in nature, as an alternative to wind energy is important to know that you can also take advantage of the solar energy, or water energy. If you go to one of these alternative sources, it makes a very clear choice that will allow us to not only save the environment but also ensure a better future for the new generations.
