Un mondo alternativo di energia

Wind Energy


Wind energy is the product of the conversion of the kinetic energy of the wind into electrical energy by wind turbines. The principle is the same as the old windmills, with the difference that, in this case, the rotational movement of the blades is transmitted to a generator that produces electricity.

A wind power plant generally consists of a tower fixed in the ground, on top of which the wind generator is mounted, consisting of a series of blades (usually three) and an alternator.

Wind generators are classified into two categories:

Vertical axis wind generators, adjustable in order to exploit any prevailing wind direction.
Wind generators with horizontal axis, in which the rotor is oriented perpendicular to the direction of origin of the wind

Applications and advantages

The mini wind turbine, thanks to its small size and ease of installation, is perfectly suited for insertion in companies and private homes. Its applications vary according to the electrical power supplied by the system. The production of electricity deriving from the mini wind is in fact able to satisfy the amount of energy necessary for energy consumption not only of private homes and offices, condominiums, farms, farmhouses, but also for tourist villages, campsites, production companies and processing of agricultural products, small industrial or artisan businesses, public offices, schools, gyms, communities.


In fact, exploiting wind energy offers the advantage of accessing the green certificate mechanism. The current legislation encourages the installation of small wind plants, both from a bureaucratic point of view (with a quick authorization process) and from an economic point of view, thanks to very high incentive rates that allow rapid recovery times of the investment.

The D.M. of 6 July 2012 "Renewables Decree" provides for an incentive of 0.291 € / kWh for wind farms connected to the electricity grid with a power between 1 and 20 kW and of 0.268 € / kWh for wind plants connected to the electricity grid including between 20 and 200 kW (All-inclusive Fixed Rate). This incentive is paid by the GSE (Energy Service Manager) for each kWh fed into the grid and has a duration of 20 years. At the end of this period, the energy produced can be sold to GSE through the dedicated withdrawal mechanism.

Alternatively, after signing a specific agreement with the GSE, it will be possible to benefit from the on-site exchange mechanism. The latter is an alternative to the all-inclusive fixed rate and cannot be combined with it.
