Wind energy means the extraction of wind kinetic energy for the production of mechanical or electrical energy.
During the day the air above the seas and lakes remains colder than the air above the earth, mainly due to the fact that the water “absorbs” the solar heat in the lower layers, on the mainland instead the solar heat comes in good part of the reflection and heats the air on the surface which expands becomes light and tends to rise, consequently the colder and heavier air that comes from the seas and oceans starts moving to take its place causing the surface winds , at night the opposite usually happens as the heat accumulated in the deep layers of the water make the air above the bodies of water that tend to rise warmer and the air above the earth, colder because it is no longer radiated by the sun tends to take its place, so there is a breeze towards the mainland during the day and a breeze towards the sea at night.Other causes of displacement of air masses are fluctuations in atmospheric pressure, for this effect the air is moved, on the ground, from areas of high atmospheric pressure to areas of low pressure, with speed proportional to the pressure difference. Before installing a wind turbine, it is advisable to carry out anemometric measurements that give a general picture of the wind characteristics at the exact installation point. question. The wind turbines that we increasingly see in our countryside or mountains are composed of several components.
The rotor blades are generally made of fiberglass and can rotate at speeds of up to 200 km / h driven only by the wind. The motion of the rotor is transformed into electricity by the generator using the same principle as the dynamos mounted on bicycles. The work that a wind turbine can do depends on the area of the rotor and on the aerodynamic efficiency of the rotor.

The plants are divided into:

  • isolated systems (few wind turbines)
  • cluster plants (“Wind Farm”) (wind turbines connected to a local network)
  • combined and integrated systems


The wind turbines are grouped by means of well-defined clustering techniques and still constantly updated. The diffusion of wind energy allows the improvement of the techniques of disposition of wind turbines to make them more and more optimal and effective in the morphological context of the territory.
However, it will be important to ensure that the impact on the landscape is taken into account in the arrangement. Especially in the cases of large wind farms.

Finenergy realizes the Small Wind systems up to 60 KwE per blade. Even today, these systems enjoy state intentions and, in addition to producing a considerable amount of energy per year, they are very convenient from the point of view of investments or self-production for adjacent sites.
