Onshore wind energy

Iberdrola, a global benchmark in onshore wind

At Iberdrola we are committed to wind energy, which transforms the power of an inexhaustible resource such as wind into electricity, as a sustainable and valuable investment for the future.

With more than 20,800 MW of installed capacity worldwide, the group continues to lead the field of onshore wind energy, to which 28% of the investment in renewables in the new Strategic Plan to 2026 will be allocated to increase its installed capacity in this technology.

What is onshore wind energy?

Onshore wind energy is generated by harnessing the power of the wind - the movement of air masses - through wind turbines located on land. Thanks to their blades, these wind turbines transform kinetic energy into mechanical rotational energy, which is then used to produce electricity that is connected to the distribution networks. Wind power is a renewable, clean and inexhaustible source of energy that has been used for centuries, with the technologies available at any given time and with different functions. 

In addition to onshore wind energy, we also have offshore wind energy, which is produced in the same way through wind farms in the sea. All in all, wind energy is a sustainable, local-economy-boosting and future-enhancing energy source

What are onshore wind farms like?

Onshore wind farms are basically made up of a set of wind turbines (of different powers and sizes depending on each wind farm), transformers (which raise the electricity from low to medium voltage for distribution throughout the farm), and an electrical substation, responsible for converting the energy into high-voltage current, suitable for transporting the electricity to the installations connected to the distribution network.

 Onshore wind farms are installed in locations where data support the prediction of adequate wind quantity. In addition, these onshore wind turbines, which can reach heights of more than 150 metres, coexist with agriculture and livestock farming.

The rotor is the element made up of the three blades of a windmill and the hub that joins them together.
Its function is to capture the force of the wind and convert it into mechanical rotational energy.
Depending on its size, the power of a wind turbine varies.

What is wind energy, how is it converted into electricity and what are its advantages?

Wind energy, which transforms the power of an inexhaustible resource such as wind into electricity, is a sustainable and valuable investment for the future. Harnessing the wind requires the installation of wind farms, either on land or offshore, with dozens of wind turbines. Find out how this energy is generated and how it is harnessed.
