Image description

The image shows a landscape in which four wind turbines are captured, these being dispersed on a field, depicting a scene of wind farms, viewed from the front.

The relief of the plain spread with mounds or rounded heights in the form of domes in some places, is rendered by the texture of sloped pluses, being located at the base of the turbines.

The turbines are highlighted embossed, being made up of the following components:

  • the high support pillar, called the tower, rendered by a vertical and thin rectangle, conical towards the top;
  • At the top of the tower is mounted the rotor with the rotor axis rendered by a small and embossed circle
  • Three elongated circular blades with narrow ends are attached to the rotor.

General information

After the discovery of the utility of the electric current, interest in its generation methods increased. At first, electricity was only available in places where there were individual power generators. For this reason, it was necessary to create an electricity generation and distribution infrastructure to ensure the supply of electricity to a wider area. The infrastructure has been created and so we have electricity in almost all populated areas of the Earth. This infrastructure is called an electricity grid. The main components of the electricity grid are the power plants in which the current is produced, the transformer stations that adjust the voltage according to the needs of the consumers, and the cables through which all elements of the grid are interconnected. Also, through the cables, the current reaches the consumers.

Power plants are of many kinds, depending on the energy they use to produce electricity. Thus, we distinguish: thermal power plants, hydropower plants, wind power plants and nuclear power plants. All power plants have as their main component electric generators, which convert mechanical energy into electricity.

Wind force is an alternative energy resource. It can be converted into electricity using wind power plants. Wind turbines take wind energy and turn it into rotational motion, and rotational motion is transmitted to electric generators.

The main components of a wind turbine are: the blades and the rotor, respectively those which rotate at the action of the wind; the axis, the one that takes the rotational motion of the rotor and transmits it to the electric generators; electric generators, respectively those items that produce electricity.

As with photovoltaic panels, the energy generated can be stored in batteries, or it can be introduced into the national electricity grid. The only drawback of wind power plants is that they can only be operated in areas where winds are present most of the time.

Did you know that modern wind turbines automatically adjust their position depending on the direction of the wind? This technology is also used by photovoltaic parks, where panels are automatically positioned in the direction where sun exposure is higher. Through this process, natural energy losses are lower and electricity production is higher.

The world’s largest wind farm is located in the United States and houses over six hundred turbines.
