Given that the use of non-renewable energy sources generates many environmental problems, it is intended to replace them with alternatives that are truly competitive. Some are new and others, as in the case of wind energy, not so much, but almost all of them are renewable. Mankind has been using wind energy for many centuries thanks to windmills, although an improved version of these devices is currently used in so-called wind turbines, which we will talk about shortly.
Are you curious to know what wind energy is and how it is harnessed? We will tell you everything in this short article by Green Ecologist about how we can harness the energy of the wind.
We start by counting what is wind or wind energy. Wind energy is that which is achieved thanks to the wind or, in other words, it is the use or exploitation of the kinetic energy that the air masses have and that can be transformed with the appropriate methods into mechanical energy and then into electricity or whatever. another useful form of energy intended for certain human activities.
How do we take advantage of the wind? For harness wind energy Properly it is essential to know about the seasonal variations, as well as night and day that the winds may have. It is also important to know how the wind speed varies with height and the maximum values that can be reached.
Here you can learn more about What is wind energy, how it works and examples.
Wind energy is generated by using wind motors or wind machines that can transform the kinetic energy of the wind in mechanical energy that will later be used for the obtaining electrical energy. To do this, we need an electrical generator known as a wind turbine. The operating mechanism is as follows:
So that the installation of wind turbines can be really profitable, these are gathered in large groups that we call wind farms. All the electricity produced in this way is evacuated through a power line. This power line goes to a substation from which it is distributed to each of the end users.
In addition, there is talk of different types of wind energy depending on the different types of wind turbines. The main ones are:
What is wind energy used for? We are going to answer this question by taking a look at history, as one of the biggest uses of wind energy was its use for centuries with windmills. They used to grind wheat to obtain flour, they were also used to extract water and were even used in sawmills and in the production of paper. It was from the year 1979 when the wind utilities began to change and began to be used for obtaining electrical energy. Therefore, today it is used mainly to achieve electric power or electricity and to this we give infinite uses in our day to day. We use it to charge batteries, to illuminate urban centers or homes and for heating, etc.
However, its energy production varies a lot, due to changes in the wind, except for areas such as Galicia, La Mancha or Tarifa. For this reason, it is still used only as a complement to other traditional sources of energy.
To finish, we indicate what are the advantages of wind energy and its drawbacks:
The advantages of wind power they are many with respect to other energy sources. Let's see some of them:
The environmental impact of this type of energy is generally less problematic than the impact generated by other energy sources. However, it is not without its drawbacks. Some drawbacks of wind power are:
