More and more talk about renewable energies. Not surprisingly, it is about the energies that can offer a solution to the high and growing energy demand that we have to face as a consequence of the demographic increase that the entire planet faces. In fact, renewable energies are the only ones that will really be able to offer a solution to this demand, since they are those that are not exhausted, since they “renew” naturally. There are different types of these energies. Would you know how to say yes The sun is a renewable energy? And, if so, would you know what its most important advantages are? If you want to know the answer to this question, keep reading ecology and we tell you.
What are renewable energies
Renewable energies are those that, regardless of use that is made of them, They are never exhausted. In fact, when talking about renewable energy, we can also talk about inexhaustible energies, since its use does not reduce the amount of the source in question and, therefore, never runs out.
In this way, when we talk about renewable energy, we are referring to some energies such as:
- Wind energy
- Hydroelectric energy
- Mareomotor energy, undimotor and so on.
In the following article of Ecologiaverde we also talk about what renewable energies are.
On the contrary, when talking about non -renewable energies, we are talking about energies that, with their use, end up ending. Two of the clearest examples of non -renewable energy They would be coal and oil That, apart from the pollution they generate, when consumed, energy can not be produced again from them, which does not happen with renewable energies.
Is the sun or not a renewable energy?
Indeed, The sun is a renewable energysince it can be used as much as you want to get energy and never exhausted. Naturally, when we talk about renewable energy, including solar, and we say that they are renewable or inexhaustible energy sources, we are saying it from a human perspective. That is, naturally, the energy of the sun will end up exhausting when the star of our solar system exhausts all its hydrogen fuel, which is the original source from which its energy proceeds. However, in the time scale of the human being, this energy It is virtually inexhaustibleso it can be considered without a doubt as a renewable energy.
It is important to keep in mind that, in addition to being a renewable energy, solar energy is also especially abundant in all points of the planet. Of course, in the latitudes closest to Ecuador, as well as the most sunny days, the solar energy of which you can make use in greater. However, even in regions near the polar circles, and also the cloudy days, energy can be obtained from the solar radiation that reaches the surface of our planet, which makes it One of the potentially most usable energies of those that exist.
TYPES OF SOLAR ENERGY
In addition, another factors that must be taken into account is that the energy of the sun reaches us in several ways, that is, by light and heat. This means that, when talking about solar energy, the right TYPES OF SOLAR ENERGY:
Photovoltaic energy
The type of solar energy that It is obtained From sunlight It is photovoltaic solar energy. It is the best known of all, since it is the energy used by solar panels, which are the main instruments that can absorb this energy and turn it into useless electrical energy for the needs of the human being. The advantage of this energy is that it can produce Large amounts of electricitythe disadvantage is that Requires a large surface To do this. However, with current technology, photovoltaic energy is especially useful when satisfying the energy needs of small electrical installations, such as those that may have independent houses, industrial buildings that do not require much energy, or urban or road furniture.
Thermosolar energy
In this case, we are also talking about solar energy, but of which is obtained from heat That comes to earth. In this case, these are facilities larger than the solar panels, being true energy plants that offer their supply from the energy they produce. In this case, what is done is to reorient solar radiation through mirrors to the same point, which concentrates a lot of heat. This heat is transformed by a mechanical system in motion that, in turn, becomes useful electrical energy For human needs. This type of energy is intended to offer a broader energy supply, similar to the public supply system that reaches most real estate and spaces connected to the public electricity grid.
