In Latin is where we find the etymological origin of the word energy. More exactly we have it in the term Energy, which in turn, as determined, comes from the Greek word ένέρϒεια.

The concept of Energy is related to the ability to generate movement or achieve the transformation of something. In the economic and technological field, energy refers to a natural resource and the associated elements that allow an industrial use of it.

For example: "The country has serious energy problems due to the lack of investments", "Gomez is a player with a lot of energy, capable of changing the physiognomy of the team", "In the last week, the energy has already been cut three times".

For the physical , energy is a abstract magnitude which is linked to the dynamic state of a closed system and remains unchanged over time. It is an abstraction that is assigned to the state of a physical system. Due to various properties (chemical composition, mass, temperature, etc.), all bodies have energy.

An east field, that of physics, which leads us to determine that there is mention of various types of energy in it. Specifically, we will have to deal with two: quantum and classical.

Various types of energy can be detailed according to the field of study. The mechanical energy , for example, is the combination of the Kinetic energy (which generates from the movement) and the potential energy (linked to the position of a body within a force field).

Understood as a natural resource, energy is not a good in itself, but rather that it is a qualified good as an intermediate, since it makes it possible to meet certain needs when a good or a service is offered.

Energy can also be classified by source. Is called non-renewable energy to that which comes from exhaustible sources, such as oil, coal or natural gas. Instead, the renewable energy It is virtually infinite, such as wind (generated by the action of wind) and solar.

Today, precisely, given the awareness that, little by little, society is taking on how essential it is that we undertake the protection of the environment, there is a great boom in the aforementioned renewable energies. And it is that the use of them helps us to stop exploiting other sources that pollute, that greatly harm the natural environment and as a consequence also us and our own well-being.

The basis of the use of these renewables mentioned is that you opt for an energy that takes advantage of inexhaustible natural sources, as would be the case with sunlight. In the same way you also bet on an energy that is capable of regenerating naturally and that Therefore, it does not cause any harm to the natural environment.

Thus, for example, in more and more homes the installation of solar panels is being carried out with which that light that the Astro Rey gives off is collected and it is used to illuminate any room of the house with what is decreased considerable use of electricity.

The economic exploitation or industrial energy comprises various processes, which vary according to the source used. It can be mentioned, for example, the extraction of raw material (such as oil obtained from wells), its processing (in the case of oil, its refinement) and its transformation into energy (by combustion, etc.).
