WHAT IS ARTIFICIAL ENERGY? (WITH EXAMPLES) - SCIENCE - 2025

The artificial energy is obtained by the action of man through processes of chemical or physical transformation. The resulting products are called secondary because they are obtained from a natural or primary energy source.

In nature, energy manifests itself in various ways: heat and light, coming from the Sun; kinetic, coming from water currents, waves and wind; electrical, present in electrical storms; and human and animal, from the direct use of physical force by human beings and animals.

Examples of artificial energy

Product of the transformation of primary energy sources, man has come to generate the following types of energy:

1- Hydroelectric

It is obtained by the action of the movement of water in geodesic jumps, slopes or dams built for this purpose.

The moving liquid generates mechanical energy that activates the turbines of a generator: this is how electricity is produced.

2- Electrical

It is achieved by the action of mechanical energy from hydroelectric, wind or gas expansion sources from a heat source.

It is also obtained from electrochemical reactions within a battery or accumulator, and by taking advantage of solar energy through cells that transform heat energy into electrical energy.

3- Nuclear

It is generated by the radioactive decomposition of uranium and plutonium, mainly. This type of energy is used in some European countries to produce electricity. Alternatively, it is also used in the war industry.

4- Thermal

Also called caloric or calorific. It is obtained by the effect of vibration or movement (kinetic energy) of atoms or particles.

This type of energy is widely used in daily activities; for example, when boiling or freezing water, in fireplaces, in water heaters, home thermos, cooking ovens, incandescent light bulbs and motors, among others.

5- Wind

It is obtained from the wind, it is the kinetic energy from air currents. It has been used in windmills, pumping mills and in sailing boats.

In many countries in Europe and America it is used to obtain electrical energy through wind turbines.

6- Sound or acoustic

It is that resulting from the transmission and propagation of sound waves. It is used in the field of household appliances, telecommunications and in medicine, especially in imaging.

7- Mechanics

It is the ability of a body to carry out work when its position or speed is modified. It combines kinetic, elastic and potential energy.

It is present in almost all the human activities in which there is movement, mainly in the industrial, automotive and aeronautical sectors.

8- Chemistry

It is produced from the different chemical reactions between elements and / or substances. It is used in all forms of fuel, corrosive substances and fireworks.

9- Hydraulics

It is obtained from the potential energy of water currents, tides and kinetic energy.

It is used in hydroelectric power plants, in pumping or water mills, and especially in the use and generation of marine energy.

10- Geothermal

It is one that is generated through the use of the internal heat of the planet. Naturally this form of energy gives rise to geysers and hot springs.

It is used in desalination plants, in the manufacture of refrigerators and heating systems (air conditioning pumps) and in the generation of electrical energy.
