Non-renewable energy

Non-renewable energy

Non-renewable energies are the methods of obtaining energy through a source of exhaustible energy. The concept of non-renewable energy is taken into account at the scale of human life, since certain processes, such as the accumulation of carbon, have taken up to five hundred million years.

In general, non-renewable energy is what consumes some type of fuel (oil, coal, uranium ...). While renewable energy uses other types of energy resources (solar radiation, the kinetic energy of the wind, the force of water, the movement of the tides, etc.). Although properly speaking some fuels, in…

Renewable energy

Renewable energy

Renewable energy is that energy that comes from practically inexhaustible natural sources. They are considered inexhaustible either because of the large amount of energy they contain or because they can be regenerated naturally.

Among the main advantages of renewable energies we highlight the following:

Renewable energies are respectful with the environment and do not pollute.In this sense, they are safer and pose fewer health risks than other sources of non-renewable energy.

In most cases they are simple to dismantle and it is not necessary to guard their waste, as it…

Advantages of solar energy

Advantages of solar energy

Solar energy allows to take advantage of the energy that comes from solar radiation. One way to take advantage of sunlight is to convert the radiation into electrical energy (photovoltaic solar energy) or thermal energy (solar thermal energy). Photovoltaic solar energy requires a chemical process to obtain a continuous current, while solar thermal energy only requires a thermodynamic process.

The characteristics of solar energy imply certain advantages with respect to other sources of energy. Mainly if the other sources of energy are non-renewable energies that come from fossil fuels.…

Geothermal energy

Geothermal energy

Geothermal energy is a type of renewable energy on a human scale that is obtained from the heat of the interior of the Earth. Equestrian thermal energy can be obtained without the combustion of any material, it is therefore a form of clean energy without carbon dioxide emissions.

The temperature in the inner layers of the Earth remains constant during the different seasons of the year. Generally the inner layers are hotter than the surface in winter and cooler in summer. This is because the surface layers are heated and cooled more easily according to the laws of thermodynamics.

Solar energy

Solar energy

The term solar energy refers to the use of the energy that comes from the Sun. It is a type of renewable energy. The energy contained in the Sun is so abundant that it is considered inexhaustible. The Sun takes 5 billion years emitting solar radiation and it is estimated that it has not yet reached 50% of its existence.

Solar energy, in addition to being inexhaustible is abundant: the amount of energy that the Sun pours daily on…

Wind power

Wind power

Wind energy is the energy obtained from the wind. This renewable energy takes advantage of the kinetic energy generated by the effect of air currents, and is transformed into other forms useful for human activities. Wind power has been used since ancient times to move sail-driven boats or operate milling machinery when moving its blades.

When operating by wind, an inexhaustible resource is considered that wind energy is a renewable energy.

Currently, wind energy is mainly used to produce electricity through wind turbines. This type of energy can also be used in other applications…

Biofuels

Biofuels

Biofuels are fuels obtained from biomass (agricultural crops such as palm oil, sugar cane, soybeans, etc.) or from organic waste. The fuel generated is a liquid fuel that can be used in the engines of vehicles.

This energy source is considered non-renewable energy because the generation and recovery time of the fields is less than the consumption time.

The biofuels generated can be of two types:

  • Bioethanol, a substitute for gasoline, produced from sugarcane, beet, corn, wheat and oats.
  • Biodiesel, a substitute for diesel, produced by plants such as sunflower,…

Definition of fossil fuels

Definition of fossil fuels

Fossil fuels are non-renewable energy resources because they require millions of years for their formation in a natural way. Due to their high calorific power they are useful energy sources to generate thermal energy and their use has allowed the great economic and demographic growth linked to the industrial revolution of the 19th century. Although now they are fundamental for our economy. In 2007, the combustion of coal, oil and natural gas accounted for 86.4% of the world's primary energy. However, its combustion is one of the main sources of atmospheric pollution and global warming, which…

Hydraulic energy

Hydraulic energy

Hydropower is a source of renewable and alternative energy. This renewable energy exploits the transformation of gravitational potential energy, possessed by a certain mass of water at a certain elevation, in kinetic energy to overcome a certain difference in height. The mechanical energy obtained can be used directly to rotate the shaft of a turbine or in some application or machine that works in hydraulic power. The most common is to use this kinetic energy to generate electrical energy. In this case, we talk about hydroelectric power.

In hydroelectric power, the kinetic energy is…

Advantages and disadvantages of geothermal energy

Advantages and disadvantages of geothermal energy

Geothermal energy is a renewable energy obtained from the heat stored inside the Earth. Thanks to the laws of thermodynamics, thermal energy is transferred from the interior of the Earth to a fluid. In this way, energy is transported in the form of internal energy.

Geothermal energy is basicaly based simply on taking advantage of the fact that the subsoil temperature is warmer than on the surface, in winter, and instead cooler, in summer. This is a consequence of the fact that the surface layers of the Earth are heated and cooled much more easily than the interior, which is maintained…

Solar thermal energy

Solar thermal energy

The solar thermal energy consists of the use of energy from the Sun to transfer it to a medium that carries heat, usually water or air.

Among the different applications of solar thermal energy there is the possibility of generating electric power. The current technology allows to heat water with solar radiation to produce steam and subsequently obtain electrical energy.

Although the principle of operation is very similar there are two main applications of solar thermal energy:

  • Thermal single energy for use in homes and small installations
  • Large thermal solar…
