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.

Sometimes this energy is linked to other geological phenomena such as the presence of geysers, volcanoes…

Origin of Earth's heat

Origin of Earth's heat

At the end of the 17th century, the Earth was conceived as a molten mass with a solid crust as a result of its cooling. It was not until the 19th century that the first calculations of the age of the Earth based on its thermal evolution were drawn up, and the term geothermal was first defined as the scientific discipline that studies earth's heat, origin of this heat, distribution and use.

Precisely, the use of this thermal energy is what has led to the development of geothermal energy. Geothermal energy allows us to take advantage of the heat energy inside the Earth in different applications, using the laws of thermodynamics.

The Earth is a warm body immersed in a cold space…

Geothermal energy to generate electricity

Geothermal energy to generate electricity

Geothermal energy is that energy that can be obtained by man through the use of heat from the interior of the Earth. This type of energy has many applications. One of these applications is the generation of electric power.

The generation of electricity from geothermal energy is a good complement for hydroelectric plants, which also has the advantage that it is constant throughout the year.

Geothermal plant

Geothermal power plants are the plants responsible for converting geothermal energy into electricity. A geothermal plant is a facility where electricity is generated by geothermal energy.

Geothermal power plants are similar to other turbine thermoelectric power…

Electricity. What is it?

Electricity. What is it?

With the term electricity we refer generically to all physical phenomena in a macroscopic scale that involves one of the fundamental interactions, the electromagnetic force, with particular reference to electrostatics. At a microscopic level, these phenomena are due to the interaction between charged particles on a molecular scale: the protons in the nucleus of atoms or ionized molecules and the electrons. The typical macroscopic effects of such interactions are electric currents and the attraction or repulsion of electrical bodies or charges.

Electricity is the form of energy that produces light effects, mechanical, calorific, chemical, etc., and that is due to the separation or movement…

Zero law of thermodynamics

Zero law of thermodynamics

The zero law of thermodynamics speaks of what we experience every day: two systems that are in thermal equilibrium with a third are in equilibrium with each other. It is said that two bodies are in thermal equilibrium when, on contacting each other, their state variables do not change. Around this simple idea the zero law is established.

Every law of physics has its relevance, as well as the zero law of thermodynamics, which curiously was the last law to be introduced in literature. After the realization that heat is a form of energy that could be transformed into another, thermology was called thermodynamics. To obtain a logical structure in the presentation of thermodynamics, it…

Enthalpy What is it?

Enthalpy What is it?

Enthalpy is a term linked to the field of thermodynamics. The enthalpy symbol is H.

Enthalpy is also known as absolute enthalpy or amount of heat.

We define enthalpy as a physical quantity defined in the field of classical thermodynamics so that it measures the maximum energy of a thermodynamic system theoretically capable of being eliminated from it in the form of heat or thermal energy.

Enthalpy is particularly useful in the understanding and description of isobaric processes: the constant pressure, the enthalpy change are directly associated with the energy received by the system in the form of heat, these are easily measurable in calorimeters.

As defined, the…

Thermodynamic system

Thermodynamic system

A thermodynamic system is a portion of the material space, separated from the rest of the thermodynamic universe (that is, from the external environment) by means of a real or imaginary control surface (or edge), rigid or deformable.

A thermodynamic system can be the seat of internal transformations and exchanges of matter and / or energy with the external environment (that is, everything external to the system that interacts with it).

Classification of thermodynamic systems

Within thermodynamics there are three main types of thermodynamic systems: open, closed and isolated. In particular:

  • Open thermodynamic system. It is said that a system is open if it…

Geothermal. What is it?

Geothermal. What is it?

Geothermal energy is the discipline of Earth Sciences that studies the set of natural phenomena involved in the production and transfer of heat or thermal energy from within the Earth.

In a broad sense, the geothermal concept can also be extended to the study of other planets. Its principles are exploited at a technological level in the production of electricity and cogeneration through geothermal power plants from the associated geothermal energy.

The origin of earth's heat from a geothermal

The heat of the Earth's core was originally generated during the accretion of the developed planet thanks to the gravitational pull force. Subsequently, heat continued to be generated…

Hydraulic energy

Hydraulic energy

Hydraulic energy is an alternative and renewable energy source that 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. This mechanical energy can be used directly to rotate the shaft in some application or machine that works in hydraulic power. Anyway, the most usual thing is to use this kinetic energy to generate electrical energy. In this case, we talk about hydroelectric power.

In hydroelectric energy, the kinetic energy is finally transformed into electricity thanks to an alternator coupled to a turbine. This process is carried out in a hydroelectric…

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

Geothermal energy is usually 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 at a constant temperature throughout the seasons.

However, the use of geothermal energy implies some advantages and disadvantages that we analyze below.

Advantages of geothermal energy

Scale Fahrenheit

Scale Fahrenheit

The Fahrenheit degree (° F) is a temperature unit proposed by Gabriel Fahrenheit in 1724.

On the Fahrenheit scale, the melting point of water is 32 degrees of temperature, and the boiling point is 212 degrees. A difference of 1.8 degrees Fahrenheit equals that of 1 degree Celsius. Fahrenheit established the zero temperature (0 ° F), the freezing point of a 50% mixture of salt (ammonium chloride) and ice, and as 96 ° F, he took the temperature of the blood (he used that of the horses ). The figure 96 may seem an odd measure, but in principle the scale contained only twelve equal subdivisions, he himself divided each division into eight more, finally obtaining 96 divisions…
