Natural gas

Natural gas

Natural gas is a source of fossil energy, like coal or oil, it is constituted by a mixture of hydrocarbons, molecules formed by carbon and hydrogen atoms. Its calorific value varies greatly according to its composition, but the highest are between 8,500 and 10,200 kilocalories per cubic meter of natural gas.

Natural gas is a primary energy, or that can be obtained directly without transformation. The other primary energies are solar energy, coal and oil. It is the cleanest fossil energy in terms of waste and atmospheric emissions, and the most efficient fuel for obtaining electricity…

Greenhouse effect

Greenhouse effect

The greenhouse effect is the process by which the atmosphere of a planet passes solar radiation from the Sun, but instead prevents or hinders the thermal energy output of the planet.

It is called greenhouse effect due to the similarity with the operation of the greenhouses that are able to retain the heat inside. The operation is not exactly the same, but it is very similar. The difference is that the greenhouse uses the glass and not the gases in the atmosphere to retain heat. That is why this natural phenomenon has been called the greenhouse effect.

When we talk about the greenhouse…

Fracking

Fracking

Hydraulic fracturing or geotechnical fracking is the exploitation of the pressure of a fluid, typically water, to create and then propagate a fracture in a layer of rock in the subsoil. Fracking is carried out after a drilling in a rock formation containing hydrocarbons (oil or natural gas). The objective is to increase the permeability. Improving permeability improves the production of oil or gas contained in the subsoil and increases its recovery rate.

Hydraulic fractures in rocks can be both natural and created by humans; they are created and enlarged by the pressure of the fluid…

Fracking. What is it?

Fracking, or hydraulic fracture, is an Anglo-Saxon term that is used to refer to a technique to increase the extraction of fossil fuels natural gas and oil from soil.

Carbon

Carbon

Coal is a fossil fuel that is used to obtain fossil energy through its combustion. The thermodynamic properties of coal allow obtaining a large amount of heat energy during its combustion process.

Coal is a sedimentary rock of organic origin, black or dark brown. It is used mainly as a fossil fuel because of its high calorific value because it has a majority carbon content. Coals can be classified by the percentage of carbon they contain, which is related to the percentage of moisture and impurities. According to this criterion, peat, lignite, coal and anthracite can be distinguished.

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…

Thermosyphon solar systems

These equipments have a natural circulation based on convection currents formed in the fluid at different temperatures.

If we heat a water tank at the bottom when the bottom water warms, it becomes less dense and rises to the surface where it cools. Then returns to the bottom of the container and thus a natural circulation flow is generated.

This is the operating principle of a thermosiphon team, which will be essential that:

  • The solar collector (heat sources) is always located below the level of the accumulator.
  • The primary circuit is as short as possible…

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…

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…

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…

Fossil fuels

Fossil fuels

Fossil fuels are often referred to as a type of negative, polluting, environmentally damaging energy.

Currently, fossil fuels are the most widely used energy source in the world. It is used to generate electrical energy but above all it is also used to generate mechanical energy (cars, heat engines, etc.).

What are fossil fuels?

Fossil fuels are those fuels that come from a process of partial decomposition of organic matter.

Fossil fuels originate from a transformation process of millions of years of plants and vegetables (cases of oil, coal and natural gas).

Passive solar energy

Passive solar energy

In the design of passive solar buildings, windows, walls and floors are made to collect, store and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because it does not involve the use of mechanical and electrical devices.

The key to designing a passive solar building is to make the most of the local climate by performing a precise site analysis. The elements to be considered include the placement and size of the window, and the type of glazing, thermal insulation, thermal mass and shading. Passive solar…
