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,…

Generations of biofuels

Generations of biofuels

The generation of biofuels, a priori, represents several advantages with respect to obtaining fossil fuels used to obtain fossil energy. The main advantage is that the regeneration of resources is not millions of years as it happens with coal, oil or natural gas. Anyway, the regeneration of biofuels is not fast enough to be considered a renewable energy source either. They are considered, then, a non-renewable source of energy.

On the other hand, biofuels continue to be an indirect way of harnessing solar energy. In this case, solar energy is exploited thanks to the photosynthesis of…

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).

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…

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…

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.

What is fossil energy?

What is fossil energy?

Fossil energy is the energy that comes from the combustion of fossil fuels.

It is a source of non-renewable energy because it is not an inexhaustible energy source nor regenerates at the same rate at which it is consumed.

Fossil fuels are formed from organic substances that have accumulated in the ground. These substances can be the remains of plants, animals and other living things. Over the years, millions of years, they undergo certain physical and chemical transformations until they reach the point where they become components of which it is easy to convert them into energy:…

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…

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…

Nuclear energy

Nuclear energy

Nuclear energy is the energy obtained from the division (nuclear fission) or union (nuclear fusion) of an atom.

Despite the existence of large numbers of nuclear energy related (medicine, industry, transport, etc.) applications, the main application of this technology is the generation of electricity.

Nuclear power plants

Currently all nuclear power plants use nuclear fission to operate. Nuclear fusion is a technology that has many advantages but is not yet in a position for it to be used mainly for technical reasons.

Nuclear power plants are responsible for transforming…

Petroleum

Petroleum

Oil is a complex non-homogeneous mixture of hydrocarbons, composed / formed by hydrogen and carbon. The oils are very different from each other, can be from yellow and liquid to black and viscous. These differences are due to the relationships between the types of hydrocarbons. It is a non-renewable natural resource, raw material for numerous materials and products and, as a fossil fuel, the main primary energy source in the world.

The chemical components of petroleum are separated and obtained by distillation through a refinery process. From it different products are extracted, among…
