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 natural resource limited. The generation of coal is a process of several million years, while the consumption of this energy resource is very fast. For this reason, coal is considered a non-renewable source of energy.
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…
Fossil fuels are often spoken of as a type of negative, polluting energy, harmful to the environment. Fossil fuels are considered a non-renewable energy source due to the difficulty of regeneration.
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.)
The theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust for millions of years was first introduced…
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…
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…
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…
For the conversion of fossil energy into electrical energy, the technology of a thermal power plant is often used. At the moment in which a thermal power station is fossil fuels fossilized from a source of non-renewable energy generation.
A thermal power plant (or thermoelectric plant) is a plant that generates electricity by transforming heat. Historically heat energy is converted into electricity by transferring heat to a working fluid and then transforming the energy of this fluid into mechanical energy. Finally, mechanical energy is transformed into electricity. The…
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:…
Biomass energy is biological energy, and allows biological entities (living beings) to move, to have brain activity and food production and the synthesis of biological tissues.
Biomass energy is continuously retransformed cyclically. The typical bioenergetic cycle of plants is called the "Calvin cycle". The bioenergetic cycle of living beings is called the "Krebs cycle". In these cycles the transformation of sugars occurs in other carbohydrates, the purpose of this transformation is the synthesis of very high energy concentration molecules, such as ATP and ADP. Technological…
