Photovoltaic power plant

A photovoltaic power plant is a set of facilities designed to supply electricity to the grid through the use of large-scale photovoltaic systems. The function of the photovoltaic power station is to capture and transform solar radiation into electricity.

A photovoltaic power plant is a power plant consisting basically of photovoltaic modules and an inverter. The photovoltaic panels are in charge of transforming the solar radiation, into electrical energy of direct current. The inverter is the electronic equipment whose function is to convert the DC power produced by the photovoltaic…

Power inverter

An inverter is an electronic device. The function of the inverter is to change a DC input voltage to a symmetrical AC output voltage, with the magnitude and frequency desired by the user. The inverters use in a great variety of applications, from small power supplies for computers, to industrial applications to control high power. The inverters are also used to convert the direct current generated by photovoltaic solar panels, accumulators or batteries, etc., into alternating current and thus be able to be injected into the electrical network or used in isolated electrical installations.

Entropy - Thermodynamics

Entropy - Thermodynamics

What is entropy? Entropy (S) is a thermodynamic quantity originally defined as a criterion for predicting the evolution of thermodynamic systems.

Entropy is a function of extensive character state. The value of entropy, in an isolated system, grows in the course of a process that occurs naturally. Entropy describes how a thermodynamic system is irreversible.

The meaning of entropy is evolution or transformation. The word entropy comes from the Greek.

Entropy in the world of physics

In physics, entropy is the thermodynamic magnitude that allows us to calculate the…

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…

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.

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…

First Law of Thermodynamics

First Law of Thermodynamics

The first law of thermodynamics was announced by Julius Robert von Mayer in 1841. It is the principle of conservation of energy.

Definition of the first law of thermodynamics: The total energy of an isolated system is neither created nor destroyed, it remains constant. Energy only transforms from one type to another. When one energy class disappears, an equivalent quantity of another class must be produced.

A body can have a certain speed with what has kinetic energy. If it loses speed, this kinetic energy that it loses becomes another type of energy, whether it is potential energy…

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…
