New Regulation Of Energy Self-Consumption In Spain

New Regulation Of Energy Self-Consumption In Spain

After the repeal of the "Sun Tax", a new regulation has been promoted for producers and self-consumers of photovoltaic solar energy. In this article we will review the keys of this new legislation and we will reveal what is the ideal light rate for self-consumers of photovoltaic solar energy. 

The rate of self-consumers

Many people mistakenly think that once the solar panels are installed, it is never necessary to be connected to the electricity grid. Nothing is further from the reality, since to make this possible it is necessary to have batteries that accumulate the energy generated during the day to be able to use it at night,…

Biofuels Uses

Biofuels Uses

Biomass and biofuels is a type of renewable energy that can be used for the generation of electricity and heat. There are different applications of biofuels. The production technology of these alternative fuels allows to create different products.

The problem of the convenience of feeding with alternative fuels to those that originate from fossil oil is that, in motor fuels, all states in the world impose high taxation. However, biofuels must be considered as non-renewable energy because the generation and recovery time of the fields is lower than the consumption time.

A component of biomass are solid biofuels, of which there is a wide variety of firewood, charcoal,…

Thermodynamic State

Thermodynamic State

A thermodynamic state is a set of values ​​of properties of a thermodynamic system that must be specified in order to reproduce the system. The individual parameters are known as state variables, state parameters or thermodynamic variables.

When a sufficient set of thermodynamic variables has been specified, the values ​​of all the other properties of the system are unambiguously defined. The number of values ​​needed to specify the state depends on the system, and is not always known.

Status functions

The state functions describe the momentary condition of a thermodynamic system. Regardless of the path that the system follows to go from one…

Solar Accumulator

Solar Accumulator

A solar accumulator is a device that allows to store the solar energy captured by the solar panels. The objective of the compilers is to take advantage of the energy obtained at the time when solar energy can not be produced (during the night, cloudy days, etc.)

For this we distinguish two types of solar compulators:

  • Thermal solar compulators.
  • Electric solar compulators.

Solar thermal compulators store heat. This type of acomulator is related to thermal energy installations. In these installations the solar collectors capture the energy of the solar radiation to heat a fluid. This heated fluid allows…

Global warming

Global warming

In climatology the term global warming indicates the change in the climate of the Earth developed in the twentieth century and still ongoing. This change is largely attributed to emissions into the Earth's atmosphere of increasing amounts of greenhouse gases, and other factors that the scientific community has been identified as attributable to human activity.

In the course of Earth's history, there have been several variations of climate that have led the planet to cross different eras of ice alternated with warmer periods called interglacial eras. These variations are mainly due to periodic changes in the orbital design of our planet, with disturbances due to the periodic…

Geothermal Plant

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 energy is the thermal energy contained inside the Earth. These facilities perform a thermodynamic exchange at a certain depth of the terrestrial layers to heat a fluid. This heat is used to generate electricity. Because the heat inside the Earth is inexhaustible, it can be said that this form of electricity generation is a source of renewable energy.

Geothermal power plants are similar to other steam turbine power plants. In all thermoelectric plants heat…

Thermodynamic cycles

Thermodynamic cycles

In thermodynamics, a thermodynamic cycle is a circuit of thermodynamic transformations performed on one or more intended devices. The objective of these transformations is to obtain work from two sources of heat at different temperatures, or conversely, to produce through the contribution of work the passage of heat from the source of lower temperature to higher temperature.

Obtaining work from two thermal sources at different temperatures is used to produce movement, for example, in thermal engines or alternators used in the generation of electrical energy. Performance is the main parameter that characterizes a thermodynamic cycle. The performance is defined as the…

Flat Plate Collector

Flat Plate Collector

The flat plate solar collector is a type of solar thermal panel whose objective is to transform solar radiation into thermal energy. This type of solar collector has a good cost / effectiveness ratio in moderate climates and adapts correctly to a large number of applications of solar thermal energy (heating of sanitary water, heating of swimming pools, support for heating, preheating industrial fluids , etc.).

We can distinguish two basic types of flat plate solar collectors, depending on the configuration of the absorber: the "grid type" parallel, in the vertical and horizontal versions and the "serpentine type" series. Basically, the difference between the two is:

Nuclear Energy

Nuclear Energy

Nuclear energy is the energy that is obtained from the division (nuclear fission) or from the union (nuclear fusion) of an atom. Despite the existence of a large number of applications related to nuclear energy (medicine, industry, transport, etc.), the main application of this technology is the generation of electrical energy.

Electricity of nuclear origin is generated in nuclear power plants. At present, all nuclear power plants operate through nuclear fission reactions. The nuclear fuel they use is usually uranium or plutonium (by an artificial process). Because uranium resources are not unlimited, nuclear energy is considered a non-renewable energy source.

Silicon

Silicon

What is silicon?

Silicon is a chemical element of atomic number 14 and symbol Si. This chemical element belongs to group IV A of the periodic table. JJ Berzelius 1824 isolated it by reduction with potassium of silicon tetrafluoride (SiF4).

The crystalline elemental silicon is grayish in color with a metallic luster, very hard, with very high melting and boiling points, and is an intrinsic semiconductor. The amorphous form of the element occurs in brown powders, conductive of electricity, which can be easily melted and vaporized.

Silicon is a component widely used in photovoltaic panels due to its semiconductor properties. This…

Geothermal

Geothermal

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 of 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…
