Electric power. What is it?

Electric power. What is it?

We define electrical energy as the form of energy that results from the existence of a potential difference between two points. When these two points are brought into contact by an electric conductor we obtain an electric current.

Physical aspects of electrical energy

From the physical point of view, electrical energy is negative electric charges (electrons) that move through the electric conductor, usually metallic, due to the potential difference between its ends. The reason metal conductors are usually used is because they have more free electrons.

Electric charges moving…

Nuclear power in France

In 1974 the French government decided to rapidly expand production capacity of nuclear power in France just after the first oil crisis. This Decision n was made in the context of a France with substantial competition in engineering, but few indigenous energy resources. Nuclear power, with the cost of fuel is a relatively small the total cost, in this sense, getting a reduction in imports and greater energy security could.

As a result of the decision of 1974, France currently has a high level of energy independence and almost the lowest cost electricity in Europe. It also has a level…

Fukushima nuclear accident

Fukushima nuclear accident

On March 11, 2011 in Fukushima occurred one of the worst nuclear accidents in history after the Chernobyl nuclear accident.

A 8.9 magnitude earthquake off the northwest coast of Japan and a subsequent tsunami severely affected Dahiichi Fukushima nuclear plant on the northeast coast of Japan.

At the time of the nuclear accident at the Fukushima reactors had 6. Reactors 1, 2 and 3 were operating while nuclear reactors 4, 5 and 6 were unemployed for maintenance.

After the earthquake Fukushima reactors that were still running is automatically stopped. To cool the reactors,…

Renewable energy

Renewable energy

Renewable energies are those energies using an energy source or fuel which is considered inexhaustible or can be regenerated at the same rate at which it is consumed.

The classification of renewable energy depends on natural resources exploited.

Solar energy

We distinguish two ways of using solar energy:

  • Solar thermal
  • Solar photovoltaics

The use of solar thermal is to use heat energy obtained from solar radiation to heat a fluid, depending on its temperature,…

Vandellos-2 nuclear power plant, Spain

The nuclear power plant is located on the Mediterranean Sea, in the town of Vandellos II, in the province Tarragona. National participation in the construction and supply of equipment accounted for more than 89% of the total, which represented the highest percentage achieved in Spain for such projects.

The whole plant, which has a pressurized water reactor consists of several main buildings: the containment building, fuel and auxiliary turbine building. It is also equipped with a water intake pipe cooling of the plant, consisting of reinforced concrete caissons, which juts out into the…

What is an electric generator?

What is an electric generator?

An electric generator is a machine able to transform any type of energy, which can be chemical, mechanical or light, into electricity.

An electrical generator is all that a device capable of maintaining electric potential difference (voltage) between two points, called centers or terminals. Electric power generators are machines designed to transform mechanical energy into electricity.

Operation of an electric generator

The operation of an electric generator is similar to an electric motor running in reverse.

This transformation is achieved by the action of a magnetic…

Nuclear power in Argentina

Electricity consumption in Argentina has grown strongly since 1990. Per capita consumption was just over 2,000 kWh / year in 2002 and increased to over 2,600 kWh / year in 2007. Gross production of electricity in 2007 was 115 million kWh, 54% from gas, 27% hydro, 9.4% oil, a 2.2% from coal, and 6.3% (7.2 million kWh) of nuclear origin. In 2008, nuclear energy provides more than 6.8 million kWh of electricity - about 6.2% of total electricity generation.

In Argentina, the electricity production is largely privatized, and is regulated by the ENRE (National Regulatory Authority for Electricity).…

Nuclear power in Mexico

Mexico is rich in hydrocarbon resources and is a net exporter of energy. Country's interest in nuclear energy is based on the need to reduce their dependence on these sources of energy. In recent years, Mexico's energy is increasingly dependent on natural gas.

The energy growth was very rapid in the 1990s, but then stabilized for a few years. Since 2007 expected new growth in demand for electricity to an average rate of almost 6% per year. In 2007, we generated 257 million kWh. Supply Origin is varied electric, gas 126 TWh (49%), oil of 52 TWh (20%), coal 32 TWh (12.5%) and hydroelectric…

Nuclear Moratorium

The nuclear moratorium supposed blocking 5 projects of nuclear power plants that had approved the 7 (and some insiders) in Spain.

The National Energy Plans and Nuclear Moratorium

In 1983 he drafted a National Energy Plan in qual nuclear energy in Spain was hit hard.

To bring national electricity production to energy demand and adjust prices of the Congreos Diputoado in June 1984 approved the 1983 National Energy Plan (PEN-83).

The nuclear stop was the main novelty of the PEN-83 that was slowing building program of nuclear power.

What reasons provoaron the…

Advantages and disadvantages of nuclear power

In this section we analyze the advantages and disadvantages of nuclear power. Nevertheless, most organizations related to nuclear energy are already positioned for or against the use of nuclear power. On this site we try to make an objective analysis about this question, giving all the relevant information and offering a space for different conclusions.

Advantages of nuclear power

The generation of electricity through nuclear energy reduces the amount of energy generated from fossil fuels (coal and oil). Less use of fossil fuels means lowering…

Nuclear Power Plant - What is it?

Nuclear Power Plant - What is it?

A nuclear power plant is a facility for obtaining electrical energy using nuclear energy.

Its operation is similar to that of a thermal power plant or that of a solar thermal plant: from a source of energy thermodynamics is used to obtain heat, with the heat to get steam and with the steam to drive a turbine that will generate electricity.

The difference between the different types of electrical installations is in the energy source: a nuclear power plant uses the heat released in the nuclear fission reactions of certain atoms, in a thermal power station the heat source (thermal…
