INTRODUCTION.
- The electrical energy has become an indispensable part of our lives, is inconceivable level of development without the continued presence of the same.
If we consider a short space of time we realize that everything around us is presented in the state that presents us with the intervention of electricity.
The following table shows the variation in electricity consumption has occurred in Spain in recent years:
is noted that electric power consumption in Spain during the period 1990 - 2005 have suffered a 121822 GWh total variation which is or increase the wattage kind that yields 94%.
If we consider the English GDP growth over the same period will see that the increase could be related to the increase in the electrical wattage kind that yields.
previous indications are made with a dual purpose:
a) Be aware of the importance of electric power development has of our societies.
b) lead us to the realization of a deep reflection on how to combine the following three factors: development sustainable electricity consumption and the environment. In the XXI century it is essential to properly organize the three factors above in order to contrubir to the rescue of our planet, to be able to diminish the greenhouse effect, climate change, etc.
Regardless of whether or not an electrical technician, if it would be appropriate that any educated person in today's society tiviese basic knowledge which involve energy transformations in order to increase their sensitivity to achieve the most efficient use possible electrical energy.

DEFINITION OF ELECTRICITY.
- Electricity is a form of expression the energy, energy being able to produce everything work.
There is a conversion of mechanical energy into electrical energy, electrical energy is obtained through the rotation (mechanical energy) of a loop (electrical conductor) within a magnetic field.
power is "pulled "to the electrical circuit through the brushes can thus feed a receiver (light) or a group of receivers.
In this case the transformation the reverse happens, we have an electric generator (battery) which supplies a brush through a loop causing the rotation of the same (mechanical energy) within it.
In the next slide down some types of energy transformations, sets out the two fundamental principles of thermodynamics.

DEFINITION OF ELECTRICITY (II)
- electricity or electric current is the movement of electrons from a negative charge to positive charge outside.
- The elementary circuit is constituted by:
- energy source.
- Receiver.
- opening and closing mechanism.
- wires.
