The first thing to talk about electrical energy is to know what is the electrical energy at first then we talk about its details :)
so:
Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable interest in the late nineteenth century after commercialization of the electric telegraph and electrical power source. It now covers a very wide range of subtopics including power, electronics, control systems, signal processing and telecommunication.
Also we find that electrical engineering is interested in the basic forms of powers that run our world. Whether it's gas, Hydro turbines, Steam turbines, fuel cell, solar cells, geothermal, or wind turbine energy.
Electrical engineering may include electronic engineering. Where a singularity is made, usually outside of the United States, electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas electronic engineering deals with the study of small-scale electronic systems like computers and integrated circuits. Also we find that electrical engineers deals with distributing electric energy from its sources to our homes, factories, offices, hospitals, clubs and schools. While electronic engineers are interested in using electricity to process and transmit information, More recently, the distinction has become blurred by the growth of power electronics.
Finally to be honest ... this article is taken from another sites and combined so that it is more useful for you ... specially it is the summary of the many articles i found ... that is instead of entering many sites and you may find your target or not :)
see you all soon .. mohamed :)
