Electric Power

Electrical energy is obtained by transforming "primary" forms of energy into mechanical energy, using machines such as steam and gas turbines, and combustion engines, etc. The mechanical energy produced is subsequently transformed into electricity through combining such machines with electricity generators.

Power is measured in Watts (W), while energy is measured in Watthours (Wh) which corresponds to the energy produced in an hour by a machine with a single Watt power.
The domestic consumption of electricity is measured in kiloWatthours (kWh) while for medium and large-size businesses, it is measured in MegaWatthours (MWh) and GigaWatthours (GWh).
 
The use of electricity is a characteristic feature of all sectors of activity in our society.

Electricity consumption continues to grow, as does the range of use.
