SOURCES OF ELECTRICAL POWER SUPPLY
Introduction
Energy may be needed as heat, as light, as motive power etc. The present-day advancement in science and
technology has made it possible to convert electrical energy into any desired form. This has given electrical
energy a place of pride in the modern world. The survival of industrial undertakings and our social
structures depends primarily upon low cost and uninterrupted supply of electrical energy. In fact, the
advancement of a country is measured in terms of per capita consumption of electrical energy. Electrical
energy is superior to all other forms of energy due to the following reasons:
(i) Convenient form: Electrical energy is a very convenient form of energy. It can be easily converted
into other forms of energy. For example, if we want to convert electrical energy into heat, the only
thing to be done is to pass electrical current through a wire of high resistance e.g., a heater.
Similarly, electrical energy can be converted into light (e.g. electric bulb), mechanical energy (e.g.
electric motors) etc.
(ii) Easy control: The electrically operated machines have simple and convenient starting, control and
operation. For instance, an electric motor can be started or stopped by turning on or off a switch.
Similarly, with simple arrangements, the speed of electric motors can be easily varied over the
desired range.
(iii) Greater flexibility: One important reason for preferring electrical energy is the flexibility that it
offers. It can be easily transported from one place to another with the help of conductors.
(iv) Cheapness: Electrical energy is much cheaper than other forms of energy. Thus it is overall
economical to use this form of energy for domestic, commercial and industrial purposes.
(v) Cleanliness: Electrical energy is not associated with smoke, fumes or poisonous gases. Therefore,
its use ensures cleanliness and healthy conditions.
(vi) High transmission efficiency: The consumers of electrical energy are generally situated quite
away from the centres of its production. The electrical energy can be transmitted conveniently and
efficiently from the centres of generation to the consumers with the help of overhead conductors
known as transmission line
