This is related to provide a cost effective technology so as to meet the growing demands of various levels of consumers. Almost every product at some or the other stages during its manufacture or sale require the use of electricity.
To meet these demands enhancements in the methods of electricity generation are being implemented keeping the merits and de-merits of the technology in terms of environmental concern. To reduce the damages caused to the environment the conservation of energy becomes important. Changing trends emphasise on using renewable, sustainable energy sources, an alternative to fossil fuels, the use of low or no carbon technologies to reduce the environmental hazards (the IET Energy principles, www.theit.org/factfiles). There are basically two main sources to derive electricity-
A fissionable material like Uranium is used to generate heat in the core of the reactor. This heat is passed away by a coolant liquid or gas, which is then used to generate steam. The fission reaction emits neutrons, controlled by a set of rods made of a material capable of absorbing neutrons. Lowering this rod can shut down the reactor in emergencies. To protect the operators "biological shield", consisting of concrete several metres thick, surrounds the powerful radioactive reactor.

Gas provides 39% of electricity and 70% heat at homes in UK ...
