Inventions of Electricity and Magnetism give a boon to human beings. A lot of electrical power generation systems have been developed with advanced features and applications. This book consists of all things regarding d.c. and a.c. electricity, resistors, inductors, capacitors, electrical circuit analysis, electricity transmission-distribution networks, d.c. & a.c. generators and motors, all conventional power plants like Thermal Electric Power Plant, Hydro Electric Power Plant, Nuclear Electric Power Plant, Biomass Electric Power Plant. Thereafter existing non-conventional or renewable electric power generation systems such as Solar, Rains, and Wind Electric Power Generation Systems are delineated. Further inventions on renewable electric power generation systems like Charged Cloud, Lightning and Thunder Electric Power Generation Systems are enlightened. In the forthcoming days these six renewable electric power sources like Solar, Rains, Wind, Charged Cloud, Lightning, Thunder energies can be integrated to emerge a reliable electric power source in all times.
