Energy management and Conservation is the area which requires general awareness among the people. The motto is "Energy conserved is energy produced". The subject of Energy management which was in the curriculum of the graduate courses has slowly drifted into under graduate courses also. But unfortunately, there is no single textbook in this field catering to the needs of student community, energy managers/energy auditors and so on. Hence, an attempt is made to present essential, useful and practical principles of Electrical Energy Management. The principles of Economics needed to analyze the Economical Viability of the proposals for the Energy Conservation schemes are also dealt with examples in this book. Case studies presented in the book will definitely be useful to the students and the concerned professionals.
