Energy is the hottest topic of concern in the world today. Fast receding stocks of conventional resources impelled governments worldwide to include renewable energy sources in their energy programmes. Newer, non-conventional methods need to be developed before the conventional stocks are totally exhausted. More and more universities in India are including the studies on renewable, non-conventional resources in their curricula in the 4th year of their BE/BTech (Mechanical) programmes. This book caters to such courses as a full-fledged textbook. It covers a wide range of topics from the origin of all energy sources, their manifestation, availability, resource assessment to science and technology of renewable energy conversion processes. Every chapter enunciates its learning objectives before beginning the discussion and offers insightful questions in the end. Renewable energy is going to be a very important part of the whole energy chain and its know-how will be essential at various levels of education, especially in science and engineering. Considering this fact, this book will also serve as a knowledge compendium for the seekers in renewal energy sources and technology.

First Edition 2012; Reprints 2013, Second Revised Edition 2014 I. The Textbook entitled "Non- Conventional Energy Sources and Utilisation" has been written especially for the courses of B.E./B. Tech. for all Technical Universities of India. II. It deals exhaustively and symmetrically various topics on "Non -Conventional Renewable and Conventional Energy and Systems." III.. Salient Features of the book: • Subject matter has been prepared in lucid, direct and easily understandable style. • Simple diagrams and worked out examples have been given wherever necessary. • At the end of each chapter, Highlights, Theoretical Questions, Unsolved examples have been added to make this treatise a complete comprehensive book on the subject. In this edition, the book has been thoroughly revised and a new Section on "SHORT ANSWER QUESTIONS" has been added to make the book still more useful to the students.

There has been an enormous increase in the demand for energy as a result of industrial development and population growth. Due to the depletion of fossil fuels at a rapid pace, harnessing the power of clean, alternative energy resources has become a necessity. Thus, the book aims to increase awareness among readers about the renewable energy resources and the technologies used to harness them. Written in a lucid and precise manner, the text matter is structured in the question–answer format supported with numerous examples and illustrations. Besides discussing various renewable energy sources such as solar, wind, biogas, hydrogen, thermoelectric, tidal, geothermal, wave and thermal, the book also discusses energy management and environment and outlines Kyoto Protocol. The book caters to the needs of undergraduate engineering students of all branches.

With energy sustainability at the forefront of public discussion worldwide, there is a vital requirement to foster an understanding of safe alternative sources of energy such as solar and wind power. Tailored to the requirements of undergraduate students of engineering, Non-conventional Energy Resources provides a comprehensive coverage of the basic principles, working and utilization of all key renewable power sources—solar, wind, hydel, biomass, hyower and fuel cells. The book also consists of several solved and unsolved questions for thorough practice and revision.

In the years between the first and this second edition, renewable energy has come of age; it makes good sense, good government and good business. This book considers the unchanging principles of renewable energy technologies alongside modern application and case studies. In this second edition, the presentation of the fundamentals has been improved throughout, and chapters on economics and institutional factors have been added. Likewise, sections on environmental impact have been added to each technology chapter. Renewable Energy Resources supports multi-disciplinary.
