Every individual, organisation, or society uses energy in some form or the other. Increase in world population, and consequent material consumption in both the developing and the developed hemispheres is leading to a phenomenal increase in world energy requirements. The challenge is not only to satisfy this huge energy need but also to look out for ways to secure affordable and sustainable energy.

The book starts with the basics of energy, greenhouse effect, energy scenario of India and the world at large. Then it broadly describes wide range of renewable energy technologies like wind, solar, hydro power, geothermal energy, and biomass. Finally, the book goes beyond renewable energy to the areas of sustainability, covering nuclear energy, clean coal technology, carbon capture and storage, and more importantly, energy efficiency in the building, transportation and smart grid. Besides describing relevant technologies of renewable and sustainable energy, various academic programmes in India and abroad in these areas, and huge career prospect in the emerging green field areas have been described.

The book is primarily intended for the discerning students who are looking for an exciting career in the niche field of renewable energy technologies. It will be a useful guide to enthusiasts who are interested in greening the world.
