This book reveals key challenges to ensuring the secure and sustainable production and use of energy resources and provides corresponding solutions. This book covers the advanced technologies applied in renewable energy generation, energy storage, an alternative to petroleum fuels, waste to energy, solar energy, the impact of fossil fuel combustion on the environment, green buildings, social sustainability, etc. It goes beyond theory and describes practical challenges and solutions associated with energy and sustainability. This book is of particular interest to graduate students and academic or industrial researchers/professionals working in renewable energy, sustainability, bioenergy, and mechanical and automobile engineering. This book makes a forceful foundation for the establishment of the role of renewable energy in energy transition for a sustainable, cleaner, and greener future. This book is unique compared to other available books because it covers a wide variety of topics on a single platform.

In this book, an attempt has been made to utilize waste heat from condenser of the refrigerator. This heat can be used for the number of domestic and industrial purposes. In minimum constructional, maintenance and running cost, this system is much useful for domestic purpose. It is a valuable alternative approach to improve overall efficiency and reuse the waste heat. The study has shown that such a system is technically feasible and economically viable. This system is nothing but a cabin that we are going to install over the head of the simple refrigerator, this cabin will be an arrangement of coils that will work as a heat exchanger. These coils are hot coils of the condenser of the refrigerator that will be modified and will braze in the cabin. It can serve the purpose of cooking (oven), geysers, etc. Besides, the refrigerator may be used as a conventional refrigerator by keeping the cabin door open in case of absence of heat sink. Further increase in COP is possible. ### Key Features- Graphs and figures for a better explanation.

This book contains the successful experiment on the application of radiant cooling using natural air for ventilation under the hot and humid climate of Rajasthan was studied. To avoid condensation of moisture on the cooling panel, the temperature of water supplied to the panel was limited to dew point temperature. Experiments were conducted in an experimental cabin during the hot and dry period in the month of March 2016. Results confirmed the good potential for application of radiant cooling. However, the room was served by radiant panels with a total area of (6 ×4) square feet. A special configuration was devised to achieve thermal comfort for the area served by the panel. ###Key Features- Figures and Graphs for better understanding.
