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.

Dr. Rahul GoyalDr. Rahul Goyal is presently working as a Professor and Head of the Department of Mechanical Engineering at Manipal University Jaipur, India. He graduated in Mechanical Engineering from the University of Rajasthan and completed his masters from University College of Engineering, Kota in Thermal Engineering. He then pursued his Ph.D. degree from MNIT, Jaipur. His major research interests include alternative fuels in an IC engine, Waste heat recovery technology, Thermal energy storage, Combustion, Renewable Energy, etc. He has published more than 50 research publications in international peer-reviewed journals, reputed conferences, and book chapters. He also serves as a reviewer in various reputable journals. He has to his credit Invited Talks& Keynote addresses and chaired/co-chaired sessions at various conferences. He is a regular reviewer of research articles for many high-impact journals. He has supervised 3 PhDs and currently 3 research scholars are under his supervision. He is a life member of ISTE, India.
Dr. Satyanarayan PatelDr. Patel is currently working as a full-time assistant professor in mechanical engineering at the Indian Institute of Technology (IIT) Indore, India. He supervises Ph.D., master, and undergraduate students; and implements a research project funded by Science and Engineering Research Board (SERB) India. Previously, he worked as a prestigious Alexander Von Humboldt Post-doctoral Fellow in the Nonmetallic-Inorganic Materials Research Group, Technische Universität Darmstadt, Germany. His research focuses on bulk lead-free ceramics (piezoelectric and ferroelectric) for energy storage, conversion, and caloric effects for solid-state refrigeration. He first demonstrated the elastocaloric and barocaloric effect in bulk ferroelectric ceramics using indirect measurements for solid-state refrigeration. He also explored an unforeseen component of the electric field-drivencaloric effect termed the inverse piezocaloric effect. Additionally, he performed work on the effect of compressive pre-stressed (mechanical confinement) for tuning ferroelectric/pyroelectric/-piezoelectric properties for energy storage/conversion and other device applications. The current research is focused on pyroelectric energy harvesting and the flexocaloric effect in ferroelectric materials.
