This book gathers the proceedings of the Energy and Sustainability 2018 Symposium (EAS 2018) held in Windsor, Canada in June 2018. It brings together the state-of-the-art on specific aspects of the current energy status, and covers a wide range of energy and engineering systems, from internal combustion engines to electric vehicles, from the atmosphere, solar and wind, to underground geothermal and underwater turbines and energy storage. The book demonstrates how conventional internal combustion engines have advanced dramatically in terms of both performance and emissions over the past century. It also studies how life-supporting elements, such as water and greenhouses, must be prioritized and protected to ensure a sustainable future. The book offers a valuable source of information for future leaders, engineers, environmentalists, social forerunners, and decision-makers alike. It also provides a reference guide for both undergraduate and graduate students in engineering, the natural and social sciences, business and economics.
