O autorze

My academic career began in January 1992 when I joined the University of Victoria as a faculty member after obtaining Masters and Ph.D. degree from Northwestern University, Evanston, Illinois, U.S.A. in 1986 and 1989, respectively and spending the next couple of years at the University of Waterloo, Canada as a postdoctoral fellow and research assistant professor. In 1997 I moved back to the University of Waterloo as a faculty member until now.

My research group and I myself are currently focused on promoting/developing green (or greener) energy through energy diversification and energy localization for sustainable development and energy security. Green energy, despite the variety of interpretations possible, is taken as the form and utilization of energy with no, minimal, or reduced negative environmental and societal impact, or simply as environmentally friendly energy use. Therefore, the topical areas of my research activities and interests include, but are not limited to

The Progress in Green Energy series explores the evolution of green energy systems for sustainable development and energy security. It focuses on the development of new technologies which enable the provision of energy with minimal negative effects on society and the environment. Progress in Green Energy is a monograph series, which aims to provide up-to-date information for researchers, engineers, and advanced students.

The dominance or monopoly of a single energy system can provide a cumulative impact on a particular aspect of the environment, leading eventually to permanent damage or even catastrophe. Green Energy: Basic Concepts and Fundamentals addresses the need for diversity within energy systems. Although every energy system, including renewables and alternative fuels, has its own unique adverse impact, the impact need not be additive and cumulative. By using a diverse range of energy systems which exploit local energy resources, the energy need can be met without any negative impact beyond the tolerance limit of the environment. Additionally, energy diversity can withstand the fluctuations and disturbances in energy need, benefiting social and economic health in the process.

Green Energy: Basic Concepts and Fundamentals focuses on the theme of energy diversity with local resources, and the integration and optimisation of conventional and alternative energy systems. The book provides a summary of the state-of-art knowledge and technology for future energy systems, covering topics such as:

• green energy carriers;

• emission control, reduction, and abatement;

• energy conversation and management; and

• energy environment interaction.

This first book in the Progress in Green Energy series will be of value to energy researchers, technology developers and professionals from policy makers to engineers, as well as to advanced undergraduate and postgraduates studying in the field.
