The economics of industrial production, the limitations of global energy supply, and the realities of environmental conservation are an enduring concern for all industries. Wherever you turn, there's another entreaty to save energy, reduce carbon emissions and protect the environment for posterity. Nowadays all segments of society must be examined and revised to do more with less or at least with the same energy consumption. People all over the world, especially in developed and developing countries, are invited to conserve energy resources not only to give a chance to other pre-developing countries and future generations to grow and prosper but also to preserve the environment. This book presents and discusses research in energy efficiency optimisation, as well as the reasons why this conservation of energy is needed on a global scale.
