Energy is a fundamental enabler of economy, and revolutionary changes in energy cost and effectiveness, from animal and wood, to coal, whale oil, petroleum and nuclear technologies, have deeply shaped throughout history societal evolution worldwide. The nextwave of changes, as the world economic engine integrates renewable energy technologies such as solar technologies or biofuels, perhaps constitutes a greater challenge since predictably these technologies will be at least transiently less efficient than the conventional energies of today based on fossil and nuclear fuels. Understanding these challenges that lie ahead is an important task to perform in order to design winning industrial strategies for the future. Chapter 1 and 2 discuss about the basics of biofuel andThe Global Demand for Biofuels: Technologies, Markets and Policies. If biofuel is one of the expected solutions, we must know where is the beginning of the crisis and its solution. This chapter reviews the background story along with an optimistic outlook for a safe energy resource on our green earth. Chapter 3 is based on the Renewable Energy Resources. Chapter 4 depicts about the biomass and biofuels. Chapter 5, 6, 7 and 8 covers the use of bioethanol, hydrogen, methane and methonal. Chapter 9 describes the use of Ethanol and Methonal as fuel. Chapter 10 is based on the Energy systems, their storage and transmission. Chapter 11 depicts the Institutional and economic factors from renewable. The association of the book is concocted to encourage viable learning encounters The book is organized in a manner to cater to the needs of students, researchers, managerial organizations, and readers at large. It is hoped that this book will help our readers to understand: What are the various biofuels available to us; Why biofuels are required; Howto use biofuels. What is the need to Conserve these biofuels.
