There has been long felt need for professional book written by an international author on energy demand. It is gratifying to note that this book will immensely contribute to the growth and development of various energy resources required to meet the energy demand of developing nations like Nigeria and other nations of the World. Energy planners, researchers, lecturers and students of higher institution are undoubtedly aware of the gap in information on energy demand in developing and third world countries. It is therefore the purpose of this book to provide the needed link. The book investigated energy policy short falls, their relevance to socio-economic development, probable energy demand and efficient use in developing Nations such as Nigeria. Each chapter of the book is quite revealing and incisive. With all these as a base, the book forecast energy requirement and used it to estimate the energy demand of Nigeria in the year 2022. The forging and many others formed the crucial viewpoint written in this edition. I therefore recommended the book to Energy planners, Researchers and more especially to students, academicians, policy makers and the general public at large.
