Book excerpt: This book will show that when some countries begin using oil and gas as an instrument of exerting pressure and to realize political goals, energy security becomes synonymous with national security as well as economic security.

This book highlights that the Nordic countries represent a very broad spectrum of competencies and techniques in the field of making use of various energy sources, which basically exhausts all the possible and currently available possibilities.
