In today's world, production, development and civilization need energy. Energy is the true power of countries, and the magnitude of its consumption serves as a good indicator for the development rate of nations. Both great and regional powers use this tool as a trump card to dominate the world and their influence areas. Energy rules the world and shapes each nation's policies. In addition, conflicts between countries arise during the race for energy domination. All of these developments make energy a special research topic today. As such, this book covers this subject from a multidimensional view, and includes examinations of many special energy zones like Russia, the Middle East, and the Caspian Basin, as well as the energy policies pursued by leading nations.
