A secure supply of energy is essential for all nations, to sustain their economy, and indeed their very survival. This subject is especially important in the case of China, as China's booming economy and consequent demand for energy is affecting the whole world, and in turn potentially driving realignments in international relations. Moreover, as this book argues, energy security should be considered more broadly, to include issues of sustainability, environmental protection and the domestic organisation of energy policy and energy supply. This book presents a comprehensive picture of China's energy security. It covers all energy sectors - coal, oil, gas, renewables; international relations with all major sources of energy supply - the Middle East, Central Asia, Africa; and key areas of domestic policy making and supply.
