In light of the rapid fluctuations in oil prices and subsequent impact on the stability and economic perspectives of energy producing and energy importing states in the Western Hemisphere, this book stresses the urgency to integrate sustainability at the very core of national energy security strategies. From Canada to Argentina, this edited volume analyzes a series of case studies and diverging paradigms across the continent. It underlines how the relatively recent exploitation of unconventional energy sources in North America and the resulting impact on prices impact the geopolitical concerns of traditional producers. It also explains how much energy strategies are central to the development of national economies and the stability of their society. Highlighting the shortcomings in several countries even at a time of high prices, the volume makes the case for an inclusive and holistic approach to energy security that would integrate environmental concerns at its very core. This edited volume also explains how this new energy independence of the western Hemisphere affects its foreign policy with the main international actors in the field of energy whether traditional producers or consumers. Finally, it provides key insights on successful strategy towards the development of alternative sources of energy.
