Energy Security: Economics, Politics, Strategies, and by Carlos Pascual,Jonathan Elkind PDF

By Carlos Pascual,Jonathan Elkind

Energy safeguard has turn into a most sensible precedence factor for the us and international locations world wide, yet what does the time period "energy safeguard" particularly suggest? for plenty of it really is assuring the secure provide and delivery of strength as a question of nationwide defense. For others it's constructing and relocating towards sustainable and low-carbon strength resources to prevent environmental disaster, whereas nonetheless others prioritize affordability and abundance of provide. The call for for strength has ramifications in every thing of the globe—from turning out to be call for in Asia, to the pursuit of reserves in Latin the United States and Africa, to the elevated clout of energy-producing states similar to Russia and Iran. but the very fact continues to be that the majority of worldwide power creation nonetheless comes from fossil fuels, and it'll take an intensive knowing of the interrelationships of advanced challenges—finite offer, environmental issues, political and spiritual clash, and fiscal volatility—to advance rules that would bring about real power safety. In E nergy Security, Brookings students current a pragmatic, cross-disciplinary examine the yank and worldwide quests for strength safety in the context of those geopolitical, monetary, and environmental demanding situations. for instance, political analysts Pietro Nivola and Erin Carter wrap their palms round simply what's capacity to be "energy self sustaining" and even if that's an a good suggestion or perhaps possible target. Suzanne Maloney addresses "Energy safeguard within the Persian Gulf: possibilities and Challenges," whereas economist Jason Bordoff and effort analyst Bryan Mignone hint the hyperlinks among weather regulations and energy-access regulations. Carlos Pascual and his colleagues research tender geopolitical concerns. Assuring long term strength safeguard is still one of many industrialized world's so much urgent priorities, yet steps in that path were debatable and infrequently risky, and effects so far were tenuous. during this insightful quantity, Brookings assesses precisely what we are speaking approximately, what it capability in numerous contexts, and the place we cross from here.
