Global warming reveals that the current evolution of the world consumption is on an unsustainable path. Humankind's insatiable appetite for energy has sparked a new crisis. In a world where climate change has become a proven reality, there lies a deep uncertainty about the physical, economic and social impacts of this phenomenon. The New Energy Crisis examines the impact of climate change issues into energy economics and geopolitics. Climate is a public resource that needs to be universally managed. The world economy has become global, but the world geopolitics has not. Nations are still here, defending their wealth, their local interests and their ambitions. This book follows a regional approach to improve our understanding of the dynamics of a multi-power world. Each region has its own specifications in terms of resource endowment, history and sensitivity to climate change. For millions of people economics growth is a priority, meaning increased energy consumption. The recent energy crisis exacerbates economic and geopolitical tensions. This book offers a concise view of what is in store for our future, and proposes that the real challenge of the century is to reinforce world governance to overcome this crisis. Solidarity between nations, people, and generations is the key.
