The global energy system and its future are central to understanding many of the key challenges faced by society today-from climate change to rising prices for commodities and Western interest instability in the Middle East. Unfortunately, today’s students are not well prepared to address these issues at their source. Few texts provide a broad overview of the science and policy challenges associated with the extensive array of energy resources that make up the current global energy system. Energy Resources takes a holistic approach to energy that covers both the science and social-science issues of today’s global energy system. It simplifies the scientific background of the resources, describing each step-from formation to transmission-to make the science accessible to students. Each resource is discussed in both the US and global contexts in order to analyze its impact on the environment, economy, society, and politics.
