This book is an up-to-date primer covering the most important subjects in energy economics, with particular attention paid to oil, natural gas, and nuclear energy, and without an excessive amount of mathematics. The first three survey chapters constitute an introductory (and mostly non-technical) short course in modern energy economics. Most of the technical analysis is taken up in the following four chapters, while the last chapter is a completely non-technical summation that can be read independent of the rest of the book. Written in a user-friendly tone, it is suitable as a textbook for undergraduate and/or graduate students, but most of the book should be accessible to anyone with a serious interest in energy economics.
