Every decision about energy involves its price, cost, and quantity. For economists, energy economics is one of three subdisciplines which, taken together, compose an economic approach to the development and preservation of natural resources and environmental quality. Energy economics, which focuses on energy-related subjects such as renewable energy, hydropower, nuclear power, and the political economy of energy Resource economics, which covers subjects in land and water use, such as mining, fisheries, agriculture, and forests Environmental economics, which takes a broader view of natural resources through economic concepts such as risk, valuation, regulation/policy, distribution with business application Although the three are closely related, they are not often presented as an integrated whole. This revised 3-volume set will bridge that gap by unifying these fields into a high-quality, comprehensive and unique overview. It will serve as an invaluable and unique tool to facilitate the first step in diving into a new subject within energy, resource or environmental economics. The chapters are written in a non-technical manner so that users outside of advanced academics or trained economists are also able to grasp the content easily. In addition, all chapters will follow a specific template throughout, thus providing a consistent and logical format for the reader.
