Introduction to Energy and Earth Sciences is an introduction to microeconomic fundamentals with a focus on the applications of economics to energy and environmental markets. We will introduce the economic method of analysis to the environmental and resource questions facing society. We will learn about the market forces, supply and demand and how they are formed from two concepts of law of Diminishing Returns and Diminishing Marginal Utility. We extend our knowledge by exploring factors such as market dynamics and market equilibrium, government intervention and market power. At the end we will apply these concepts to real life examples and address Climate Change and Carbon Policy, Resource Scarcity and Energy Security, and Changes in the Electricity Business.
