This class explores global greenhouse gas emissions from energy systems and potential levers for reducing emissions. Lectures and projects focus on decomposing contributions to greenhouse gas emissions, with a particular emphasis on technology related variables such as per unit cost and carbon intensity of energy. Student projects explore technological change pathways for realizing emissions reduction scenarios. Topics include comparisons of the mitigation potential of different energy technologies, empirical studies and models of technological change dynamics, and models for technology portfolio management.
