Efficiency and Decoupling: Part 1
This lecture by the instructor covers the concepts of environmental intensity, efficiency, and decoupling in the context of economic growth and sustainability. It explains how to measure efficiency, the relationship between activity and impact, and the difference between relative and absolute decoupling. Through examples, it illustrates how substitutions and improvements in efficiency can lead to reduced environmental impact. The lecture also discusses the importance of decoupling economic growth from resource consumption, showcasing real-world data on energy consumption and CO2 emissions in the power sector.
