Energy and the Earth (Coursera)

Taught by:

Learn how all energy systems depend on the finite resources of the Earth, and how this relationship can provide a unique “big picture” perspective on energy supply.

Energy consumption and its consequences have spurred some of the most important public debates of our time. We are presently confronted by an unprecedented paradox: the negative consequences of fossil fuel combustion have never been clearer, but oil and gas extraction are experiencing a technological revolution. How long with fossil fuel supplies last? What are the long-term implications of fracking and other technologies that extend their use? At what point will renewable energy systems replace fossil fuels altogether? Such questions have a direct impact on our health, wealth, and security, but reliable answers are scarce.

In this class we will develop a unique, “big picture” perspective on these issues, based on the concept that all energy systems, fossil and renewable, depend on finite geologic resources of the Earth. Armed with this perspective, energy consumers, producers, and policy makers can make more informed choices for the future. This course will emphasize three universal principles:

1. Energy quality matters more than quantity,

2. Technological advances continually redefine reality, and

3. All energy systems carry their own negative consequences.

We will explore energy options ranging from solar to nuclear, revealing how the above principles apply to each.
