Lecture 11 introduces the material covered in Chapter 14 of Energy Systems and Sustainability, 2/e (2012), Remedies: towards a sustainable energy future. To this point this course has focused on the history of human energy use, technological innovation, and our move to and dependence on fossil fuels. The last lecture covers the 20th century's last conventional energy technology, nuclear power.
This lecture summarizes the problems caused by human energy use and looks at potential technologies and behaviors that can provide us with the abundant and inexpensive energy we've become accustomed to without the immense environmental and climate effects caused by conventional energy systems.
