In their 2008 report, the National Academy of Engineering identified developing affordable solar energy as one of the Grand Challenges for Engineering in the 21st Century. Today, solar energy provides a small fraction of the electricity used in the US, but is poised to make increasing contributions to electrical energy consumption nationwide. Fleddermann looks at the current situation and describes the innovations that will help make solar energy affordable.

Charles (Chuck) Fleddermann is a professor of electrical engineering and associate dean of engineering at UNM. He has taught courses on professionalism and ethics in engineering at UNM as well as to the larger engineering community. His book, Engineering Ethics, is now in its fourth edition. Fleddermann received his PhD in electrical engineering from the University of Illinois at Urbana-Champaign.
