The ugly truth is that over 10% of the electricity in the generated in the US is wasted in converting power from the form in which it is delivered to the form necessary to be consumed. Power conversion is ubiquitous from laptop adapters to dataserver power supplies, Photovoltaic and hybrid car inverters to motor drives. Silicon has served the power function extremely well but has reached its materials limits. Wideband gap semiconductors are seen as the way that progress can be maintained and this tremendous loss in energy be reduced significantly. The impact is not only economic (over $40B in annual electricity savings), or environmental (equivalent of 300 coal fired power plants worth of energy) but critical for new systems architectures which, as in so many aspects of electronics, are determined primarily by thermal management. Low loss elements are also critical for determining the best hardware implementation of the final smart grid solution.
Umesh Mishra is a Professor in the ECE Department at UC Santa Barbara and leads the Gallium Nitride Electronics effort. He received his B.Tech degree in 1979 from IIT Kanpur, India (from where he is a Distinguished Alumnus). He received his M.S. from Lehigh University and his Ph.D. from Cornell University in 1984. He has received the IEEE David Sarnoff Award for "The Development of Gallium Nitride Electronics" and is an IEEE Fellow and a Member of the NAE.
