Dr Sarah Darby:
Good afternoon. I work at the Environmental Change Institute at the University of Oxford, where at the moment I am the acting leader of the energy programme. Our work has, over the past 25 years, centred on energy demand and efficiency and, as time has gone on, it has broadened out into distributed energy generally. All demand is distributed, and increasingly a lot of supply is distributed, so we are getting more and more interested in smart grids. I should also perhaps say that I was lead on the synthesis report that was done for the Department of Energy and Climate Change on the early roll-out of smart metering.
