Dr Sarah Darby:
Potentially, this is part of a very big transformation of our energy system. If we are relying heavily on renewable supply, particularly for electricity, we have to be able to match demand with supply in real time very effectively. The smart meters are part of making that possible. That means effectively that they are part of the transition to a renewables-based energy system with very carefully managed demand and supply together. The environmental benefits of that would be very considerable.
