and albert museum and see if there are any questions. and there's one over to my right there. thank you very much. jane sutton from the royal academy of engineering. just on your point about balancing demand, a few years ago there was a lot of chat about a european super grid to share renewable electricity, and we've even had a presentation from somebody who was looking at a global super grid. do you think that's possible? would it be helpful to balance demand in different parts of the world? i actually want to let danielle take that one. a global super grid sounds like your sort of scale with your quarter of a kilometre wind turbines. yes, thank you. what do you think? i'm so glad this question was asked because that's one of the — there's actually two components to the rollout of a significant scale of renewable energy that we haven't talked about. one is the ability to balance those demand changes over time and balance the geography and the weather patterns over space by connecting more of our regions together.
