Rosemary will talk about her work at TNEI, a consultancy for the energy sector, and explain how maths is crucial to her work, whether that is predicting when the electricity cables running to your house will need replacing or figuring out how many wind turbines can you build at your wind farm without damaging the power lines it's connected to. This all involves lots of maths: modelling relationships between the weather and wind power, how much electricity people use, when electric cars are charged and much more!
