Then take it out of the very cheap solar power + batteries that people swear we have. An entire olympic village is being built, new, at considerable expense - the carbon excess on that construction alone is going to be immense and that's all diesel ICE vehicles. Instead of doing a stupid thing: seriously reducing the livability of the buildings in a way no one would really want, do the smart thing and build out the renewable capacity - with the bonus that you get to keep the renewable capacity afterwards. (of course in reality, France has load following nuclear reactors: they can absolutely throttle up a little more to accommodate increased night time load, and power grid smoothing measures can ensure air conditioning the buildings works well with this - i.e. using variable speed compressors)
