Most people do not buy from specific sources of production. They buy “from the grid”, the constituents of which are a dynamic mix of production sources (solar, wind, hydro, nuclear and fossile where I live). Wind is strong at night when solar produces nothing. Same in the winter months. As I said: if the power consumer is grid connected, this does not matter. Example: I have power in the socket even at night time :) As long as you have uninterrupted power (i.e. as long as connected to the grid), the important metric is mean cost of energy, not capacity factor of the production plant. For a nuclear sub or a space ship, which is not grid connected, capacity factor is very important. But data centers are usually grid connected. > when data enters need power all day every day nuclear is the only solution Do you think data centers running at night are running exclusively on nuclear-generated power :)? We already have lots of data centers that need power all day every day. Most are just grid connected. It works.
