If I have three different energy usage and I want to display a total from all three, how can I do that?

Would I also be able to see a history of that calculated value?

I would recommend doing this by creating a Helper entity to "Combine the result of several sensors": https://www.home-assistant.io/integrations/min_max

Home Assistant

Min/Max

Instructions on how to integrate min/max sensors into Home Assistant.

(the integration is called "min_max", but it can also do a sum operation to get a total from multiple sensors)

that gives you a separate entity that you can add to a dashboard, and it will also have history/statistics tracked.
