Use https://coriolis.io/ to figure out your power usage. It gives you a lovely chart on the bottom-right of the Power and Costs tab.
Apparently you are not running an updater. You should. EDDiscovery, EDDI and EDMC are commonly used tools. They also do lots of other things; the most lightweight variant for just uploading data is EDMC. They can also upload your stats, fleets, materials, discovered systems and whatnot to EDSM and Inara. Those are pretty handy sites, too.
EDDI
