…That’s a lot. It depends how much driving you do, how fast you go, etc.
Motors/engines get exponentially less efficient as you add more. So, if you can maintain a decent speed with less motors you definitely should, especially if you drive around a lot. You might even be able to maintain efficiency by just turning off the extras when you don’t need to go 250km/h.
A minifreezer uses a decent amount, but shouldn’t be too big of a worry, especially if you turn it off in winter.
The 3 floodlights is a bit of an issue. Have you considered atomic lamps for internal, side and rear lighting, then using standard headlights for the front? Generally speaking your turrets should handle anything that gets nearby, and you can’t drive sideways anyway. Forward headlights and MAYBE 2 rear floodlights should be more than enough if you get in trouble.
Cameras use very little, but you should still turn them off when not in use. Also keep in mind they have limited range compared to normal vision, so you might consider swapping to mirrors in some places.
To my knowledge turrets have no passive power draw, only a cost on firing.
