I don’t know about a guide, but how about a mindset change. Wind turbine into a large battery. Large battery into the bottom of an electrical branch (the black one).
Put 10 electrical branches neatly side by side by holding shift (it snaps them). From the first electrical branch, top right to the bottom of the next one. Rinse and repeat that until all are connected.
Then the top left of all your electrical branches will go into your electrical things. Some have pass-throughs, some don’t. For example, you can connect a light to another light, but you can’t do this for turrets, so they need their own electrical branch.
Each item you craft will tell you how much power you need. For example, a hanging light is 2. If you hook 3 up, on that electrical branch, you need to change the number to 6. If you hook a turret up, it will say 10, so change the electrical branch to 10.
As you go along your electrical branches with a wire tool, it will tell you how much power you have left to play with after each thing.
I recommend leaving around 15 power untouched, seeing as wind can change in Rust and lower the power. The higher up your windmill, the better.
Also, with solar panels, each one when facing direct north, which is the best direction, will give you 20 power.
With batteries, I think the max power outputs are as follows:
Small battery: 15
Medium battery: 50
Large batter: 100
For example, you can only use 15 power on a small battery. What this means is you can use a turret and a fridge on a small battery, because a turret uses 10 power and a fridge uses 5. However, to make sure one of these things is getting constant power while using a small battery, I’d only hook the turret up, and because the turret is so important, I’d hook two solar panels up to a root combiner (the red one), just to make sure it always had charge in the battery, because weather conditions can change, impacting the power you get.
It’s simple really, and once you wrap your head around these simple things, the world is your oyster to do more complicated setups.
