If you are running different sources of energy in your base, how does the game decide which source to draw from first? For example, I am currently using a big reactor with some solar power. Both end up connecting to the same energy conduit that powers all of my machines.

It could depend on the mod, but it's usually closest first.

Why are you caring about it anyways?

Because I do, why are you caring why I care?
Be mindful of ambiguous tones and intentions folks.

In this case, I'm personally interested in why you care because I may have a solution which dodges the problem in the first place.

As a possible answer (alluded above): It's probably, for all intents and purposes, random. The machines don't queue up one mod at a time afaik, so it'll be mostly first come first serve.

I work around this by ensuring I don't power my machines directly. I centralize my power supply (into an Energy Cell or Battery Buffer or Capacitor Bank, whatever floats your boat), and activate/deactivate my power sources as needed depending on the fullness of that supply.

To be perfectly blunt, I got snarky because he did.

The reason I care is because my big reactor requires ore and my solar does not and I would prefer my systems (I run a lot of IC2 stuff just because I like it=) to use the free energy before the one that costs me resources. My panels are always at zero energy saved which tells me 100% of the energy is being used, however, if it made a difference where the solar energy conduit connected in relationship to the machines, I would want to change my layout some.

This is ambiguous. I read it as a plain inquiry about your interests and intentions. You didn't. Ambiguity.

"Why do you care" is a question, but depending on your cultural background, it may get colored with tones of either "Why the hell do you care" or "may I ask why you're interested". Both are valid.

Nuclear forum wars start because a) People are ambiguous (go fly a kite sgbros you villager-murdering sack of shit, btw) b) and peeps knee-jerk-react to the tone they infer. Note that my original admonishment was directed at "folks", not you :)

Anyway, forum czaring is boring. Your energy situation is far more interesting.

The reason I care is because my big reactor requires ore and my solar does not and I would prefer my systems (I run a lot of IC2 stuff just because I like it=) to use the free energy before the one that costs me resources.

Your setup is nearly identical to my preferred one and translates nicely into that ideal. Centralize your power storage if you can, and use the redstone ports on your Big Reactor so that you can flip it on and off as needed.

There's a million ways to do this. If you have computercraft, you can do crazy things to scale back your Big Reactor output as your energy storage gradually changes. If you have Project Red or Blue Power, there's circuits available to help you flip your reactors on and off as needed (which is what I do)

I can help with the Project Red version if you decide to go that route, but all of them require that you have some way to store the power. As far as I know its the only way to ensure that your solar is being used 100% and your Reactors are only on when they need to be.

Pyure, I like your style.

I do have access to computercraft, although I have never used it. Can you recommend a "Computercraft for Dummies" guide?

Appreciated, and no, sorry, I can't. I'm terrible with computecraft. But I might be able to do one better.

@rhn is an automating genius. Also a world building genius. Actually he's essentially better at everything than me.

rhn can you point us to one of your Big Reactors adjusting scripts, please and thanks?

(Failing that, if rhn is unavailable, googling big reactors and computercraft scripts will get you what you need.)

If you know lua you know basically everything you need to know, for computercraft specific things there is http://www.computercraft.info/wiki/Main_Page
If you don't know lua then this might help

I personally learned lua by searching for code that does what I wanted it to do and trying to understand it, using google if I found something that I was unsure of about what it did.

Sorry for the long delay, been a bit absent. I prefer using this:
https://github.com/sandalle/minecraft_bigreactor_control

And I totally agree on centralizing your power production into a central hub. Be that RF, IC2 or whatever. With RF you can use the EnderIO Capacitor Bank and Power Monitors to then stage the power generators in the proper succession based on Capacitor Bank power level. With IC2 you can use Nuclear Control Range Triggers to do the same(trigger the output of a storage directly from a specific generator) based on the power level of a central bank of storage devices that supplies the base.

Logically it would draw from the closest as any power request or packet will use the first it comes in contact with.
To answer the why is this important question I would guess it has something to do with wanting to use a specific source first. If you have 2 cells feeding along a line one being leadstone and the other hardend. How would you place them allong the line so the hardened one empties first.
It could also just be a mechanics question made purely to sate curiosity.

I don't think it is necessarily the closest one first, but a matter of the first source processed after a "demand" is placed. So based on geography the "first" could be quite far away.

Imagine that every tick your computer/server scans through every block(that needs an update) in every loaded chunk. When it reaches your first RF power source it checks if it is connected to any conduits that are completely filled up(Conduits work by having an internal buffer). If not then it fills it up. Now the next power source it scans does the same but the conduit is full now, so it cannot send any power.
