Build a power station above ground with windmills
Building a power station above ground with windmills is a viable option for generating electricity in Rust. Here are some detailed instructions on how to achieve this:
Planning the Location
Firstly, you need to select an appropriate location for your power station. Choose an area with unobstructed wind flow, as wind turbines rely on consistent wind to generate power. Ensure that you have a clear line of sight to the east and west horizons to take full advantage of the wind throughout the day. Avoid placing the wind turbines too close to each other or surrounding structures, as this can impact their efficiency. A distance of at least 15 meters or 5 square foundations between turbines is recommended.
Constructing the Wind Turbines
When constructing the wind turbines, consider their height carefully. The higher a turbine is placed above the ground, the more power it will generate. Each floor above ground level can increase the power output, with some players reporting an average gain of 3.5 power per level up to 15 floors. Ensure that the third floor is free of obstructions, and the tower is at least 7 floors high. Additionally, the strength of the wind can vary over time, so expect fluctuations in the power output of your wind turbines.
Connecting the Power
Once your wind turbines are set up, you can connect them to a power source. Use electrical branches to connect the wind turbines to a large battery and a medium battery. This will allow you to store the generated power and distribute it as needed.
Maintaining Efficiency
To maintain the efficiency of your wind turbines, ensure that they are well-maintained and free of obstructions. Regularly check for any blockages in the path of the wind, as this will impact their power output. Additionally, be mindful of the surrounding terrain and structures, as these can also influence the wind flow and, consequently, the power generation of your turbines.
By following these steps, you can effectively build a power station above ground with windmills in Rust, providing a reliable source of electricity for your base or cave system.

Run power from the roof to a ground-level room
Running power from the roof to a ground-level room in Rust requires careful planning and consideration of the available resources and terrain. Here is a step-by-step guide to help you achieve this:
Step 1: Choose a Suitable Cave
Not all caves in Rust are created equal when it comes to running electricity. Look for a cave that allows external wiring from outside, such as the horseshoe cave or the second level of the sewer cave system. These caves provide more flexibility in running cables and wiring.
Step 2: Build a Power Station Above Ground
Construct a small base directly above the cave room where you plan to establish your base. This above-ground structure will house your chosen source of energy, such as windmills or solar panels. Ensure that you are positioned right above the intended area in the cave, and take into account the terrain to determine the best location for your power station.
Step 3: Run Cables from the Roof
With your power source in place, it's time to run the cables from the roof of the cave to the ground-level room. Cables can clip through walls and the ground, so start by building a room at the highest point in your cave. Place a splitter or a root combiner in this room as high up as possible, and then run the cables from your power source above to this splitter.
Step 4: Connect to Your Ground-Level Room
From the splitter or root combiner, continue running cables to your desired ground-level room. Ensure that the cables are securely connected and clipped through any obstacles to reach their destination.
Step 5: Consider Battery Options
Depending on your setup and power requirements, you may want to incorporate batteries into your system. Fully charged batteries can be moved and used to power turrets and lights as needed, providing flexibility and backup power options. Keep in mind that batteries may need repairs over time.
By following these steps, you can successfully run power from the roof of a cave to a ground-level room in Rust, allowing you to power turrets, lights, and other electrical components in your base.

Use a generator and keep refuelling it
One option for powering your cave base in Rust is to use a generator and keep refuelling it. This method has its pros and cons. Generators are simple enough to purchase from the outpost, and they're pretty cheap at 125 scrap to buy and an extra 75 to research. They're also the most reliable source of power for cave bases, as they can be placed indoors, safe from raiders. However, they can be troublesome to find, and the running costs can be steep—250 low-grade fuel per hour for a small generator.
If you decide to go with this method, you'll need to ensure a constant supply of fuel to keep the generator running. This could involve setting up a fuel production chain or regularly farming for fuel resources. Additionally, you'll need to consider the inefficiency of powering items underground; it may take a vast supply of low-grade fuel to power your desired items.
To optimise your setup, you can place the generator in a small, unattractive-looking base to deter raiders. You can also build the generator base right above the cave room where you're establishing your base. This way, you can run cables from the roof of the generator base to a room on the ground level of your cave base, using a splitter to manage the power flow.
It's worth noting that the cable clipping mechanics in Rust allow cables to pass through walls and even the ground, so ensure you build your generator base at the highest point to minimise the required cable length. With this method, you can power items such as auto turrets and lights, but be mindful of the fuel consumption and the potential need for a constant fuel supply.

Fill batteries above ground and move them underground
One option for getting electricity in caves in Rust is to fill batteries above ground and move them underground. This is because only a few caves allow you to wire electricity from outside.
Firstly, build a small base on the ground right above the cave room where your base is located. This base should contain your source of energy, such as a windmill or solar panels. You can then run cables from the roof of this base to a room on ground level, using a splitter. The cables can clip through walls and even the ground, so make sure to build a room at the highest point in your cave.
Place a splitter or root combiner as high as you can in that room, and then put a cable through the ground into your underground cave. A full large battery will power 3 turrets and some lights for 8-10 hours, so this setup should be sufficient to power your cave base.
You can fill batteries up top and move them underground once they are fully charged. Repeat this process as many times as needed, but remember to repair the batteries each time you replace them. This method ensures that you have a constant supply of power in your underground cave base without having to rely on inefficient generators or an external power source.

Bribe an admin to spawn a test generator
One option for getting electricity in caves in Rust is to bribe an admin to spawn a test generator for you. Test generators are not available in-game except when spawned by admins.
To spawn a test generator, the admin will need to access the item menu, which can be found by pressing F1 and then selecting "Items" at the top of the screen. From there, they should be able to select "Electricity" and spawn the test generator.
However, it's important to note that this method may not work for all caves. Additionally, some players may consider it unfair or unethical to bribe admins for in-game advantages.
Another option for powering your cave base is to build a power station above ground with windmills and run a feed into your power room in the cave. This requires you to be right above the cave and have luck with the terrain. Alternatively, you can run generators, but this may be inefficient and require a lot of fuel.
Some players have also suggested using batteries, which can be charged above ground and then moved down into the cave. This method can be repeated as many times as needed, as long as the batteries are repaired when replaced.
