Power

Description
Power (or energy/electricity) is another essential resource that is vital to success !

Whereabouts
Energy, much like Oxygen, can be found on the surface of planets as well as inside caves, in the form of spires, or yellow ore deposits. Energy is also supplied from base modules and vehicles, as long as there is power available in surplus or it is being generated. To maximize this effect use tethers to have access to power while under ground, or far away.

Usage
Energy is used to power base modules, your terraforming tool, and can be stored in batteries. It is useful for nighttime, or when you are relying only on solar power.

Energy can be :
 * Mined from the environment in raw form.
 * Produced from nothing by some items like small and big solar panels and wind vane/turbine.
 * Produced while consuming either organics or coal by generators.
 * Stored in stacks of raw energy or in various kinds of batteries.
 * Distributed to a network using big cables between buildings in a base or to distant players via tethers.

Network
A network is just a series of buildings and tether connected to each other.

Except that tether can only bring energy to the player's backpack. So tether cannot "electrically" connect two separate networks (two bases).

Currently, you can only connect two networks using the cables that comes out of the front and back of a rover or truck. (TODO : test this).

Also a bug makes that within the same network, sometimes, energy cannot flow from or to some buildings.

Battery behavior
TODO : needs closeup screenshot of a main battery half full, or even a gif of it charging.

Batteries are composed columns (usually 4, 8 or 16 columns), each column being composed of a stack of 4 units. The exception being the backpack's main battery which is a single column of 10 units. Units are black when empty and yellow when full.

That's why energy production of some items (solar panel, energy stack, ...) is expressed in units/seconds or columns/seconds (or seconds/column when it's clearer).

The backpack, modules and vehicles each have a main battery, which is only depleted for their main use (deform tool, production of something and movement, respectively). Buildings (modules) will always consume all their battery when activated and require it to be completely full.

Main batteries never gives energy to the network that require some, in opposition to to the small and big batteries. They even have priority over those ones when energy flows in the network : main batteries will be filled before every other batteries.

When an energy-producing apparatus is placed on a module or vehicle, the energy will be placed in the module or vehicle main battery first, before being given to other systems that needs it in the network.

In addition to the main batteries, you can craft small and big batteries, which can be printed in the backpack and Printer module, respectively. These batteries will give away their energy to any main battery in the network that isn't full. They will only fill up when all main batteries in the network are full.

Energy stacks
When harvested from the environment by a player whose backpack battery is full, energy stack up in the deform tool then in the players backpack slots like any other resources. An energy stack can then be moved and put to any one slots anywhere in the backpack, modules, vehicles or storages. When needed by a main or secondary battery, energy will be drawn from the stack which will disappear over time.

Stacks gave their energy at the high rate of 4 units/sec, or 1 sec/column (twice faster than the solar panel).

A full stack is enough to fill 8 columns of a battery in 8 seconds.

TODO for this paragraph : move that to its own resource page, add it to the list of resources, add the content of the "whereabouts" paragraph.
