'''电（Electricity）''' 被作为《太空工程师》中使大多数设备工作的能源系统存在。
:
游戏中，电能可通过《发电》类设备生产获得，供给《网格》（含《相连网格》）的《用电》，还可安装《蓄能》设备缓冲电力产能，以作后备供电源用。

====多主题相关小提示====
《同网格》 以及 《互连网格》 上的所有设备共享电力


== 电 的计算 及 基础认知 ==
《太空工程师》中，
*任何能量传递和转化的效率（即：功率）以 '''瓦'''（或[[wikipedia:watt|'''W''']]）为记量；下列图表中也会遇到高量级单位'''千瓦'''（或'''KW'''）、'''兆瓦'''（或'''MW'''）。
*电能量的衡量（即：电功）以'''瓦时'''（或[[wikipedia:kilowatt hour|'''Wh''']]）为记量（时一般以小时计）；意思是 以某功率 持续作业多久（即：功率 x 作业时间）。
*:举个例子：用电设备工作功率 500瓦 ，需要工作 5小时，用于供电的电池设备 需储备电能量为 500瓦（W） x 5小时（h） = 2500瓦时（Wh） = 2.5千瓦时（KWh）
:
游戏中在蓄电和供电设备信息界面中会常常接触到这些电学数值，下表有助于记忆不同量级单位转换时的比值关系。

发电装置中的，核发电站 反应堆 以 [[Uranium Ingot|铀锭]] 为原料发电，其 1公斤（kg）可产出 1兆瓦时（MWh）电能量
:规模更大的核发电站，只是加速反应，缩短时间，料能效率不变。
:大网格的“[[Small Reactor|小型核反应堆]]” 供电功率为  15兆瓦（MW），只需要  4分钟（ 0.06~小时）就可令1公斤原料反应完毕（产出 1兆瓦时 电能量）
:大网格的“[[Large Reactor|大型核反应堆]]” 供电功率为 300兆瓦（MW），只需要 12秒钟（0.003~小时）就可令1公斤原料反应完毕（产出 1兆瓦时 电能量）
:
电池蓄电效率为80%，放电无损耗。
:大网格的“[[Battery|电池]]” 满足蓄电功率上限 12兆瓦，从0蓄电到3兆瓦时（MWh）满充需要 18.75分钟（需实多段计时测量），而此时耗理应可充3.75兆瓦时，其中这0.75兆瓦时被浪费（即蓄电效率80%，浪费20%），但放电无损耗
:因此从抑制浪费的角度而言,用不可持续核电[[Reactor|reactors]]还是可持续发电(比如太阳能[[Solar Panel|solar panels]] )的之间,太阳能更适合为电池充电.
:电池会试图为自己充电?
:电池为电池充电,放电方无损耗,蓄电方效率80%.

=== 电能配给优先策略 ===
[[File:Ship_reactors_off_display.jpg|thumbnail|In the event of power failure or a power deficit, the grid will also prioritize what receives power.旧版才能看到的界面]]
《太空工程师》的电能被策略性地定义了一个优先顺序，分别为需要发电的优先次序和基于耗电权的优先次序，

*'''发电次序策略'''：在设备需电时，由可持续供电设备优先供电，然后由燃料供电设备补足，最后由后备供电装置支持
:# [[Solar Panel|太阳能板]] 和 [[Wind Turbine|风轮机]] ：均为可持续供电设备，虽然供电能力不大，且可能受环境或方位影响，但方便直接，无需燃料。
:# [[Hydrogen Engine|氢气引擎]] ：采用低价值的氢气为发电燃料；需要提供氢气库存，氢气的能效并不高。
:# [[Large Reactor|大号反应堆]] 和 [[Small Reactor|小号反应堆]] ：采用高效但极端昂贵的铀锭为发电原料（铀矿非常稀有，铀锭的制取相当耗时，购买又昂贵）
:# [[Battery|电池]] ：角色就是后备电源，应急而用；并且会因为蓄电浪费20%充电的电能

:
*'''给电次序策略'''：
:对用电设备按功能归类并划分了用电的次序，设备可适应电能供量而调整输出大小的（比如推进，电池）会排在后序，而那些不足电量就会自动停机的设备（比如输送，防御）会排在相对优先；电池的蓄电排在最后。
:# （防御）Defense   - [[Interior Turret]], [[Missile Turret]], etc
:# （输送）Conveyors - [[Conveyor]], [[Conveyor Tube]], blocks that make up the [[Conveyor Network]], etc
:# （生产）Factory   - [[Refinery]], [[Assembler]], [[Oxygen Generator]], [[Air Vent]], [[Oxygen Tank]], etc
:# （门控）Doors     - [[Door]], [[Airtight Hangar Door]], etc
:# （应用）Utility   - Communications, Lights, [[Rotor]], [[Piston]], [[Medical Room]], [[Gravity Generator]], the vast majority of electronics, etc
:# （充能）Charging　- [[Jump drive]], specifically players inside cockpits or passenger chairs, recharging their suits.
:# （翻滚）Gyro　    - All [[Gyroscope]]s
:# （推进）Thrust    - [[Small Thruster|Standard Thrusters]], but not [[Small Hydrogen Thruster|hydrogen based thrusters]]
:# （电池）Batteries - Any [[Battery|Batteries]] attempting to charge themselves.

<!--
It can be stored in a  and discharged to the [[grid]] it is built on. 
Any device that has a direct [[Blocks|block]] connection to a power source will be powered by that power source;
that is, if a reactor is on a ship, all devices attached to that ship should receive power - provided there is enough power to supply all active blocks on the grid.

Most blocks have off switches if you want to save electricity temporarily, which is particularly useful in [[Survival Mode]].

(*) Solar Panels have a maximum output depending on their angle to the sun and the amount of actually lit surface. Given values are the maximum achievable output with perfect conditions, therefore efficiency and output may vary.

=== Large Reactor vs Small Reactor ===

Comparing them directly, the small reactor provides far more energy for the space it takes up; for example, 20 Small Reactors is equal to the output of a Large Reactor with only two-thirds of the space used. Despite this the large reactor offers greater economies of scale, requires less [[Conveyor]] complexity and in general is more useful in a variety of important applications especially as Powerplants for Large Ships, being both lighter and requiring fewer resources to construct. This makes Large Reactors ideal for ships that can take advantage of their reduced mass and accelerate or decelerate more easily, and therefore use less [[Uranium Ingot|Uranium Ingots]]. Small Reactors are therefore ideal for stations that do not need to move, situations where physical space is precious or presents relatively light power needs that would not require a larger more expensive reactor. For example, a large reactor only needs 40 [[Metal Grid]]s while a small reactor needs 4 Metal Grids at approximately 10 Small Reactors (150 MW) you would start to see economy of scale benefits clearly when using the large reactor. Between them however, they use [[Uranium Ingot|Uranium Ingots]] equally as efficiently neither one will manage to extract more energy than they would otherwise have to.
