## Methods

### get_input_flow_limit(quality?) → double

#### Parameters

quality | :: QualityID? |

### get_output_flow_limit(quality?) → double

#### Parameters

quality | :: QualityID? |

## Attributes

### buffer_capacity :: Read double

### usage_priority :: Read string

### drain :: Read double

### emissions_per_joule :: Read dictionary[string → double]

The table of emissions of this energy source in `pollution/Joule`, indexed by pollutant type. Multiplying it by energy consumption in `Watt` gives `pollution/second`.

### render_no_network_icon :: Read boolean

### render_no_power_icon :: Read boolean

### valid :: Read boolean

Is this object valid? This Lua object holds a reference to an object within the game engine. It is possible that the game-engine object is removed whilst a mod still holds the corresponding Lua object. If that happens, the object becomes invalid, i.e. this attribute will be `false`. Mods are advised to check for object validity if any change to the game state might have occurred between the creation of the Lua object and its access.

### object_name :: Read string

The class name of this object. Available even when `valid` is false. For LuaStruct objects it may also be suffixed with a dotted path to a member of the struct.
