## Properties

### type :: `"electric"`

### buffer_capacity :: Energy optional

How much energy this entity can hold.

#### Example

    buffer_capacity = "5MJ"

### usage_priority :: ElectricUsagePriority

#### Example

    usage_priority = "secondary-input"

### input_flow_limit :: Energy optional

Default: Max `double` value

The rate at which energy can be taken, from the network, to refill the energy buffer. `0` means no transfer.

#### Example

    input_flow_limit = "300kW"

### output_flow_limit :: Energy optional

Default: Max `double` value

The rate at which energy can be provided, to the network, from the energy buffer. `0` means no transfer.

#### Example

    output_flow_limit = "300kW"

### drain :: Energy optional

How much energy (per second) will be continuously removed from the energy buffer. In-game, this is shown in the tooltip as "Min. [Minimum] Consumption". Applied as a constant consumption-per-tick, even when the entity is not active.

#### Example

    drain = "1kW"

## Examples

    energy_source = -- energy source of oil pumpjack
    {
      type = "electric",
      emissions_per_minute = { pollution = 10 },
      usage_priority = "secondary-input"
    }

    energy_source = -- energy source of accumulator
    {
      type = "electric",
      buffer_capacity = "5MJ",
      usage_priority = "tertiary",
      input_flow_limit = "300kW",
      output_flow_limit = "300kW"
    }

    energy_source = -- energy source of steam engine
    {
      type = "electric",
      usage_priority = "secondary-output"
    }
