# ElectricityInsightRecord.GridCleanliness

A structure that describes the environmental impact of grid electricity during specific time periods.

```
struct GridCleanliness
```

## Overview

The [`ElectricityInsightRecord`](/documentation/EnergyKit/ElectricityInsightRecord) structure’s [`dataByGridCleanliness`](/documentation/EnergyKit/ElectricityInsightRecord/dataByGridCleanliness) property returns electricity usage by the categories that this structure defines.

The type of electricity usage that this structure stores depends on the generic type parameter of a given [`ElectricityInsightMeasure`](/documentation/EnergyKit/ElectricityInsightMeasure) instance. If the generic type is:

- <doc://com.apple.documentation/documentation/Foundation/Measurement><<doc://com.apple.documentation/documentation/Foundation/UnitEnergy>>:
  The electricity usage refers to energy consumption or generation.
- <doc://com.apple.documentation/documentation/Swift/Duration>:
  The electricity usage refers to an amount of time that an electrical device is operational and consuming energy.

## Topics

### Initializing the grid data

[`init(cleaner: Measure?, lessClean: Measure?, avoid: Measure?, unknown: Measure?)`](/documentation/EnergyKit/ElectricityInsightRecord/GridCleanliness/init(cleaner:lessClean:avoid:unknown:))

Initializes the collection of grid cleanliness data.

### Getting grid cleanliness information

[`var cleaner: Measure?`](/documentation/EnergyKit/ElectricityInsightRecord/GridCleanliness/cleaner)

A category for electricity usage during the cleanest grid periods.

[`var lessClean: Measure?`](/documentation/EnergyKit/ElectricityInsightRecord/GridCleanliness/lessClean)

A category for electricity usage during less-clean grid periods.

[`var avoid: Measure?`](/documentation/EnergyKit/ElectricityInsightRecord/GridCleanliness/avoid)

A category for electricity usage during periods that the framework suggests a person avoid.

[`var unknown: Measure?`](/documentation/EnergyKit/ElectricityInsightRecord/GridCleanliness/unknown)

A category of electricity usage when grid cleanliness information is unavailable.
