Carbon Intensity

What

Shows the actual and forecast carbon intensity in gCO2/kWh using data from the Carbon Intensity API.

note

Note that this segment only provides data for Great Britain at the moment. Support for other countries may become available in the future.

Sample Configuration

caution

The API can be slow. It's recommended to set the http_timeout property to a large value (e.g. 5000).

Properties

Name	Type	Default	Description
http_timeout	int	20	Timeout (in milliseconds) for HTTP requests. The default is 20ms, but you may need to set this to as high as 5000ms to handle slow API requests.

Template (info)

default template

CO₂ {{ .Index.Icon }}{{ .Actual.String }} {{ .TrendIcon }} {{ .Forecast.String }}

Properties

Name	Type	Description
.Forecast	Number	The forecast carbon intensity in gCO2/kWh. Equal to 0 if no data is available.
.Actual	Number	The actual carbon intensity in gCO2/kWh. Equal to 0 if no data is available.
.Index	Index	A rating of the current carbon intensity. Possible values are "very low", "low", "moderate", "high", or "very high". Equal to "??" if no data is available.
.TrendIcon	string	An icon representation of the predicted trend in carbon intensity based on the Actual and Forecast values. Possible values are "↗", "↘", or "→".
