An electronic controller 114 is configured to determine an operational schedule for a first electronic device 100 based on one or more emissions characteristics of an electricity supply grid 102, the electronic device 100 having a connector 118 for receiving power from the grid 102. The controller 114 may determine, as part of the operational schedule, an operational-event start time, end time, duration and/or minimum level of emissions characteristics. The emissions characteristics may indicate a proportion of energy supplied by a type of energy source, which may be renewable, solar, tidal, wind, nuclear or fossil fuel. The emissions characteristics may comprise predicted grid emissions, which the controller may determine based on current or historic grid emissions and/or predicted, current or historic weather forecast, daylight, climate and/or tidal information. An operational-even start time may be scheduled when any of the emissions, proportion of power from a particular source, weather forecast, daylight, climate and/or tidal information satisfy a threshold level. The controller may determine the operational schedule in accordance with the operational schedules of one or more second electronic devices. The schedule may be a charging schedule and may be determined in accordance with a target charge level. |
