This storyboard does not have a description.
Paul is hesitating whether to turn the washing machine on now or wait until later.
It strikes him that he meant to check how much electricity it actually takes each time to do the washing.
Before turning on the machine, he launches the new app that he downloaded to see how much electricity the machine uses.
The app lets him set the duration of the washing programme - but also the time of use. In doing so, Paul sees that by doing his washing in the evening, off peak hours, he can save half of the cost.
He also discovers that the electricity he is buying comes from fossil fuels and generates a lot of pollution.
He decides not only to postpone the washing but to modify his electricity supply contract to opt for certified green energy.
