@notplants @werbefrei after 10 years in a hot environment the linked below uses a little over 2kW. Running 16 hours a day that leads to 11,913kWh a year. (Cool and new 9,460kWh)
The average house in the worst state of Australia uses 8,619kWh a year, 4,615 for the best state.
So plausible if you pick the numbers you want.

for bringing attention to the question,
why are we spending energy day and night on these electric ads at all when there are real needs elsewhere... but always an interesting question to me how to draw the line between poetic and misleading communication... I find it good to know that its not a completely ridiculous claim though and appreciate your impulse to research ... as technically someone could grafitti anything there and take a photo of it
Sunbeam City is a anticapitalist, antifascist solarpunk instance that is run collectively.
