I think the design philosophy is that each tile represents no more than a single entity at a time, and compact enough that you can arrange the entities in a section to represent a device, room or group.
In your example, perhaps the room also has a humidifier and/or heater. So in reality, the room temperature entity isn’t truly tightly coupled with the fan. The heater and or humidifier are also a part of the whole.
With tiles, you are in complete control to arrange groups of entities that represent a larger whole, in whatever scope you like.
The plastic (including polyester fabrics) in your car was most likely derived from petroleum. The car parts were most likely shipped around during manufacturing using combustion engine vehicles. The energy to cast those car parts, probably some of it comes from non renewables. The labour to build the car almost surely comes from other people who consume gas (for example to drive to the EV factory)
That “100%” renewable energy? The installation and maintenance of it was/is almost certainly done with large industrial equipment and vehicles burning fossil fuels. (Similar issue with production of parts).
Look, I’m not saying you aren’t making positive choices by choosing renewable options. What I am saying is, while they are more renewable, they aren’t truly 100% renewable when you factor everything involved in it. Fossil fuels are so pervasive in society, it’s virtually impossible to both function in a modern society and not contribute to the consumption of fossil fuels.
