Immaculate City uses windmills and solar power as their main way to get power. The oceans that surround the city are pollution free. All around the city are recycling bins because the objects you want to dispose of, can be easily recycled and made into something new.
All the residents have similarly styled homes. The Food Delivery Service is out (in their solar powered vans) on their daily routes to deliver the neighborhood groceries.
All the kids are getting along and nobody is being left out.
