I have already taken into concern renewable sources and several other factors.
Here is what I have so far:
Homes
The homes are all at the borderlines of the city. They are chambered and most of what is in the homes is underground. This gives room for wild animals while still allowing a civilization to thrive.
Buildings
The buildings are more towards but still not quite at the center of the city. There are 2 hospitals, 1 general and 1 children's as well as a bank, a store, a restaurant, a lab, and 5 schools.
Education
This education hasn't been established except for 5 basic levels. Those are preschool, elementary, middle, high, and college.
Food
Robin and Lisa have more than enough fruits and vegetables. They don't have any domesticated animals used for meat or eggs yet. Meat and eggs is handled by hunting. Hunting is 1 of a female's jobs. Males do it too but only when the females can't do it.
Light and Time
This is 1 big issue. However, I have solved it by having part of the homes and buildings above ground and the people doing just as well above ground. At least, I think I have. Time during the night is not nearly as important as during the day.
Ventilation
Oxygen easily gets into this underground system via diffusion and likewise CO2 easily goes out. Plants also draw CO2 from the atmosphere, facilitating diffusion of CO2 from high concentration(underground) to low concentration(atmosphere) Oxygen goes the opposite way again via diffusion. And this keeps happening. The only way these people get hypoxic underground besides lung and heart issues is if tunnels collapse on them. This tunnel collapse leads to injury and in some cases hypoxia. Ventilation is no problem.
Questions
1) Will simple diffusion really work for gas exchange between the underground system and the atmosphere like it does in human gas exchange? In other words would this whole biosphere(underground system with people producing CO2, Plants on the surface producing O2, Bacteria producing both those 2 and more) be like giant lungs?
2) Even with part of every building and home above ground, will this sunlight(or moonlight at night) work all the time for telling daytime from nighttime? I mean, it will probably work most of the time but is there a point where the difference between sunlight and moonlight is so miniscule that I will truly need lights there? I know that sometimes(but rarely), moonlight can be just as bright as sunlight(I sometimes get moonbeams in my room from all the moonlight outside).
3) If an earthquake happens, will people underground be in more danger than people above ground or not? I can think of several pros and cons for each.
Stay underground Pros:
Minimum risk of communicable illness
Babies already born kept safe from injury
Most familiar territory so less stress
Stay underground Cons:
Aspiration pneumonia(not an illness but nevertheless a concern)
Risk of hypoxia in tunnels
Risk of injury anywhere but especially in tunnels(fractures, myalgia(muscle strain), organ failure due to loss of oxygen)
Above ground Pros:
Quick evacuation
Knowing the duration of the earthquake
No aspiration pneumonia
Above ground Cons:
Higher risk of injury than underground(fractures, impaled, burns)
Babies aren't safe(could jump out of sling and get injured due to the shaking)
Higher risk of illness(bacterial, viral, fungal, parasitic, doesn't matter)
Universal Cons:
Nausea(In already nauseous people, this could be dangerous)
Preterm labor and miscarriage(stress increased during pregnancy)
Not able to breastfeed(Same thing, stress can dry up milk supply)
