Alexandria was built as a self sustaining community. So it has solar power, water reserves etc. But it doesn't have a food supply.

 

It's a fictional tv show on AMC. Not a documentary on the Discovery Channel.

 

We are suppose to have the impression that it runs off the solar panels. Remember in Spend, when they took Eugene to the warehouse to get the inverters? They were for the solar panels. Sam told Carol his house had no power that day, before the group came back with the inverters.

Of course, its unrealistic to depict a dozen houses and a huge brownstone building all powered by that one group of solar panels. I went through and calculated it last year, and it would be enough power, ballpark, for about 2 refrigerators total in the safe zone, plus each house to have maybe two 60 watt bulbs on for a total of 4 or 5 hours per day, plus each resident [based on 50 people] to take about a 60 second lukewarm shower maybe twice a week. That doesn't include the medical equipment, the ovens/stoves [which much be electric, if they are working, as there is no gas company nearby], or heating the houses in winter, among other things.

They also could be getting energy from propane, but we haven't seen any tanks.

Water pressure could still theoretically come from a water tower nearby [there actually is one, a block away [[Woodbury]], we've seen it in the background], but once that went dry, there would be no power to pump it full again.

 

You're a good sport.

 

Reg did it. He was like, a genius man.
