Energy can be saved through sharing appliances (for instance by using a beamer to watch film and television). Energy plays an important part in automation.

Energy generation
Energy generation
Solar updraft tower [1]
Cost per Watt of capacity = 4 EUR [2]
+ Low maintenance cost.
+ Uses greenhouses that can be used for agriculture.
+ Output is less variable compared to other solar methods
-Takes in a relatively large amount of space.
Solar power tower
+Desalinizes water.
+Contains a furnace (that can be used for melting iron for instance).
-Solar has a variable output.
PV panels
Cost per Watt = 6 EUR (Africa) - 13 EUR (Netherlands) [3]
+ Decentralized
- Variable output
Energy use
- Beamer
100-300 Watts. Can provide for +- 100 people. Per person: 2 Watt.[4]
- Small led television
57 Watt. Per person: 14-57 Watt.[5]
- Xbox
185 Watts [6]
- Wii
18 Watts[7]
- Desktop (with peripherals):
60-250 Watts[8]
- Laptop:
40 Watts[9]
- Netbook:
16 Watts[10]
- Tablet (Ipad2)
1-3 Watts [11]
- Iphone
Less than tablet[12]
- Amplifier
40 Watts and up [13]
- DVD player
10 Watts and up
- Nanolight (100W equivalent, 30,000 hours)
12 Watts [14]
- Led lamp (50-60W equivalent, 50,000 hours)
6 Watts [15]
- Washing machine
0,81kwh/wash 1600 W average 9 year average 500 EUR[16] (If 10 people share one machine: 36 years = 200 EUR per person)
- Dishwasher
175 Kwh [17]
- Refrigerator
>12 Watt [18] (374 L, no freezer, 700 EUR)
12 V refrigerator 4,7 Watt 50L (700 USD)[19]
Monetary cost
Solar updraft tower
5 USD per Watt, so 1 MW tower = 5 million USD [20] (Schlaig 2005)
This report from Schlaig (1995) suggests a 1 MW tower would cost no less than 20 million USD.[21] The data is older, but it does account for rising cost when plant is smaller.
Collector diameter +- 750 meter = 400,000 m2 = 100 acre (60 soccer pitches)[22]
Land price US +- 1,000 - 10,000 USD per acre
Argentina < 8,000 USD per acre [23]
100,000 - 1,000,000 for land
Cost of maintenance 40 years: +- 1,000,000 USD [24]
100 W capacity per settler when the sun is shining. This means using anything other than a tablet / smartphone is advised against. Watching television by yourself or with a handful of people should also not be a habit.
A 1 MW solar plant will produce +- 0.25 MW average over a 24 hour day.[25]
