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

Solar updraft tower ^[1]

Cost per Watt of capacity = 4 EUR ^[2]

Cost per watt of capacity (200 MW): 4 EUR, (50 MW): 6,04 ^[3]

50 MW (Spain, 1800) cost per Watt: 20 EUR^[4]

200 MW (Spain, 1800) cost per Watt: 12 EUR^[5]

+ Low maintenance cost.

+ Uses greenhouses that can be used for agriculture.

+ Produces energy at night at a reduced rate ^[6]

+ Produces energy when overcast ^[7]

+ May be able to desalize water by using condensation ^[8]

-Takes in a relatively large amount of space.^[9]

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, 2000) - 13 EUR (Netherlands, 900) ^{[10] [11] [12]}

+ Decentralized

- Variable output

Energy use

• Beamer

100-300 Watts. Can provide for +- 100 people. Per person: 2 Watt.^[13]

• Small led television

57 Watt. Per person: 14-57 Watt.^[14]

• Xbox

185 Watts ^[15]

• Wii

18 Watts^[16]

• Desktop (with peripherals):

60-250 Watts^[17]

• Laptop:

40 Watts^[18]

• Netbook:

16 Watts^[19]

• Tablet (Ipad2)

1-3 Watts ^[20]

• Iphone

Less than tablet^[21]

• Amplifier

40 Watts and up ^[22]

• DVD player

10 Watts and up

• Nanolight (100W equivalent, 30,000 hours)

12 Watts ^[23]

• Led lamp (50-60W equivalent, 50,000 hours)

6 Watts ^[24]

• Washing machine

0,81kwh/wash 1600 W average 9 year average 500 EUR^[25] (If 10 people share one machine: 36 years = 200 EUR per person)

• Dishwasher

175 Kwh ^[26]

• Refrigerator

>12 Watt ^[27] (374 L, no freezer, 700 EUR)

12 V refrigerator 4,7 Watt 50L (700 USD)^[28]

Monetary cost

Solar updraft tower

Collector diameter +- 750 meter = 400,000 m2 = 100 acre (60 soccer pitches)^[29]

Land price US +- 1,000 - 10,000 USD per acre

Argentina < 8,000 USD per acre ^[30]

100,000 - 1,000,000 for land

Cost of maintenance 40 years: +- 1,000,000 USD ^[31]

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.^[32]
