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.

Contents

Energy generation

Solar updraft tower [1]

1 MW = 3,8 million EUR (+cost of land: approx 100,000-1,000,000) [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

1 MW = 1,8 million EUR (most sunny areas)

1 MW = 2,9 million EUR (least sunny areas)

The most important solar regions of Romania are the Black Sea coast, Dobrogea and Oltenia with an average of 1,600 kWh/ m2/year

960 kwh / m2 / year = 109 W m2[3]

1 m2 = 200 eur[4] = 109 W

+ Decentralized

- Variable output

Energy use

  • Beamer

100-300 Watts. Can provide for +- 100 people. Per person: 2 Watt.[5]

  • Small led television

57 Watt. Per person: 14-57 Watt.[6]

  • Xbox

185 Watts [7]

  • Wii

18 Watts[8]

  • Desktop (with peripherals):

60-250 Watts[9]

  • Laptop:

40 Watts[10]

  • Netbook:

16 Watts[11]

  • Tablet (Ipad2)

1-3 Watts [12]

  • Iphone

Less than tablet[13]

  • Amplifier

40 Watts and up [14]

  • DVD player

10 Watts and up


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

12 Watts [15]

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

6 Watts [16]


  • Washing machine

0,81kwh/wash average 9 year average 500 EUR[17] (If 10 people share one machine: 36 years = 200 EUR per person)

  • Dishwasher

175 Kwh [18]

  • Refrigerator

>12 Watt [19] (374 L, no freezer, 700 EUR)

12 V refrigerator 4,7 Watt 50L (700 USD)[20]

Monetary cost

Solar updraft tower

5 USD per Watt, so 1 MW tower = 5 million USD [21] (Schlaig 2005)

This report from Schlaig (1995) suggests a 1 MW tower would cost no less than 20 million USD.[22] 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)[23]

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

Argentina < 8,000 USD per acre [24]

100,000 - 1,000,000 for land

Cost of maintenance 40 years: +- 1,000,000 USD [25]



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.[26]
