Surface Area Required To Power The World (revision)

My reworking of the brilliant Land Art Generator images 'Suface Area Required To Power The World' with one alternative energy source added :)

===========

 

here's my maths (probably wrong, please correct me if so)

  

total world energy needs per year:

198,721,800,000,000 kwH

 

average energy output of a human per hour

0.1 KW per human (100 watts)

 

365 days at 24 hours a day = 8760 energy hours per year per human

 

0.1 KW x 8760 hours = 876 KWh energy generated per human per year

 

world energy needs divided by human supply

 

198,721,800,000,000 / 876 = 226,851,369,863 humans required

 

Human body occupies

 

2m x 1m = 2square metres

 

assuming machinery and spacing between human batteries

 

4m x 2m = 8 square metres

 

requires

 

1, 814,810,958,904 metres for all human batteries

 

1.8 trillion square metres

 

or

 

18,148,810,958 = 18 billion square kilometres

 

world land surface area is:

 

148,940,000 square kilometres (wikipedia)

 

so would require 221 billion humans to be stacked 121 rows high across the entire land surface of the earth.

 

very dystopian!
