At Mediamatic in Amsterdam, a new exhibit allows visitors to meet their animal energy avatars. Part of the New Order series exploring energy consumption in a world fully supplied by renewable resources, the installation displays animal forms representing the actual energy consumption of human participants.
The exhibitors explain that once-upon-a-time human energy consumption was directly related to metabolic rate.* For example, asleep, humans require 90 watts. Hunter gatherers in the Amazon require 250 watts. With modern technology, though, middle-class humans in the developed world consume around 11,000 watts—more than a blue whale.
* Plus shelter and heat requirements, I think. But we get the idea.
