Well you didn't read the article because the comparisons of the energy consumed are listed in Ws (Watt Seconds)

e.g.

> We can now boot into a Linux user space program in less than 3.5s!

>~400ms is spent in the Linux kernel (difference between pin 0 and pin 1)

>Total energy consumption: 0.364 As * 5.0 V = 1.82 Ws
