If the world consumption of electricity is 17.78 trillion kWatt-hours per year, how much electricity does the average person in the world use per year?

Question

I am unsure what classifies a average person. Need help solving

Answer 1

Divide by total number of people in the world

 

$17.78 x 10^12
number of people is 7.6 x 10^9

17.78 x 10^12 / 7.6 x 10^9 = 2,339.5 KW-H per person
