The world consumes energy at the rate of about $466 EJ$ per year, where the joule$(J)$ is the SI energy unit.
Convert this figure to watts$(W)$ , where $W= 1 J/s$, and then estimate the average per capita energy consumption rate in watts.
I'm having trouble understanding this problem. Can someone please explain me in detail the way to solve this problem. First of all I do not know what the unit $EJ$ represents, is it $exajoule$?
