So I was at work today and my mind wandered a little.
To the point I did a little googling, then made a little spreadsheet.
According to the ever correct Wikipedia, worldwide electricity usage for 2012 was 20,900TWh.
Divide by 365 gives us 57TWh per day.
if the cells average 2500mah, then that's 9Wh per cell. 57TWh divide by 9 gives 6,362 trillion 18650 cells. We are talking 6 quadrillion cells here.
And that answer made me sad.
but then I wondered how many that would be per person.
7.6 Billion people on earth.
its 837 cells per person.
Well damn!! That sounds possible!
Of course, we'd need something renewable to power that lot.
Plus i don't know if worldwide electricity requirement is increasing or decreasing. Data from 2012 is a bit old now.
And this is only electricity consumption. Not all energy. Whats the general rule of thumb? 1/3 electricity 1/3 heating 1/3 transportation? Something around that.
Still. Was an interesting thought
