The global energy consumption is currently about 420 ExaJoules per year. Exa- is 10^18, thats a round quintillion, a billion billion. hmf!
- giga- 10^9 – your hard disc
- tera- 10^12 – notnotabouthim‘s hard disks
- peta- 10^15 – really big
- exa- 10^18 – just frickin huge
I so rarely get to use the “exa-” prefix. It makes me happy when I do.
