How Much Power is 1 Gigawatt?

Today marks the one-year anniversary of “Back to the Future” Day.

It’s a date most movie buffs know by heart: October 21, 2015 – the day Marty McFly and Doc Brown travel to the future in Stephen Spielberg’s 1989 classic “Back to the Future: Part II.”

Although you may not have remembered the date, you’ve probably heard of Doc’s DeLorean, which takes 1.21 gigawatts (GW) of power to travel through time. Admittedly, our national labs haven’t quite figured out time travel just yet, but they do analyze power.
