There's a philosophical discussion to be had here regarding the difference between a gigawatt and a jigawatt!

[airstrike]

Technically "jigowatts" per the script http://www.dailyscript.com/scripts/bttf4th.pdf even though they really meant it to be gigawatts

[jokteur]

In the french dub, they say jigowatt.

Also could be very little energy depending on how long they needed to apply the power.

Well a lightning bolt solved that problem, so...
