How Much Power Is 1.21 Gigawatts, Anyway? The Science Behind Back to the Future (www.syfy.com) angielski

Back to the Future's 1.21 gigawatts sounds huge, but is it? We compare different power levels of common objects to see how much energy a gigawatt really is.

This article is completely wrong.

Watts doesn’t have a time factor at all.

Power is measured in W (Watts).
Energy is measured in J (Joule’s), or Wh (Watt-hours) where 1 Wh = 3600 J.

So 1.21GW is enough power to light 12.1 million 100 W bulbs, if you kept them powered for 1s you would use 1.21GJ of energy, which is 3.36MWh.

I can’t believe how badly the article gets it wrong.

I’m an engineer, I work with this stuff regularly.
