    "A lightning strike lasts only a few milliseconds but carries 1000 Watts of power"

    There are other curious facts about lightnings in this webpage

    I read the link, but I can't believe this is accurate.

    Using:

    Watts = volts x amps

    amps for a lightning strike 100 to 40,000

    volts = 100 MV to 2 GV

    I'm seeing several gigawatts here.

    Here is another link.

    Agreed. Several gigawatts sounds more like it.
