One household won't notice much difference, but if everyone unplugged their
wallwarts and turned off (instead of let sit on stand-by) their computers I
bet there would be quite the loss in consumption.

Even more so with TVs left on standby, there are more of them in use
than computers.

Yeah. :)
All my stuff like that is hooked up through a "power strip" and
turned off with one switch. One for the computer and its stuff
and another for the TV and its stuff.
My antenna pole has been stuck by lightning at least 3 times (that I
was here to witness) and since I'm about as high as anything around
here, during that season the antenna is disconnected too and only
connected when it's being used. It was disconnected the first time
it was stuck and so only burned up the house wiring and out-building
wiring.
That first bolt was a whopper and some of the electricity "spilled
over on me". I woke up laying on my back with my arms and legs
in the air like a dead cockroach. All my muscles were frozen and
as tight as they could posibly be, even my diaphram. I couldn't
move and I couldn't breathe. "shear terror"
It was cool! :)
No, I don't want to be struck again, thank you, once was enough.
I'm a retired railroad signal ape and can say, that bolt that got me
wasn't anywhere near the strongest, but was a good solid stike
anyway, the next two were more typical. There's been several times
I opened a signal case full of relays and lightning arrestors, to
"hunt down the signal trouble" and "couldn't see anything in the he
case" because it was -all- one flat-black color. It looks creepy as
anything.
Anyway, I figure I only -got- about 1%.
It -felt- like the whole friggin thing tho! :)
Believe it? ;)

This computer, the on I'm running right now (750Mhz AMD K7 T-Bird),
net ID lazarus, was struck by lightning about three years ago (2003).
Well, it actually hit outside on the driveway, but a lot of my electronics
got fried - including this computer!
Power had just gone off, but the cpu was on battery - shutting down - when
it hit.
When the lights came back on (reset all the breakers) the VCRs and TVs (2)
were all gonzo, but the computer tried to start up - and then
Smoked!
Badly!
Stinky Black power supply smoke!
Along with a bright yellow glow from the back of the box!
I remember being dumbstruck thinking "It normally doesn't do that...",
before swatting the switch off.
Which did cause the "glow" to go out immediately, but it just rolled smoke!
A few days later, figuring "what the heck" I swapped out the power supply,
and the machine came up an ran, sort of. Cad was no problem, but it would
hang up on things it used to do just fine... couldn't dial!
I did a careful visual exam of the motherboard and found every one of the small
electrolytic capacitors had the tops blown off. Little round tops hinged over
to one side and the stuffing's oozing out - like tiny spinach cans in a Popeye
cartoon.
So I made a list, found all the right caps (which all looked a lot better quality
than the originals, btw) and very carefully replaced them one at a time.
And finally replaced the modem to get back on line.
And it rocks on...
But under a new name: lazaruz
For what it's worth?
That was out in the country - local shore power not exactly always stable.
I had a battery backup on the cpu/monitor (with surge suppressers)
Surge suppresser on the master power switch box.
Surge suppresser on the printer power outlet strips (2).
Surge suppresser on the laptop circuit (Laptop not connected at the time)
All in one room.
And the phone line physically disconnected.
Yet it still somehow fried the modem...
Now somebody explain that one!

"could come up with a thousand senarios and none of them would be
exactly right" ...is my typical answer, just before I procede to
speculate my ass off. ;)
Easy. ;) The dangged lightning can jump miles outside and jumps from
one thing to another (at-will;) inside. BTSeenT when looking at the
evidence of it and it sometimes makes no sense at all why it chose
that particular path (other than lightning has no sense and makes no
choices?;).
The bolt that got me had -at the very least- jumped 1+1/4" between
metal objects, then through me to ground. It was the first bolt
from two clouds that came together at about a 90 degree angle...
I was watching them hoping it'd rain. It was late June in the
desert and the first rain is a big deal for us born here.
