Maybe we use too much energy then.
We waste so much electricity. Many of the modern TV's use energy to keep the picture
tube warm will it is off. I don't know how much this is but, since I began to unplug
my television when I am not using it, I have noticed a about a $1-$1.50 drop in my
monthly electric bill(1). Same thing with VCRs, etc.
I read a report in New Scientist a about 1-2 years ago that said when Britian switches
over to HDTV, it's going to require about 500 MW of power, even when the TV are not
turned on. I think that figure is about 1% of Britian's current energy needs.
This is just an example of how we waste energy all the time without even realizing it.

1- just an estimate, having a second person in the house has changed the electricity
use.
