I know.... you are right

I'm just an "optimizer" by nature and cant help myself!

I'm the same.

But....... if there are 400 million people in the USA
and say 100 million homes.... and if we save just ONE
watt in the fridge bulb.... that is 100 million watts
saved!!

I thought it was below 300m, so a few less watts saved!

~350M I believe.

I've always used the rule of thumb that the US population is five times the
UK and don't see a reason to change it!

The UK is less that 1/3 the size of TX, so think of what that means for
population density and why just about nothing can be compared across the
two countries.
