Very beautiful.
I don't envy you your January power bill, though. :o)
Merry Christmas!
Last year a 2-month period around christmas was about the same as my summer air conditioning bill. It isn't terribly bad, but it's not cheap.
A couple of years ago, I replaced every one of my lights with "energy-saving" versions. The old lights used between .34 and .4 amps per 100 lights. The new ones use .2 amps per 100 lights.
I did that MOSTLY because I was running out of power on the existing circuits, before I ran the two new 20-amp circuits to the porch. But I also like to be energy-conscious.
There are new "LED" lights that use 5 times less power, or about .04 amps per 100 lights. They are unfortunately very expensive, although they were also pretty popular this year, having sold out the good colors at lowes (about 10-11 bucks per string of 60-70, vs. the $1.88 per 100 I pay retail for the strings at Target (I often pick up sets at 1/2 or 1/4 price).
This year Target messed up, and most of their colored lights were NOT energy-saving, even though the boxes said they were. That kept me from replacing my blue lights, which are getting quite "white" as the paint chips off. Blue is the worst for this, I'm not sure why. It's why I'd like to at least replace my blue strings with the "LED" lights, which are blue by nature, and don't lose their color.
