I switched to LED bulbs when the price came down. We bought 6 Philips bulbs for $1 each in a special offer at Home Depot. They were to last 10 years but “only” lasted 6 years. The energy they consume is a tiny fraction of incandescent bulbs. With traditional Xmas decorations outside and inside our January power bill usually went through the roof! With all LED lighting we hardly notice the difference.
The decorations in “Christmas Vacation” with Chevy Chase must have needed special wiring and a power board. A 100 amp service would not do it!
The only place we still have an incandescent bulb is in a clothes closet, used 5 minutes per day; it is now 10 years old and when it goes it will be replaced with an LED one that will outlast me.
Ask your friend what his Kilowatt Hour consumption is per year. And compare it with yours.
Our house is a 4 bedroom, 3 bath model and we have 2 fridges, 2 freezers, 2 microwaves. 3 TVs, 3 computers, and numerous other electrical gadgets. Kitchen range is a Whirlpool electric range.
Our yearly consumption is about 9000 KWHs. I measure the consumption of various gadgets. Our large screen 2008 Plasma TV uses 800 KWHs per year, the greediest thing we own. It will be replaced next year with an LED model which uses a lot less.
Before all these efficient gadgets, in the 70s, our consumption was 14,000 kwhs per year.
