I'm not counting on my cost of electricity staying the same in perpetuity. If one frig costs a hundred more but is that much more efficient the difference is paid in eight years or less and after that the savings are gravy.
My example was for a price difference of about $300 and it wasn't apples to apples.
Now you also have to take into account the life span of a product. In this case 8-14 years. I think 8 years to get even for a $100 is meaningless in this example. »repair2000.com/lifespan.html Ya, I usually get a longer life out of my products too but this is what people think.
Basically I'm just saying it takes a long time to make up a big price difference just for some energy efficiency.
My comparison was to show the range in efficiency, I should have spent more time looking for two apples to compare.
The OP's original unit lasted 40 years. The frig in our kitchen was made in Sept 1990. I just extended the life of an old range with a $30 heating element. Interesting that $100 is meaningless to you. CFL light bulbs and driving slower probably aren't worth the savings to you and the environment either, eh?
