200 -- amount of terawatt-hours saved annually by the gradual switch to more efficient refrigerators in the USA (see chart above).
80 -- roughly the number of extra power plants that the USA would need without these efficiency improvements.
7 -- that's the percentage of GDP that is spent on energy in the USA. Energy intensity per unit of GDP has been decreasing about about 2% per year in the USA, and about 1.5% per year overall on the planet.

Wow. What a great way to show how everyone doing their little part really adds up. Now I just need to convince the parents to get rid of the second fridge, or at least replace it soon with a smaller and more efficient one...
Great Statistic. I'm going to share this one for sure. Thanks for the good post.
My wife thought we should keep our old fridge and put it in the basement to use with our bar.
"Why?" I asked. "For most of the year we can just keep the drinks under the porch and they'll be plenty cold. And they've got mini fridges at CostCo for like $100."
