A Green Year (and Airconditioners)

I figured that January 1 is a good time to start reading the book The Green Year. It's basically a diary-format book with a tip per day of things we can do to be green.


One of the tips i read today was about airconditioners. (Yes, i'm kinda cheating by reading more than a day at a time - it's a library book, so i don't have all year). Anyway, the tip: Clean the filter - easy airflow makes the unit much more efficient.

Oh, and a couple of things about the book: some of the tips don't specifically relate to greenhouse emissions (it's more about being green in general) and coming from america, a lot of numbers are in pounds, gallons and degrees Fahrenheit.
