Yesterday, we talked about whether replacing old but perfectly good and working appliances with new, more energy-efficient models made sense (see here). We crunched numbers to do with the “embodied energy” and environmental impact of the manufacture of the new appliances versus the amount of energy potentially saved.

When to turf out an old appliance for the energy efficient model–The New York Times is wrong [Except that I made a big mistake in my calculations so they may be right]
[This just in on May 13: I majorly screwed up yesterday’s calculations causing the embodied energies of the steel to be over-estimated by a factor of five and therefore throwing this whole post off. Ugh. So sorry. The argument is not as straightforward as I had hoped and I will have to look into it more for the […]
