In addition,
embodied energy calculations are almost never done conclusively, really looking at EVERY material that goes into a building, and the localised variations in the procurement chain (eg aluminium in NZ is produced with 100 % hydro electricity), but rather picking and choosing structure, insulation and whatever else is de rigueur.
The accuracy is somewhat debatable, since
the embodied energy calculation is user generated and sources of information on power consumption in various phases of a product's lifecycle are sketchy at best.
Not exact matches
Embodied energy and carbon footprint calculations are a good start, but it would be nice if the product itself came with a True Cost number or rating, like the nutritional information on a cereal box or the Energy Star rating on a refrige

@ Michael (# 11): I made a
calculation of the
embodied energy of an electric car battery here (about halfway the article): http://www.lowtechmagazine.com/2010/05/the-status-quo-of-electric-cars-better-batteries-same-range.html
This means that the annualized contribution of
embodied emissions to our
calculation should be about half that of the operating
energy.
