Electricity consumption saves water at midpoint
Posted: 04 Aug 2016 16:14
Hello fellow openLCA people!
I have a question concerning the effect electricity consumption has on water depletion in the LCIA because I find it quite weird:
I am using openLCA 1.5.0 and the elcd databse 3.0. In my model the use of any electricity flow from the elcd database is saving water at the midpoint level. I made a very simple model to show the effect.
If I use 32 kWh to produce the product X, 136m^3 of water are saved - how can that be? To me this makes no sense..
I used several of the energy mix flows to check for differences, e.g. this one: Electricity Mix, consumption mix, at consumer, AC, 115-220V.
Using ReCiPe or ILCD impact assessmnet method at midpoint gives me this "positive" impact, i.e. that electricity consumption saves water.
Does anybody have an idea why that is the case?
Thank you :-)
