I'm not sure about France, but it's rare to have air con in the UK because the summers aren't hot enough :) I think a lot of Europe is similar in this regard (with the exception being the south).
Even if France does have a reasonable number of air con units installed, I would expect energy consumption to be higher in the winter due to shorter days etc. It would be good to see statistics though.
