Christmas Decorating - a Comparative Remark

Brits decorate their houses much more modestly than Slovenians, or Austrians or Croatians for that matter. Not only the houses, also the city centers of some cities here are modestly but neatly decorated, not excessively like in my home country.

I must admit I like British custom better. Not only is it frequently done with more taste (after my taste at least) but it all consumes much less electricity of course. I wonder if British reluctance to decorate more is grounded on ecological thinking?
