Warm sweaters day... #warmetruiendag

@Warmetruiendag

Today we have warm sweaters day in the Netherlands.
Put your heating min 1 degree lower ( I chose -3), 
Wear a warm sweater, and save 6% energy per degree...and therefore 6% CO 2 emissions....

Well...I'm in for it... Well, come on and join me....Warm sweaters day
