Nosing around on the net (boredom) I found this ruling from the UK Advertising Standards authority. http://www.asa.org.uk/Rulings/Adjudications/2012/2/Blue-Carbon-Ltd/SHP_ADJ_157911.aspx which relates to this thread from a while back http://cr4.globalspec.com/thread/87790
One of the contributors mentioned Blue Carbon Ltd.
Thought it may be of interest to those who like me don't believe most of the electrical energy saving rip offs.
