Hi Satto,
first of all my compliments. Your proposals are allways unique, show your own distinctive "handwriting".
The Slogan would cause trouble or wrong associations close to the Dutch border here.... ;-)
Green also reminds a little bit too much on menthol cigarettes (as the choosen colours including menthol green do as well).
We also believe that the health aspect works stronger than for instance the electricity aspect or -as in your case- the "green" aspect.
One negative, unfortunatly quite visible aspect: watch out for the "t", it looks like a cross on a tomb. :-)
