I agree. I post you a new version right now. And i think it looks better. (The capital E is actualy like this in the font I've used. But sometimes you have to do some adjustments :-)
I've changed the font so it's more powerful. And I think it's better when you say ELECTRIC + ZERO CO2 in green. That's the simple and clear concept. Then you're giving the right signal to people concerned about green issues and for creating a world with zero emissions.
