zyggy is a green/eco energy portal that finds customers the best fit green energy rate. As such, it embodies a young, fun, transparent, socially responsible brand.
As laid out by the "example logo", the font should be sans-serif, young and playful, which is not to say immature. The logo needs to convey a transparent, innovative, environmental spirit teeming with dynamism. It defines a business niche of huge potential and significance. So much for the "feel".
The more specific requirement is that the logo establish the atlantic puffin as our mascot and symbol of identification with zyggy (http://en.wikipedia.org/wiki/Atlantic_Puffin). The puffin should look friendly, perhaps in flight or in some way be active. We would like to see different positions/angles. It should be centered to a backdrop of nature in which the key sources of renewable energy are just subtly visible (i.e. solar, wind, water, biomass). It needs to be a stylistically fitting amalgamation of Puffin&RenewableEnergy countryside (see "feel") but not look like a cartoon if possible. It should be placed to the right of the name, as shown in the example logo. Also, underneath "zyggy" it should say the slogan "Das Ökostromportal", probably in an identical or very similar font.
Even though they're is no archetypal customer, the brand probably most speaks to 25-45 year old females and males with an informed, highly educated background. Their typical concerns are caring for the environment, family and making an impact.
