Concept based on plug, visually connected to leaf, as a symbol of green theme. Circle design is to represent wheel, motion and plug socket. Legibility (at small or big sizes) is ensured by using simple, yet modern and readable fonts. Logo works at any sizes or colour modes (black-white, inverted or single colour). Logo can be mirrored or rotated without loosing its relevance and memorability.
