Earlier this summer,  Greenpeace organized a contest encouraging people all around the globe to redesign BP’s logo after the Gulf oil spill catastrophe. A week before the end of this competition and announcement of the winner, the global environmental organization launched another creative challenge at jovoto, inviting internet users to find a new key visual to support the message «Renewable energy can cover 100% of our power requirements by 2050» for its upcoming anti-nuclear power campaign in Germany.
