Asti,
Like the typeface you have used for RE-AMP.
But the arrows working in a continuous circle look cool, but don't quite convey our core message.
In the original logo, the black arrows that point down represent pollutants and inefficencies and they are "overcome" by the green arrows that point up (rcleanr, enewable energy sources).
So perhaps you can experiment some more. Remember, this logo represents an area where hundreds of organizations are coming together to fight for renewable energy. So collaboration is a theme you might want to explore.
Thanks.
