Kidô Senshi Gundam 00 (2007)

In the distant future, mankind has used up all of its fossil fuels, forcing them to turn to Solar Power as an alternate energy source. As a result, this causes a rift to form between richer and poorer nations, eventually leading to war. In the midst of this conflict, a mysterious military group known as "Celestial Being" aims to use force to bring peace to the world, by using special humanoid weapons known as Gundams.
