Greenpeace activists protest at an Apple reseller in São Paulo. An activist is wearing a sun costume to represent renewable energy. The activity is part of a global day of action at stores around the world. Greenpeace played off Apple’s “genius bars” by setting up their own “Supergenius bars," where people were encouraged to take part in the campaign. Greenpeace is calling on Apple to power its massive data centres with renewable energy instead of coal.
