Activists from Greenpeace Africa drive three dumper trucks filled with coal to the front of the Eskom Megawatt Park to unload five tonnes of the rock outside their offices in Johannesburg. Effectively blocking one of the entrances to the building with the coal. The activists also hold banners calling on Eskom to 'clean up it's act', to "Stop Coal", to end their usage of the outdated fossil fuel; to publicly demand that Eskom stops the construction of the Kusile coal-fired power station and and shift investments to large-scale renewable energy projects.
