As the nuclear disasters of Fukushima and Chernobyl ruined the life of millions, Greenpeace Hungary called attention to the legacies of the catastrophes and called for a change.
An ionizing radiation symbol with solar lamps is displayed, and then gradually transforms into a wind turbine sign to symbolise that a safe and sustainable future is only provided by renewables.

The signs are placed on Heroes' Square, one of the most prominent squares in downtown Budapest.
