An extinguished wood fire, oil barrel and a solar panel are arranged rising on a staircase. The work presents the phases of man’s energy extraction from nature. Gone are the pre-industrial days with the open wood fire on the left. We are in the middle of the fossil phase and need to enter renewable energy production on the right because of the acute climate crisis. Through our use of fossil fuels, we have caused a climate crisis that threatens humanity. The transformation consists of quickly replacing fossil energy production with renewable energy.
