Energy system transformation means the conversion of all types of energy use from fossil and nuclear energy sources to renewable energies.
The goal is a CO2-free energy generation.
This includes not only power generation, but also the provision of clean energy for transport, for heating and cooling buildings and for industrial processes. In addition, the fossil raw materials commonly used in industry must be replaced by CO2-free processes. For example, it is possible to convert chemistry, which is still largely based on fossil crude oil, but it requires a great deal of effort and energy.
