The energy mix is a group of different primary energy sources from which secondary energy for direct use - usually electricity - is produced. Primary energy in the form of fossil fuels is nowadays still mostly used directly for motor-driven vehicles, i.e. transport. Further energy conversion of the co-produced waste heat after burning is not possible.
