bastianallgeier, 
I’m always amazed by how poor the efficiency of fossile energy really is.
- A coal plant has an efficiency of around 40%
- A gas plant can get up to around 60%
- A combustion engine car can only translate up to around 25% into motion
Most of the rest is wasted as heat.
Getting rid of fossile fuels by electrifying transport and switching to renewables automatically leads to huge energy savings.
