Electrical cars are very much promoted for a sustainable future, because they do not rely (directly) on fossil fuels. In the meantime, most of the electricity is produced with fossil fuels, such that electrical cars actually are less efficient from an energy standpoint than when the energy of the fossil fuels are used in a direct way. However, I understand that within a future where all energy is produced in a sustainable way, electricity is 100% green and electrical cars are too.
But, the same argument goes for electrical heating. Electrical heating is very much discouraged, because they are not green. However, creating heat with electricity is actually quite efficient. Now, electrical heating is less efficient than heating directly with fossil fuels; but in a world where all energy is produced in a sustainable way, electrical heating will be 100% green.
So, two times the same story, but a completely different general standpoint. Where am I making an erroneous reasoning?
One possible reason I got come up with myself, is that there is not much room for improvement in electrical heating technology, such that we can just wait with using electrical heating equipment until energy is produced in a sustainable way. On the other hand, it is advantageous to promote electrical cars, because there is much room for technological improvement there.
