Electric cars only 2030?Watch
additionally what an electric car is yet to be defined
BEV battery electric vehicle
BEV+RE battery electric vehicle + range extender
FCEV fuel cell electric vehicle
HEV hybrid electric vehicle
PHEV plug-in hybrid electric vehicle
MHEV mild hybrid electric vehicle
by 2030 we will likely see all consumer vehicle sales electrified in some manor but probably not limited to BEV, instead we will see a range of solutions adopted for different vehicle classifications.
Given the energy density of typical lithium based electrochemical storage and the sizes of battery needed in large cars with higher load cycle requirements pushing required battery sizes to like 100 kW/h it would requires the vehicles to travel roughly 60,000 miles just to break even with a traditional ICE equivalent and that assumes the grid is 100% green which is also far from true.
Additionally we have seen the emergence of alternative combustion techniques increasing the efficiency of traditional combustion engines, and the work being done to promote biofuels such as high ethanol blends, hydrogen, biogases etc. is just taking off which could lead high level net carbon reductions in road transport.
EVs make sense in small class A & B (some class C) cars but are definitely not the best for the environment across the board that is a misnomer. But having a pragmatic discussion about all types of vehicles doesn't suit the agenda of the day.
