Broadening the Premise of the Discussion
So-called "logical" arguments have a certain power to persuade, or perhaps compel, people. However, such logical arguments
often involve
isolating and developing specific aspects of reality. For example, as a counterargument against electric vehicles, there is the argument that
generating electricity with fossil fuels to charge and power the car
when considering efficiency during power generation and other factors
is less efficient than powering a car directly with gasoline.
Admittedly, the thermal efficiency during power generation is around 40%. Furthermore, even if the motor efficiency is 95%, when considering transmission and distribution efficiency as well as charging losses, this argument appears to be correct.
However,
electricity allows for more precise control
and enables more effective use of energy.
There is a counterargument that states this. In fact, without such advantages, hybrid cars would not be viable. Additionally, there are examples of diesel locomotives on railways that carry generators to drive motors.
Now, here is another perspective: heating. While it is said that the thermal efficiency of a gasoline engine is around 40%, a portion of the waste heat from that loss can be used for heating. On the other hand, an electric vehicle requires electricity for heating as well. Considering this,
is an electric vehicle truly more efficient?
This discussion needs to be conducted while broadening our perspective.
