The science shows EVs produce less CO2 emissions in their lifetime.
But even better news, EVs have the ability to take energy from ANY source. . . So the transition to green energy options is easier. Wind(mostly produced at night) becomes more and more economical.
Lastly, the massive improvement in battery technology is also amazing.
If you look at the science
#1 EVs are already cleaner than ICE.
#2. EVs have a lot more potential and possibilities.
So tell him "This isn't political" and cut straight to the science."
