Unommim,
What are your qualifications that should make us dismiss what others are saying?
On a micro level, can install a solar roof or solar pannels with battery packs, this would essentially mean charging your EV off of the sun.
On a macro level, solar panel farms can be created. Some businesses with large open roofs are doing it and selling the solar generated power to energy companies.
There will be those that will focus on problems and those that would focus on creating solutions.
But to remain on topic, all major car companies have designated billions in R&D money for EVs. Because Tesla has shown them that its the way to go.
