ev main purpose is not I repeat not to make it more environmental better. its just serve as an alternative to fossil fuel .
our world current way of producing electricity is still harmful to the environment.
unless only renewable energy such as solar panels is massy adopted.
and thirdly I see those ppl installing solar in their house and talks about money save or money earn ( if can ) its just running round and round 10 year cycle period.
all also talked roi here and there but after 10 years. they repeat the same thing. that is invest again in whatever form and wait another 10 years.
