An old saying coined mostly by science fiction writers goes like this "There ain't no such thing as a free lunch". I find that saying to hold true in every aspect of what we do in our daily lives. Just like over unity, from what we know of physics in our little spectrum of knowledge of the universe you cannot get something from nothing nor can you create more of anything out of less than what is already there.
BEVs are being touted as the end all saving grace of vehicles, but nothing could be further than the truth than the purposeful omission of the cost of energy to produce them, the added strain on natural recourses to produce them.
Hybrids are as has been mentioned probably the better of the 2 worlds. However, from a purely economic means of going to town and back. If for instance you don't need anything more than transportation if you had a duel chargeable Hybrid or even a BEV that you could plug in to recharge the battery when it is parked at your home from solar panels instead of being charged from the grid once the initial cost outlay was covered from miles driven not having to pay the utility company for your electricity you would realize at net savings of cash, Driving the duel chargeable hybrid sensibly you might not even have to run the engine very much at all.
But none of anyof this will do a thing to save the planet as they like to say, unless you maintain and keep the vehicle for its full life cycle. This trading for new every year or even every 5 years will do nothing but continue the cycle of waste.
I bet my 30-year-old diesel pickup that gets around 20 MPG is as green if not greener than most vehicles sold within the past 5 years will ever be if they are not kept on the road for at least 15 years, assuming any of the plastic laden electronically overburdened pieces of junk will last that long
