The unchecked use of fossil fuels has brought the world to its knees. Make no mistake about it.  The world is facing an existential crisis that doesn't brook any delay in its solving. The cars we drive have unfortunately become a symbol of all that is wrong with the way we have been interacting with our environment for more than a century. When the automotive industry was in its infancy there were all kinds of technologies being relied upon to power the vehicles being manufactured- steam based, petroleum fuel based and electric. That all automobiles came to run on petroleum by products was the outcome of a lot of reasons. 

Perhaps, its time to make a complete move to electric cars. After all the first one of these was with us over a hundred and twenty years ago.
