I do agree with the plans being put forth by all leading Automakers. But I am wondering how the transition is possible in the next 10 years especially given that oil consumption was very progressive and there were a natural supply and demand spread in the last 100 years. In a way, oil became a sustainable & affordable source in the world, and the extraction & refining was cheaper. When it comes to electric vehicles, more than a renewable source for power, I think battery supply will become critical. Is it possible to achieve that level of supply to 1 billion vehicles in the world?. Will we have a sustainable supply (esp raw input for batteries) in this particular space without huge implication on the price in the next 10-20 years?. I am hoping you may have an insight.
