Can Indias 50% vehicles be Electric by 2030?RationaleIndia does not have much oilOur oil imports rising continuously: hurts Indian economyNo solution in site in short, medium or long-termOur cities and towns are highly congestedHighly polluting urban India

Cost of mechanical (IC Engine) drive-train (MDT) goes up year after yearElectrical drive-train without batteries (EDT) cost goes down year after year (R&D, Moores law and SW)Crosses each other and Gap increase year after yearCost of Fuel (Petrol) per Km increases every yearTotal cost of battery per Km (life-time depreciation, interest, maintenance and charging of battery) keeps coming down Crossed over recently and gap likely to only accelerateDC Powered Smart-city*
