What is the future of electric vehicles, and will it be really an alternative?

While there are seeds of truth in the other answers, they miss the point of electric vehicles.

1. Battery costs are dropping by about 20% a year every year. They are already at $100/kWh in 2020, and by 2023 BEV will be cheaper to buy and cheaper to operate than an ICEV.
2. ICEV will have over 2,000 moving parts in engine, transmission and power train while a BEV may have less than 30. That means the BEV will be cheaper to maintain over time.
3. The cost to charge a BEV is about one fifth the amount needed to fill the tank of an ICEV for the same range.
4. New charging stations are going in very fast, and if there isn’t one near you now, there will be very soon. So you can easily travel cross country and never run out of battery.
5. Because a BEV will be cheaper to buy and cheaper to maintain and cheaper to run, by 2025 half of all new cars will be electric, either BEV or hybrid. And by 2030, half of all cars on the road will be electric. Finally, by 2040, 90% of all cars on the road will be electric.
