Week 1 Challenge

Electric vehicles attracted widespread interest because of their ability to reduce energy consumptions and emissions.

Conventional gasoline vehicles only convert about 17%-21% of the energy stored in gasoline to power at the wheels. An electric motor is typically 85%-90% efficient.

Electric motor converts electricity to motion three times more efficiently, in energy terms than internal combustion engine.

For direct comparability in performance, the car battery has to be forty times bigger in volume than the gasoline tank.
