**Electric scooters are twice as efficient as conventional scooters.**

These calculations prove that **electric scooters are twice as efficient as conventional scooters**, even when taking into account the production of electricity for charging the batteries. To travel **one kilometer,** an electric scooter spends **122 Wh**, and a conventional scooter spends **286 Wh **of electricity.

**Petrol scooter:**

- Petrol has a calorific value of 9.5 kWh)/liter
- The fully considered well-to-wheel efficiency of a petrol powered scooter is equal to the energy content of petrol (9.5kWh) minus the refinement & transportation losses (about 33% in India), multiplied by the km per liter.
- So a regular petrol scooter giving 50 km/liter has an efficiency of 1/(9.5kWh divided by (100% minus 33%)) x 50 km/l = 0.97 km/277 Wh

In other words, to travel a distance of 1 km, a petrol scooter must expend ** 286Wh** of energy.

**Electric scooter**

- After observing data from users of electric bikes like Hero electric, Morello Yamasaki and also getting test data from e-bikes like Ather S340, we find that on an average, an electric scooter in Indian road conditions consumes 33Wh/km
- And the power plant efficiency , conversion and transmission losses in electricity in India are 70% or more.
- So an Indian electric scooter @ 33 Wh/km has an efficiency of 1/(3600 divided by (100% minus 70%)) x 10^6 x (1/33) km/Wh = 2.52 km/MJ.
- We then multiply this by the “The full cycle charge efficiency of the electric bike”. Let us take this factor as 90% for ebikes.
- Then the final efficiency is 2.52 x 90% = 2.26 km/277 Wh

In other words, to travel a distance of 1 km, an electric scooter must expend **122 Wh** of energy.

**Conclusion: An electric scooter is more than twice as efficient as an equivalent petrol scooter.**
