For one trip, an e-bike uses 0.08 kWh and takes 28 min, a bus averages 0.18 kWh per passenger and takes 22 min, and a car averages 0.65 kWh per passenger and takes 18 min. Evaluate which is best.

Question

Accepted Answer

The e-bike has lowest direct energy use, the car is fastest, and the bus is intermediate; 'best' depends on safety, access, occupancy, weather and lifecycle boundaries, so state a criterion before concluding. Compare the supplied like-for-like per-passenger trip energy values. Identify the time trade-off: car 18 min, bus 22 min, e-bike 28 min. Question occupancy averages, electricity source, manufacturing boundary, route safety and accessibility. Give a conditional conclusion, such as e-bike for minimum operational energy when feasible.
