> To travel one kilometre by bike requires approximately 5-15 watt-hours (w-h) of energy, while the same distance requires 15-20 w-h by foot, 30-40 w-h by train, and over 400 w-h in a singly occupied car.

Since the rise in popularity of electric cars 400wh/km is actually quite high.

Most electric vehicles are rated city/highway 15/20kwh/100km (150 w-h/km / 200 w-h/km)
