    Problem:

    What energy savings could be achieved if an extra 1000 people cycled to the work each day, as opposed to driving?

    Solution:

    According to the statistic data (see for example http://en.wikipedia.org/wiki/Fuel_efficiency_in_transportation), a cyclist riding at 16 km/h needs about 110 kJ/km. This is consistent to a consumed power of
    ( 1)
    where consumed energy per kilometer of riding.

    Remark: The useful power achieved by the rider is much smaller, considering the efficiency of the biomechanical energy conversion; if we estimate, for example:

    then the useful power will be:
    ...

    Solution Summary

    The expert examines energy savings for cycling versus driving.
