perhaps we need to look a bit further down the chain at transport itself. we are moving over large distances which will always require large volumes of energy in any form. i drive 15 km to work. i could ride but i´d need a lot longer than the 15 mins it takes to drive there. i flew roundabout from australia to iceland in 2 days. i could walk and take the boat but how long would that take? the boat would still require energy and i still need food for that time. to me it´s a simple extension of the concept of converting one form of energy to another and in the conversion you can never gain energy from nothing and there will always be waste.

physics of a bicycle, isn't it remarkable?
