> How is biking better than walking? Glad you asked. Biking has an energy efficiency of around 99%. Very little of the effort you put into biking ends up as waste heat. Walking, on the other hand, has a much lower energy efficiency. You are putting much more effort overcoming and generating friction as you move your legs. You are also doing it for a longer period of time since you are going slower. It's one of my favorite counterintuitive facts. > I would guess what I do (in the UK) is uncommon in the US And that's for sure. In almost every US city if you want to do anything, you are driving. Where I'm at, everything is at least 10mi from my home. That racks up the miles pretty quickly.
