What is required to move a human from point A to point B on foot, bike, car, train? Bike Engineer Zach Krapfl looks at the environmental footprint of many methods of modern transportation and finds some surprising answers to this question, along with big opportunities for change. A most promising one: People who have changed their main mode of transportation to electric bikes are living healthier, happier, more eco-friendly lives.

Zach is a mechanical and civil engineer based in Paonia, Colorado. He is dedicated to global energy conservation, reduction in fossil fuel consumption, increased energy efficiency and chooses to combine bicycles, light electric vehicles, and appropriate renewable energy technologies as a catalyst for earth lovin’ and a little personal happiness too.
