People say that they would be environmentally friendly if there was an economic incentive to use renewable energy or a more efficient vehicle if one existed.
Well such a vehicle does exist. It is called a bicycle.

But you can't bike far unless you are as fit as Lance Armstrong?
Nope, I know a 65 year old who biked across Canada in about a month.
