Mark, That is kind of naive, or not resulting from careful thought - "cleanliness" of any electric use depends on the power generating source.
I have 6kW of solar at home - pretty clean. If I charged the light EV pack with a gas generator that would be pretty stinky. Grid power around here is primarily NG from modern plants, so... you can argue about clean there many ways. I could probably cobble together a wood gas generator/generator that would stink, but be carbon neutral. Then there are all the other options. Light EVs are, if nothing, cheap for low income folks, they help the sedentary wealthy get some exercise on short trips - just like the Vermont people noted in recent posts. Light EVs don't waste as much energy because they generally don't go very fast - anything over 12mph has an air drag penalty and 80mph is very inefficient in comparison whatever the source or vehicle. Air drag is the predominant energy wasting pathway. Light EVs make a lot more sense in terms of material efficiency as they don't have to resort to titanium, and aluminum to be lightweight (easily made from recovered scarp and recycled parts). If you want to do a dust to dust comparison. A human is incredibly efficient if you can get sufficient distance and trip time. A few meals of beans and greens will get you a couple hundred miles if you are a hearty and practiced rider. I suspect that is how the vast majority of the millions of EV bike owners are doing it. Someone recently quoted there are 126 million light EVs, bikes scooters, and so on. You can discount the biological miles as not pertinent, but I think the pedal/EV hybrid is a very worth design. Far cleaner than other alternatives for most power sources and use cases. On Sat, Aug 22, 2015 at 8:35 PM, Mark Abramowitz via EV <ev@lists.evdl.org> wrote: > Aren't EV miles *dirtier* for bikes?
