I was at the PlugIn 2010 conference last week... the conference focuses on "plug in vehicles" primarily automobiles and trucks. Not bicycles or motorcycles, unfortunately. Anyway it's very interesting and the attendees are industry and government and business leaders, as well as journalists and other observers.
A repeated question many were discussing is - 10 yrs ago was the previous wave of electric vehicle adoption. This time it's much bigger. Why?
I wrote up a lot of reasons that were stated both at the conference and in some questions I tossed out on twitter yesterday afternoon.
10 years ago all the reasons to electrify weren't quite so apparent as they are today.
The technology has improved a lot over the last 10 years. One example is the electric racing motorcycles I've been following this year but it's much more than that.
Tesla Motors proved that electric vehicles can be fast, sexy, and capable.
The internet enabled online communities (like this one) to exist for information sharing (as we do) and mutual support.
Fleet owners have more tools at their disposal to understand the costs and recognize that electrification can pay off quickly.
