National Drive Electric Week

113 cities and counting. That's not bad for an event that started with just 29 four years ago.

Yes, next month, from September 15-21, National Drive Electric Week will take place in over 100 locations around the country (with some in Canada and Mexico). The celebration of electric vehicles is organized by Plug In America, the Sierra Club and the Electric Auto Association. The idea is to get people who've never driven an EV to test them out, talk to current owners and spread the word online. You can follow along on Twitter starting now with hashtag #NDEW2014 and find an event near you here.

Last year, the big announcement tied to the celebratory weekend (it's been expanded this year to a full week) was that Nissan had sold a total of 35,000 Leafs in the US. With almost 60,000 sold now (57,877 as of the end of July), it's been a good year for the world's most popular EV.
