The event that began five years ago as National Plug-In Day is now entering its second year as National Drive Electric Week, and organizers say this year's will be bigger than ever.
Every year, advocacy group Plug-In America collaborates with the Sierra Club, the Electric Auto Association, and various smaller local groups to host a variety of activities that raise awareness of plug-in cars.
The week-long event is comprised of scores of individual electric-car rallies, demonstrations, and other gatherings, both in the U.S. and abroad.
Last year's National Drive Electric Week set attendance records, but organizers believe they will be broken this year.
More than 170 events in 165 cities are already planned for National Drive Electric Week 2015, which will be held September 12 to 20.
They'll take place in 39 U.S. states, along with Canada and Hong Kong.
