Residents who want to learn more about electric vehicles are getting an opportunity to hear from experts and fans about these modes of transportation.
It's part of "National Plug In Day" which hopes to spread the message about the benefits of driving an electric vehicle.
David Gebert, a member of TEVA2, said that despite its bumpy history in the United States, electric vehicles appear to be gaining real traction now.
"Sales are going up," he said. "By July we had equal the sales of 2012, and so we are going to at least double (them) this year if that maintains."
The estimated number of plug-in electric cars on the road in the U.S. is fewer than 150,000. That is a small fraction compared to more than 200,000,000 cars that are fueled by gasoline, but Gebert said the trends look promising.
A new electric vehicle made by BMW is scheduled to be present at the show.
Tucson Plugs In will take place on Sunday, Sept. 29 from 9 a.m. to 1 p.m. at the new Bookman's Sports Exchange located on 3330 E. Speedway Blvd.
