The county has a goal to reduce petroleum use by 20 percent over the next five years, and the Department of General Services plans to expand its electric vehicle fleet. The department now has five battery electric and 10 plug-in hybrid vehicles.
The county already has electric charging stations at several public buildings, including the executive and council offices in downtown Rockville. Private companies have installed some as well, such as at Tower Cos. buildings in Rockville and at The Blairs in Silver Spring.
There are about 250 electric charging stations across Maryland, according to the U.S. Department of Energy, which lists stations on its website.
The number of electric plug-in vehicles sold nationwide increased by 26 percent from 2013 to about 123,000 in 2014, according to industry research site InsideEVs.com. The top sellers were the Nissan Leaf, Chevrolet Volt and Tesla Model S."
