Willa Cather Knows Electric Cars?

I'm reading Willa Cather's One of Ours-- which was published in 1922-- and without any fanfare, in a line of description about the town miller's wife, Cather wrote "she dressed well, came to town often in her electric car, and was always ready to work for the church or public library"-- which makes me wonder . . . if an electric car was a commonplace item in turn of the century Nebraska, then: who killed it?
