The Nissan Leaf has achieved the 10,000-sale milestone in America.

The Nissan Leaf has achieved 10,000 U.S. sales, a sign that EVs are beginning to be considered by more consumers as a viable alternative to traditional gas-powered vehicles.

The Leaf quietly achieved its 10,000th sale during the Detroit show last week, according to Autobloggreen. Nissan's EV first hit the market in December 2010 and is not yet on sale in all 50 states, though that milestone will occur in March.

"From a Leaf perspective, 2011 was a great year and very positive for the company," said Brendan Jones, Nissan Leaf Marketing and Sales Strategist for Nissan North America. "[10,000 sales] is more EVs than have been sold in the United States -- and 20,000 globally -- than all the other OEMs combined throughout the world. So that's an outstanding achievement."

The Leaf will face increased competition for the hearts and checkbooks of green-focused buyers in 2012 from new rivals like the Ford Focus Electric and Honda Fit EV.
