The article focuses on the poor showing of the Chevy Volt relative to other vehicles.  

But to the folks here, the most important thing is probably this note:

"

The fully electric Nissan Leaf ranked second among all 2011 model year cars on the same list. First place went to the compressed natural gas powered Honda Civic GX.

The 2011 Chevy Volt ranked 12th in ACEEE's list.

Vehicles are ranked according to a "Green Score," factoring fuel economy and emissions, including emissions from electric power plants. The relative impact of a vehicle's manufacture and disposal, based on the car's weight, was also considered."
