President Barack Obama’s goal of putting 1 million electric vehicles on American roads by 2015 is achievable, according to a government report cited by the Washington Post newspaper.

The administration report contradicts the findings of an expert panel, which said last week the target could not be achieved.

According to the Post, the report, which is scheduled for release Tuesday, found that automakers are prepared to build 1.2 million plug-in vehicles by 2015.

The newspaper said the opposing reports both count electric-car production forecasts from automakers, but use different numbers.
