Texas Tribune's Katie Galbraith writes --
"..For individuals, the state has done little to encourage electric cars. In his State of the State speech last year, Gov. Rick Perry voiced support for a $5,000 incentive for Texans buying plug-ins in "non-attainment areas," an Environmental Protection Agency designation meaning the areas failed to meet clean-air standards. Houston, Dallas, Fort-Worth and the Beaumont-Port Arthur area make that list. A state Senate bill last year offered a $4,000 subsidy, but it failed to pass, and its sponsor, Sen. Kip Averitt, R-Waco, has since retired. California — home to more than 1,500 electric vehicles, including 500 Teslas, according to a California electric-car group — gives buyers a tax credit of up to $5,000."
