Battle lines are being drawn over an attempt to eliminate Georgia’s $5,000 tax credit for electric vehicles. An Alpharetta Republican is re-introducing legislation this year to phase out the credit, one of the most generous in the country. Today, he explains the rationale for his bill in an exclusive column for the AJC. But EV supporters say removal of the credit, used primarily by buyers of the Nissan Leaf, could take the steam out of the electric-car market here. A Nissan Leaf driver and member of the Georgia Public Service Commission outlines why he believes it’s a bad idea to kill the credit.
