Assemblyman Phil Ting, a San Francisco Democrat, thinks that is not enough.

To induce drivers to purchase electric vehicles, California Considers a $3 Billion Electric-Car Rebate Push sponsored by Ting.

The bill has passed the state Assembly and is advancing in the state Senate, which is expected to take up the bill once it clears a final committee next month. Gov. Jerry Brown has set ambitious goals for zero-emissions vehicles; he hasn't said whether he would sign this bill.

A $5,000 tax credit in Georgia helped the state become the second-largest electric vehicles market in the U.S. after California until the state tax credit was eliminated in July 2015, according to Edmunds, a website that tracks automotive sales. After the change, sales in Georgia fell to 2% of all U.S. electric vehicles sold in 2016 from 17% in 2014, according to the site.
