Identifying the leading regional electric vehicle markets in the United States

Electric vehicle sales in the United States represented about 40% of global sales of electrics through 2015. These sales tend to be concentrated in several regions and in particular cities within those regions. Many state and city governments promote electric vehicles with consumer incentives and policy actions. Other groups—including utilities, automakers, nonprofit organizations, and businesses—also encourage electric vehicle purchases with actions such as deployment of charging infrastructure, outreach events, and informational campaigns. Patterns indicating what drives the market are emerging from all of these actions.
