The number of public EV charging stations in the U.S. has seen an exponential increase over the past decade. Between 2007, when there were only 139 public EV charging stations across the country, and 2023, this number skyrocketed to over 64,000. This rapid growth is more than double the number of stations in 2020 and three times the number in 2018, illustrating a significant push to make EVs more practical and viable for consumers. The dramatic increase in EV charging infrastructure underscores the impact of sustained investments and governmental policies aimed at promoting electric vehicles.
The growth of EV infrastructure is not only a result of increased government spending but also the participation of private companies. These combined efforts have made EV charging more accessible to a broader range of consumers, addressing one of the main barriers to EV adoption. As the density of charging stations grows, so does the practicality of owning an electric vehicle. Consequently, more drivers are considering EVs as a viable alternative to traditional gasoline-powered cars, further fueling the market and expanding charging needs.
Federal Funding and Legislative Measures
A critical driver of this expansion has been federal funding under the Biden administration. Key legislative measures, such as the 2021 Bipartisan Infrastructure Law (BIL) and the 2022 Inflation Reduction Act (IRA), have injected billions of dollars into developing the EV charging network. In 2021 alone, over 17,700 public stations were added following the allocation of $7.5 billion from the BIL. These legislative efforts have significantly accelerated the growth of the charging network, making it more comprehensive and accessible to EV owners nationwide.
The BIL and IRA have provided the financial backbone necessary to build a nationwide network of charging stations capable of supporting the growing number of EVs. These investments cover a wide range of projects, from installing fast chargers in high-traffic urban centers to placing strategically located stations in rural areas to bridge the accessibility gap. Furthermore, state and local governments have been major beneficiaries of federal grants, which have enabled them to tailor EV infrastructure projects to meet specific regional needs, thus enhancing the overall effectiveness of these federal initiatives.
The Role of Private Investment
Tesla’s Dominance in the Market
Tesla, a leader in the EV market, plays a significant role in owning and operating much of the EV infrastructure. In 2022, according to the International Energy Agency’s Global EV outlook, nearly 3 in 5 of the 22,000 public fast chargers in the U.S. were Tesla superchargers. This dominance underscores the importance of private investment in the expansion of EV charging stations. As a pioneer in the EV space, Tesla has not only pushed the boundaries of electric vehicle capabilities but has also driven the growth of the necessary infrastructure to support these vehicles.
Tesla’s commitment to expanding its supercharger network has had a ripple effect across the industry.

Geographical Distribution and Accessibility
Urban vs. Rural Access
Mapping the geographical distribution of EV charging infrastructure reveals that most U.S. counties now have public EV chargers. However, there is a significant disparity in access between urban and rural areas. About 64% of Americans live within two miles of a public charging station, with urban residents having considerably better access compared to their suburban and rural counterparts. This uneven distribution poses a challenge for nationwide EV adoption, as access to convenient and reliable charging is crucial for all users, regardless of their location.
Urban areas have seen a concentration of charging stations due to the higher population density and greater demand for public charging solutions. As a result, urban residents typically experience shorter travel distances to find a charger, facilitating EV ownership. In contrast, rural areas lag in infrastructure development, often requiring residents to travel long distances to reach the nearest charging station. This unequal access can hinder the growth of EV adoption in rural regions, where the convenience and availability of charging options are critical factors.
Leading States and Counties
Counties in California, Washington, and Massachusetts lead with over 1,000 public stations each. This higher concentration of charging stations correlates with higher adoption rates of electric and hybrid vehicles within these areas. Nevertheless, targeted investments are needed to ensure a more uniform distribution of charging stations nationwide. Addressing the discrepancies between urban and rural access requires strategic planning and financing from both public and private sectors to overcome the logistical and financial barriers that hinder infrastructure development in less densely populated areas.
The leading states have set a successful precedent by demonstrating how comprehensive EV infrastructure can drive higher adoption rates. By investing in a balanced mix of urban and rural projects, these states have created a more accessible network that supports a diverse range of EV users. The lessons learned from these pioneering regions can inform policy decisions and investment strategies, helping other states to develop more evenly distributed and effective charging networks.
Case Study: Mississippi
Current State of EV Infrastructure
Mississippi serves as a microcosm for examining statewide EV infrastructure progress and challenges. As of 2023, only 0.2% of cars on Mississippi roads were electric or plug-in hybrids. The state housed 216 charging stations by November 2024, supported by $87.3 million in federal grants towards clean transportation in the past three years. This allocation translates to roughly $30 per Mississippian and highlights the relative infancy of EV adoption in the state compared to more developed markets. The limited number of charging stations in Mississippi poses challenges for current and prospective EV owners, who may be deterred by the lack of accessible charging options.
Despite the lower adoption rates, the investments made in Mississippi are laying the groundwork for future growth.
