No states ranked in the top bracket for readiness, and the top three states crept into the second rating bracket of EV accepted. States that ranked highest are not classified as realistic environments for EV transition but are merely better prepared than others. These rankings incorporate the fluidity of the transition to electric vehicles and growth of the market and will shift as the EV landscape evolves.

Climate suitability plays a significant role in determining EV readiness. Cold environments are not yet ideal for EV operation due to the impact low temperatures have on driving range, charging speed and duration. On average, states that experience colder weather need to take additional measures in their EV transition efforts to secure a successful transition. European countries like Norway have proven that cold climates are not impossible to overcome, but proactive measures must be taken to ensure EV readiness.

For the purpose of this index, only public charging was assessed. While it’s promising to see federal government commitments, such as the planned $7.5 billion to accelerate EV adoption from the Infrastructure Bill, developing this network of chargers will likely take years and make public-only charging solutions impractical.
