If you do a search for the number of electric vehicle charging stations in the US, you'll likely get a number somewhere around 160,000. But to better understand what this means, you'll probably want to ask a few follow-up questions:
Are these individual charging ports (for a single vehicle) or are these stations (locations with multiple charging ports)?
How many of these chargers are private versus publicly-accessible?
And how many of these are DC fast, versus just level 2? Level 2 is what most people have at home (I think), whereas DC charging is what you need if you're stopping on the side of the road and need to supercharge your car in 20-30 minutes.
Usually the biggest fear with EVs is range anxiety. We have come to expect that we'll be able to find a gas station when we need it, but, for the most part, we don't yet feel that way about EV charging stations.
So for this concern, the more precise question would be: How many publicly-accessible DC-fast charging stations are there in the US? This is the filter that gives you stations that would be most comparable to how gas stations function today.
The answer, according to the US Department of Energy, is about 10,597 stations and 44,160 charging ports. And according to Bloomberg Green, this puts the US on track to have public fast-charging sites outnumber gas stations in about 8 years.
Of course, it's probably safe to assume that the pace of EV adoption will only increase. And that means that this flip could happen well before 8 years. In my mind, that's soon.
According to Bloomberg Green, there are now at least three car manufacturers -- Tesla, Hyundai-Kia, and GM -- with electric vehicles that (1) have a range greater than 300 miles (480 kilometers) and (2) cost less than the average price of a new vehicle in the US (which is currently around $47,000). This means that we are now approaching price parity:
This is an important adoption milestone, even if it does, at this point, feel totally expected. The International Energy Agency (IEA) is forecasting full price parity by 2030. But in my mind, I'm already done with ICE vehicles. When I bought my current car over 6 years ago, I knew it would be the last internal combustion engine I ever own.
This is an interesting chart from Bloomberg Green comparing some of today's innovations against innovations of the past. At the top of today's innovations are EV batteries, which from 2010-2020, saw annual deployment growth similar to that of US WWII aircrafts. However, when it comes to reducing costs, both EV batteries and solar PV modules come out on top with annual declines approaching almost 20%.
Of course, these probably aren't perfect comparisons. If you look at EV batteries and solar PV modules from 2020 to 2023, their growth rates jump to 72% and 39%, respectively. So who knows if these are the right time slices to be using in order to accurately capture the "key expansion periods." Regardless, it does provide some historical context and it does say something. These are important innovations.
