By some measurements, cement production alone is responsible for about 8% of human-caused carbon dioxide emissions every year. And so there is an imperative to find suitable low-carbon alternatives. Here is what is currently happening in the US (via Grist):
On Tuesday, Terra CO2 Technology was picked to receive a $52.6 million federal grant to build a new manufacturing plant just west of Salt Lake City. The company has devised a method that turns common minerals into additives that can help replace Portland cement — a key component in concrete, and one of the most carbon-intensive materials in the world.
In addition to this new facility, the company is set to start construction on its first plant in the Dallas-Fort Worth area:
The project is expected to break ground in January 2025 and begin shipping out materials by late summer 2026, Yearsley said. The facility will be capable of producing up to 240,000 metric tons of SCM [supplementary cementitious materials] per year when completed, or enough to serve roughly half of the local metropolitan market.
And all of this is part of a broader initiative by the US Department of Energy:
The Utah facility is one of 14 projects provisionally selected this week to receive $428 million in total awards from the U.S. Department of Energy’s Office of Manufacturing and Energy Supply Chains. The initiative, which is funded by the Bipartisan Infrastructure Law, aims to accelerate clean energy manufacturing in U.S. communities with decommissioned coal facilities. Officials said the projects are expected to create over 1,900 high-quality jobs across a dozen states.

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.
