The transportation sector is responsible for 28% of greenhouse gas (GHG) emissions in the United States and has recently overtaken the electric power sector as the largest source of GHG emissions in the country. Because they generate no tailpipe emissions, electric vehicles (EVs) can play a critical role in achieving significant GHG emissions reductions, meeting aggressive climate goals and reducing localized air pollution. If charged with clean electricity, EVs can be almost entirely zero emission. Existing literature demonstrates that electrification can lead to reductions in light-duty GHG emissions of 36 to 50% by 2050. For heavy-duty vehicles, this projected reduction can range from 22 to 43% by 2050.

The above text comes from the report, “The State Transportation Electrification Scorecard” from The American Council for an Energy-Efficient Economy (ACEEE). This report ranks states’ efforts—identifying those that have taken comprehensive steps to reduce barriers and others that are just starting. Every state can step up to enable equitable, electrified transportation for all.

This post is largely based on the results and recommendations of this report, and some related information.

What's interesting is how much less segmented we'll see these two industries in the future as they get interconnected because of the push for electrification

Actually, many industries will be electrified. 

I'm planning to post "I Like Smoke & Lightning, Heavy Metal Thunder, Part 2" in mid-December where I'm revisiting an old post from 2018 for a major industry that is moving heavily toward electrification.  below is the link to Part 1.

John, The Electrification of each vehicle makes a big difference. Buses are also in the truck category. The reduce maintenance will help pay for a lot of it. REGENerative braking is also a big plug with these large vehicles. The stats on the Tesla Semi make it look like a great choice. Charging of fleets Off Peak will be another great savings. Most are starting to come out in 2022 so I will be watching the progress we will be making very soon.

    In Arizona many busses have changed to NG and CNG. That doesn't really do much for GHG but they feel better. We also have some light rail and that has been very good.

Hi Jim, thanks for the comment.

There are lots of choices for buses right now. See the paper linked below:

Trucks, not so much, and most are repurposed additional trucks (Gen 1) rather than completely new designs (like the Tesla Semi):
