Ditto what both of you wrote.

Energy Density is the issue, and regardless of all the PR around EVs, they simply do not have the energy density to compete with fossil fuel.

Unless, or until, some fundamental break through in battery technology comes along, they will remain a niche and very expensive product.

The current (no pun intended) technologies are jokes for serious transport energy requirements.

Conversion costs from diesel or gasoline to CNG can also be killers. I read or heard somewhere that to convert from one or the other to CNG requires an EPA-certified shop, and for something like a bus it runs around $100K with all the safety and QA required. Not that those are bad things for public transport, but my town looked at it for their public transit system and decided on a go-slow approach, where they'd do the conversions a few at a time and see if it panned out. The key issue was the cost per mile driven using diesel vs. CNG. At the time the equivalent cost for diesel vs. CNG was something like $3 diesel and 80 cents for CNG for the same number of vehicle-miles (I can't recall what that was). But given the conversion cost and vehicle lifetime it came out just a little on the positive side, (as long as CNG is cheap compared to diesel).

I guess it's worth looking at for a vehicle that is on the street a lot, every day, carrying a fair number of people. But, being retired, I'm driving less than 40 miles a week unless its vacation or a consulting job somewhere. So it doesn't make sense for a homebody like me to try either CNG or EVs. I'm gonna be dead before I see a net positive ROI.
