Why can't you electrify ambulances? They're specialized taxis, many short trips, spending a lot of time parked. Only time you need long range is for patient transfer between hospitals. Fire trucks only make short trips, and (ideally) have a tiny capacity ratio.
Ditto for construction vehicles, which rarely travel long distances, often want to be heavy for greater traction, and can have surprisingly low power output. (The Cat D5K2 weighs 20,000 pounds but only has a 105 HP engine: https://www.cat.com/en_US/products/new/equipment/dozers/smal... )

I can't speak for Norway, but in the United States it is very common for Ambulances to travel difficult roads and sometimes non-roads. They have heavy-duty engines for a reason.
Don't confuse power with torque. Big diesel engines run at super low RPM, so have low HP but high torque (since HP is just torque * RPM * a constant).
In business terms, we may be a long way from electric fire trucks, ambulances, and construction equipment.
In terms of the technology, I don't see anything stopping those from happening right now.

I believe the op is suggesting that there have been significant deferred costs associated with burning fossil fuels.
Also, I'm not sure what the OP is on about with this:
not taxing them for ruining our health and climate, for a start
Since electric cars aren't taxed, either, that's just playing with numbers.
