Coincidentally I just had dinner last night with a friend who is a career expert on electric vehicles and he said full size freight trucks will have electric motors by the year 2023 with a range of 250 miles fully loaded.
So if you ask this question 3 years from now you'll get completely different reply's as the advancements in the technology is very rapid.

No not at all
Those Trucks already exist, Tesla already makes an Electric truck not a pickup but a big rig and it can go for 4 hours and charge in 30 mins - absolutely a fantastic feat. However it has to be within a 4 hour drive of a charge point, now that charge point is huge and huge amounts of power.
The future of long distance travel is not electric! That’s just everyone jumping on the bandwagon as people always do, there is the longest line of so called Green solutions that end up as disasters out there - I can list them if you like.
Let’s have a try at that.
So
1) 1980s we are cutting down to many trees make everything out of plastic instead!
2) 1990s Catalytic converters on petrol engines - keeps the Green Party quiet while increasing fuel
consumption by 25% - well that kept the
oil companies happy 👍
3) unleaded fuel - nicely done away with by the need of the catalyst, oh 😯 but we could of done that anyway doh 🙄
4) oh dear there is plastic in the sea, omg I know let’s make the plastic biodegradable- that way none of the stupid people will be able to see it.
5) hey electric drive - yep you make a car that in 10 years has a range of 12 miles 👏 yet I still have the same car I had before you even made that one and it works just fine.
6) still too much plastic - well let’s make the plastic last longer - see plastic bag production down massively - I mean we are still using the same amount of plastic, just in less bags.
7) hey electric drive - yep we can make cars that won’t reach your
destination, OK well Tesla does but that’s limited, just how many Nuclear power stations do you need to power today’s road
network?
Here in the UK that number = 3 but that’s ok because in 20!years will have 1 new one and we will only be short of 2 more except that we will need more by then and we’ll the old ones will need decommissioning!
The only power is
oil until hydrogen arrives, hydrogen will only really be viable if we can produce more electricity than we need from clean sources, as it takes more energy to produce hydrogen than it gives back! and fundamentally the same is for Electric propulsion!
Electric drive - battle ships use this, they run on
diesel and convert it to electric!
Oh and the next disaster on it’s way is tighten the building emissions
regulations until only electric is viable! Sounds great because all that electric generation is someone else’s problem, so instead of burning gas to produce electricity and the latent heat used for
heating, no just electric
heating in the building, and then backup power on the grid with gas that produces all the heat except that the grid generation heat is dumped and not utilised!
I like the idea of silence though. Not a fan of listening to a
diesel powered sailboat, Bring on hydrogen?
