If we are talking about the last kilometer (‘ last mile ‘), the vans and trucks for local transport:
Goods reach their destination with less CO2 emissions (depending on the energy grid, but each year the CO2 footprint becomes less)
They also do not cause local pollution and this will make a real difference.In the United Kingdom on a main axis route to a city. They have checked the air quality and found it to be inadequate, mainly as a result of lorries and vans delivering goods. The traffic is slow, running idle and engines need to make more rpm than if the traffic would flow well.
The costs of deliveries will fall in the longer term.This seems counterintuitive, but that’s really not. The last kilometer is a very large part of the cost. Electric vehicles cost much less in use and maintenance. Probably half or a third. Yes, they cost more to buy, but unless a city-like London-introduces a low emission zone to force change substantially, supply companies will only replace vehicles if they need it, they will not be made to spend money That they weren’t going to spend anyway. Then they run their new electric car at considerably lower costs. Cost prices go down. Now imagine that the vehicles are even without a driver, then you have lowered the costs by not 50%-60% but with 80-90%.
Will there be delays?Maybe initially, but this is a sector that manages to get the optimization very well. They are going to invent how you can get goods just as quickly where they should be as with the current means of transport, but even if it is done something else, it will not be impossible.
The electrification of the last kilometer is easier than other parts of the chain.
Air freight and sea freight will not change quickly.Your answer specified all vehicles and since large electric planes are at this time unfeasible, my answer is that all goods currently flown must be transported in a different way. So no more fruit out of season for you.
Long-haul transport by lorry: it might be possible to electrify some or even everything.Of course, truck drivers oppose this, but as soon as electric trucks become available and the vastly lower operational costs are realised, they climb over each other to get one. As for driverless, let’s assume you are an owner-operator of a truck. You can buy a new electric autonomous (self-propelled) truck, which is certainly pricey, but trucks are expensive now, this new variant costs 30-40% more in purchase. Now you don’t have to sit there all day. It drives itself. It is your possession, you are paid for the loads you carry, but it drives 24/7 and only stops to load, and even if this lasts for an hour or two, it’s not as if the truck should be stationary for 10-14 hours a day as of now. Of course, a lot has to happen to make this happen, such as high power charging points in places where trucks drive, and load/unload and charging systems/people where the driver had previously been involved. But imagine that a transport company does not cause local pollution, the fuel (electricity) but 1/4 is of the diesel price, 24/7 drives (minus what charging time, part of which will overlap with charging) and with a safety 10 to 100 times better than Human drivers. Doesn’t sound too bad, right?
