And how do you plan on electrifying such massive ships?
Electrifying cars is easy and electrified railways have existed for more than a century now, but good luck electrifying airplanes or cargo ships, they’re just too big and don’t run on tracks
I think with ships a good starting point would be making them burn cleaner fuel. The heavy oil they’re currently burning on ocean trips isn’t exactly the cleanest fuel around, having ships burn the gasoline we save from electric cars would already do a lot.
Just thinking out loud here, but if the main problem with building 2.5 billion EVs is making the batteries, why would that change anything if those 90,000 cargo ships each need 56,000 EV’s worth of batteries? I’m sure there’s some efficiency to be gained by making larger batteries, but it still doesn’t quite add up.
Of course this also assuming a cargo ship is as efficient as a car in terms of replacing the ICE with an electric motor. I’ve heard the fuel these cargo ships use is some of the worst quality fuel that we have and it doesn’t burn well, but it’s very cheap in the insane quantities they need.
It’s way easier to electrify cars than cargo ships, because you can refuel/recharge cars every few kilometres. This is simply not possible with ships, other more expensive technologies like hydrogen or artificial fuels are needed. Electrifying cars also helps to reduce other emissions like nitrogen oxides and particulate matter, which is good for your health.
Giant flexible solar sails on shipping freighters powering the engines and catching wind could be an interesting and old school way of moving products. I think possibly direct airship shipping would be more interesting. Tens of thousands of slow moving solar powered airships moving freight without having to deal with multiple transportation solutions.
Pickup at factory, move across ocean on airship, deliver to customer. Much better than pickup at warehouse deliver to terminal, move to carrier, carrier moves it to terminal, load on ship, cross world, unload off ship, loads container onto train, train take container to yard, stores at yard, loaded onto truck, deliver to terminal.

Now this is a more reasonable take, first try finding a more sustainable fuel to use then think of a way to electrify it (if at all possible)
Start with banning nonessentials such as cruise ships and get rid of private jets while we’re at it, to start at least.

But I thought climate change was all my fault, and that if I just use less water in my garden everything will be fixed.
Are you saying that the news lied to me?!?

That’s actually not true, right? https://www.iea.org/data-and-statistics/charts/global-co2-emissions-from-transport-by-sub-sector-in-the-net-zero-scenario-2000-2030
In 2019 there are 6.08 Gt from road vehicles compared to the 0.87 Gt from shipping. That’s just overwhelming.
