Electric boats sound like a good idea to me couldn't wind, solar and tidal power all be combined. Making me wonder why supertankers, cargoships etc can't be doing some of that.
The issue is energy density. There's a reason why boat tanks are ~6 times larger than a cars gas tank. That's why they're so expensive (plus batteries are much heavier).
If electric were economical the world's shipping companies would have switched over. The logistics industry doesn't care about whether or not climate change is real, they just want to move stuff as cheaply as possible
