So some back of the napkin estimates. Assuming we just talk in terms of solar panels to make the math simple...
To power the world it would take 51 billion solar panels which have an average lifespan of 25 years (sources cited at the end).
A solar panel requires mostly aluminum and copper to construct it with 12% being copper, 87% aluminum, and 1% other stuff like silver and lead.
Solar panels require about 21 tons of aluminum and 2 tons of copper to produce 1 MW of power producing potential from solar panels. Thats 12.6 lbs of aluminum and 1.3 lbs of copper per panel.
So total to support a world running on solar panels would take 321 million tons of aluminum and 33 million tons of copper every 25 years.Or 64 million tons of aluminum and 6.4 million tons of copper every year.
Figuring out how much of that would effect shipping is the tricky part, and will take a little bit of hand waving. But in 2022 there were 69 million tons of new aluminum consumed per year. Similarly there was 25 million tons of copper consumed each year. That means the total need for aluminum would almost double and the global need for copper would increase by about 20%. Thats a total increased ore shipment across the two ores of 75% increase.
Your average freighter can carry 165K tons of freight. So to carry the new resources it would take 440 additional shipping freight cargo ships making a trip each year.
By estimates there are "hundreds of thousands of shipping vessel crossings every year" So assuming going away from fossil fuels cut shipping vessle crossings in half we are talking about saving somewhere on the order of 50K+ crossings every year but adding back only about 440 crossings each year.
