The real problem is that some of the most important fertilizers are synthesized basically from methane. And about 25% of natural gas is exported via the Hormuz strait. This is something solar energy currently cannot tackle.
You can run the numbers the cost isn't that bad to do it that way.
I think South Africa gets most of its diesel from the Fischer–Tropsch process. You could use electrolytic hydrogen as an input for that. About 40% of the energy in gasoline is from hydrogen burning.
It's not great but it would allow you to run current vehicles off about 40% solar energy.
It’s less important to get it fully perfectly done this season and more important to actually do it at a short-medium timescale. Why are we still so dependent on the Middle East and Russia?
Solar and wind needs another source for base power since it is not constant 24/7 365 days and that other source is often natural gas. Nuclear on the other hand works 24/7 all year.
Solar and wind doesn't get a single ounce of grain or rice in to the market. No, actually, let me correct that. Solar and wind gets rice and grain to the markets, but only enough for roughly one billion people globally.
