That doesn't follow at all. Why not?
There's plenty of sunlight in the areas with most of the people, and the areas with most of the farmland. We have storage solutions--they're still a little expensive, but they're certainly getting close.
If our current energy came from hydroelectric or geothermal could we replace it with solar? Your statement seems like a complete non sequitur.
- TeMPOraL 11y agoThis statement may be wrong but for different reasons - it boils down to just how much electricity vs. petroleum we need to use to make fertilizer. I don't know much about fertilizer manufacturing, but from a quick look at Wikipedia I think that for nitrogen ones we could conceivably replace natural gas with some other hydrogen source and run the whole Haber-Bosch stack off electricity.
