The northern US receives a lot of sunlight (similar to southern, mediterranean France) but has been less profitable in growing certain crops due to its shorter growing season and frost risk. But these are changing: https://www.epa.gov/climate-indicators/climate-change-indicators-length-growing-season https://www.epa.gov/climate-indicators/climate-change-indica... https://www.globalchange.gov/browse/indicators/frost-free-season https://www.globalchange.gov/browse/indicators/frost-free-se... logically one would expect agricultural output to increase in these areas as their solar potential is unlocked but there are other areas where the opposite will occur
