Battery prices plummetting, and V2G from EVs, is a path for near tropical regions to get to 90% solar energy. Robotics based manufacturing shifting to those regions is also a likely shift. Northern lattitude quality of life from global warming, is still a nice source of population attractiveness. Hydrogen made from solar is the path to 100% renewables and solar everywhere. Canada is a decent place for solar because of extremely long summer days. Canada can both make H2 in summer, and use H2 in winter. Even near tropical locations would have large spring and fall surpluses to cover near full summer demand from solar. They also need to make H2 from those surpluses.
