Good batteries-could it happen?
But only because I don't expect it to provide 100% of my power in all climates (i.e. when it rains for days in a row) and all power consumption needs (i.e. when we do spring cleaning and run the dryer a lot to wash bedclothes in guest bedrooms that haven't been used in months, while driving a lot during the day and having to charge the EV). Thus, I have the understanding that even I need a dependable grid for those hard to reach times that it'd be infeasible to set up an off-grid system for us.
The grid doesn't have a backup grid for the times solar doesn't do. The grid has to be dependable all the time, rain or shine. That's why I don't like making the grid depend on solar and wind.
Of course. For example, when they invent room temperature superconductors (which could happen someday) that would go a long way.
Humans are very ingenious, especially when there is money to be made!
