I was wrong :)
BUT if it’s become so cheap, why can’t it replace fossil fuel in some areas and why would fossil fuel have to run 24/7 if alternate energy could keep a whole town running?
Not sure why.
Only know that it takes hours/days to get boilers up to steam pressure to take over as the wind dies, or clouds cover the sun.
I guess it works for your home, as you’re always plugged in for backup, or an expensive battery pack can provide for your own needs. But the battery backup doesn’t scale up.
