> What will be kept as backup for days with little production btw? Australia is different to Germany. We get high solar output every day, even in winter, and while we do get some wind droughts, they are less long and widespread than in Europe. We don't need to 'back up' anything close to 100% of our renewable capacity, and we don't need 'back up' for very long durations.
