Your snarky analogy doesn't really make sense because the power infrastructure in Australia runs all night long with no need for batteries. Or did you think that Australia's coal and NG plants shut down in the evening? But sure, you could put that Spain-sized solar farm in the Sahara. Then it's just a simple matter of pacifying the Islamic militants and whoever else while building a global-scale power distribution network, and convincing opposing powers such as NATO, Russia, and China, to give up their domestic power infrastructure and put national security at risk by relying on one giant point of failure all while coordinating construction projects (with their increased electrical demands) on a global scale. I won't even get into the size of the battery farm required to store a continent's energy needs. The United States used 1.068E20 joules of electricity in 2018: Divide by the number of seconds in a year and there's your wattage, I'll leave it to you to figure out the rest. edit: and we're still ignoring transmission losses at transcontinental scale
