A better perspective is how much of the energy we already get that we're using. Some quick math tells me that to get 10x our current total energy usage in solar panels would only take 1% of the total surface of the earth, 3.4% of the land area and 56% of the Sahara. So just putting solar panels on deserts across the world and building a worldwide grid would be a much more feasible project than trying to capture directly from the sun. All those solar panels would cost ~13x our world yearly GDP so it's not completely unreasonable either. https://docs.google.com/spreadsheets/d/1B3Vtm-bk8NIntYc8mZRwcpikF-U2VkBDOLt8PaDjR1c/ https://docs.google.com/spreadsheets/d/1B3Vtm-bk8NIntYc8mZRw...
