Global energy use of all types (including fuels) is about 18 terawatts today, so this is a scenario where all the fuel a growing world could want are made in the Sahara, and Africa's drinking water is probably desalinated, to boot. Scott K. Johnson, Ars Technica, "Carpeting Sahara with wind and solar farms could make it rain," 8 Sep. 2018 The researchers simulated the effects of around 79 terawatts of solar panels and 3 terawatts of wind turbines. Avery Thompson, Popular Mechanics, "How Solar Panels in the Sahara Could Make It Rain More," 7 Sep. 2018 To put that number in perspective, the total amount of solar power added by all the world’s nations in 2017 was slightly less than a tenth of a terawatt, so this research isn’t immediately relevant for today’s renewable installations.

David Roberts, Vox, "The simple argument for keeping nuclear power plants open," 5 Apr. 2018 Humans used over 20,000 terawatt-hours of electricity in 2016 alone, and building enough solar plants and wind farms to produce that much energy is a Herculean task. Avery Thompson, Popular Mechanics, "Planned Solar Farm Would Be Hundreds of Times Bigger Than World's Current Largest," 4 Apr. 2018 The report notes as of Tuesday, electricity consumption from Bitcoin rose to a record high of 47.4 terawatt-hours, citing the Digiconomist bitcoin analysis blog. Dino Grandoni, Washington Post, "The Energy 202: Democratic senators demand Pruitt recuse himself from rewriting Clean Power Plan," 7 Feb. 2018 Miners of bitcoin and other cryptocurrencies could require up to 140 terawatt-hours of electricity in 2018, about 0.6 percent of the global total.
