> Solar, wind, geothermal, and hydro are more than enough to power the world Cool story. My city of 7M people has ~50 days of sunny days per yer, is located on a plane (as the most part of large cities), doesn't have active underground volcano nearby (as 99% of Earth's cities) and requires indoor heating at least 7 months/year. The city consumes an equivalent of two nuclear power plants output in electricity alone (half of that is from an actual nuclear plant). Heating probably consumes even more energy, but it's direct heat from CHPs so I can't google direct MW numbers straight away. I'd like to see calculations on powering that from solar, wind, geothermal, and hydro.
