 Humanity uses around 1.5e13 W, and the Earth receives around 1.366e3 W per m² from the Sun (varies with year and month). Earth has a land area of around 1.5e8 km². Assuming 10% efficiency for photovoltaics, that means we need to cover around 1.1e5 km² with solar cells. That is around the land area of Cuba. -- Markus Sablatnig Humanity uses around 1.5e13 W, and the Earth receives around 1.366e3 W per m² from the Sun (varies with year and month).
