Land Area Required for PV Energy

2030 use would require 500k sq km.

Area of earth is 500M sq km.

Area required is only 0.1% of available land area of earth.

Cities already cover 3% area. Covering 1/30th of the area of cities with PV generation could provide all the energy. Need to multiply that by 4, since the sun shines 6 hours per day on average.
