The solar power arrays around the world, from giant farms to personal solar panels, have the capacity to generate as much power as sixteen coal burning plants or one nuclear reactor, but with clean energy. As more and more solar arrays are installed in nations across the continents, the world’s dependence on oil and other fossil fuels shrinks, helping to pave the way for continued renewable energy in the future.
Solar areas defined by the dark disks could provide more than the world's total primary energy demand (assuming a conversion efficiency of 8%). That is, all energy currently consumed, including heat, electricity, fossil fuels, etc., would be produced in the form of electricity by solar cells. The colors in the map show the local solar irradiance averaged over three years from 1991 to 1993 (24 hours a day) taking into account the cloud coverage available from weather satellites.
