How many terawatts of solar radiation does the Earth receive? What percentage of solar radiation is reflected back by the atmosphere? The areas that people live in typically receive what range of kWh/m2 per day? How many terrawatts of radiation does the earth receive? How much of the solar radiation is reflected back into space? What are the insolation levels of most populated areas? Where is the solar radiation not reflected back to space absorbed?
The Earth receives 174,000 terawatts (TW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet. Most people around the world live in areas with insolation levels of 150 to 300 watts per square meter or 3.5 to 7.0 kWh/m2 per day.
