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.
How many terawatts of solar radiation does the Earth receive?

For English Dominican mystics, the mystical experience was not expressed just in one moment of the full knowledge of God, but in the journey of, or process of, faith.
