Solar Energy Potential and Utilization | EARTH 104:
The surface of the Earth receives solar energy at an average of 343 W/m 2. If we multiply this times the surface area of the Earth, about 5x10 14 m 2, we get 1715x10 14 W. But, 30% of this is reflected, and only 30% of the Earth is
Solar Spectra
The O 3, O 2 and H 2 O in the aerosphere selectively absorbed a small fraction of the primordial sunlight spectrum, while most part of the sunlight passed through the atmosphere and arrived
The Sun''s Energy: An Essential Part of the Earth System
It takes solar energy an average of 8 ⅓ minutes to reach Earth from the Sun. This energy travels about 150 million kilometers (93 million miles) through space to reach the top of Earth''s atmosphere. Waves of solar energy radiate, or spread
