WebNearly one third of this is reflected back into space by clouds, water, ice etc. The rest of the solar radiation is absorbed and provides the energy for almost all the natural processes on Earth, as shown in Figure 42.1. The energy is shown in units of GigaWatt (GW) – about equal to the output of a large electricity generating station. WebThat means that about a third of the solar energy that gets to Earth is reflected back to the atmosphere and space and about two thirds (51% by land and ocean, and 16% by atmosphere) is absorbed. The Moon’s albedo is 0.12, much lower than that of Earth.
