Sun's Energy
Not all of the sun's energy comes down to the earths surface. The total energy from the sun that goes down to earth is 50%. 29% is carried to clouds and atmosphere by latent heat in water vapor. 20% of the suns energy is reflected by clouds. 64% of the suns energy is radiated to space from clouds and atmosphere. 3% is absorbed by clouds and 51% is absorbed by land and oceans. According to the physicist Hermann Von Helmholtz, the sun's energy is gravitational, and we only have about 20 million more years to use its energy.
