The Sun is generally considered to produce a constant amount of power (although there are small variances in the output energy depending on sunspot cycles) with a surface intensity of 6.33×107Wm2.
Not all of the solar energy that reaches the Earth's atmosphere is absorbed by the Earth. This is due to something known as.
Energy that is absorbed by the Earth is not the same as the energy incident on the Earth's surface. On a perfectly clear or cloudless day, when the Sun is directly overhead (or at the "zenith"), solar irradiation i.
Earth's energy budget (or Earth's energy balance) is the balance between thethatreceives from theand the energy the Earth loses back into . Smaller energy sources, such as Earth's internal heat, are taken into consideration, but make a tiny contribution compared to solar energy. The energy budget also takes into account how energy moves through the Solar energy is received by the Earth through photosynthesis, which converts solar energy into chemically stored energy1. This produces food, wood, and biomass from which fossil fuels are derived. The energy received by the Earth is known as incoming solar radiation, which is termed as insolation2. As the Earth is a geoid resembling a sphere, the sun’s rays fall obliquely at the top of the atmosphere and the Earth intercepts a very small portion of the sun’s energy2.
