1. The diagram below shows numerical estimates of annual energy fluxes on Earth, in units of 108 terawatt-hours (TWh), where 1 TW = 10 W. For example, the "15.1" solar input number at the top means that a total solar energy input of 15.1 x 108 TWh strikes the top of the Earth's atmosphere in one year, of which 0.024 x 108 TWh is used in photosynthesis.
