WebE: Radiate energy. σ: Stefans’s-Boltzmann constant. T: Absolute temperature in Kelvin. e: Emissivity of the material. A: Surface area of the body. The dimension of the radiate energy E is energy flux. Joules per second per square metre, or watts per square metre, is the SI unit of the radiated energy. Stefan’s Constant WebThe total radiant flux (power output) of the Sun is about [math]3.8\times10^ {26} [/math] joules per second. Earth’s energy usage in 2013 was about [math]3.9\times10^ {20} [/math] joules. So the Sun’s energy output in a second is almost exactly 1,000,000 times greater than all of Earth’s energy consumption in the year 2013.
