How much energy is radiated from the earth to space?
AE = Area of Earth
εE = Emissivity of Earth
TE = Temperature of Earth
Tsp = Temperature of Space
Tsp = 2.7 K (off of NASA web page)
P = AE εE σ (TE4 - Tsp4)
The Attempt at a Solution
Isn't the relevant equation the answer to the question? The average temperature of the earth is "all over the place" depending on which web site, college, governmental agency or science club you look at. If I picked an temperature of the earth, then I could calc. the power correct?
