The entire scientific Astronomical and Cosmological community assumes that it's the Doppler effect, since that's the only existing scientific explanation for the shifts in wavelengths away from what they're supposed to be.  The whole theoretical structure of the "Big Bang" and the expanding universe is built on that understanding.

If anybody ever comes along and discovers another way for electromagnetic waves to get longer or shorter on their way to us through space, then the whole big bang and expanding universe may be out the window.

What's the formula to find out power
Julli [10]

In general, 

                 Power = (energy moved) / (time to move the energy) .

If it's mechanical power, then     

                 Power = (work done) / (time to do the work) .

If it's electrical power, then it can be any one of these:

                 Power  =  (volts)  x  (amperes)

                 Power  =  (volts)²  /  (resistance, ohms)

                 Power  =  (amperes)²  x  (resistance, ohms) .

Whatever kind of energy you're dealing with, power always
turns out to be

                  (amount of energy produced, used, or moved)
divided by
                  (time taken to produce, use, or move the energy) .
