Look them up in the dictionary!

Power is the rate at which work is done... ie how fast energy is transferred from one type to another.

Yes, power is the work done in unit time.
P=dW/dt

Not to be coy, but I find it hard to believe that you've posted over 300 times on this site without knowing the difference between power and energy. Energy is simply a quantity changed within a system when external work is done on it, and power is the rate at which this work is done on it.
