Quick Math Summary
•The average power is equal to the product of the average current and the supply voltage.   
•    P = I * Vcc.
•Since power is the rate at which energy is consumed, the amount of energy consumed is equal to the product of Power and execution time.  E = P * T.
•Finally, the execution time is equal to the product of the number of clock cycles and the clock period.  T = N * t.
