If 4,000J of energy is transferred and 2,500J is usefully stored, how much energy is wasted

If we do the simple equation of 4,000J subtracted by 2,500J  we can easily see that the energy that wasn't useful or wasted is 1,500J

4000J transfer and 2500J stored which means you have an energy produce power equals to 6500J. Therefore take 6500J and subtract it with 4000J transfer and there you left with 2500J. so the question is, how much energy is wasted? about 4000 of your energy is been transfer which means it moves out of the original source.
