    The solution for the problem is:

    1 Watt = 1 Joule per second

    1 Watt*second = 1 Joule

    a Kilowatt is 1,000 Watts

    an hour is 60 seconds times 60 minutes or 3,600 seconds

    a Kilowatt * hour is 1,000 Watts in 3,600 seconds

    15 W*h = 15,000 Watt*hour = 15,000 Watt * 3,600 seconds = 54,000,000 Watt*second

    54,000,000 Watt*second = ? Joules

    54,000,000 Joules / second = 54,000,000 Watts
