    Answer:

    the energy usage of the clock per year is 17.2 kWh

    Explanation:

    Given;

    power drawn by the clock, P = 2 W

    duration of the clock’s operation, t = 8,600 hours per year

    The energy usage of the clock per year is calculated as;

    E = Pt

    E = (\frac{2}{1000} )kW  \ \times \ 8,600 \ hr\\\\E = 17.2 \ kWh

    Therefore, the energy usage of the clock per year is 17.2 kWh
