    Step-by-step explanation:

    P = IV

    2000 W = I (120 V)

    I = 16.7 A

    P = E/t

    P = (2000 W * 8 hr) / (1 day)

    P = 16,000 W·hr/day

    P = 16000 W·hr/day * (365 day / yr)

    P = 5,840,000 W·hr/yr

    P = 5,840,000 W·hr/yr * (1 kW / 1000 W)

    P = 5840 kW·hr/yr

    C = 5840 kW·hr/yr * (0.25 $/kW/hr)

    C = $1460/yr
