A 40%-efficient electric power plant produces 900 of electric power and discharges waste heat into 20C

ocean water. Suppose the waste heat could be used to heat homes during

the winter instead of being discharged into the ocean. A typical

American house requires an average 20 kW for heating.

How many homes could be heated with the waste heat of this one power plant?
