The rising mercury in Miami has recently forced me to once again employ the services of our ceiling fans, which got me to thinking about the attached lighting. Each of my kids has a Hampton Bay ceiling fan in their rooms, which provides lighting by way of four incandescent bulbs. Each bulb burns 40 watts. That would be a total output of 160 watts which, interestingly, is less wattage than some heat lamps on the market! No wonder I'm always burning up in this house :-(
As always, let's choose to err on the side of caution and say that, conservatively, the ceiling fan lights are on for a total of two hours every day (1 hour in the morning, and 1 hour at night.) If that's the case, and we calculate for both kids' rooms, then:
160 watts ÷ 1,000 = 0.16 kWh
0.16 kWh x 2 hours = 0.32 kWh/day
0.32 kWh/day x 2 rooms = 0.64 kWh/day total
0.64 kWh/day x 365 days = 233 kWh/year
We are at once both lighting and heating our kids' rooms to the tune of 233.6 kWh every year. Soaring south Florida temperatures may force my hand in terms of cooling, but I'm not gonna be a sap when it comes to lighting!
