What is a kWh?

Most domestic appliances will quote their power consumption in kilowatts and many electric utility companies use the kilowatt hour as a billing unit. The kilowatt-hour (symbolized kWh) is a unit of energy equivalent to one kilowatt (1 kW) of power expended for one hour (1 h) of time. Here is an example: If your air conditioner consumes 3 kW per hour, and it operates 18 hours during a hot summer day, then your air conditioner used 54 kWh (3 kWh X 18 h) that day. If your rate is 17 cents per kWh, then your cost of operating your air conditioner was $9.18 (54 kWh X $0.17 per kWh) for the day.

Here are some examples what you can do with 1 kWh ( results may vary):


Use an electric shaver 1200 times
Dry your hair 15 times
4 evenings of watching TV
Listening to 15 CDââ?¬â?¢s in a row
Use a (small) refrigerator for 24 hours
Heat 20 microwave meals
Drill 250 holes
4 evenings of light with 60 W incandescent light
20 evenings of light with 11 W compact fluorescent light
