**Energy Consumption Comparison: Household Items**

To better understand energy usage in a household, let's compare two commonly used items: a toaster oven and a compact fluorescent light (CFL) bulb. This exercise demonstrates how to calculate energy consumption in kilowatt-hours (kWh).

**1. Toaster Oven:**

Calculate the energy used by a 1.00 kW toaster oven, which is used for 5.20 minutes.

- **Power Rating:** 1.00 kW
- **Usage Time:** 5.20 minutes

**Formula:**
\[ W_{\text{toaster}} = \text{kWh} \]

**2. CFL Bulb:**

Calculate the energy consumption of an 11.0 W CFL bulb when it is left on for 9.00 hours.

- **Power Rating:** 11.0 W (converted to kW: 0.011 kW)
- **Usage Time:** 9.00 hours

**Formula:**
\[ W_{\text{light}} = \text{kWh} \]

By calculating these energy consumptions, you can better understand the efficiency and cost associated with each appliance.

It seems hard to justify spending $4.00 for an LED lightbulb when an ordinary incandescent bulb costs $0.50. To see if it makes sense, compare a 60 W incandescent bulb that lasts 1000 hours to a 10 W LED bulb that lasts 20,000 hours. (These are typical values.) Both bulbs produce the same amount of visible light and are interchangeable.
