Hello there, I'm an expert in energy efficiency and lighting technology. Let's dive into the cost of running a 100-watt light bulb for one hour.
Firstly, the cost of running a light bulb can be determined by a few key factors: the power consumption of the bulb, the cost of electricity in your area, and the duration for which the bulb is left on. The power consumption of a bulb is measured in watts, and in this case, we're considering a 100-watt bulb.
Now, let's break down the cost calculation:
1. Power Consumption: The bulb consumes 100 watts of power.
2. Electricity Cost: The cost of electricity varies widely depending on the region and the provider. For the sake of this calculation, let's use the average cost mentioned in the reference, which is 15 cents per kilowatt-hour (kWh).
3. Conversion to Kilowatt-Hours: Since 1 kilowatt equals 1000 watts, a 100-watt bulb uses 0.1 kilowatts of power.
4. Calculating Energy Used: If the bulb is on for one hour, it uses 0.1 kWh (100 watts * 1 hour).
5. Calculating Cost: Multiply the energy used by the cost per kWh. So, 0.1 kWh * $0.15/kWh = $0.015.
So, running a 100-watt light bulb for one hour would cost approximately 1.5 cents.
It's also worth noting that the type of bulb can significantly affect both the cost and the lifespan. Incandescent bulbs, as mentioned in the reference, are relatively inexpensive but have a shorter lifespan and are less energy-efficient compared to other types like LED or CFL bulbs. For instance, an incandescent bulb might cost around 50 cents and last about 750 hours, whereas an LED bulb, which is more expensive upfront but lasts much longer and uses less energy, could be a more cost-effective option in the long run.
Furthermore, energy efficiency is not just about the cost of running the bulb but also about the environmental impact. Using energy-efficient bulbs can help reduce carbon emissions, which is an important consideration for many consumers today.
In conclusion, while the immediate cost of running a 100-watt incandescent bulb for one hour is relatively low, considering the type of bulb, its efficiency, and the long-term costs can lead to significant savings and environmental benefits.

An incandescent light bulb costs about 50 cents and lasts about 750 hours. If you were to leave a 100-watt bulb burning for 24 hours each day, 365 days per year, it would use 876 kilowatt hours per year. ( 1000 watts equals one kilowatt -C --kilo-- means a thousand.) A kilowatt-hour of electricity costs about 15 cents.
