Calculating the Energy Consumption

To determine the annual cost of operating the 3.00-W electric clock, we must first calculate its annual energy consumption. Power, measured in watts (W), represents the rate at which energy is used. To find the energy consumed, we need to consider the time the device operates. Since the clock runs continuously, it operates for 24 hours a day. The following steps outline the calculation process:

1. Convert Watts to Kilowatts: The standard unit for electricity billing is kilowatt-hours (kW·h). Therefore, we need to convert the clock's power consumption from watts to kilowatts. To do this, we divide the power in watts by 1000:

   3. 00 W / 1000 = 0.003 kW

   This conversion is crucial because electricity bills are typically calculated based on kilowatt-hours, which represent the amount of energy consumed over time. Converting watts to kilowatts allows us to directly correlate the clock's power usage with the billing units used by utility companies. Furthermore, this conversion facilitates comparisons with other appliances, as their energy consumption is often expressed in kilowatts. By performing this initial conversion, we set the stage for a more accurate and meaningful calculation of the clock's annual energy consumption.

2. Calculate Daily Energy Consumption: Next, we calculate the energy consumed by the clock in a single day. This is done by multiplying the power in kilowatts by the number of hours the clock operates per day:

   3. 003 kW * 24 hours/day = 0.072 kW·h/day

   This step is essential because it bridges the gap between instantaneous power consumption and daily energy usage. By determining the kilowatt-hours consumed per day, we gain a clearer understanding of the clock's energy footprint over a 24-hour period. This daily consumption figure serves as the foundation for calculating the annual energy consumption, providing a manageable unit for further analysis. Moreover, understanding the daily energy usage can help in comparing the clock's energy consumption with other daily activities and appliances, offering a more contextual perspective on its overall impact.

3. Calculate Annual Energy Consumption: To find the total energy consumed in a year, we multiply the daily energy consumption by the number of days in a year (365 days):

   4. 072 kW·h/day * 365 days/year = 26.28 kW·h/year

   This calculation provides the total energy consumed by the electric clock over the course of a year. This annual energy consumption figure is a critical metric for assessing the long-term cost of operating the clock. It represents the total amount of electricity the clock will draw from the grid in a year, directly impacting the electricity bill. This value is also essential for comparing the energy efficiency of different clock models or considering alternative timekeeping methods. By determining the annual energy consumption, we can move on to calculating the total cost of operating the clock, providing a comprehensive understanding of its financial implications.

Determining the Annual Cost

Having calculated the annual energy consumption, we can now determine the annual cost of operating the 3.00-W electric clock. This is done by multiplying the annual energy consumption by the cost of electricity per kilowatt-hour. The cost of electricity is given as $0.0900 per kW·h. The calculation is as follows:

Annual Cost = Annual Energy Consumption * Cost per kW·h

Annual Cost = 26.28 kW·h/year * $0.0900/kW·h

Annual Cost = $2.3652 per year

Therefore, the cost of operating the 3.00-W electric clock for a year is approximately $2.37. This seemingly small amount can be quite enlightening, as it demonstrates the cumulative cost of running even a low-power device continuously over an extended period. While $2.37 may not seem like a significant expense, it is essential to consider this cost in the context of overall household energy consumption. The combined energy usage of various small appliances, like clocks, can add up to a substantial amount over time. By understanding the cost of operating individual devices, consumers can make more informed decisions about their energy usage and identify opportunities for savings.

Furthermore, this calculation highlights the importance of considering the long-term costs of appliances. While the initial purchase price of an appliance is a significant factor, the operational costs can often outweigh the initial investment over the lifespan of the device. This is particularly true for appliances that operate continuously, such as electric clocks. By factoring in the annual operating cost, consumers can make more financially sound decisions when purchasing new appliances. This long-term perspective is crucial for effective budgeting and financial planning.

In addition to the financial aspect, the annual cost calculation also underscores the environmental impact of energy consumption. Every kilowatt-hour of electricity consumed contributes to the overall demand on the power grid, which often relies on fossil fuels for generation. By reducing energy consumption, we can decrease our carbon footprint and contribute to a more sustainable future. Understanding the cost of operating appliances like electric clocks can motivate us to adopt energy-saving practices and choose more efficient alternatives.
