What is the average cost of running a mini-fridge?
The average cost of running a mini-fridge can vary depending on several factors, including the size of the fridge, its energy efficiency, and the cost of electricity in your area. However, based on the US Energy Information Administration’s estimates, a mini-fridge with a capacity of around 3.2 cubic feet can cost between $20 and $50 per year to run.
To give you a better idea, let’s consider an example. Suppose you have a mini-fridge with an energy consumption of 100 kWh per month, and your electricity rate is 12 cents per kWh. In this case, your monthly electricity bill for the mini-fridge would be around $12. Over the course of a year, this would translate to an annual cost of around $144.
How does the size of the mini-fridge affect its energy consumption?
The size of the mini-fridge is a significant factor in determining its energy consumption. Generally, the larger the mini-fridge, the more energy it will consume. This is because larger fridges require more power to cool the interior and maintain the desired temperature. For example, a mini-fridge with a capacity of 4.5 cubic feet may consume around 150 kWh of electricity per month, while a smaller one with a capacity of 2.4 cubic feet may consume around 80 kWh per month.
However, it’s worth noting that some mini-fridges are designed to be more energy-efficient than others, regardless of their size. Look for mini-fridges with the ENERGY STAR label, which indicates that they meet energy efficiency standards set by the US Environmental Protection Agency.
