The formula to calculate the energy cost of an aquarium is:
\[ AEC = P \cdot T \cdot E \]
Where:
Let's say the power used by the aquarium (P) is 0.5 kW, the average run time per day (T) is 10 hours, and the cost of electricity (E) is $0.12 per kWh. The aquarium energy cost would be calculated as follows:
\[ AEC = 0.5 \cdot 10 \cdot 0.12 = 0.6 \text{ $/day} \]
So, the aquarium energy cost is $0.60 per day.
The amount of energy that an aquarium uses is mostly determined by the water pumps and lights used by the aquarium. These components can significantly affect the overall energy consumption and cost.
