How much does it cost to make ice?

Could you please elaborate on the cost involved in the production of ice? I'm curious to know the various factors that contribute to the overall expense. Does it depend on the scale of production, or are there specific equipment requirements? Additionally, how does the cost vary based on the type of ice being made, such as flaked, cubed, or crushed? Is the cost primarily driven by energy consumption, raw materials, or labor? Finally, are there any ways to reduce the cost of ice production effectively? I'm eager to understand these aspects to gain a comprehensive picture of the economics behind ice making.
