A cold-water-only water cooler uses 0.3 kWh per day, which equals about $25.00 a year. A hot and cold water cooler uses 2.8 kWh per day, or an estimated $227.00 a year. Adding a timer to these water coolers drops the usage per day and cost per year slightly.

Water coolers given the Energy Star qualification use up to fifty percent less energy than other water coolers. In order for a cooler to be Energy Star efficient, it must use less than 0.16 kWh/day if cold water only or less than 1.2 kWh/day if it is both hot and cold water.
