Do evaporative coolers use a lot of electricity?

Evaporative coolers, also known as swamp coolers, are an energy-efficient alternative to traditional air conditioning systems. They use significantly less electricity than traditional air conditioners, as they rely on the natural process of evaporation to cool the air. Evaporative coolers use a fan to draw in hot, dry air from outside and pass it over a wet pad. As the air passes over the pad, it is cooled by the evaporation of the water, and then the cooled air is circulated throughout the house. This process uses very little electricity, making it an economical and energy-efficient cooling option.
