Evaporative Coolers. In low-humidity areas, evaporating water into the air provides a natural and energy-efficient means of cooling. Evaporative coolers, also called swamp coolers, rely on this principle. By passing outdoor air over water-saturated pads, the water in the pads evaporate, reducing the air temperature by 15°- to 40°F-before it

How Energy Storage Works | Union of Concerned Scientists

Simply put, energy storage is the ability to capture energy at one time for use at a later time.
