Meet Solar’s Imaginary Friend, Reactive Power

Utilities deliver both active (or real) power and reactive (or imaginary) power along their distribution lines. Real power does the actual work when you flip on a light switch. Certain energy loads, such as motors and refrigerators, include energy storage elements that periodically need to reverse the direction of energy flow. This electric power from stored electromagnetic energy, which returns to the source in each cycle, is known as reactive power.
