Kilowatt-hours are a measurement of electric power, commonly used to quantify home electricity consumption, solar energy production, or EV battery capacity in the United States. Breaking down kWh measurements piece-by-piece, a kilowatt is a unit of energy equal to 1,000 watts and an hour is… well, an hour, or sixty minutes.
Wh = W x hours of usage. For example, if you have a 65W lightbulb that is turned on for 3 hours a day, you could use this equation: 65W x 3 hours = 195Wh. But these calculations provide energy usage as watt-hours. Since utilities measure our electricity usage in kilowatt-hours, we need to divide the watt-hours by 1,000. In our previous ...
