A kilowatt (kW) is a unit of power that measures how much energy is used or produced in one hour. It is commonly used to describe the output of engines and the power consumption of electrical devices. For example, a typical light bulb might use about 60 watts, which is 0.06 kilowatts. Understanding kilowatts helps us gauge how much electricity we consume in our homes and businesses. In the context of electricity, kilowatt-hours (kWh) is another important term. It represents the amount of energy consumed over time, specifically one kilowatt used for one hour. This measurement is what you see on your electricity bill, helping you understand your energy usage and costs.
