Question: what is the difference between power (kw) and energy (kwh)?
Answer: A kilowatt-hour (kWh) and a kilowatt (kW) may sound like the same thing, but they're not quite tomato-tomahto. While both are interrelated units of measurement, the important difference between kWh and kW is that a kWh reflects the total amount of electricity used, whereas a kW reflects the rate of electricity usage.
