kW vs kWh: What is the difference between Power and Energy?

On the other hand, "kWh" stands for "kiloWatt-hour", which is equal to 1000 Watt-hours, and "Watt-hours" is the conventional unit for measuring "Electrical Energy". 1 kiloWatt (kW) = 1000 Watts (W) 1 kiloWatt-hours (kWh) = 1000 Watt-hours (Wh) But this still doesn''t explain the difference, does it? Let me explain.
