What does kwh mean?

kWh stands for kilowatt-hour, which is a unit of energy. It measures the amount of electricity used or produced over time.

• 1 kWh is equal to 1,000 watts (or 1 kilowatt) used for one hour.
• For example:
  A 100-watt lightbulb running for 10 hours consumes **1 kWh (100W × 10h = 1,000Wh = 1 kWh).
  A 1,500-watt heater running for 2 hours uses 3 kWh (1.5 kW × 2h = 3 kWh).

kWh is commonly used in electricity bills to measure how much energy a household or business consumes.
