Question

What Is A Kwh?

I don't understand the difference between kWH and kw.

Answer

A kilowatt hour (kWh) is a measure of how much energy you’re using.

It doesn’t mean the number of kilowatts you’re using per hour. It is simply a unit of measurement that equals the amount of energy you would use if you kept a 1,000 watt appliance running for an hour:

So if you switched on a 100 watt light bulb, it would take 10 hours to rack up 1 kWh of energy.

Or a 2,000 watt appliance would use 1 kWh in just half an hour.

While a 50 watt item could stay on for 20 hours before it used 1 kWh.
