Question: is kwh kilowatts per hour?
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. ... 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.
