Whats a “kWh,” and why is it important?
A. “kWh” or kilowatt-hour, is 1,000 watt-hours, the standard measurement for electricity consumption. For example, a single 100-watt bulb will use up 1 kWh after 10 hours. At a kWh rate of $0.08, the cost to light that 100-watt bulb for 10 hours would be $0.08. To better understand your electricity usage, check out Energy Tips.
