The amount of power used over time measured in kilowatt-hours is __________.

Explanation:
Energy is the total amount of electrical work used over time, and kilowatt-hours are the units for that energy. Power is the rate at which energy is used, measured in kilowatts. The kilowatt-hour combines these ideas: one kilowatt of power used for one hour equals one kilowatt-hour of energy. So when you talk about the amount of power used over time in kilowatt-hours, you're referring to energy. This is different from peak demand, which is the maximum instantaneous power drawn, and from power factor, which is a ratio describing how effectively electrical power is converted into useful work, not the total energy consumed.
