What is the difference between Demand and Energy Consumption?

Imagine using 10 100-watt bulbs. The moment the 10 bulbs are turned on, they place a demand on the power system of 1,000 watts of electricity (10 bulbs x 100 watts each), or 1 kW. In this example, your meter would register 1 kW of demand. If these same bulbs are left on for 10 hours, they will consume 10,000 watt-hours of energy, or 10 kWh, and your meter would register 10 kWh of energy consumed.
