A smart meter is an electronic device that records utility (e.g., electricity, gas, water) information, such as: | A smart meter is an electronic device that records utility (e.g., electricity, gas, water) information, such as: | ||

The smart meter can then communicate the information to the consumer and utility suppliers. Advanced metering infrastructure (AMI) differs from automatic meter reading (AMR) in that it enables two-way communication between the meter and the supplier. | The smart meter can then communicate the information to the consumer and utility suppliers.

*Demand pricing: Utilities can change the price of electricity over a day or week, for instance raising it when demand is high or supply is low. It is often difficult for consumers to shift major usage to off peak times, so many consumers wind up paying more with demand pricing. | *Demand pricing: Utilities can change the price of electricity over a day or week, for instance raising it when demand is high or supply is low.

*Cost and longevity: Smart meters are more expensive than traditional meters, they are also harder to recycle (having many more types of material in them). For example, a traditional electric meter can run for 70 years. It is hard to build smart meters that will not become obsolete much sooner than that. (For instance, encryption becomes vulnerable.) | *Cost and longevity: Smart meters are more expensive than traditional meters, they are also harder to recycle (having many more types of material in them).
