One interim technology, which could serve as a bridge to greater awareness of
smart appliances, is smart plugs, according to the report. These devices
act as sensors for conventional appliances and electronic devices, enabling
consumers to track electricity usage by the outlet. While the number of
smart appliances remains low, and prices of available models remain high, smart
plugs may be able to provide consumers with a way to save money on energy bills
while familiarizing themselves with smart household technology and its benefits.
