At times of peak demand for electricity, do you want your refrigerator to run at the discretion of the power company?

The U.S. Environmental Protection Agency has revised its Energy Star energy-efficiency requirements for residential refrigerators, and it is encouraging the inclusion of “connected” features that respond to utility signals to curb their energy consumption.

The EPA announced the new requirements on June 27. Included is the optional “smart-grid” connection for customers to electronically connect their refrigerator or freezer with a utility provider.
