Timely reality check 

Using electronic devices to telecommute saves enough energy to power 1 million U.S. households for a year, according to a study released by the Consumer Electronics Association.

The study, commissioned by the association and conducted by TIAX of Cambridge, Mass., found that "just one day of telecommuting saves the equivalent of up to 12 hours of an average household's electricity use."

The country has about 3.9 million telecommuters, who collectively save about 840 million gallons of gas and 14 million tons of carbon dioxide emission a year. That's equal to taking 2 million vehicles off the road, the study said.
