Excerpt

It is difficult to imagine life today without electricity. Almost every minute of every day this silent force is serving us.

Jane puts on a skirt and a blouse that have been laundered in an electrically powered washer and dryer. She goes to the kitchen and takes a bottle of orange juice from an electric refrigerator, then pours a cup of coffee from a machine that has been programmed by electricity to have the coffee ready at eight o’clock. She toasts a bagel in an electric toaster, and while she is eating her breakfast watches the morning news on a television set that uses electricity to convert electromagnetic waves to visual images. When Jane has finished breakfast, she hastily sticks the dirty dishes into an electric dishwasher.

Jane then goes to the garage, where she punches a button to open the garage door automatically, starts her car with an electric battery, and sets off for work, getting weather and traffic reports on a radio operated by electricity. As she drives, electrically controlled flashing signs warn her of construction on the road ahead.

At work, Jane reaches her office floor in an elevator run by electricity . . .
