Nancy Downs
Nancy used this power to turn on Sarah's TV set and show her the "plane crash" that her father and Jenny "died" in. She then used it to shut off all the power to Sarah's house.

She may have used this power to blow up a microwave oven immediately before causing the death of Ray Sanders.
