Energy usage certainly depends on the television owned. A chart of energy efficiency at CNET
shows HDTV power consumption costing yearly anywhere from $10.59 for the calibrated settings on a 32” Sharp LCD to $108.07 for a 58” Panasonic plasma television. But this did not tell us if the cost would go up or down by turning it off frequently.
Unable to find the exact information for our patron online, we decided to contact a television repair business. Our staff phoned Portage Electronics in Ravenna. They informed us that each time the power button is pushed it creates a 5 volt spike of electricity, which in time will burn out the microprocessor. They recommended that turning it on and off would cause more damage to the television than would save her money in electricity.
We did find that conversely avoiding the viewing of commercials can save you money. “According to Boston College sociologist Juliet Schor, ‘Television viewing results in an upscaling of desire. And that in turn leads people to buy.’ Her study found that every additional hour of TV viewing per week boosts spending by roughly $200 a year.”
It seems that leaving your television on during commercials will protect it, saving you money in repairs. Leaving the room or muting the commercials when they come on will keep you from being tempted to spend money.
