This story is actually less about heating costs and more about saving energy. It also includes some information on how to cut down heating costs. My suggestion, where sweatpants and a sweatshirt in your house and don't turn the heat up as high. The bit about unplugging electrical devices is not new, but definitely helpful if your looking to cut costs.
There's a hidden price tag to the DVRs, iPods and cellphones proliferating at home. Even when fully charged or in off or standby mode, many plugged-in devices still draw, or "leak," power to operate remote controls, clocks and other needs. That costs the average household about $100 each year. The worst offenders: TVs and computer printers.
