How much energy does the TV use?

@ Georgesplane - I hate to tell you this, but your plasma television is probably responsible for a large chunk of your energy bill. Televisions in general consume large amounts of energy, but plasma's are the worst of them all. Plasmas use almost three times the energy of a comparable sized LCD or LED. Plasmas also suck more juice as the screen size and resolution increases. This is only the tip of the iceberg. Add a device like a game console or Blu-ray player, and a surround sound system and you could end up using upwards of 1,000 watts when your system is powered on. It should be noted that all televisions, cable boxes, computers, game consoles, and stereos use electricity even when they are not running. For example, according to CNET, an HD DVR set top box uses 33 watts of electricity when it is in standby mode. that is like leaving a sixty watt light bulb on for 12 hours a day, 365 days a year. Think of the energy drain from all of a home's audio, video, and computer equipment combined. Premium electronics comes at a price, but there are ways to reduce their consumption. Use a programmable outlet or power strip to connect all of your appliances. This will allow your appliances to automatically shut down during the night and re-boot in the morning. They run anywhere from $20 up to about a thousand depending on how many outlets you want them to control, and the units capability. The more advanced units can literally set timers for all of the devices in your home for up to a year, and as precise as to the second. Another thing that you can do is be sure that your TV is properly calibrated. A television that is used at the out-of-the-box settings can use twice the energy as a properly calibrated television and only last twice as long. Calibration discs can usually be found for $20, and instructions can be found online. There is a price to pay for premium audio video equipment, but with the proper planning your efficiency can be maximized. I hope this helps.

What about a television and all of the auxiliary components that go with it? Does screen size contribute to the amount of energy used by a television? I have a plasma television, but I never really thought about how much energy it consumes. I also work from home and spend a lot of time on the computer. I have replaced all of the light bulbs in my condo with compact fluorescents, turn off all lights when I leave, and set my HVAC unit to 80 degrees when I am gone, but my electricity bill still seems high. I have always wanted to get an energy audit, but I guess I am a procrastinator when it comes to these things. Can anyone fill me in on the details of the energy consumption of an audiophile?

foregoing preheating before baking is a good idea but in natural gas or electric ovens you have to, otherwise the baked goods will have doughy insides and hard outsides. propane ovens heat up quickly and you can forgo preheating.
