I'm more concerned about putting undo wear and tear on the unit more than the electricity it uses. Most home electronics are low draw, so I don't see much of a difference between turning it off or not.
Any thoughts?
while I am more concerned with the undo wear on things, I try to do my part on the electricty part. While that

TV might be a low draw, add up all the low draws in your household right now...then across the world! It adds up to be very substantial and we keep adding low draw electronics and appliances every year! My washer and dryer doesn't draw anything if not running. My neighbors new electronic control one does.
This is an excerpt from one of the articles I linked earlier in this thread.
Current projections indicate that miscellaneous electricity, the category in which leaking electricity falls, will account for more than 90 percent of the growth in carbon emissions from the buildings sector between 1990 and 2010 (Koomey et al. 1997). Leaking electricity arises from several sources, including: (1) components that provide a small service that is auxiliary to the product's primary function, such as powering a small display for a clock or charging a battery; (2) components for products that are always ready to be activated, such as remote control or other sensors (e.g., for telephone signal detection); and (3) components that simply waste energy, where power may be supplied to a transformer or integrated circuit that provides no useful function when the device is turned "off" (Rainer, Greenberg, and Meier 1996).
Note- this does not include the fact that we have many more things using electricty now than we have in the past. All of the items we now have that are rechargeable such as Cell phones, iPods, laptops, vacuums, mowers, drills, etc. much of which didn't use to use much or any electricty.
While I do unplug for wear and tear reasons, I try to also do my part when I can for the environment. It is easy to flip a switch on a power strip or unplug something when used only on occasion.
