There was a thread on TVs and how they use electricity when turned
off. DOE is researching the issue of appliances using energy when in
"standy mode." You might think this is minimal, but when you add up
the TV, game consoles, stereos, DSL/cable routers, computers, etc. DOE
says it can be 10% of your energy usage. There are ways to reduce
energy usage anyway by unplugging less used appliances. Putting
computers in hyberate mode is better than a screen saver. Not sure if
all appliances are energy-star compliant.
