In hopes of meeting my goal to reduce our household electricity use, I just bought a Smart Strip LCG3 power strip. At $40, this is not cheap. But, it seems like it's worth trying. It is supposed to actually turn off your computer and electronics if they are idle for more than 1 hour.
After some careful thought, I decided to start with only one of these. My hubby has a computer, monitor, playstation, big screen TV, and speaker set-up in the basement that I suspect is a huge electricity vampire. Even when they are "off" these items are never really off, they are on standby. So, I plan to install one of these smart strips in this area. If it works well, I may buy one for the stereo system upstairs and possibly a smaller version that I can plug all of the small kitchen appliances into.
I know that reducing electricity usage to a manageable level is going to be very difficult now that our furnace is an electric heat pump (even though it's geothermal). This is what I hope will be one step in the right direction.
