Reducing Home Entertainment Electricty Usage

[green]

I am always wondering how much electricity my growing army of gadgets is costing me. I just picked up one of those measurement powerbars and scared myself with how much juice my home entertainment setups are using.I just came across the TrickleSaver (http://www.tricklestar.com) today and it looks pretty slick. You can set one device as a trigger (ie. TV) and if that device is not on then the power is automatically cut for any devices you plug into the other end of the tricklesaver. This really appeals to me (more than just a simple master on/off switch) since I don't have to adjust any habits.What kinds of interesting products/solutions are others using to reduce the impact of your tech gadgets?
