Monitoring Home Energy Usage

In our book "The Frugal Prosumer Philosophy" we talk about the Kill-a-Watt electric meter for monitoring how much electricity you are using. It is the most inexpensive way to do that (cost about $25 dollars.) But the down size is you can only measure something that is plugged into a 110 electric socket. That means you can measure your ceiling lights, furnace fan, central air, etc.

Now for the first time there are some items out there that can do this that don't cost hundreds of dollars. One of them is the Blue Line’s PowerCost Monitor for around a hundred dollars.

Here is a brief review by someone who tried it out.
