So why do I need a whole house electricity monitor??

I posted my install of the Current Cost energy monitor on a car forum that I always go to and a friend of mine asked me a good question.

"So what is really the purpose? Are you going to start turning things off now that you know how much electricity various things use?

Like hot tub only on Sunday from 4-4:30 Cooking only Mon, Tues, Wed...???"

and my reply was

"you make a good point, knowing what is happening in your house regarding electricity usage is useless unless you act on it.

In the immediate term, I find myself shutting off my lights in rooms that I'm not in. But the long term, it's really trying to figure out what are my energy hogs such as the fridge (10 years old), A/C (15+ years old) and dehumidifier (7+ years old).

Figure out how much they are really costing me to run and determine the ROI on a new one.

Also, I'm curious to find out what electric gadgets I have running in my house that I think are harmless or not even think about but are actually using more electricity that I would have thought. Become an "electricity detective" sort of speak.

Yesterday, I noticed that my electricity usage was spiking up more often than the day before. So I walked around and checked out the high electricity appliances and low and behold, I left the freezer door slightly ajar which was making the fridge cycle on and off more often. So if you leave things on like the oven and you forgot, you'll know because the display will show high usage."

My new monitoring gadget

I just bought a whole house electricity monitor called an Envi by Current Cost. I don't know about the rest of you out there but I have always curious as to what really goes on with my electric bill. How could it go from $60 one month to $150 the next? Yes you can try to determine if this happened during the summer then maybe it was because I was using my AC more. Or I my dream of my becoming a baker came true and I was baking more bread than Entenmanns.

But guessing can only get you so far so I jumped at the chance to buy the Envi electricity monitor. The Envi comes with a white display with power supply, 2 CT clamps and one large transmitter with battery. Installation is pretty straight forward but when in doubt hire a qualified electrician, you are working with electricity here!

After the installation, the display immediately lit up and started displaying Watts consumed at that given moment and how much it was costing per day/month at that given moment. It knows how much it costs because part of the installation of the display is entering in how much your electricity costs per kWh.

If you look at the two pictures above, the first one with 3.90KW is how much it's using at that given moment and $443/month is how much it would cost me IF my usage stayed at 3.90KW day and night for 30 days. The second photo is after I turned off that device that caused the huge spike. Notice the usage went down from kilowatts to just plain watts, 970 to be exact and $110 a month. Can you guess what this "device" was that caused such a big spike?
