Weekly Electrical Usage from Google PowerMeter

Since I like to measure and monitor things (maybe that is why I am a DBA), and I care about the environment, I installed a TED 5000 and connected it to Google PowerMeter about six weeks ago. Every week, Google sends out an email that summarizes your power usage by day for the previous week, and by week for the previous six weeks. My latest report is shown below:

My goal for February was to come in under 400kWh for the month, but it looks like I am going to end up at around 430kWh for the month, which is not too bad for late winter. As we move into spring and average outside temperatures increase, I have a better chance of breaking the 400kWh barrier.

The sawtooth pattern in blue in the picture below shows the effect of the gas furnace blower fan coming on periodically. I think it also is an indication that I need to improve the insulation in my attic. It also may be a sign that the furnace is too large for the house. It is an Amana 95% efficient gas furnace that has worked well, but I suspect that the HVAC subcontractor that sized and installed it didn’t know what they were doing.

I am very curious what other people’s typical monthly electrical usage is in kWh, so feel free to post a comment!

    Well now, THAT is pretty darn cool. Was the TED 5000 device hard to install?

    No, once I got over my fear of being electrocuted… Actually it was not too bad, they have a video on their web site. It should be easy for an Electrical Engineer. It uses inductive pickups around the electrical cables coming in from the power company.

    I actually ended up using 404 kWh for February. Maybe I will crack the 400 kWh barrier in March as it gets warmer.

    Lol, I thought It was a typeo at 400KWh I use between 3k and 4k a month depending on how many servers are active and if the secondary AC has to work harder to cool it all down! I was thinking of installing a TED as well.

    My home is 1900 sf built in 1985. I installed a SEER 14 ac and 95% gas furnace last June. My electrical use for the past 12 months was 434 Kwh with the lowest in May at 276. My 4.15 PV array went online as of July 1 and I look forward to $20 per month electric bills.
