It is realtively easy to calculate what energy is used to take it from one point to another. Had to make a few assumptions here and there. In the end...for me, there would be no comparision with NG...but a NG set up is not nearly as cool as your set up!

Has anyone gotten any actual electric data? I was planning to add one of these to my control panel just for curiosity:
http://www.ebay.ca/itm/Single-Phase-...item35c0ea87d0

Theres lots of them on eBay for cheap.

US biphase power is going to be 240VAC, not 220VAC. Warning.

Says 50Hz. Might not read RMS power correctly at other frequencies. Warning.

Appears to have a 10A limit. Warning.

I did not intend for someone to use that exact one, I quickly googled it to find an example to post.

If you look you can find one suited to your setup, of course it is still un-certified Chinese crap, so you have to be willing to accept that.

EDIT: Just re-read your last line. 10(50A) does not mean it has a 10A limit. This is how power meters are rated Basic Current (Max Current). It has to do with different regulations/standards and how the performance/accuracy of the meter is rated.

So by your numbers, even if you assumed only 50% efficiency on electric, which I think is way low, you'd work out to $1.60 per batch in power cost, which is still less than half of Propane. That's good to know, I suppose, not that I was considering going back to propane!

I get weekly reports with a graph from the electric company (smart meter) Brew days are about $1.50 more in the summer and about a dollar in the few weeks we call winter.

Kitchen brewing on a stove top.

The reality is we are talking about a few bucks difference at most for the power. In the end NG is going to be cheapest. Let's face it, all-electric is way cooler and propane is just not that good of a deal unless you buying in bulk. However, don't be naive to think the upfront cost for all-electric is going to pay for itself anytime soon. Again...who cares, it is about simplicity and repeatability...right?!!

So all this really shows is that living in California sucks.

We all would brew beer at home no matter what the cost. My wife is happy that I have this "inexpensive hobby" now. The last one I had was vintage aircraft. Brewing is much less costly than flying. Safer too.

Yeah, but screaming machine gun sounds at your intended target has got to be more fun with aircraft controls in your hand vs. holding a mash paddle.
