Looks like I'm using just over 10MWh/year... somewhat above average! I think there are 4 use cases for higher electricity consumption in households: distributed computing/mining, tropical fish/reptile keeping, and erm... plant growing apparatus. I fit most of those categories...
In Washington state, there are several large datacenters in and around Wenatchee to take advantage of the nearby, cheap hydro power.

https://www.electricitylocal.com/sta...ton/wenatchee/

3.44 US cents / kWh for commercial, or 3.22 US cents/kWh for residential, or a super low 2.18 US cents for industrial. I think I pay about 10 cents where I live, by way of comparison.

So you might consider if there's a break even or even a cost savings by co-locating in such a place compared to paying your home rate for power.

which equates to 4.1841666.... cents per megaJoule. I think my annoyance is that if I only had to pay electricity without taxes it would be about $22-24 for 2 months while working, where as with taxes and base charge and taxes on that and yes I get a rebate partially) it's like $45 per 2 months. my hook up was like this:

21.66, base fee ( charges basically to keep the account open/make them money).
22.50, 152 kWh at 14.8 cents ( now it would be 15.063 cents) each
28.00, connection charge
10.82, HST
4.42, rebate

total $78.56

kind of annoying. my lowest electricity use that's easy to see is 141 kWH and the bill was down to $41.82

Last time I reviewed it, from a pure crunching point of view, I think there are some cloud providers that are about break even with running my own, with the difference the heat goes elsewhere. Right now it is winter and I do run a certain background level as my main home heating. On the flip side, almost everything is off in summer. This assumes all costs with buying and running for several years working life in the TCO.

The other "problem" is I find tinkering with hardware to be one of my interests. Can't do that in the cloud! While it goes against optimising for efficiency, I do find it fun doing a bit of overclocking. Just started doing extreme tuning of ram. For a 4 GHz quad core CPU, I got 4096k FFT benchmarks of 170 iter/s at 2133 ram, to over 253 iter/s with manually tuned 3866. Nice little increase! Also overclocking CPU to 4.7 GHz gets it up to 282 iter/s but I'm really turning up the voltage therefore power output there. It'll be fun to get some fast units out for the next PrimeGrid challenge on bigger LLR based units.

Indeed! I've been toying with the idea of buying a quad core PowerPC system just to toy with it. Horribly inefficient and slow, but...

I estimate, very roughly, based on USD 0.12/kWH, that my computer alone, drawing 850 W on the mains, 24/7, costs about USD75 per month. When occasional air conditioning ended was the first time in at least a year that we got under USD100, for a 2 bedroom apartment. We hit over $150 when highs were getting toward 90 F, and lows hung around 80 F.

We modestly A/C about half of the public areas, and Dan has a small unit in his room for hot nights. I prefer open windows and lots of air movement, myself. A big window fan on the back porch, and plenty of windows open in the front and side rooms takes care of a lot of the 'open window' season. Ceiling and other circulating fans rounds things out.

This time of year, the heat output of the computers is a feature, not a bug.

Wow! This is 20 kWh per day, give or take a tiny bit. I worry when mine draws more than 300W from the wall. I have to run Prime95 and a GPU process in tandem to get this high. Just waiting to get that 1080 to cut into the GPU a bit. Sorry for going off-topic!

The current residential rate for Duke Energy in Indiana is 0.128 per kWh. This is a very small reduction compared to last month. It was 0.131. I used 697 kWh during the last billing cycle. Not much A/C or heat during this time.

me and kladner talked in PM to run a similar system my electric bill would be about $236.94 ( cad but even in USD that's about 187) for 2 months of just the computer.

I discovered yesterday that my electricity company has been estimating bills based on 1.8kW constant, while I'm actually using 2.4kW constant. That's with about 140 reasonably modern x86 cores 24/7 (and a GF1080); also a fridge, I suppose.

OMG! To all concerned: The 850 W number was a mental glitch. That was taken by an AMD CPU and 2 GTX 580s, several years back. Apologies. The current draw is 490 W, or 11.75 kWh per day.

I thought I would update this since I started it. The current Duke Energy residential rate for my area is 0.1113 per kWh. In January is was over 0.13.

January was the hard month. I live in the Ohio River Valley. We had more than a few single-digit low temperatures, and two that were minus. This lasted for nearly two weeks. So, that really kept the meter outside busy.

I thought February would be better. It was not as I had hoped. One of the contributing factors is my old GTX 480. Under a load, it draws around 220W. If my calculations are correct, this translates into 5.2 kWh each day, or 158.4 kWh each month. At this pace, it made of 13% of my total usage.

In recent weeks, I have 'feathered' its usage. Perhaps, I will see a drop this month.

I get 163.38 kWh per 31 days with 24 hour usage. I also get 5.28 kWh per day though.
