My house uses around 3-4MW/mo. I hyper optimized when I had true spot pricing before Griddy energy was disbanded by the state. My bill was extremely low compared to what I pay now.

Average US residential consumption is under 1MWh/mo so you are definitely not a typical customer.

What? My house used 4 MWh a year in 2020, with two people working from home and two kids. Of these about half (IIRC) is self-produced solar. Stove and heating are gas and I do not have a tumble dryer, but does that justify a 10x difference??

  My home uses over 2MWh/mo over the summer, I think our peak bill this year was ~3200kWh. Average highs these last few months has been around 100F or so and very sunny, with at least one month >100F for the high every day. Its finally "cooling off" around here, with our highs being in the upper 90s most days. Cooling >2000sqft of space, even with some decent insulation and keeping the AC to 78F in the day, uses a lot of energy. It uses ~30A @ 240V, so ~7.2kW. If it had to run 12 hours in a day, that's 86.4kWh in just a single day. Doing that for a month straight, that's 2,592kWh. I was going to write up the math on how much my pool pump uses, but honestly it kind of turned into peanuts compared to the amount our AC usage is. The pump is 3/4HP. Running ~600W on the schedule of 8 hours a day + 12 hour once a week shock it really only worked out to 172.8kWh/mo of usage. Still though, that's 52% of your entire usage for just my pool. Last year we probably used ~3,000kWh charging the EV. That's on average 250kWh/mo.

    To be honest I wonder if those are good places for humans to live in, at all.

      There's only a narrow band of land then where we would be able to live without expending large amounts of energy to stay warm or cool. Colder places use just as much if not more energy in wintertime. They just don't often use it as kWh from their electricity provider so they don't normally compare it this way. Instead of electricity they burn natural gas or propane or fuel oil or even wood pellets to heat their homes. Many people in this chat which talk about having pretty low energy usage then acknowledge they heat with gas. For many, changing to heat pumps would drastically increase their electric bills in the winter offsetting their gas bills. Just look at my comparison of energy usage of my heat pump cooling my home compared to the energy usage of other big usage areas. It's not even close. Running a heat pump for 12 hours to keep the house warm would be a similar amount of energy usage. It's the same tech. Raising the inside temperature from 0F to 70F (70F degrees of difference) takes more energy than cooling from 100F to 70F (30F of difference). So a place that spends half the year around 100F but then is close to comfortable inside for the other half requires less energy than a place that gets down to 0F half the year and then is close to comfortable the other.

        My gas usage is 1400 m3/year, corresponding to roughly 15 MWh/year. A condensing boiler would lower it to at most 10 MWh, even less for a heat pump. Add in the electricity, and that would still be roughly 1 MWh/month or a third of what the user above mentions.

        It's rather hard to compare unless we know the spaces involved. My energy usage was significantly less when I was on the ground floor of a large apartment complex, using maybe 500kWh/mo at the highest. But I had less than half the space I do now, no private yard, no private garage. I couldn't install amateur radio antennas however I wish. I couldn't make changes to the unit however I wish. My family has grown and I now work from home significantly more than before. I don't need to use as much energy as I do, I could go back to living in a much smaller space and not have all the private spaces and rights I have now. But I'd rather not raise a family in <900sqft when I can afford not to and I get a lot of enjoyment of the private spaces I have. Sure, we could get everyone to use <500kWh/mo, even if we don't have to ask everyone to move to the narrow space that's close to room temperature year round. But that would mean massive changes in a lot of lifestyles, limiting a lot of people to far less space and property rights than they've been used to.

  It's 90-100F from 9AM to 9PM (and sometimes longer than that) with 100% humidity 3600sqft mutli story house. 2 adults, 2 kids at home. 2 electric vehicles.

What are are you using that much power for? I can’t think of much that uses that much per that you can shift to time of day pricing, perhaps pottery kilns? Even 2MWh per month is enough to drive 2 EV’s around 50,000 miles per year each. If you’re very flexible with time of day rooftop solar could probably save you quite a bit.

  Just having my 4x3090 constantly running deep learning experiments consumes 1MWh/month. And that's GPUs only.
  - Retric 4y ago
    Except constantly running can’t benefit from time of day pricing. Essentially it needs to be some 15kWh load that only needs to run for 6 hours per day.

      If the price changes are large enough, you can just buy an extra board and have them at the best half of the time.

        I think you would be better off buying a 2 Tesla power wall to load shift the demand vs 4x as much computer equipment that’s quickly outdated.

Your average constant electrical load is 4.2-5.5 kW? That seems excessive, are you running crypto miners or a small manufacturing operation/welding shop out of your home or something?

I thought mine was high at about 1.6 MWh per month!

  It does sound high too if that's any consolation! My electricity usage is 1.3 MWh per year, though heating is then a separate energy bill.

> My house uses around 3-4MW/mo. This sounds.. astonishing. How can one consume so much in a house? My average is around 500 kWh which results in a $200+ bill.
