So my KW/h rate has gone from 0.0817 to 0.1315 in the last two years. I went from paying $219 a month for electric to $450+ and I could no longer justify this and needed to take action - this is what I have done.

  • For storage I had 3-R710’s with 6-4tb drives each, I moved to a new to me QNAP with 6 brand new 20tb WD Red drives and moved all of the data to that and unplugged the R710’s.
  • I moved ESXi and Guests from an r630 to a new to me Dell Precision 3650.
  • I moved PFSense from an R410 to a new to me Protectli Vault micro appliance.
  • I retired the Cisco Catalyst 3560-X in favor of a new to me low power HPE 48p selectable POE switch.
  • I put my backup host (Dell Optiplex with a 4th gen i5) running Veeam on a smart switch. I have a script that shuts the computer down after the backups complete and then an hour later the smart switch powers off. The smart switch powers on the computer and I have the bios set to power on the computer after a power outage. This happens three times a week.
  • I set a group policy to set the Windows power plan to balanced from high performance for my computer and my GFs computer. This has dropped both of our computers from using 150w+ to 20-30w at idle. Identical computers 11900k/3080ti EVGA FTW3
  • My torrent host is another Dell Optiplex with a 10th gen i5, I have that set to Windows power saver mode and max 45% CPU / min 0%, it uses less than 1w at idle now.
  • I recently install a whole home energy monitor into my main panel and integrated it into HomeAssistant so I can log and monitor. (see imgur picture)
  • On top of all of this I have set my water heater from 145F to 135F, unplugged unused devices in unused rooms too.

I am happy to say my mini production environment is now running stronger and cooler, the ambient air temp in the basement has dropped from 86F to 70F. The best part of this is I just got my latest energy bill. I went from $510 last month to $270 this month! Nothing else has changed other than what I have posted here today.

Check out this screenshot of the energy monitor, with both gaming desktops, both fans, and all the basement lights and TV/AV receiver powered right now, I am only using 600ish watts! Before that I was using over 2.5kw/h

    What are you running in the Precision 3650 and what was the cost for it?
