DESCRIPTION2010 Earth Day presentation by Alliance staff member Tom Simchak on his self-installed power meter (TED) and how he can track energy use in his home appliances -- including his wife’s hair dryer.
- 1. Witty and/or Corny Title Related to Knowing How Much Energy Your Home Uses Whats Your Watt?!?! (sorry) Home Energy Monitors with Tom April 22, 2010
2. Three Ways I Play
- The Energy Detective TED
- Proprietary Footprints web browser-based dashboard
- Standalone display
- Viewing data with Googles PowerMeter
- Same data, different portal
- Pepcos online My Account
- Based on a guy coming out and reading the normal old electricity meter on the side of our house
3. The Energy Detective
- From Energy, Inc.
- Not very cheap - $239.95 for my setup
- A challenge to install, though can be DIY
- I managed it myself, barely
- Has its own interface software, but also compatible with Googles PowerMeter
- One second data intervals
- Nearly real-time
4. 5. 6. 7. 8. Fridge from CEE Super-Efficient Home Appliance Initiative list 9. 10. 11. 12. Toaster Dehumidifier Fridge 13. 14. 15. Google PowerMeter
- Public API, so in theory any clever IT engineer can make devices work with it
- Two commercial stand-alone devices presently work with it
- One in US (TED), one in Europe
- Several utilities have smart meters that work with it
- Teething problems, like providing old data
- Still in development
- Some quirks, some bugs
- Ten-minute intervals
16. 17. 18. Budget function a bit odd Also at home vs. not at home Cant see refrigerator cycling on and off 19. 20. Pepcos Online Tools
- Based on regular meter-reading data
- Either guy comes once a month to read it or someone occasionally reads it and its otherwise extrapolated.
- Basically a one-month interval
- Limited functionality, buggy
- Requires you to turn off some browser security settings
- Some utilities provide more info
- OPower, an Alliance Associate
21. 22. Lessons Learned
- Resistance heating uses a lot of energy, but not often
- Toaster, electric kettle (lots of tea), hair dryer, hair straighteners
- We have natural gas water heater, air heater, and cooking which none of these systems measure
- The refrigerator uses a lot of energy, though, in theory, a lot less than most
- We already did what we can realistically do
- The dehumidifier uses quite a lot
- I need to clean gutters and regrade the yard
23. Lessons Learned
- So have I taken any particular action based on this data?
- Coming soon to ase.org!At Home With Tom!
- High-tech guilt-trip?
- Popular appeal?
24. Thank You!
- You know where to find me
