How to lower the cost of your garage door opener in North Carolina
- Measure actual draw with a kill-a-watt meter. Nameplate watts are often higher than real-world draw — a plug-in meter shows the true number.
- Unplug when not in use if the device has standby draw (chargers, set-top boxes, smart speakers, etc).
- Switch to time-of-use pricing if your utility offers it and your usage is shift-able.
