To lower electricity use without interrupting a church’s nonstop YouTube stream, first turn off an unused display, choose Windows’ most efficient available power mode, and keep the PC awake while the encoder is streaming. Then measure the complete setup at the wall and compare it under the same streaming conditions. Change one setting at a time and confirm stream continuity and health in YouTube Live Control Room.
What to change first on a Windows 11 streaming PC
Windows 11 separates power mode, display timeout and sleep timeout. That lets you reduce some idle demand without intentionally putting the encoder to sleep. The exact labels and available choices can vary by device; see Microsoft’s power-mode instructions and screen and sleep settings guidance.
- Open Settings > System > Power & battery.
- Under power mode, select Best Power Efficiency if that option is available. Microsoft says power mode can limit background activity; it does not promise a particular reduction for a streaming workload.
- Set the display to turn off after a suitable period. If the streaming PC has a separate monitor, its screen does not need to remain lit simply because the encoder is running.
- Set sleep so the PC does not sleep during the continuous broadcast. If needed, disable sleep while streaming and use the screen-off timer independently.
- Apply the change during a controlled test, then confirm the encoder is still running and the stream remains healthy in YouTube Live Control Room.
Do not assume that every PC and encoder behaves identically with the display off. Microsoft documents the controls, not a guarantee that every streaming setup will continue uninterrupted under every power configuration. Test the actual machine before relying on the change.
Choose stream settings for the service, not a guessed power saving
Use the lowest resolution and frame rate that still provide a suitable view of the service for your audience. A mostly static pulpit shot may have different image needs from a service with frequent camera movement, text overlays or multiple angles. Also consider viewers’ connection quality, your upload reliability and whether the encoder remains stable.

Check YouTube’s current live encoder settings before changing the stream. Its guidance includes H.264, H.265/HEVC and AV1 video options, frame rates up to 60 fps, constant bitrate (CBR) encoding, and keyframe guidance. For example, YouTube lists 2–6 Mbps video bitrate for 720p at 30 fps in its encoder guidance accessed in 2026. That is a video bitrate range, not an estimate of electrical savings.
Do not infer that lowering resolution, frame rate or bitrate will save a specific amount of electricity. The available guidance does not quantify the power difference for this church-streaming workload or establish a universal best setting. Test representative audio and motion, preview the result, and monitor stream health after each adjustment.

Measure the whole setup before and after changes
Settings alone cannot tell you how much electricity a particular PC uses. Hardware, graphics and encoder workload, display, stream settings and other connected equipment all matter. A plug-in electricity usage meter or wall watt meter can measure the equipment connected through it; no particular make or model is established here.
- Decide what you are measuring: the PC alone, or the PC plus monitor and other peripherals. Keep that same set of devices connected through the meter for both readings.
- Record the baseline with the stream running and the normal encoder settings in use. Let the system reach a stable operating state before taking a reading.
- Record watts and, if the meter supports it, accumulated kWh over a defined interval.
- Change one setting, repeat the same streaming workload for a comparable interval, and record the result.
- Compare like with like: keep the PC, connected equipment, stream content and settings, and measurement duration consistent except for the one change you are evaluating.
Microsoft’s powercfg documentation describes Windows tools for managing power plans and analyzing energy-efficiency issues. It does not supply a universal setting for keeping every continuous stream running, so use it as a diagnostic resource rather than a substitute for testing your encoder and PC.

Turn measured energy use into a cost estimate
Use accumulated kWh, not a momentary watt reading, to compare energy over time. To estimate cost, multiply the measured kWh for the period by your own electricity rate per kWh. The result applies only to the equipment included in the measurement and the conditions during that period.
There is no supported universal figure for watts saved, kWh saved or bill savings from these changes on a nonstop church stream. The result depends on the particular PC, encoder workload, display, settings, operating schedule and local tariff. Do not treat another setup’s anecdotal result as a promised saving for yours.

Keep the stream reliable while testing
- Make one change at a time so you can identify the cause if the stream fails or its health worsens.
- Test during a representative stream, including the audio and movement viewers will actually see.
- Check YouTube Live Control Room after each change rather than relying only on the PC’s local preview.
- If the encoder stops or the stream becomes unstable, restore the last known-good power or encoder setting before testing another change.
YouTube recommends testing the setup and monitoring stream health. Its live-streaming guidance is at YouTube Help.
