Sustainable Digital Signage: Energy Efficiency and the Real Cost of Running Commercial Screens
Digital signage running costs are not mysterious. Start with the screen's wattage, multiply it by the hours it operates, then apply your electricity tariff. From there, better scheduling, brightness control and hardware selection can reduce unnecessary consumption.

Running Costs
Commercial Displays
Reducing signage energy consumption starts with specifying the right display, brightness and operating schedule for the location.
How much electricity does a digital signage screen use? The answer depends on its wattage, brightness, screen size and operating hours. A screen drawing 150 watts for 12 hours a day uses 657 kWh of electricity over a full year.
For organisations operating tens, hundreds or thousands of displays, those individual figures quickly become relevant to operating costs, procurement decisions and sustainability reporting.
The answer is not simply to choose the dimmest or smallest display available. A screen still has to perform its job. A shop-window display that cannot overcome daylight is not efficient merely because it consumes less power. It is simply under-specified.
The better approach is to understand what drives digital signage energy consumption, calculate the real running cost and then remove unnecessary operating hours and excessive brightness without compromising the application.
Running Cost Formula
How to Calculate the Running Cost of Any Digital Signage Screen
You only need four figures: screen wattage, operating hours per day, operating days per year and your electricity unit rate.
Energy Formula
Watts × hours per day × operating days ÷ 1,000 = annual kWh
Annual kWh × electricity unit price = annual electricity cost
Worked Example
Imagine a commercial display rated at 150 W and operating for 12 hours every day:
Power: 150 W
Daily operating time: 12 hours
Days: 365
Annual consumption: 657 kWh
At 24.3p/kWh: approximately £159.65 per year
The 24.3p/kWh figure above uses the Department for Energy Security and Net Zero's provisional 2025 average electricity price for UK non-domestic users across all consumption bands, including the Climate Change Levy. It is an illustration, not a quote for your business.
Your actual tariff may be higher or lower, so the most accurate calculation always uses the unit rate shown on your organisation's electricity contract or bill.
Understand the Specification
What Drives Digital Signage Power Consumption?
Two commercial displays of similar physical size do not necessarily consume the same amount of electricity. The panel design, brightness, backlight, processing hardware and operating conditions all affect the result.
Screen Size
Larger panels generally require more energy to illuminate a greater display area. That does not mean a smaller screen is automatically more efficient for the project. If customers cannot comfortably see the content, the display is not performing effectively.
Brightness
Brightness is measured in cd/m². Displays used in standard indoor environments can operate at lower brightness than screens designed for bright interiors or window-facing installations. Driving the backlight harder normally increases power demand.
Backlight and Panel Technology
Different backlighting systems and panel designs use energy differently. Features such as local dimming can reduce output in darker image areas on compatible hardware, while standard LCD backlights may remain active even when the content itself looks dark.
Operating Hours
Operating hours are one of the simplest variables to control. A display consuming 150 W for 24 hours uses twice the energy of the same display operating for 12 hours, before standby consumption is considered.
| Example Display | Brightness | Typical Power | Example Use |
|---|---|---|---|
| Moove 43" High Brightness | 700 cd/m² | 121 W typical | Bright commercial interiors |
| Moove 55" Commercial Monitor | 500 cd/m² | 138 W typical | General indoor signage |
| Moove 65" High Brightness | 700 cd/m² | 194 W typical | Large bright indoor environments |
The figures show why specifications should be compared model by model rather than assuming every screen of the same size has identical energy use. Explore 700 cd/m² commercial monitors when higher indoor brightness is required.
Use Brightness Intelligently
Do High Brightness Displays Use More Electricity?
Generally, higher display brightness requires more power because the screen has to produce more light. This is why a window-facing display should not be specified purely from the lowest wattage figure.
The goal is to use only as much brightness as the environment actually requires. A shopfront at midday and the same shopfront after sunset do not necessarily need the same output.
Compatible displays with ambient-light control or automatic brightness adjustment can reduce output as the environment gets darker. This can improve comfort, reduce unnecessary energy use and avoid an excessively bright window after dark.
For demanding environments, compare purpose-built high brightness displays. For bright indoor locations, the Moove 43 inch 700 cd/m² display is rated at 121 W typical power consumption with deep standby of 0.5 W or less.
Remove Waste First
Seven Ways to Reduce Digital Signage Energy Costs
1. Switch Screens Off When Nobody Needs Them
The cheapest operating hour is the one you do not need. If a reception closes at 7pm and nobody can see its screens until 7am, leaving those displays fully active through the night adds consumption without creating value.
Many commercial display products include power timers or automatic on/off functions. Content can also be prepared around real trading hours using digital signage software. Confirm device-level power-control compatibility for the exact display before relying on CMS control.
2. Reduce Brightness Outside Peak Daylight
A screen configured for the brightest part of the day does not always need that same output all evening. Where the hardware supports it, scheduled or sensor-based brightness control can avoid unnecessary output.
3. Use Ambient Light Sensors Where Appropriate
Automatic adjustment removes some of the guesswork from brightness management. This is particularly relevant to window and semi-outdoor installations where ambient light changes significantly during the day.
4. Do Not Assume Dark Content Always Means Low Power
Dark creative can look refined and reduce visual glare, but energy savings depend on the display technology. On a conventional LCD, the backlight may remain active behind dark pixels. Displays with local dimming or emissive technology can respond differently. Treat content colour as a design decision first, not a guaranteed energy-saving measure.
5. Specify the Right Screen Size
Avoid oversizing by default. Determine viewing distance and the smallest important information people must read, then select a screen that solves that requirement.
6. Avoid Unnecessary External Hardware
A display with a built-in system-on-chip may remove the need for a separate PC in some applications. Where an external player is required, choose hardware appropriate to the workload rather than using an oversized desktop computer for simple signage playback. ScreenMoove also supplies a dedicated digital signage media player.
7. Retire Screens That No Longer Have a Job
Screen estates grow over time. Periodically audit whether every display still has a clear audience and purpose. An unused screen left running because nobody owns it is pure operational waste.

Look Beyond the Meter
Commercial vs Consumer Displays: The Lifecycle View
Sustainability is not only about the wattage shown on a datasheet. Replacement frequency, repairability, warranty support and whether the hardware is suitable for its actual operating schedule all affect the lifecycle of a screen estate.
A domestic television can appear inexpensive at purchase, but it may not be designed for portrait operation, long daily duty cycles, commercial thermal conditions or central control. Using hardware outside its intended environment can make the initial saving less meaningful if replacement is required sooner.
Commercial screens are designed around professional applications, with models available for extended or continuous operation and warranties structured around business use.

End of Life
Commercial Displays, WEEE and Responsible Recycling
Eventually every display reaches the end of its useful life. In the UK, display screens used for advertising or information fall within electrical and electronic equipment rules, and waste displays need to be handled through appropriate WEEE routes.
Replacement should not automatically mean disposal. Where hardware remains functional, redeployment or refurbishment may extend its useful life. A screen removed from a customer-facing window might still be useful for internal communications or a less demanding location.
When reuse is no longer appropriate, work with compliant collection and treatment routes rather than sending electronic displays into general waste.
ScreenMoove's support and maintenance team can also help with the operational side of maintaining a commercial display estate.
Measure What You Operate
Including Digital Signage in Energy and ESG Reporting
A multi-site screen estate is easier to manage when its energy assumptions are documented. Keep a basic inventory containing screen model, quantity, rated or measured wattage, operating schedule and location.
That gives operations and sustainability teams a defensible way to estimate annual consumption and identify locations where excessive operating hours or brightness settings may be creating avoidable cost.
For larger estates, use actual meter or device data where available rather than relying permanently on headline specifications. The objective is to turn screen energy from an unknown overhead into a manageable operational metric.
Digital Signage Energy Consumption FAQs
How much does a digital signage screen cost to run per year?
Multiply the screen wattage by daily operating hours and annual operating days, divide by 1,000 to get kWh, then multiply by your electricity rate. Actual costs therefore vary by screen and tariff.
Do high brightness displays use more electricity?
Generally, higher brightness requires more power. The correct approach is to specify enough brightness for the environment and reduce unnecessary output through appropriate brightness control where supported.
Should digital signage screens be switched off at night?
Usually, if nobody needs to see them. Screens serving shop windows, transport locations or other evening audiences may still have a purpose after normal opening hours, so schedule around the actual audience.
Is digital signage more sustainable than printed signage?
It can be advantageous where content changes frequently, but there is no universal answer. Electricity use, equipment lifecycle, manufacturing, maintenance, replacement frequency and the amount of printed material avoided all affect the comparison.
How should old commercial displays be disposed of?
Reuse or refurbishment should be considered where practical. When a screen has reached end of life, use an appropriate WEEE-compliant collection, recycling or treatment route rather than disposing of it as general waste.
