Koľko energie skutočne ušetrí režim úspory energie na televízoroch?
Každý televízor má na výber množstvo rôznych „režimov obrazu“. Takmer vždy existuje režim „Šetrič energie“ alebo „Úspora energie“, ktorý má tendenciu vyzerať najhoršie. Koľko energie tento režim skutočne ušetrí? Oplatí sa to použiť?
Čo je režim úspory energie?
Režimy obrazu na vašom televízore sú prednastavené pre rôzne úrovne jasu, kontrastu a sýtosti. Tieto veci môžete zvyčajne upraviť samostatne, ale režimy to všetko urobia za vás.
Režim „Úspora energie“ je jednoducho navrhnutý tak, aby optimalizoval tieto nastavenia a šetril energiu. Najzrejmejším spôsobom, ako to dosiahnuť, je stlmenie obrazovky. Režim úspory energie bude zvyčajne najtmavší zo všetkých režimov dostupných na vašom televízore.
Jednoducho povedané, či už sa to nazýva „Šetrič energie“, „Úspora energie“ alebo „Eko režim“, tieto režimy obrazu znamenajú, že váš televízor spotrebuje menej energie. Je to pravda?
Dáta
Dosť bolo rečí, poďme k údajom. Pomocou inteligentnej zástrčky, ktorá dokáže merať príkon, som zaznamenal spotrebu energie z troch rôznych televízorov vo všetkých dostupných režimoch obrazu. Všetky tri mali režim „Úspora energie“, „Živý“ režim a „Štandardný“ režim.
| Picture Mode | 43″ Scepter 1080p | 50″ Hisense 4K | 32″ Insignia 1080p |
|---|---|---|---|
| Energy Saving | 35.5w | 87.7w | 39.7w |
| Vivid | 54.6w | 115.7w | 48.2w |
| Standard | 54.6w | 115.2w | 44.7w |
| Mild | 35.9w | ||
| Theater | 82.4w | 42.2w | |
| Sport | 114.8w | ||
| Game | 114.8w |
There are some interesting results here. First of all, Energy Saving modes across the board are using less energy than the standard settings. The “Vivid” modes also don’t seem to use much more power than the standard settings—meaning it’s adjusting color more than brightness.
Two of the TVs have a “Theater” mode that had a similar effect on power usage as the Energy Saving modes. In fact, the bigger 4K TV uses the least amount of power in this mode. That’s because theater modes typically dim the display for dark rooms.
Some of the differences between Energy Saving modes and other modes are not as pronounced. The smaller 1080p TVs don’t have major differences between Energy Saving and the higher power usage modes. The difference is bigger on the 4K TV, which uses more power overall.
Does It Matter?
What can we take from this admittedly small sample size of data? First of all, Energy Saving mode is clearly doing something. That may not be super surprising—of course a dimmer display requires less energy. Still, it is nice to know “Energy Saving Mode” is not an empty marketing term.
Let’s say your electricity rate is $0.18 per kilowatt-hour (kWh) and you have a 4K TV similar to the one in the chart above. Watching TV for four hours a day with Energy Saving mode would cost around $1.90 per month/$23 per year. At the highest energy usage mode, you’re looking at around $2.50 per month/$30 per year.
You’re essentially saving $7 a year for a slightly worse picture on your TV. Are the energy and money savings enough to make that worth it? That’s entirely up to you. If you have a very large, ultra-high-definition TV, maybe it makes a big enough difference. However, if you have that TV, you probably want it to look the best it can.
Energy Saving mode could be a good “every day” mode to use while you switch back to “Standard” or “Vivid” mode for movies or other things you want to really shine. At the end of the day, it does save energy, but it may not be enough to matter to you.
