Nowadays, energy efficiency is more important than ever with the climate crisis and an unstable cost of living, it makes sense to cut down on energy usage where you can. Don’t worry, this doesn’t mean you will have to stop using your TV or make any massive changes. The energy efficiency of smart TVs is considered when making them to make sure they are as efficient as possible.
In this guide, we’ll break down what makes a TV energy efficient, what to look out for, and highlight some of the best options available on Amazon right now. Including the following;
What Makes a Smart TV Energy Efficient?
There are a few key factors that determine how much power your TV will use:
- Eco or Energy Saving Modes – Most modern TVs come with built‑in settings that automatically reduce brightness, dim the backlight, and switch off unnecessary processing features.
- Energy Ratings – Every TV sold in the UK comes with an energy label, ranked from A (most efficient) to G (least efficient). While very few TVs hit an “A” rating, models with a D or E are considered among the best performers.
- Screen Size – Bigger screens naturally use more power. A 75‑inch TV will always consume more energy than a 43‑inch, even if they share the same technology.
- Display Type – OLED and LED panels are far more efficient than older plasma or LCD models. OLED in particular is excellent, as each pixel can switch off individually, saving power when displaying darker scenes.
- Brightness Levels – Ultra‑bright TVs look great in daylight, but they also use more energy. Dialling down brightness not only saves power but also reduces eye irritation.
