We’re happy to share the new official **Energy Saver extension** for Defold! 🔋🌱

[![energy_saver_defold](https://forum-defold-uploads.b-cdn.net/original/3X/b/0/b03d6527fb8072bd28071eaa752a793b30d23a35.png)](https://defold.com/assets/energy-saver/)

The extension helps games reduce unnecessary power consumption when the player is inactive, particularly useful on mobile, handheld, battery-powered devices, but also for reducing heat, fan noise and energy use on PCs, consoles and other devices.

It can automatically apply several power-saving measures after configurable periods of inactivity:

- reduce the game’s FPS
- dim the screen
- disable rendering entirely

As soon as the player becomes active again, the game can return to its normal state. Power-saving measures can also be temporarily disabled when needed, for example during cutscenes or other sequences where inactivity should not trigger them.

An important part of making this useful is a change coming with **Defold 1.13.2** : when a lower update frequency is set, the engine loop no longer busy-waits for the next frame. This means reducing FPS with `sys.set_update_frequency()` can actually reduce CPU activity and power consumption instead of simply waiting actively for the next frame.

This can be especially useful for games with idle screens/menus, turn-based games, pause states, or other such situations.

The extension was developed in collaboration with the [Sustainable Games Alliance](https://sustainablegamesalliance.org/), which works with the games industry on practical approaches to improving energy efficiency and player experience. This lays a solid foundation for Defold being a sustainable game engine.

SGA has also published an Energy Efficiency Guide and works on power-saving practices such as reducing frame rates during inactivity, screen dimming and avoiding unnecessary rendering - you can [read more about it here](https://sustainablegamesalliance.org/services/optimizing-energy-efficiency/).
