Electric garage doors do not use a significant amount of electricity. Their primary power consumption occurs during operation, which typically lasts a few seconds each time the door is opened or closed. On average, an electric garage door opener uses about 100 to 200 watts while active. This consumption is relatively low, especially since it operates for brief periods.

When idle, most electric garage door openers remain on standby, consuming only a small amount of electricity—usually between 3 to 10 watts per hour. This minimal standby usage ensures that the opener is ready for immediate activation.

If energy efficiency is a priority, consider newer models equipped with energy-saving features like low-power standby modes or LED lighting, which reduces overall consumption. Regular maintenance can also help keep the opener functioning efficiently.
