Which term refers to energy being consumed when appliances are turned off?

Explanation:
Phantom load is the energy that's still used by appliances even when they’re turned off or in standby mode. Many devices keep small internal components powered to run clocks, memory, remote receivers, or wireless modules, so a trickle of current flows continuously. Over time this adds up to noticeable energy waste and can raise your bill. You can cut phantom load by unplugging devices you’re not using, using a power strip and turning it off, or choosing devices with very low standby power. The other terms don’t fit: a renewable resource is an energy source that replenishes naturally, loads refer to any device consuming power in a circuit, and an open electric circuit means there’s no complete path for current, so no energy is consumed.
